AB  - Microbial degradation, compared with many other degradation processes, is the most important
pathway for the depletion of triazine herbicides in soil. The aim of this study was to determine the
growth potential of Pseudomonas sp. CY in the presence of atrazine and additional carbon (sodium citrate) and nitrogen (ammonium-nitrate) sources. The experiment was performed with five treatments: i) 100 mg/L atrazine (control); ii) One hundred mg/L atrazine + sodium citrate (0.3 %,w/v); iii) One hundred mg/L atrazine + sodium citrate (0.3 %, w/v) + ammonium nitrate (0.6 %, w/v);iv) Atrazine (300 mg/L) + sodium citrate (0.3 %, w/v) and v) Atrazine (500 mg/L) + sodium citrate (0.3 %, w/v). The bacterial count was determined after incubation (7 days at 30°C) using the agar plate method, while atrazine degradation was determined by measuring the optical density at 221 nm.
Pseudomonas sp. CY can partially utilize atrazine as the sole source of carbon and energy. The
highest values of the bacterial count were determined at the highest initial atrazine concentrations; however, bacterial growth was not detected in these treatments. A significant impact of citrate on bacterial growth and atrazine degradation was observed, while the addition of nitrate decreased the atrazine degradation rate. This study confirmed that Pseudomonas sp. CY can be used as a prominent candidate for the remediation of atrazine-affected environments.

AB  - Male piglets are castrated primarily to avoid the unpleasant boar taint in meat, and additionally for the predisposition of castrates to accumulate fat and for their lower risk of developing unwanted behaviours. There are two main strategies available for withdrawing from surgical castration: one is immunocastration and the other is to raise entire male pigs or boars. Additionally, raising intact boars is more profitable because of the production of carcasses with lean meat and better feed conversion. Boars (compared to castrates) exhibit more aggressive, sexual, damaging social behaviour and reduced feeding behaviour with a lower prevalence of sickness behaviour as a result of good health and low susceptibility to chronic inflammation. In this review, the behaviours specific for boars as a result of sexual maturity are reviewed, with an overview of differences in the behaviour of surgically castrated barrows, immunocastrates and boars reared in group-housed systems. The raising of boars allows for good welfare of these animals in early life, but later, on reaching sexual maturity, the welfare of boars can be diminished because of their propensity to aggression and more mounting behaviour than castrates. Innovations in the breeding and management of boars are needed to improve their performance and to reduce welfare implications of these animals raised in social groups, and in particular to minimize deviant behaviours towards pen mates.

AB  - Lameness is a multi-factorial condition that depends on managerial as well as genetic variables, but often is related to legs and feet condition of the animals. The aim of the study was to give an overview of legs and claws condition and the presence of lameness in sows at one industrial farm. Total 130 animals (90 dry i.e. pregnant and 40 lactating sows) were observed. The occurrence of leg joints swellings, than claws condition (toes length, dew claw condition, cracked wall) and lameness (in animals in group boxes) were visually recorded and then classified according to the appropriate protocols. Findings proved the occurrence of one or more of examined conditions in 40% of pregnant sows and in 45% sows in lactation. In more than 20% of pregnant sows lameness was presented. There was statistically significant positive correlation between the occurrence of lameness and leg swellings and between lameness and claw condition in pregnant sows (in both cases p lt 0.0001). The results show that lameness is a significant problem in the studied farm. In general, more attention should be given to monitoring of sows' physical condition and behaviour, to minimize the occurrence of welfare problems and to reduce production losses.

AB  - The aim of this study was to find out is it possible to presume success of boars sperm cryopreservation, based on controlled exposure to heat stress and to investigate in vitro quality parameters of frozen/thawed sperm of previously selected 6 boars with good results (group 1) and 6 boars (group 2) with bad results on thermo resistance test (TT). In this investigation, ejaculates of 12 chosen of 75 AI boars (Landrace, Large White, Pietrain and Durock breeds) from SVC Velika Plana (Serbia) were used. Tolerance to heat stress was performed by Schaetz (1963) method. Ejaculates were extended with Androhep plus (1:1) and kept during 60 minutes on 41oC. In cryopreservation of boars semen Westendorf et al. (1975) method, modified by Bwanga et al. (1990). Very significant changes of progressive motility rate were observed after spermatozoa exposure to controlled thermal stress. High correlation coefficient of progressive motility rate of both groups of boars, but higher in group 2 for progressive motility rate after thawing and after heat stress treatment was established. Average progressive motility rate of all 12 boars did not differ before and after thawing. Presence of boars of all breeds represented in the SVC (Large White, Landrace, Duroc and Pietrain) in both quality groups confirms the assumption that suitability for cryopreservation of sperm is individual trait.

