AB  - An analysis of the phenotypic exposure and variability of lifetime milk production and milk fat and the content of milk fat of lifetime milk production was performed in 241 cows of Simental race distributed in three breeding areas (Čačak n = 67, Zlatibor n = 123 and Rudno n = 51).
Descriptive statistical analysis found that the average lifetime milk production and milk fat in all three breeding areas was 16081 and 627.2 kg with a variability of about 40%. The average number of lactations during the productive life of cows was 3.73 and ranged from 4.31 in the area of Čačak to 3.45 in the Rudna area. The variability was high and on average it was about 35%, which resulted from a wide variation interval ranging from only 3 to 10 lactation per head. The average content of lifetime productions milk fat was 3.91%. The content of milk fat of lifetime milk production, unlike milk production of milk and milk fat, is more influenced by genetic factors, which is why it is characterized by a very low variability of only 2.30%.
AB  - Analiza fenotipske ispoljenosti i varijabilnosti životne proizvodnje mleka i mlečne masti i sadržaja mlečne masti životne proizvodnje mleka sprovedena je kod 241 krave simentalske rase raspoređenih na tri odgajivačka područja (Čačak n=67, Zlatibor n=123 i Rudno n=51).
Deskriptivnom statističkom analizom ustanovljeno je da je prosečna životna proizvodnja mleka i mlečne masti na sva tri odgajivačka područja iznosila 16081 i 627,2 kg sa varijabilnošću od oko 40%. Prosečan broj laktacija u toku produktivnog života krava iznosio je 3,73 i kretao se od 4,31 na području Čačka do 3,45 na području Rudna. Varijabilnost je bila visoka i u proseku je iznosila oko 35%, što je posledica širokog intervala varijacije koji se kretao od svega 3 pa do 10 laktacija po grlu. Prosečan sadržaj mlečne masti životne proizvodnje mleka iznosio je 3,91%. Sadržaj mlečne masti životne proizvodnje mleka, za razliku od životne proizvodnje mleka i mlečne masti,više je pod uticajem genetskih faktora zbog čega se odlikuje dosta niskom varijabilnošću od svega 2,30%.

AB  - Behavior, welfare and protection of cattle are an integral part of organic livestock breeding. Organic production considers animals being cultivated in accordance with their basic needs, supporting most of their normal forms of behavior (inborn and acquired), while respecting the basic principles of well-being and protection. Organic as an alternative to conventional production respects the importance of behavior, welfare and protection of animals and is therefore  in line with natural animals needs.
Being familiar and understanding the behavior of animals is of multiple importance for successful breeding of cattle regardless to applied production system (intensive, extensive or organic).
Animal welfare and protection is a complex biotechnological issue and contains an aspect of science (biology, veterinary medicine, agronomy)and aspects of ethics. The welfare implies the quality of life and harmonious relationship of animal with its environment; as such, it became present in conventional and unavoidable topic in organic production in livestock breeding.
AB  - Ponašanje, dobrobit i zaštita gajenih životinja predstavljaju integralni deo organskog stočarstva. U organskoj proizvodnji životinje se moraju uzgajati u skladu sa njihovim bazičnim potrebama, odnosno na način u kome će ispoljiti najveći deo njihovih normalnih oblika ponašanja (urođenih i stečenih) uz poštovanje osnovnih načela dobrobiti i zaštite. Uvažavajući značaj ponašanja, dobrobiti i zaštite životinja organska proizvodnja, kao alternativa konvencionalnoj, upravo je usklađena sa prirodnim potrebama životinja.
Poznavanje i razumevanje ponašanja životinja od višestrukog je značaja za uspešno gajenje domaćih životinja bez obzira o kom sistemu proizvodnje je reč (intenzivni, ekstenzivni ili organski). 
Dobrobit i zaštita životinja je jedno kompleksno biotehničko pitanje i u sebi sadrži kako aspekt nauke (biologije, veterine, agronomije), tako i aspekte etike. Dobrobit podrazumeva kvalitet života i harmoničan odnos životinje sa okruženjem te je kao takva postala aktuelna u konvencionalnoj i nezaobilazna tema u organskoj proizvodnji u stočarstvu.

