AB  - The aim of this paper was to determine the level of cows behavioral welfare protection on farms with different rearing systems. Research of cows behavioral welfare protection was carried out on 5 farms (farms A, B, C, D, E) of various capacities with a total of 192 animals. The smallest farm was with 18 (farm B), and the biggest with 80 cows (farm A). On farm C were 22, D 27 and farm E 35 cows. Two farms (farms A and C) represented the free system of rearing inside open stables, while the three farms (farms B, D and E) have tied system of cows rearing in enclosed stables. The two farms have outlets (farms A and D), from which outlet on farm A is always available to animals, while the outlet on farm D is used only during the day. Cows were 3 to 5 years old with an average lactation between 4000 and 5000 liters/year. To assess behavior, rating scales from 0 to 5 (0 - unsatisfactory, there are no resources to improve, 1 - unsatisfactory, there are resources to improve, 2 - sufficient, 3 - good, 4 - very good, 5 - excellent) were used. The appraisal is comprised of nine complex behavioral systems such as: reactivity, ingestion, explorative behavior, movement, social behavior, body hygiene, territoriality, reproduction, and rest and sleep of animals. On farms with free rearing system of behavioral care benefit was evaluated as 'good' (Farm A 3.44, farm B 3.22). Insufficient protection of behavioral welfare was found on farms associated with the breeding system without outlet (farm B 1.56 and farm E 1.44). Cow's behavioral welfare of farm D with tied system of rearing and use of outlet was rated as scale score 'good' on the average.
AB  - Cilj ovog rada je utvrđivanje nivoa zaštite bihejvioralne dobrobiti na farmama krava sa različitim sistemom gajenja. Istraživanje zaštite bihejvioralne dobrobiti izvršeno je na 5 farmi (farme A, B, C, D, E) različitog kapaciteta sa ukupno 192 grla. U najmanjoj farmi bilo je 18 (farma B), a u najvećoj 80 krava (farma A). Na farmi C bilo je 22, farmi D 27 i farmi E 35 krava. Na dve farme (farme A i C) zastupljen je slobodan sistem držanja u otvorenim stajama, dok se na tri farme krave drže vezano u zatvorenim stajama. Na dve farme postoje ispusti (farme A i D), na jednoj farmi je stalno dostupan (farma A), dok se na drugoj koristi samo preko dana (farma D). Farme B, D i E imaju vezani način držanja krava i zatvoreni tip staje. Na farmi D se krave drže vezane, ali su preko dana u ispustu. Krave su stare između 3 i 5 godina, sa prosečnom laktacijom između 4000 i 5000 litara mleka. Za procenu bihejvioralnih sistema ponašanja korišćene su skale ocena od 0 do 5 (5 - odličan, 4 - vrlo dobar, 3 - dobar, 2 - dovoljan, 1 - nedovoljan ima resursa za poboljšanje, 0 nedovoljan nema resursa za poboljšanje). Procena je obuhvatila devet složenih bihejvioralnih sistema, i to: reaktivnost, ingestiju, eksplorativno ponašanje, kretanje, socijalno ponašanje, higijena tela, teritorijalnost, reprodukciju i bihejvioralni sistem odmora i sna životinja. Na farmama sa slobodnim sistemom gajenja zaštita bihejvioralne dobrobiti ocenjena je kao dobra (farma A 3,44, farma B 3,22). Nedovoljna zaštita bihejvioralne dobrobiti utvrđena je na farmama sa vezanim sistemom gajenja bez ispusta (farma B 1,56 i farma E 1,44). Skalom ocena dobar na donjoj granici ocenjena je bihejvioralna dobrobit na farmi D sa vezanim sistemom gajenja i ispustom.