U istraživanju su korišćeni ejakulati 12 od 75 nerastova rasa: landras, veliki jorkšir, pijetren i durok (L, J, P, D) iz SVC Velika Plana, odabranih na osnovu testa termorezistencije (TT) i svrstanih u dve kvalitetne grupe. Ispitivanje stepena termorezistencije ejakulata u razređenju Androhep-om plus 1:1 60 minuta na 41 oC, je izvedeno metodom po Schaetz-u (1963).

Ustanovljen je visok koeficijent korelacije kod obe grupe ali ipak nešto viši kod nerastova 2. grupe za odnos procenta progresivne pokretljivosti spermatozoida posle odmrzavanja i progresivne pokretljivosti posle izlaganja temperaturi od 41oC. Prosečna progresivna pokretljivost spermatozoida svih ispitivanih nerastova se nije značajno razlikovala pre i posle zamrzavanja. Slučajni raspored nerastova svih rasa zastupljenih u SVC (Jorkšir, Landras, Durok i Pijetren) u obe kvalitetne grupe potvrđuje pretpostavku da je pogodnost sperme za krioprezervaciju individualna osobina. Za uspešnu krioprezervaciju sperme nerastova je neophodna prethodna selekcija potencijalnih donora na osnovu rezultata ispitivanja standardnih parametara kvaliteta i testova u kojima se spermatozoidi in vitro izlažu različitim kontrolisanom stresu.

abstract = "The aim of this study was to find out is it possible to presume success of boars sperm cryopreservation, based on controlled exposure to heat stress and to investigate in vitro quality parameters of frozen/thawed sperm of previously selected 6 boars with good results (group 1) and 6 boars (group 2) with bad results on thermo resistance test (TT). In this investigation, ejaculates of 12 chosen of 75 AI boars (Landrace, Large White, Pietrain and Durock breeds) from SVC Velika Plana (Serbia) were used. Tolerance to heat stress was performed by Schaetz (1963) method. Ejaculates were extended with Androhep plus (1:1) and kept during 60 minutes on 41oC. In cryopreservation of boars semen Westendorf et al. (1975) method, modified by Bwanga et al. (1990). Very significant changes of progressive motility rate were observed after spermatozoa exposure to controlled thermal stress. High correlation coefficient of progressive motility rate of both groups of boars, but higher in group 2 for progressive motility rate after thawing and after heat stress treatment was established. Average progressive motility rate of all 12 boars did not differ before and after thawing. Presence of boars of all breeds represented in the SVC (Large White, Landrace, Duroc and Pietrain) in both quality groups confirms the assumption that suitability for cryopreservation of sperm is individual trait. According data analysis, sperm deep freezing success requires previous selection for potential donors, which have to be consider standard quality parameters testing and controlled stress exposure tests., Cilj rada je da se ustanovi da li moguće odrediti da li je sperma nerasta pogodna za krioprezervaciju da se na osnovu izlaganja spermatozioda kontrolisanom toplotnom stresu i da se ispitaju in vitro parametri kvaliteta odmrznutog semena dve grupe od po 6 nerastova čije je seme dobro (1. grupa) ili loše podnelo toplotni stres (2. grupa).

AB  - Rattus norvegicus is a synanthropic species living almost exclusively around facilities for keeping domestic animals. This three-year research focused on options for reducing economic damage caused by this rodent species in stables for heavy milking cows by testing preparations with active substances of various origin. It involved an environmentally friendly product based on sodium selenite 0.1%, a cholecalciferol-based natural product 0.75%, as well as anticoagulant rodenticides containing the active substances bromadiolone 0.005% and brodifacoum 0.005%. These preparations were formulated as granules, plate bait or grain bait. The environmentally friendly sodium selenite product achieved 76.2% efficacy in the first year of research, 70% in the second, and 67.5% in the third. The synthetic products based on bromadiolone and brodifacoum demonstrated high efficacy in all of the three experimental years and in all three formulations. The cholecalciferol rodenticide had 71.4% efficacy in the first year, 68% in the second, and 67.7% in the third. The data show that the environmentally safe product had a lower efficacy due to high rodent abundance and inadequate epidemiological conditions existing on the farm of heavy milking cows, while the bromadiolone and brodifacoum-based products achieved high efficacy.
AB  - Rattus norvegicus gotovo uvek živi u objektima namenjenim za gajenje domaćih životinja i kao sinanotropna vrsta prisutan je u čovekovoj najbližoj okolini.

