AB  - The effect of interaction between the farm and calving season, as well as the farm and group of lactations on milk performance traits (milk yield, yield of milk fat, 4% fat corrected milk and milk fat content) was analyzed on sample of 2805 Simmental cows with total 9718 standard lactations, housed on dairy farm 'Zlatiborski suvati' on Zlatibor (578 cows and 1968 lactations), dairy farm of the Agricultural holding Dobričevo in Ćuprija (964 cows and 3237 lactations) and dairy animals housed on family farms/households in the region of Kotraža (1263 cows and 4513 lactations). The significance of the effect of interaction between the farm and calving season, as well as interaction between the farm and group of lactations on all milk performance traits was very high (P (lt) 0.001), which justified their inclusion into models for assessment of the breeding value of dairy cows. The share of variance of interactions in total variance of milk performance traits in standard lactations was low (below and around 4%), which clearly indicated even more systematic factors and their interactions which influence the total variability of observed traits of milk performance of cows in standard lactations.
AB  - Uticaj interakcije farme i sezone telenja kao i farme i grupe laktacija na osobine mlečnosti (proizvodnja mleka, mlečne masti, 4% mast-korigovanog mleka i sadržaj mlečne masti) analizirano je kod 2805 krava simentalske rase sa ukupno 9718 standardnih laktacija koje su bile smeštene na farmi muznih krava 'Zlatiborski suvati' na Zlatiboru (578 krava i 1968 laktacija), farmi muznih krava na Poljoprivrednom dobru Dobričevo u Ćupriji (964 krava i 3237 laktacija) i području Kotraže na individualnim gazdinstvima (1263 krava i 4513 laktacija). Značajnost uticaja interakcija farme i sezone telenja, kao i interakcije farme i grupe laktacija na sve osobine mlečnosti standardnih laktacija bila je vrlo visoka (P (lt) 0.001), što opravdava njihovo uključivanje u modele za ocenu priplodne vrednosti muznih krava. Udeo varijanse interakcija u ukupnoj varijansi osobina mlečnosti standardnih laktacija bio je nizak (ispod i oko 4%), što jasno ukazuje na još veliki broj sistematskih faktora i njihovih interakcija koji utiču na ukupnu varijabilnost posmatranih osobina mlečnosti krava u standardnim laktacijama.

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  - The paper gives the analysis on the state in population of Simmental cattle reared in Europe with a special review on the state in Simmental cattle in our country which makes about 80 % total cattle fund in Serbia, and is characterized by a negative trend in the number of cattle, as well as by a low average milk production per cow. The most important results obtained by both domestic and foreign authors by means of various methods of improving Simmental breed and its raising in different systems have been shown. The directions for improving Simmental cattle according to the productive directions have been analyzed. Possible methods of improving the Simmental cattle in our country have been pointed out, which should be in accordance with already existing genetic potential of each actual population, its purpose (registered breeding stock, production breeding stock), as well as with the market needs for cow milk, milk products and meat (primarily beef meat, for export). A special emphasis has been given to the importance of organizing the production of meat in the cow-calf system in which Simmental breed, following the model of many European countries, should have good performance also in our country, if the same production should be organized in deserted hilly and mountainous regions. In this way we could contribute to more significant increase in overall beef production, and to reactivate unused natural resources as well.

AB  - Body development and type are very important indices of production ability of cows, their capacity to consume sufficient quantity of food, produce technologically high quality milk, reduce the energy consumption in production of milk, remain in exploitation as long as possible and give more progeny. This research included 278 cows of Simmental breed selected into the category of bull dams on the territory of Republic of Serbia. By application of method of least squares following average values of exterior measures were obtained: height to withers 136,04 cm; carcass length 165,81 cm; breast depth 73,61 cm; breast girth 201,12 cm; body mass 695,29 kg. Regions influenced statistically highly significantly all investigated exterior traits (P (lt) 0,01). Year of measuring had no statistically significant effect (P>0,05) on body development of Simmental bull dams. Obtained values were considerably uniform without any greater oscillations. .
AB  - Telesna razvijenost i tip su veoma važni pokazatelji proizvodnih sposobnosti krava, njihovih mogućnosti da konzumiraju dovoljne količine hrane, daju tehnološki kvalitetno mleko, smanje utrošak energije u proizvodnji i što duže ostanu u proizvodnji i daju veći broj potomaka. Ovim istraživanjem je obuhvaćeno 278 krava simentalske rase odabrane u kategoriju bikovskih majki na području Republike Srbije. Primenom metoda najmanjih kvadrata dobijene su prosečne vrednosti eksterijernih mera: visina grebena 136,04 cm; dužina trupa 165,81 cm; dubina grudi 73,61 cm; obim grudi 201,12 cm; telesna masa 695,29 kg. Regioni su statistički vrlo značajno uticali na sve ispitivane eksterijerne osobine (P (lt) 0,01).