AB  - In scientific literature, fertility is generally assessed through age at first conception, gestation length, length of service period, calving interval, and calf birth weight.
Determination of the effect of particular non-genetic factors on the above traits is a vital step in cattle breeding and reproduction. 
Length of calving interval is largely governed by the effect of non-genetic factors, viz. fixed effects generally including the effect of breeding region, season of birth, calving season, year of birth, calf sex and their interactions, and continuous or regression effects including age at first conception or age at calving. 
The effect of fixed and continuous non-genetic factors on length of calving period was analysed in 245 Simmental cows (907 calving interval) in three breeding regions, with the effect of season of birth as a fixed factor and cow age at first conception as a continuous factor being highly significant (P  lt  0.01), and that of season of calving being significant (P  lt  0.05). The effect of breeding region, year of birth, parity group or age and calf sex was statistically non-significant (P > 0.05).

AB  - The effect of paragenetic factors on 4% FCM yield in complete and standard lactations was studied in 241 Simmental cows.
Farm, lactation number, birth season, calving season, their interactions and age at first conception were evaluated for their effect on the trait. 
The mathematical and statistical analysis of the data obtained, i.e. least square means, standard error, analysis of variance and coefficient determination, were calculated using the General Linear Model procedure. The effects of farm, lactation group and year of birth on the trait were very highly significant (P lt 0.001). Birth season and calving season had no statistically significant effect (P> 0.05) on the production of 4% FCM, either in whole or in standard lactations. The interaction between birth season, calving season and year of birth was variable and ranged from insignificant to very significant.
Age at first conception produced a significant (P lt 0.05) and non-significant (P>0.05) effect on 4% FCM yield in complete and standard (bxy=0.693ns) lactations, respectively.

Sezona rođenja i telenja nije statistički značajno uticala (P>0.05) na proizvodnju 4%MKM kako u celim tako i standardnim laktacijama. Uticaj interakcije između sezone rođenja,, sezone telenja i godine rođenja bio je varjabilan, i kretao se od nesignifikantnog do vrlo značajnog. Uzrast pri prvoj oplodnji statistički značajno (P lt 0.05) je uticao na proizvodnju 4%MKM u celim laktacijama, dok njegov uticaj na proizvodnju 4%MKM u standardnim laktacijama nije bio signifikantan (P>0.05). Koeficijenta determinacije (R2) bio je vrlo visoko značajan (p lt 0.001) i kretao se od  0.623 kod proizvodnje 4%MKM u celim do 0.652 kod proizvodnje 4%MKM u standardnim laktacijama.",

AB  - This study was conducted to evaluate the phenotypic expression and variability of lifetime performance traits (lifetime yields of milk, fat and 4%FCM, milk fat content, milk yield per milking day, milk yield per day of productive life and milk yield per day of life) and the effect of systematic factors (breeding region, total lactation number, year of birth and season of birth) and age at first conception on the above traits in 2548 Simmental cows. The test Simmental cows achieved the following: lifetime yields of milk, fat and 4%FCM - 14604, 554.8 and 14157 kg, respectively, milk fat content of lifetime milk yield - 3.81%, milk yield per milking day - 12.79, milk yield per day of productive life - 9.31 and milk yield per day of life - 5.46 kg. The marked variability of the traits, along with a certain percent of high-producing cows, enables further success in their selection.
AB  - Ispitivanje fenotipske ispoljenosti i varijabilnosti osobina životne proizvodnje (životna proizvodnja mleka, mlečne masti i 4%MKM, sadržaj mlečne masti kao i proizvodnja mleka po muznom produktivnom i životnom danu) izvršeno je na uzorku od 2548 krava simentalske rase. Na analiziranom uzorku simentalskih krava ostvarena životna proizvodnja mleka, mlečne masti i 4%MKM iznosila je 14604, 554.8 i 14157 kg, sadržaj mlečne masti životne proizvodnje mleka 3.81%, dok je proizvodnja mleka po muznom, produktivnom i životnom danu iznosila 12.79, 9.31 i 5.46 kg. Izražena varijabilnost ovih osobina, sa izvesnim procentom visoko proizvodnih grla, omogućava dalji uspešan rad u njihovoj selekciji.