U eksperimentima je korišćen ekološko prihvatljivi preparat na bazi natrijum-selenita (0,1%), preparat prirodnog porekla na bazi holekalciferola (0,75%) i antikoagulantni rodenticidi na bazi bromadiolona (0,005%) i brodifakuma (0,005%). Primenjeni preparati su formulisani u obliku granula, obloženog i zrnastog mamka. Ekološko prihvatljivi preparat na bazi natrijum-selenita je ispoljio efikasnost od 76,2% u prvoj godini istraživanja, u drugoj 70% i u trećoj godini 67,5%. Sintetisani preparati na bazi bromadiolona i brodifakuma pokazali su visoku efikasnost u sve tri godine ispitivanja za sve tri navedene formulacije.

AB  - The effects of general and special biosecurity measures to prevent introduction of infectious agents in a dairy farm or its spreading from farm were analyzed in details in this paper. Investigations were conducted on five different dairy farm production with different technology and capacity using a questionnaire method (Hristov and Stanković, 2009), as well as scrutinizing their positions in relation to possible sources bio-risks from the near and far away environment. Test results showed that there are serious shortcomings on all observed farms, regarding the possibility of introduction of infectious agents in the production herd, and its possible spread to the environment. Although all fenced and a position of the most of the farms mostly favourable, there are some serious threats to the herd health and farm production, regarding open space and lack of green belt, the uncontrolled presence of wild birds and rodents in facilities and even in feed storage, as well as contact of the employees with other cows not belonging to the farm.

AB  - The planned use of biosecurity measures, a high level of welfare and good manufacturing practices are critical for the health of cattle and pigs in intensive production. The required level of biosecurity on cattle and pig farms is the result of logical decisions and timely action taken in a specific epidemiological situation, recognizing the threats from the environment and the weak points in the production process. In this sense, the introduction of the principles of HACCP and sanitation protocols enable preventive of introduction and spread of infectious agents in the herd, while the farm biosecurity plan is the key factor in disease prevention, prevention of unwanted situations and performance improvement. According to results of cytogenetic blood testing of cattle and pigs on farms in Serbia, showed in this paper, a substantial percentage of cows have a change in the structure and number of chromosomes. Cytogenetic tests allow the detection of carriers of hereditary anomalies and may be indicators of environmental pollution, especially animal feed. For these reasons, our recommendation is that industrial-type farm, and the Centers for reproduction and artificial insemination, approaches using the results of cytogenetic testing and their involvement in biosecurity plans.
AB  - Planska primena biosigurnosnih mera, visok nivo dobrobiti i dobra proizvođačka praksa presudni su za zaštitu zdravlja goveda i svinja u intenzivnoj proizvodnji. Potreban nivo biosigurnosti na farmama goveda i svinja predstavlja rezultat logičnih rešenja i pravovremeno preduzetih aktivnosti u konkretnoj epidemiološkoj situaciji, sa prepoznavanjem pretnji iz okruženja i slabih tačaka u tehnološkom procesu proizvodnje. U tom smislu, uvođenjem principa HACCP-a i protokola sanitacije sprečava se unošenje i širenje infektivnih agenasa u zapatu, dok je plan biosigurnosti na farmi ključni u prevenciji bolesti, sprečavanju neželjenih situacija i unapređenju poslovanja. U ovom radu prikazan je deo rezultata citogenetičkih ispitivanja krvi goveda i svinja na farmama u Srbiji, prema kojima znatan procenat ispitivanih životinja poseduje promene u strukturi i broju hromozoma. Citogenetička ispitivanja omogućavaju otkrivanje nosilaca naslednih anomalija a mogu da budu pokazatelji zagađenja životne sredine, posebno hrane za životinje. Iz tih razloga, naša preporuka je da farme industrijskog tipa, kao i centri za reprodukciju i veštačko osemenjavanje, pristupe korišćenju rezultata citogenetičkih ispitivanja i njihovom uključivanju u planove biosigurnosti.

