AB  - The study aimed to determine the effect of different fixed factors (breed, region, calving year,
calving season, parity and lactation stage) on daily milk production (yield and content) of four
dairy cattle breeds under the heat stress conditions (THI≥72). The research was conducted
on a set of test-day records of four dairy cattle breeds (Simmental, Holstein-Friesian, Red
Holstein and Brown Swiss) reared in the Republic of Serbia (Region of Mačva, Podunavlje and
Šumadija). The statistical analysis included test-day records collected in the period from the
beginning of the year 2012 to the end of the year 2019. Based on the performed analysis, it
could be demonstrated that all the effects included in the statistical model (breed, region,
calving year, calving season, parity and lactation stage) statistically highly significant (p<0.001)
affected daily milk production (yield and content) of cows reared in the terms of the heat stress
conditions. The highest daily milk production was determined in the region of Podunavlje, and
by the Holstein-Friesian breed. Furthermore, dairy cows calved during the spring season, in the
third lactation and from the 61st to the 120th day of lactation, had the highest milk production
during the summer period in an environment characterised by heat stress. Also, daily milk yield
of cows in a heat stress environment decreased in the period from June to September. The
results obtained indicate different animals’ responses to heat stress concerning the animal’s
breed, rearing region, calving year, calving season, parity and lactation stage.

AB  - This study was carried out in order to investigate the natural occurrence of toxigenic fungi and levels of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in the maize stored immediately after harvesting in 2016 and used for animal feed in Serbia. A total of 22 maize samples were collected from four different districts across the country: City of Belgrade (nine samples), Šumadija (eight samples), Podunavlje (four samples) and Kolubara (one sample). Toxigenic fungi were identified according to the morphological characteristics whereas the mycotoxins contamination were detected using biochemistry enzyme-linked immuno-sorbent (ELISA) assay. The tested samples were mostly infected with Aspergillus, Fusarium and Penicillium spp., except that one sample originated from Kolubara was not contaminated with Aspergillus species. Fusarium graminearum was the most common species in the maize sample from Kolubara district (60%), F. verticillioides in the maize samples from Podunavlje (43.75%) and City of Belgrade (22.4%) districts, and Penicillium spp. in the maize samples from Šumadija district (26.38%). In the analysed maize samples the presence of Aspergillus species was low (0-1.78%). Mycotoxicological analysis revealed the presence of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in all the investigated samples, except that DON and AFB1 were not recorded in the samples from Podunavlje and Kolubara districts, respectively. The investigated samples were highly contaminated with ZEA, with incidence of 100% for the samples from Šumadija, Podunavlje and Kolubara districts and 88.89% for the samples from City of Belgrade district. In addition, the samples contamination with DON was 100% and 22.2% for the samples from Šumadija, Kolubara and City of Belgrade, districts, respectively. The highest number of AFB1 positive samples was found in Šumadija district (87.5%), while in the City of Belgrade and Podunavlje districts, 55.56% and 50% AFB1 positive samples were established, respectively. Generally, remarkable infection of all the tested samples with toxigenic fungal species from Aspergillus, Fusarium and Penicillium genera were recorded. In addition, high contamination with mycotoxins ZEA, DON and AFB1 were also recorded; nevertheless, only in one sample the level of DON exceeded the allowed legal limit (1750 μg kg-1 ) according to Regulation for unprocessed maize. Therefore, permanent mycological and mycotoxicological analyses of maize grain are necessary for risk assessment of fungal and mycotoxin contamination throughout the food chain.