abstract = "Body development and type are very important indices of production ability of cows, their capacity to consume sufficient quantity of food, produce technologically high quality milk, reduce the energy consumption in production of milk, remain in exploitation as long as possible and give more progeny. This research included 278 cows of Simmental breed selected into the category of bull dams on the territory of Republic of Serbia. By application of method of least squares following average values of exterior measures were obtained: height to withers 136,04 cm; carcass length 165,81 cm; breast depth 73,61 cm; breast girth 201,12 cm; body mass 695,29 kg. Regions influenced statistically highly significantly all investigated exterior traits (P (lt) 0,01). Year of measuring had no statistically significant effect (P>0,05) on body development of Simmental bull dams. Obtained values were considerably uniform without any greater oscillations. ., Telesna razvijenost i tip su veoma važni pokazatelji proizvodnih sposobnosti krava, njihovih mogućnosti da konzumiraju dovoljne količine hrane, daju tehnološki kvalitetno mleko, smanje utrošak energije u proizvodnji i što duže ostanu u proizvodnji i daju veći broj potomaka. Ovim istraživanjem je obuhvaćeno 278 krava simentalske rase odabrane u kategoriju bikovskih majki na području Republike Srbije. Primenom metoda najmanjih kvadrata dobijene su prosečne vrednosti eksterijernih mera: visina grebena 136,04 cm; dužina trupa 165,81 cm; dubina grudi 73,61 cm; obim grudi 201,12 cm; telesna masa 695,29 kg. Regioni su statistički vrlo značajno uticali na sve ispitivane eksterijerne osobine (P (lt) 0,01). Godina merenja nije statistički značajno uticala (P>0,05) na telesnu razvijenost bikovskih majki simentalske rase. Dobijene vrednosti bile su dosta ujednačene bez nekih većih oscilacija. .",

AB  - The effect of systematic factors on production traits over complete lactations was investigated in 2,805 Simmental cows born in 1982 and onwards. The cows were housed at three farms in different areas: at the Zlatiborski Suvati dairy farm, Zlatibor, at the Dobricevo Agricultural Farm, Cuprija and at private farms in the region of Kotraze. The systematic factors (farm, calving season, lactation groups, group (year x season of birth), farm x calving season and farm x lactation group interactions) and age at first conception had statistically highly significant (P (lt) 0.001) effects on all complete lactation traits, with the exception of the effect of calving season on complete lactation duration (P (lt) 0.05) and milk-fat content (P>0.05). No statistically significant effect was produced by age at first conception on complete lactation duration and milk-fat content (P>0.05). Determination coefficients ranged from 0.100 in complete lactation duration to 0.361 in milk-fat content.
AB  - Ispitivanje uticaja sistematskih faktora na ispoljenost proizvodnih osobina celih laktacija obavljeno je kod 2805 krava simentalske rase rođenih od 1982. godine pa na dalje.

Sistematski faktori (farma, sezona telenja, grupe laktacija, grupa (godina x sezona rođenja), interakcije farma x sezona telenja i farma x grupe laktacija) i uzrast pri prvoj oplodnji statistički su vrlo visoko značajano (P (lt) 0.001) uticali na sve osobine punih laktacija, izuzimajući uticaj sezone telenja na trajanje punih laktacija (P (lt) 0.05) i sadržaj mlečne masti (P>0.05). Uzrast pri prvoj oplodnji nije statistički značajno uticao na trajanje celih laktacija i sadržaj mlečne masti u njima (P>0.05). Koeficijenti determinacije kretali su se od 0.100 kod trajanja celih laktacija do 0.361 kod sadržaja mlečne masti.