AB  - This paper gives a detailed analysis of the applied biosecurity measures in the production of boar sperm at a swine reproduction center. Biosecurity indicators (existence of a written biosecurity plan, isolation, introduction of newly acquired animals into the herd, herd health, assessment of the personnel attitude towards equipment, traffic control, attitude towards visitors, feeding and watering control, manure management, disposal of dead animal carcasses, attitude towards other animals, rodents and birds control, sanitation) were viewed and evaluated by rating scale: (5) - excellent, (4) - very good, (3) - good, (2) - sufficient, (1) - insufficient, there are resources for improvement (0) - insufficient, with no resources for improvement. Obtained data were analyzed in the SWOT process, taking into account all the strengths, weaknesses, threats and opportunities for improving the biosecurity level. The situation in the center is rated as very good, with an average rating of 4.15. However, one disadvantage is serious and related to the boar facilities isolation possibilities, taking into account their location and the presence of two types of male breeding animals (boars and bulls) in the same location. Newly acquired breeding animals are purchased from various sources, but with a rigorous regime of control and not at the same time.
AB  - U radu je detaljno analizirana primena biosigurnosnih mera u proizvodnji sperme nerastova u jednom centru za veštačko osemenjavanje svinja. Sagledani su i procenjeni svi indikatori biosigurnosti (postojanje pisanog plana biosigurnosti, izolacija, uvođenje novonabavljenih životinja u zapat, zdravstveni status zapata, ocena odnosa osoblja prema opremi, kontrola kretanja i prometa, odnos prema posetiocima, kontrola ishrane i vodosnabdevanja, izđubravanje, uklanjanje leševa uginulih životinja, odnos prema drugim životinjama na farmi, kontrola populacija glodara i ptica, sanitacija), i ocenjeni prema skali ocena: (5) - odličan, (4) - vrlo dobar, (3) - dobar, (2) - dovoljan, (1) - nedovoljan, ima resursa za poboljšanje, (0) nedovoljan, nema resursa za poboljšanje. U razmatranju rezultata primenjena je SWOT analiza i utvrđene prednosti, nedostaci, rizici i mogućnosti za podizanje nivoa biosigurnosti. Stanje u centru je ocenjeno kao vrlo dobro, uz prosečnu ocenu 4,15. Međutim, jedan nedostatak je veoma ozbiljan i odnosi se na mogućnost izolacije objekata, uzimajući u obzir njegovu lokaciju i prisustvo dve vrste muških priplodnih životinja (nerastova i bikova) na istoj lokaciji. Nove priplodne životinje se nabavljaju iz različitih izvora, ali uz rigorozan režim kontrole i ne u isto vreme. Svakako, izmeštanje objekata za držanje priplodnih nerastova na drugu bezbednu lokaciju predstavlja složen ali prioritetan zadatak, kojim bi se otklonile brojne pretnje po proizvodnju sperme.

AB  - Reproductive parameters: open day period, insemination index, time between calving, were monitoring on a total 12.400 dairy cow dairy cows with milk yield of 8500 liters in 305 days long lactation period. Reproductive disorders observed were abortions, lack of heat, ovarian cysts and ovarial inactivity longer than 60 days after calving and endometrirtis as well. The evaluations of health status of calves, pregnant heifers, and cows were performed during the same period. Most often problems affecting calves were diarrheas and respiratory diseases. Peripartal cows were frequently affected by puerperal paresis, ketosis and abosonmal displacement. Indigestions were present both in lactating and puerperal period. Disease of acropodium were present all a round year. Trhypophiton spp. Infection were seen sporadically in pregnant heifers and actinomycosis was found in older cows after several lactation. Increased production and improved health and reproductive status were achieved after introduction of herd management programme. Good health of pigs is qualification for good reproduction and profitable production. Pig health can be improved in aim to achieve higher production. Disease like neonatal scour, edema disease, esophagogastric ulcer, osteodiustrophia, actinobacilosis, atrophic rhinitis, dysentery and recent times proliferate eneropaties could be competent services. Especially critical periods are sowing, 24-48 hours, after sowing, and period 10-14 days after repulsion. By flexible cooperation of farm owners and veterinarians by appreciation of nowadays knowledge production is possible to improve and serve concept 'from stable to table'. In this concept veterinarians have significant role from economic and ecologic point of view. Biosecurity, welfare, good producers, practice, or hazard analysis, on critical points are very important issues in intensive pig production.