AB  - Ispitivanja u ovom radu izvedena su s ciljem da se odredi prirodna pojava potencijalno toksigenih gljiva iz rodova Aspergillus, Fusarium i Penicillium i sadržaj mikotoksina zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u kukuruzu uskladištenom neposredno posle berbe u 2016. godini i korišćenom za ishranu životinja. Ukupno 22 uzoraka zrna kukuruza sakupljeni su iz četiri regiona u Srbiji: Beogradski (devet uzoraka), Šumadijski (osam uzoraka), Podunavski (četiri uzorka) i Kolubarski (jedan uzorak). Toksigene vrste gljiva su identifikovane na osnovu morfoloških osobina, a sadržaj mikotoksina određen je pomoću biohemijske, imunoadsorpcione enzimske metode (ELISA). Ispitivani uzorci kukuruza većinom su bili inficirani sa Aspergillus, Fusarium i Penicillium spp., izuzev što u uzorku iz Kolubarskog regiona nisu bile identifikovane Aspergillus vrste. Fusarium graminearum bila je najučestalija vrsta u uzorku kukuruza iz Kolubarskog regiona (60%), F. verticillioides u uzorcima iz Podunavskog (43,75%) i Beogradskog regiona (22,4%) i Penicillium spp. u uzorcima iz Šumadijskog regiona (26,38%). U ispitivanim uzorcima kukuruza zastupljenost Aspergillus vrsta bila je niska (0-1,78%). Mikotoksikološkim analizama ustanovljeno je prisustvo zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u svim ispitivanim uzorcima kukuruza, izuzev što DON nije detektovan u uzorcima iz Podunavskog a AFB1 u uzorku iz Kolubarskog regiona. Ispitivani uzorci su visoko kontaminirani sa ZEA, 100% uzoraka iz Šumadijskog, Podunavskog i Kolubarskog regiona i 88,89% uzoraka iz Beogradskog regiona. Isto tako, sa DON bilo je kontaminirano 100% uzoraka iz Šumadijskog i Kolubarskog regiona i 22,2% iz Beogradskog regiona. Najveći broj AFB1 pozitivnih uzoraka ustanovljen je u Šumadijskom regionu (87,5%), dok je u Beogradskom i Podunavskom regionu ustanovljeno 55,56% i 50% AFB1 pozitivnih uzoraka, respektivno. Uopšteno razmatrajući, u ovim analizama ustanovljena je visoka zastupljenost toksigenih vrsta u svim ispitivanim uzorcima kukuruza. Isto tako, ustanovljena je visoka kontaminiranost uzoraka sa mikotoksinima ZEA, DON i AFB1, iako je samo u jednom uzorku sadržaj DON premašio dozvoljeni limit (1750 μg kg-1 ) prema zakonskoj regulativi za neprerađeni kukuruz. Zbog toga, stalne mikološke i mikotoksikološke analize zrna kukuruza neophodne su radi ocene rizika od gljivične i mikotoksin kontaminacije u lancu ishrane.

AB  - The analysis included 433 daughters of 10 bulls, calving for the first time in the period from 2007 to 2014, on 6 dairy farms of the Agricultural Corporation Belgrade AD. Fixed factors included in the model were the effects of the farm, year of calving and calving season, and as a random factor the impact of the bull sire. The observed fertility properties on the basis of which breeding values were calculated were the number of days of gestation, the age at the first insemination, the service period duration and the calving interval. Bulls were ranked on the basis of these properties and using the Spearman correlation coefficient, the degree of agreement between the ranks was determined. According to the breeding values calculated by using the Best Linear Unbiased Prediction (BLUP) method, the sire 1517 was best ranked for the trait duration of service period (-34,94 days) and the calving interval (-36,14 days), relative to the average of daughters. The effects of the farm and year of calving showed no significance (p>0.05) except on the duration of the gestation. The effect of the calving season showed a very high significance (p lt 0.001) for the following properties: age at first insemination, duration of the service period and calving interval, as well as significance (p lt 0.05) for the property duration of the gestation. A statistically very significant degree of agreement between the service period and the calving interval of 0.99** (p  lt 0.01) was determined by the Spearman coefficient of correlation, while there was no significant difference between the other properties (p>0.05).