AB  - The examination was made on the effect of systematic factors (parturition group, calving season, birth type, calf gender, and birth type-calf gender interaction) and age at first conception on the expression of reproductive traits (gestation length, service period, fertility intensity and calf birth weight) in 143 Simmental cows. The overall mean (μ) for gestation length, service period, intercalving period and calf birth weight was 284.14 days, 153.82 days, 416.92 days and 35.40 kg, respectively. The parturition group effect on all fertility traits was highly significant (P (lt) 0.01). The calving season statistically significantly (P (lt) 0.05) affected the intercalving period and calf birth weight. Birth type induced very significantly longer gestation (P (lt) 0.01) and higher calf birth weight in singles (P (lt) 0.01) and significantly longer service period in twins (P (lt) 0.05). Calf gender had a very significant effect (P (lt) 0.01) only on calf birth weight, and the interaction between birth type and calf gender significantly affected gestation duration only (P (lt) 0.05). The regression effect of age at first conception on all fertility traits was not significant (P>0.05).

AB  - Research included 3.461 first calving Simmental cows in control, with lactations concluded within one year. All first calving cows were reared by private/individual farmers on the territory of the Republic of Serbia. Phenotypic correlations between following milk and fertility traits have been investigated: duration of lactation DL, milk yield MY, milk fat content MFC, milk fat yield MFY, yield of 4% FCM, age at first calving AFC and duration of service period DSP. Results of the investigation of phenotypic correlations are obtained using mixed models LSMLMW (Harvey 1990). This method enables optimal consideration of numerous effects on investigated traits (bull sires, region, calving season, and calving year). Phenotypic correlation of traits in cattle breeding relates to presence of mutual positive or negative covariance which is result of the effect of genetic and factors of the environment. Information on phenotypic correlations between milk and fertility traits can be of great importance in selection of cows, since it provides possibility to choose/select heads based on several traits at the same time.
AB  - Ekonomičnost i uspeh u stočarskoj proizvodnji najčešće zavise od više osobina. Iz tih razloga neophodno je vršiti takozvanu simultanu selekciju na nekoliko osobina. Fenotipska povezanost osobina u govedarstvu odnosi se na postojanje zajedničke pozitivne ili negativne kovarijanse, koja nastaje kao rezultat delovanja genetskih i faktora spoljne sredine. Ovim istraživanjem je obuhvaćena 3.461 kontrolisana prvotelka simentalske rase, sa laktacijama zaključenim u toku jedne godine. Sve prvotelke su se nalazile na imanjima individualnih poljoprivrednih proizvoĐača na području Republike Srbije. U radu su ispitane fenotipske korelacije između sledećih osobina mlečnosti i plodnosti: trajanje laktacije, prinos mleka, sadržaj mlečne masti, prinos mlečne masti, prinos 4% MKM, uzrast pri prvom telenju, trajanje servis perioda. Rezultati istraživanja fenotipskih korelacija dobijeni su korišćenjem mešovitih modela LSMLMW (Harvey, 1990). Ovaj metod omogućava optimalno sagledavanje brojnih uticaja na ispitivane osobine (bikova-očeva, odgajivačkog područja, sezone telenja, godina telenja).