In this paper are given certain solutions and routine activities in protection against biological contamination as well as procedures attitude towards different sized herds health protection at home and abroad. Stuff conscience about needs to protect production in general active attitude to real threats and taken measures are key to success in biosecurity plans creation and application on every farm for itself.
AB  - Od reproduktivnih poremećaja ustanovljeni su pobačaji, anestrije, sitni jajnici, ciste, inaktivni jajnici duže od 60 dana postpartum i endometritisi. Uporedo je praćeno i zdravstveno stanje teladi, visoko-steonih junica i krava, dok je u puerperijumu praćeno zdravstveno stanje prvotelkinja i višetelkinja. Dijareja i oboljenja organa za disanje su bili najčešći zdravstveni problemi teladi koji su se ispoljili na kontrolisanim farmama. U puerperijumu kao najčešći zdravstveni problemi ispoljili su se puerperalna pareza, ketoza i dislokacije sirišta. Indigestije kao ozbiljan zdravstveni problem su se javile kod krava u periodu laktacije i puerperijuma. Bolesti akropodijuma (aseptični pododermatitis i panaricijum) pratile su krave veći deo godine. U sporadičnim slučajevima dijagnostikovana je trihoficija kod visoko steonih junica i aktinomikoza kod krava koje su imale veći broj laktacija. Uvođenjem menadžmenta kontrole zdravlja i produktivnosti stada (MKZPS), došlo je do značajnog poboljšanja zdravlja, reporodukcije, a takođe i do povećanja proizvodnje. Dobro zdravlje svinje je uslov dobre reprodukcije, odonosno rentabilne proizvodnje. Zdravlje svinja se može unaprediti u cilju postizanja što veće proizvodnje. Zdravlje zavisi od uslova držanja, nege, ishrane, kontrole zdravlja i zdravstvene zaštite. Bolesti kao što su neonatalni scour, edemska bolest, ezofagogastrični ulkus, osteodistrofije, aktinobaciloza, atrofični rinitis, dizenterija, a u novije vreme proliferativne enteropatije koje mogu ugroziti proizvodnju svinja u intenzivnom odgoju, moguće je primenom profilaktičkih, terapeutskih mera pojačanom kontrolom stručnih službi, držati pod kontrolom. Posebno osetljivi kritični periodi su: samo prašenje, prvih 24-48 sati posle prašenja, od 7-10 dana nakon prašenja i period 10-14 dana po odbijanju prasadi. Fleksibilnom saradnjom vlasnika farmi sa stručnim službama uz poštovanje i sprovođenje stručnih saznanja, te primenom niza biotehničkih mera stavljanjem akcenta na preveniranje bolesti svinja, a u cilju promocije dobrog zdravlja svinja moguće je unaprediti proizvodnju. Biosigurnost, dobrobit, dobra proizvođačka praksa i analiza rizika na kritičnim kontrolnim tačkama su veoma značajni elementi za intenzivnu proizvodnju svinja. Planska primena biosigurnosnih mera presudna je u zaštiti zdravlja svinja i uspeha proizvodnje. U dužem vremenskom periodu na velikim farmama mlečnih rasa krava, svinja i ovaca, praćeno je prisustvo bioloških zagađivača životne sredine (patogene bakterije), kao i hemijskih zagađivača životne sredine (teški metali) i njihov uticaj na dobrobit i zdravstveno stanje životinja. Posebnu opasnost za žive sisteme predstavljaju teški metali koji reagujući sa organskim molekulima menjaju njihovu strukturu i funkciju. U organizam teški metali prodiru preko organa za varenje, organa za disanje i kože. Rezultati naših višegodišnjih istraživanja ukazuju da postoji opasnost od kontaminacije stočne hrane teškim metalima i njihovog deponovanja u organizmu životinja, kao i negativnog delovanja na reproduktivnu sposobnost domaćih životinja. Toksičnost teških metala generalno vodi ka formiranju slobodnih radikala inhibirajući aktivnost enzima antioksidativne odbrane, kao i oksidaciju glutationa i stvaranju malon dialdehida (MDA) kao markera oksidativnog stresa. Njihova toksičnost potiče od tendencije da stvaraju kovalentne veze sa sulfhidrilnim grupama biomakromolekula ili istiskuju određene kofaktore čime inhibiraju aktivnost pojedinih enzima.