AB  - A present state in a cattle production in our country has been analyzed in this paper, with a special emphasis being given to the state in Simmental breed, which makes, according to some estimates, about 80-85% of total cattle stock in Serbia. Cattle breeding in Serbia is characterized by an unfavorable situation, especially expressed in a negative trend in a number of cattle. This fact is extremely adverse in this period, when we need to gain the grounds for milk production quotas what seems to be the greatest problem of the EU countries as well. A production of beef meat over a last few years has been stagnating at a very low level, so that even the smallest export quotas have not been realized. As a small producer of beef meat, the most wanted product of cattle breeding, our country cannot consider itself as a serious bidder in any of the markets. Out of these reasons as a priority in agro politics of our country there is an imposed need for constant application and acknowledgment of new stimulative measures in cattle breeding with the aim of creating as greater a number of goods producers of milk and meat, especially beef meat for export, as possible. Possibilities for development of cattle breeding in Serbia do exist and are reflexed in available agricultural land, working force, farm buildings and processing capacities, as well as the experts and research workers. It is necessary to increase livestock, enlarge production, decrease a number of petty producers and engage thoroughly in organizing and directing of production for both domestic and export needs.
AB  - U radu su prikazani proizvodni rezultati populacije goveda simentalske rase u zemljama Evrope i kod nas. Ukazano je i na višedecenijski negativan trend prisutan u govedarstvu Srbije, koji se ogleda posebno preko izraženog negativnog trenda broja goveda. Ta činjenica posebno je nepovoljna u ovom periodu, kada se stiču osnove za buduće proizvodne kvote za mleko, koje su i najveći problem zemalja EU. Proizvodnja goveđeg mesa poslednjih nekoliko godina stagnira na vrlo niskom nivou. Kao mali proizvođač junećeg mesa, naša zemlja se ni na jednom tržištu ne može pojaviti kao ozbiljan ponuđač, jer ne zadovoljava istovremeno tri vrlo bitna faktora važna za proizvodnju i izvoz proizvoda, a to su kvalitet, kvantitet i kontinuitet proizvodnje. Iz tih razloga nameće se kao prioritet u agrarnoj politici naše zemlje, stalna primena i odobravanje novih podsticajnih mera u govedarstvu u cilju stvaranja što većeg broja robnih proizvođača mleka i mesa, posebno junećeg mesa namenjenog izvozu. Razvojne mogućnosti govedarstva Srbije postoje, i ogledaju se kroz raspoložive poljoprivredne površine, radnu snagu, farmske objekte i prerađivačke kapacitete, stručne i naučne radnike.

AB  - Certain reproductive and performance traits of first calving Simmental cows, as well as the demonstration of those traits depending on the participations of different proportions of Red Holstein-Friesian genes (HF), were investigated. The investigation included 176 first calving cows, divided according to percentage of HF genes, in 5 groups (0%, 12,5%, 25%, 37,5%, 50%). Statistical analysis of data was done by method of Least squares (LSMLMW, Harvey, 1989). The effect of age at first fertilization was highly significant variated between groups of first calving cows and the youngest was in the fifth group (the group with 50% of HF genes), which were fertilized at 520,8 days. The average age at first conception for alln examined groups was 536,7 days. Least squares results shown that different proportion of HF genes was not significant (P>0,05) body weight of calves. The least body weight of calves was in group of first calving cows with 50% HF genes. The duration of pregnancy was 283,3 days and between different groups were not significant (P>0,05). The biggest values of service period and lactation were in the fifth group. The average period of lactation was 321,32 days and the longest (348,5 days) were established in fifth group cows 50% IIF genes. The average milk yield was 4224,34 kg with 3,83% milk fat or 4116,6kg 4%FCM. Cows with 50% HF genes produced more milk compared to the cows in other groups. Established results have shown that with increasing proportion of HF genes service period between calving interval and duration of lactation were longer. Also, with increasing of proportion of HF genes the milk yield and yield milk fat were raised while percent of milk fat was lower.

AB  - The system of livestock breeding as well as influence of more important factors of genetic nature on milk yield of sheep and cattle populations on the territory of Stara Planina Mountain, more specific region of the town Pirot, is analyzed in this paper. Results of the investigation have demonstrated that existing system of production can not be regarded as satisfactory, but considering the potential, it is necessary to make a great effort in order to achieve improvement of livestock production. Milkiness of sheep and cattle in this region is within the limits for specific breed however, by improving the breeding system better results could be achieved. Positive and negative genetic correlation of observed milk traits in sheep and cattle, was determined. If we accept the fact that sheep and cow milk originating from this region has specific quality traits due to the specificity of the region, and therefore essential role in production of Dojkinci hard cheese - kachkaval of Pirot type, then results obtained in this way could be indicator of more efficient application of improvement programmes in order to increase the production of milk and cheese.