Phenotypic correlation of traits in cattle breeding relates to presence of mutual positive or negative covariance which is result of the effect of genetic and factors of the environment. Information on phenotypic correlations between milk and fertility traits can be of great importance in selection of cows, since it provides possibility to choose/select heads based on several traits at the same time., Ekonomičnost i uspeh u stočarskoj proizvodnji najčešće zavise od više osobina. Iz tih razloga neophodno je vršiti takozvanu simultanu selekciju na nekoliko osobina. Fenotipska povezanost osobina u govedarstvu odnosi se na postojanje zajedničke pozitivne ili negativne kovarijanse, koja nastaje kao rezultat delovanja genetskih i faktora spoljne sredine. Ovim istraživanjem je obuhvaćena 3.461 kontrolisana prvotelka simentalske rase, sa laktacijama zaključenim u toku jedne godine. Sve prvotelke su se nalazile na imanjima individualnih poljoprivrednih proizvoĐača na području Republike Srbije. U radu su ispitane fenotipske korelacije između sledećih osobina mlečnosti i plodnosti: trajanje laktacije, prinos mleka, sadržaj mlečne masti, prinos mlečne masti, prinos 4% MKM, uzrast pri prvom telenju, trajanje servis perioda. Rezultati istraživanja fenotipskih korelacija dobijeni su korišćenjem mešovitih modela LSMLMW (Harvey, 1990). Ovaj metod omogućava optimalno sagledavanje brojnih uticaja na ispitivane osobine (bikova-očeva, odgajivačkog područja, sezone telenja, godina telenja).",

AB  - Investigation included 292 Simmental cows selected as bull-dams on the territory of the Republic of Serbia in year 2002. For all investigated traits main variation-statistical parameters were calculated: arithmetic mean value, standard deviation, variation coefficients, standard error and variation interval. Average values of evaluation of the type of Simmental bull-dams were following: for type (frame) 7,89, muscle development 7,78, form (appearance) 7,79 and for udder 7,64. Linear evaluation values were above the average determined for Simmental population under control, which justifies the conclusion that bull-dams represent the elite heads of main herd. Visual evaluation and recognition of milk characteristics of cows are preliminary indicators of milk production, and partially also of longevity and reproductive ability of head of cattle, which is very important from the aspect of economical efficiency of milk production.

AB  - One of the important factors of successful milk production is group of secondary traits: health, longevity, type and milking traits. These traits have become increasingly significant. In order for productive life of cows used in production of milk to be as long and as successful as possible, special attention must be directed to traits of body type and constitution. In selection of cows into the category of bull dams all heads are measured - exterior traits, and evaluated linearly for traits of type or body frame, body muscular characteristics/muscularity, form (appearance) and udder according to Regulation on method of evaluation of traits of breeding livestock (Official journal of RS, No. 21,1996). The effects of rearing region and year of measuring, i.e. evaluating were analyzed in detail using the Least Squares Method (Harvey 1987). Average values of linear evaluations of investigated heads obtained by method of Least Squares were: body frame 7,85; muscularity 7,74; form 7,66; udder 7,62. The effect of region on linear evaluation was highly significant (P (lt) 0,01). Evaluation year also influenced highly significantly (P (lt) 0,01) obtained evaluation result for form, significantly (P (lt) 0,05) obtained evaluation result for body frame and muscularity, but no effect was established on evaluation result for udder.

AB  - Body development and production capacity in dairy production are in relation. However, body development, i.e. exterior of cows doesn’t define its functionality which is manifested in production of milk. Therefore, the capacity of cow to produce milk can only be determined more precisely by direct measuring of the production. Visual evaluation of body development and way to recognize the characteristics of dairy cows are initial parameters of milk traits, partially also longevity, as well as reproductive traits of the head of cattle, which is important from many aspects of the economical efficiency in dairy production. Exterior measures taken when cows were selected to be included in herd of bull dams, and which are also subject of this research, are following: height of withers, carcass length, breast depth, breast girth, body weight. For all investigated traits basic variation-statistical parameters were calculated: arithmetic mean value, standard deviation, coefficients of variation, standard error, variation interval. Average values of exterior measures obtained in this research were following: height to withers 136.29 cm, carcass length 165.50 cm, breast depth 72.97 cm, breast girth 200.07 cm, body weight 686.27 kg. Based on presented data it can be concluded that traits of body development of Simmental bull dams are above the average values determined for controlled population, which further justifies our conclusion that bull dams are "top" heads of cattle of the main herd.

AB  - Cattle reproduction is most significant production phase because in this phase heads of cattle for maintaining of the herd are provided, as well as for dairy production and fattening - production of meat. The effect of year and season of calving on age at first conception, duration of pregnancy duration of service period, interval between calving, etc. is investigated in the paper.