AB  - This paper shows results of calf welfare risk assessment at intensive breeding farms. Assessment has been conducted on the basis of housing conditions which can have negative influence on welfare of cattle, especially in calf category considering their needs. According to analysis results very good housing conditions were confirmed in open shed rearing stall (C) and closed type rearing stall without feeding yard (A), whilst in closed rearing stall with feeding yard (B) housing conditions were estimated as acceptable. Based on collected data about housing conditions, we have estimated that the least risk for calf welfare is at C farm, slightly higher at A farm and the highest at B farm. Data about housing conditions and analysis of potential welfare risk factors show possible causes for already present health and other problems with animals, which also can reappear in future. However for that reason, applying described methods can increase rearing conditions and increase production at cattle farms.
AB  - U ovom radu prikazani su rezultati procene rizika po dobrobit teladi na farmi sa intenzivnim načinom gajenja. Procena je izvršena na osnovu faktora vezanih za uslove smeštaja koji mogu da imaju negativan uticaj na dobrobit goveda u kategoriji teladi, uzimajući u obzir njihove životne potrebe. Prema rezultatima analize, vrlo dobri uslovi smeštaja teladi utvrđeni su u otvorenom objektu (C) i zatvorenom objektu bez ispusta (A), dok su u zatvorenom objektu sa ispustom (B) uslovi procenjeni kao dobri. Na osnovu dobijenih podataka o smeštajnim uslovima, procenjeno je da u objektu C postoji najmanji rizik po dobrobit teladi, nešto veći u objektu A, a najveći u objektu B. Podaci o smeštajnim uslovima i analiza potencijalnih rizika po dobrobit ukazuju na moguće uzroke već prisutnih zdravstvenih i drugih problema kod životinja, kao i na probleme koji mogu da se jave u budućnosti. Iz tog razloga, primena opisanih metoda može da doprinese poboljšanju uslova gajenja i proizvodnih rezultata na farmama goveda.

AB  - Clostridium perfringens is the most important cause of clostridial enertitic disease in calves. During one calendar year at one dairy farm we isolated Closridium perfringens type B from calves during suckling period. Purpose of our research was to find the most appropriate therapy for that particular farm. It has been found statistically significant defenses (p lt 0,01) between clinical cases in calves within first six months of the year (20) in comparison with the number of calves with symptoms of enterotoxemia in second half of the year (41). Also, statistically significant differences (p>0,01) were observed as far as season was concerned. In the autumn/winter season incidence 47 sick calves were observed in comparison with spring/summer season when 14 animals became sick. It has not been found statistical significant difference (p>0,05) among two groups as far as mortality was concerned. Average age of the animals with symptoms were 71,63 ± 8,21 days. Average age for fatal cases were 71,63 ± 8,21 days. Average duration of the therapy was 6 days.
AB  - Enterotoksemija uzrokovana sa Cl. perfringens je perakutno oboljenje sa čestim fatalnim ishodom. U ovom radu su izneti podaci o kretanju enterotoksemije teladi uzrokovane sa Cl.perfringens tip B na farmi visoko-mlečnih krava u toku jedne kalendarske godine. Statističkom analizom ustanovljeno je da postoji značajna razlika (p lt 0,01) između broja obolele teladi u prvih šest meseci (20) u odnosu na broj obolele teladi u drugih šest meseci (41). Takođe, ustanovljena je statistički značajna razlika (p lt 0,01) u broju obolele teladi u jesenje-zimskom periodu u odnosu na prolećno-letnji period. U jesenjem-zimskom periodu obolelo je 47 teladi dok je u prolećno-letnjem periodu obolelo 14 teladi. Analizom broja uginule teladi između posmatrana dva perioda vremena, nije ustanovljena statistički značajna razlika (p>0,05). Izračunavanjem deskriptivnih statističkih parametara obolele i uginule teladi ustanovili smo da je prosečna starost obolele teladi na ispitivanoj farmi bila 71,63 ± 8,21 dan, a prosečna starost uginule teladi bila je 77,25 ± 16,39. Ovo ukazuje da je terapija i lečenje obolele teladi trajalo prosečno oko šest dana. Koeficijent varijacije kod uginule teladi je skoro dva puta veći nego kod obolele, što ukazuje na veću varijabilnost vremena lečenja obolele teladi.