AB  - Good rearing conditions are the key factor for health and welfare of calves. Diarrhea, respiratory and navel infections are commonly referred to as the most common health problems in calves. The aim of this study was an observation of rearing conditions and the occurrence of the most common health problems in calves on small rural farms in Danube Region of Serbia. Data were colected from 30 farms by surveying the farmers. The questionary consisted of 75 questions pertaining to the following: general information on the farm, and on calving, nutrition, weaning, housing, hygiene of space for cows and calves, on calf diseases and diseases prevention measures. According to the answers, the average number of all categories of cattle at the fams is 18 heads. Calves are separated from their mothers immediately after birth at 67% farms. They receive colostrum up to two hours after birth at 47% of the farms and immediately after birth at 20% of the farms. Average age of calves at weaning is 13 weeks. Calves begin to use hay usually between the 1 st and 2 nd week of life, and a concentrated feed in 2 nd week. They are held in different types of pens. Farmers specified diarrhea and respiratory diseases as the most common health problems in calves. Rearing conditions at the farms often do not meet the recommendations and the breeders do not implement all of the necessary preventive measures. Corrections in this regard could contribute to better health of calves.
AB  - Dobri uslovi gajenja su ključni faktor za očuvanje zdravlja i dobrobit teladi. Kao najčešći zdravstveni problemi teladi obično se navode prolivi, infekcije disajnih puteva i infekcije pupka. Cilj ovog istraživanja bio je sagledavanje uslova gajenja i učestalost pojave najčešćih zdravstvenih problema kod teladi na malim seoskim farmama u Podunavskom regionu Srbije. Podaci su prikupljeni sa 30 farmi anketiranjem farmera. Anketa se sastojala od 75 pitanja koja su se odnosila na: opšte informacije o farmi, teljenje, ishranu teladi, odbijanje, smeštaj, higijenu prostora za smeštaj plotkinja i teladi, bolesti koje se javljaju kod teladi i mere preventive bolesti. Prema odgovorima, prosečan broj goveda svih kategorija na farmama je 18. Telad se na 67% farmi odmah po rođenju odvaja od majki. Dobijaju kolostrum 2 sata po rođenju na 47% farmi, a na 20% farmi odmah po rođenju. Prosečna starost teladi pri odbijanju je 13 nedelja. Telad počinje da koristi seno obično između 1. i 2. nedelje života, a koncentrat u 2. nedelji. Telad se drže u različitim tipovima bokseva. Farmeri su naveli proliv i respiratorne bolesti kao najčešće zdravstvene probleme kod teladi. Uslovi gajenja na farmama često nisu u skladu sa preporukama i odgajivači ne sprovode sve neophodne preventivne mere za sprečavanje pojave bolesti. Korekcije u ovom pogledu bi mogle doprineti boljem zdravstvenom stanju teladi.

AB  - Maize is the very important silage source in the world. Timely harvesting ensure high maize forage yield and quality. Therefore, the study focused on the effects of four harvesting times (starting at the 12 August every 7 days) on yield and qualitative parameters of forage green mass of maize hybrid ZP 677. The experiment was set in Vojvodina Province, Serbia, during the 2013 and 2014 growing seasons. Plant height, stem diameter, number of leaves per plant, ear percentage, forage yield, dry matter content and crude protein content were higher, while stem percentage was lower in 2014 with favorable climatic condition. Forage yield, crude protein content, ADF and NDF decreased, while dry matter content significantly increased with delay in harvesting. The maize hybrid should be harvested when the milk line is three-quarter of the way down the grain that is in the third decade of August.
AB  - Kukuruz je veoma važan izvor silaže u svetu. Pravovremenom žetvom kukuruza obezbeđuje se visok prinos i kvalitet krme za silažu. Stoga je istraživanje fokusirano na uticaj četiri datuma žetve (počev od 12. avgusta svakih sedam dana) na prinos i kvalitativne parametre silokrme hibrida kukuruza ZP 677. Eksperiment je postavljen u Vojvodini, u Srbiji, tokom 2013. i 2014. godine. Visina biljke, prečnik stabla, broj listova po biljci, udeo stabla, prinos krme, sadržaj suve materije i sadržaj sirovih proteina bili su veći, dok je udeo stabla bio manji u 2014. godini sa povoljnim klimatskim uslovima. Prinos krme, sadržaj sirovih proteina, ADF i NDF su se smanjivali, dok se sadržaj suve materije povećavao sa kašnjenjem u žetvi. Hibrid kukuruza za krmu treba sakupljati kada je mlečna linija tri četvrtine visine zrna što je u trećoj dekadi avgusta.