AB  - Investigation included bull dams of Simmental breed selected on farms of agricultural producers on the territory of the Republic of Serbia. Method of Least Squares - LSMLMW (Harvey 1987) was used for analysis of the effect of region and order of lactation on reproductive traits. Obtained results indicate the justification for investigation of paragenetic factors, since the knowledge of their effect can contribute to more objective evaluation of random effects. Regions had highly significant effect (P (lt) 0,01) on age at first conception, duration of service period and interval between calvings whereas no significant effect on duration of pregnancy was registered (p>0.05). The effect of region of breeding many factors are included and most important one is nutrition. Order of lactation as second factor investigated in this research had no effect on any of the fertility traits (p>0.05). General average of mean values of least squares for fertility was: for age at first conception 517.61 days, duration of pregnancy 285.51 days, duration of service period 108.98 days, interval between calving 395.34 days.

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  - 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  - Stara planina spada u red najpoznatijih stočarskih regiona Srbije. Tokom istorije ovom planinom su prolazila nebrojena stada ovaca i gajilo se mnogo goveda. Zahvaljujući toj činjenici, koja je rezultat izvanrednih prirodnih uslova za bavljenje stočarstvom, javili su se i postali poznati širom sveta proizvodi kao: pirotski kačkavalj, pirotsko jagnje i pirotski ćilim. Posle vekovima uspešnog stočarstva Stare planine, poslednih decenija XX veka krenuo je ne zadrživ proces stagnacije, što je praćeno ne samo smanjenjem proizvodnje i redukcijom broja seoskog stanovništa već i odumiranjem pojedinih sela. Da paradoks bude veći tražnja za proizvodima sa ovog područja pre svega kačkavalja ne prestaje i biva sve veća. Promene u pogledu privrednog razvoja naše zemlje koje su u toku osvetlile su zaboravljenu Staru planinu i pirotski kačkavalj, jer se shvatilo da Srbija može ponuditi svetskom tržištu baš te, već poznate specijalitete sa prirodno ne zagađenih područja. Da bi se to i desilo bilo je neophodno započeti projekat koji će na naučnim osnovama omogućiti sagledavanje potencijala i pokazati pravi put za aktiviranje resursa. Ovim projektom se planiraju sledeće najvažnije aktivnosti: -Utvrđivanje mogućnosti proizvodnje stočne hrane i način ishrane ovaca i goveda i predlog mera za njihovo poboljšanje. -Ispitivanje proizvodnog potencijala populacija ovaca i goveda i predlog mera za unapređenje proizvodnje mleka. -Snimanje tradicionalne tehnologije proizvodnje kačkavalja i standardizacija svih procesa od prijema mleka do zrenja sira. -Na osnovu standardizacije proizvodnje kačkavalja i ispitivanja svih važnih osobina dobiće se robna marka i prepoznatljive karakteristike novog proizvoda koji će biti uveden u sistem za dobijanje oznake geografskog porekla.

Ovim projektom se planiraju sledeće najvažnije aktivnosti: -Utvrđivanje mogućnosti proizvodnje stočne hrane i način ishrane ovaca i goveda i predlog mera za njihovo poboljšanje. -Ispitivanje proizvodnog potencijala populacija ovaca i goveda i predlog mera za unapređenje proizvodnje mleka. -Snimanje tradicionalne tehnologije proizvodnje kačkavalja i standardizacija svih procesa od prijema mleka do zrenja sira. -Na osnovu standardizacije proizvodnje kačkavalja i ispitivanja svih važnih osobina dobiće se robna marka i prepoznatljive karakteristike novog proizvoda koji će biti uveden u sistem za dobijanje oznake geografskog porekla.",

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, 1989), the model with fixed influence of factors on observed traits was applied. Established results have shown that the age of head of cattle at first fertilization had highly significant effect (P (lt) 0,01) on the occurrence of deviation from the general average in the first service period and also on the weight of calves at first calving. At the second and third calving, the deviations from the general average in investigated reproductive traits were within the limits of random. 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 (P>0,05).

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.