AB  - The effect of paragenetic factors on longevity traits was investigated in Simmental cows housed at the "Zlatiborski Suvati" farm. The effect of the lactation number, the calving season and the age at first insemination on longevity traits such as the age at culling, the length of productive life the total number of milking days and the utilization index was examined. The general average (m), according to the model, for the age at culling, the length of productive life, the total number of milking days and the utilization index was 3496.31 days, 2637.14 days, 2000.43 days and 72.42 % respectively. The effect of the total number of lactations on all the longevity traits was very highly significant (P lt 0.001), whereas the calving season statistically very significantly affected only the age at culling (P lt 0.01). The age at first insemination had a very highly significant effect on the age at culling and the cow utilization index (P lt 0.001).

AB  - The results of investigation of some non-genetic factors on fertility traits of cows in the Black Pied cattle population are presented. The cows are of European Black and White cattle which are genetically improved with Holsteins. In total, there were 319 cows with 845 calvings. The influence of calving order, year and season of calving on insemination index service period, duration of pregnancy, calving interval and weight of calves at birth were investigated. The influence of independent factors was done by Least square method (Harvey, 1987). It was estemeted by investigation that calving order had very significant effect on duration of pregnancy and the weight of calves at calving (P lt 0,01), significant on insemination index (P lt 0,05) while non-significant effects were on service period and between calvings interval (P>0,05). The expected values were estimated for duration of pregnancy and calve weight at birth at heifers (277.96 days and 36.53 kg). The year of calving had very significant effect on insemination index and weight of calves at birth (P lt 0,01), while on service period, duration of pregnancy and calvings interval influence was not significant (P>0,05). Rather different influence was of season of calving, Table 3, which was very significant on insenination index (P lt 0,01), significant on duration of pregnancy (P lt 0,05) and non-significant (P>0.05) on other investigated traits.

AB  - The effect of cow age at first insemination on longevity and lifetime production traits was examined in the Simmental cows housed at the "Zlatiborski Suvati" (Mt. Zlatibor Pastures) farm. The general linear model was used to calculate linear regression coefficients for the effect of age at first insemination on longevity traits including the age at culling, the length of productive life, the total number of milking days and the cow utilization index as well as on lifetime production traits being lifetime milk production, the milk fat content of the lifetime milk production, lifetime milk fat production, lifetime production of 4% fat-corrected milk and milk production per milking, productive and lifetime day. Based upon the calculated linear regression coefficients, the age at first insemination had a very high significant effect (P lt 0.+001) on the age at culling and the cow utilization index (bxy=1.386 and bxy=-0.020) and no significant influence (P>0.05) on other longevity traits. Cow age at first insemination had no significant effect (P>0.05) on the lifetime milk and milk fat production traits.

AB  - Based on results of performed investigations and analysis of existing conditions relating to technological process in production of kachkaval, we propose the following: To determine the causes of disturbed secretion in case of cows and sheep, investigate the mechanism of proteolytic activity and explain the origin (endogenous or exogenous); Goat milk should be delivered to dairies separately; control of temperature and relative humidity in departments for maturing and drying of cheese; introduction of whey and water separation; in that case, butter can be produced from separated cream. In order to successfully realize project it is also necessary to investigate location of the dairy in Dojkinci in relation to raw material status in different seasons of the year, and take certain measures for improvement of hygienic condition of milk throughout entire technological process: milking, delivering to dairies, storage, transport, etc.; obligatory introduction of basic routine milk analysis when delivered to dairies (volume, acidity, etc.); Introduction of technological log - diary for certain phases of production of kachkaval is also necessary. Finally, subsequent to standardization of entire technological process activities related to obtaining of brand name for such product with determined geographical origin are of great importance.