AB  - During the hottest summer months in our country, conditions for thermal stress development in cows are present, especially when values of temperature and air humidity increase simultaneously. When temperature rises, cow organism becomes less efficient, due to primary non-evaporative patterns of heat release (radiation, conduction, convection), relying mostly on evaporative cooling through sweating and gasping. High relative humidity impedes evaporative cooling, so cows do not use enough body heat to prevent body temperature increase during hot and humid conditions, which are very common during summers in Serbia. Increase of ambient temperature, temperature-humidity index and rectal temperature of the cows above critical values are accompanied by decrease of dry matter intake and milk production, making dairy production less remunerative. Modifications which include shade, increase of passive ventilation and additional usage of fans and sprinklers in stables increase body heat release, decrease body temperature and support dry matter intake. New technologies, which include tunnel system of ventilation, were studied in order to evaluate cooling efficiency. Selection of cows for heat tolerance is possible, and it must be emphasized that continual selection for productive traits improvement and neglect of heat tolerance leads to increased sensitivity to heat stress. Nutritive needs of dairy cows change during heat stress demanding modifications of meal composition in order to decrease dry matter content, increase of its nutritive value, to prevent nutritive oversteps and to maintain normal function of rumen. In the future, maintenance of dairy production during hot and humid climate conditions will demand improvement of possibility of cooling, continuous improvement of meal composition, as well as genetic advances which include selection for heat tolerance and identification of genetic traits responsible for heat tolerance. .
AB  - U našoj zemlji, u toku najtoplijih letnjih meseci, postoje uslovi za razvoj termalnog stresa kod krava, naročito kod istovremenog povećanja temperature i relativne vlažnosti. Zbog primarnih neevaporativnih načina odavanja toplote (radijacija, kondukcija, konvekcija), organizam krava postaje manje efikasan sa povećanjem ambijentne temperature i oslanja se u znatnoj meri na evaporativno rashlađivanje u obliku znojenja i dahtanja. Visoka relativna vlažnost ometa evaporativno rashlađivanje, tako da za vreme toplih i vlažnih uslova, čestih u Srbiji u letnjem periodu, mlečne krave ne troše telesnu toplotu u dovoljnoj meri, da bi se sprečilo podizanje telesne temperature. Povećanje temperature sredine, indeksa temperature i vlažnosti i rektalne temperature krava iznad kritičnih granica prati smanjenje unošenja suve materije i proizvodnje mleka, čime se smanjuje rentabilnost u proizvodnji mleka. Modifikacije koje uključuju hladovinu, povećanje intenziteta prirodne ventilacije i dopunsko korišćenje mehaničkih ventilatora i prskalica u stajama povećavaju odavanje telesne toplote, snižavaju telesnu temperaturu i pospešuju unošenje suve materije. Nove tehnologije koje uključuju tunelski sistem ventilaticije su proučavane radi procene efikasnosti rashlađivanja. Selekcija krava na toplotnu toleranciju je moguća, ali treba imati u vidu da kontinuirana selekcija na poboljšanje proizvodnih osobina, zbog zanemarivanja toplotne tolerancije, dovodi do porasta osetljivosti na toplotni stres. Nutritivne potrebe krava se menjaju tokom toplotnog stresa zbog čega su potrebne izmene u sastavu obroka u pravcu smanjenja unošenja suve materije, povećanja hranljive vrednosti obroka, sprečavanja nutritivnih prekoračenja i održavanja normalne funkcije rumena. Održanje proizvodnje krava u toku toplih i vlažnih klimatskih uslova zahtevaće u budućnosti unapređenje mogućnosti rashlađenja, kontinuirani napredak u sastavljanju obroka, kao i genetska poboljšanja koja uključuju selekciju na toplotnu toleranciju i identifikaciju genetskih osobina koje povećavaju toplotnu toleranciju. .