AB  - Certain reproductive and performance traits of Simmental cows, as well as the demonstration of those traits depending on the effect of age at first fertilization, were investigated. The investigation included 606 cows divided according to age at first fertilization, in 10 groups (one month difference among groups). Statistical analysis of data was done by method of Least squares (LSMLMW, Harvey, 1987), the model with fixed influence of factors on observed traits was applied. In regard to the demonstration of performance traits, the effect of age at first fertilization was most expressive in first lactation. The greatest negative deviation from the general average in milk yield and yield of milk fat, were established in first calving cows which were the youngest at fertilization-calving. The increase of age at first fertilization induced the less negative deviations from the general average. In the second and third lactation, deviation from the general average depending on the age at first fertilization, expressed the same trend, but within the limits of random deviations (PX),05).

AB  - The investigation was carried out on the sheep farm on the mountain Stara planina. The trial included two sheep genotypes: 1. Pirot pramenka sheep and 2. Improved Pirot sheep. In order to estimate necessary parameters the least squares method was used. The obtained results show that heritability of milk yield was 0.35 and 0.33, fat percent amounted to 0.49 and 0.44, while protein percent was 0.50 and 0.49 (in the 1st and 2nd genotype, respectively). Results on the genetic correlation between important parameters of milk showed that there were both, positive and negative correlations. Coefficient estimations of genetic correlations of certain traits varied from very weak to strong. Correlations between fat yield and milk yield were 0.87 and 0.88, but the coefficient between protein percent and fat yield was -0.01 and -0.04, in the 1st i.e. 2nd genotype, respectively. There are no significant differences between observed genotypes.
AB  - ispitivanje genetičkih parametara (heritabilnosti i genetičkih korelacija) osobina mlečnosti ovaca je bilo cilj rada. Ispitivanja su obavljena na jednoj farmi ovaca u regionu Stare planine, kod dva genotipa (pirotska pramenka i pirotska oplemenjena ovca). Heritabilnost varira u granicama srednjih vrednosti sa maksimumom kod sadržaja proteina. Ustanovljena je kako, pozitivna, tako i negativna genetička korelacija posmatranih osobina mlečnosti ovaca. Vrednosti koeficijenata se kreću od slabih do jakih, a nisu utvrđene značajne razlike između genotipova.

Ispitivanja su obavljena na jednoj farmi ovaca u regionu Stare planine, kod dva genotipa (pirotska pramenka i pirotska oplemenjena ovca). Heritabilnost varira u granicama srednjih vrednosti sa maksimumom kod sadržaja proteina. Ustanovljena je kako, pozitivna, tako i negativna genetička korelacija posmatranih osobina mlečnosti ovaca. Vrednosti koeficijenata se kreću od slabih do jakih, a nisu utvrđene značajne razlike između genotipova.",

AB  - The investigation of the Sjenica Pramenka sheep breed was performed on a privately owned farm during the three-year period. The average fertility was 122.06% and it increased with age (I lambing - 119.37%, II - 123.68%, III - 124.21%). The experiment with oestrus synchronising in the normal breeding season (August) and in the anoestrus period (January and April) was performed by using vaginal pesariums and PSMG. Depending on the season of the treatment, oestrus was confirmed in 96.00%, 85.71% and 94.00% cases, while 82.00%, 60.71% and 56.00% of sheep lambed. All lambed sheep had an increased twining percentage (44%, 29% and 25% in August, January and April, respectively).
AB  - Ispitivanje plodnosti sjeničkog soja pramenke obavljeno je na jednoj privatnoj farmi u trogodišnjem periodu. Prosečna plodnost iznosila je 122,06% i povećavala se sa starošću grla (I jagnjenje 119,37%, II - 123,68%, III - 124,21%). Prosečna jalovost ovaca iznosila je 4,83%. Takođe, realizovan je ogled sinhronizacije estrusa u normalnoj sezoni parenja (avgust mesec) i u sezoni anestrije (januar i april) primenom vaginalnih pesarija i PMSG-a. U zavisnosti od sezone tretiranja estrus je konstatovan u 96,00%, 85,71%, odnosno 94,00% slučajeva, a ojagnjilo se 82,00%, 60,71%, odnosno 56% ovaca. Sva ojagnjena grla imala su povećan procenat bližnjenja. Dobijeni rezultati se mogu oceniti zadovoljavajućim i ukazuju da je u boljim zapatima sjeničkog soja pramenke moguće dalje povećanje nivoa plodnosti.
