AB  - The study of the production capacities of cattleaimed at increase of the capacity of cattle to produce milk, milk fat and calves, greatly depends on pehotypic and genetic variability, heritability and correlation between preferable traits, as well as level of production in the population. Objective of the study was to calculate the variability, phenotypic and genetic correlation of milk and type traits by applying the method of linear scoring of cows in the nucleus herd of Holstein-Friesian bull dams and also to determine their significance in cattle selection. For all studied traits, main variation-statistical parameters were calculated by applying method of least squares: arithmetic mean, standard deviation, variation coefficient, standard error and variation interval. Negative phenotypic correlations between production of milk and type traits ranged from -0.12 (rear leg set, side view) to -0.01 (rump height and body depth) and positive from 0.03 (rear teat placement) to 0.23 (suspensory ligament). Phenotypic correlations between milk fat percentage and type traits varied in the range from -0.08 (fore teat placement) to 0.14 (rump height). Negative genetic correlations between milk production and type traits ranged from -0.11 (rear udder height) to -0.01 (rump width and dairy form), and positive from 0.03 (rear legs set, rear view) to 0.23 (suspensory ligament). Genetic correlations between the percentage of milk fat and type traits ranged from -0.15 (pelvic position) to 0.18 (rump height). Information about phenotypic and genetic correlations between milk and type traits can be of multiple significance in cow selection since it offers possibility to select heads of cattle for multiple traits at the same time.

Cilj ovih istraživanja bio je da se u nukleus zapatu bikovskih majki holštajn frizijske rase primenom linearnog metoda ocenjivanja krava izračuna varijabilnost, fenotipska i genetska povezanost osobina mlečnosti i tipa, i njihov značaj u selekciji goveda. Za sve ispitivane osobine primenom metoda najmanjih kvadrata izračunati su osnovni varijaciono-statistički parametri: aritmetička sredina, standardna devijacija, koeficijenti varijacije, standardna greška i interval varijacije. Negativne fenotipske korelacije između proizvodnje mleka i osobina tipa kretale su se u intervalu od -0.12 (položaj zadnjih nogu sa strane) do -0.01 (visina krsta i dubina tela), a pozitivne od 0.03 (položaj zadnjih sisa) do 0.23 (centralni ligament). Fenotipske korealacije između procenta mlečne masti i osobina tipa kretale su se u intervalu od -0.08 (pozicija prednjih sisa) do 0.14 (visina krsta). Negativne genetske korelacije između proizvodnje mleka i osobina tipa varirale su u razmaku od -0.11 (visina zadnjeg vimena) do -0.01 (širina karlice i mlečne karakteristike), a pozitivne od 0.03 (položaj zadnjih nogu otpozadi) do 0.23 (centralni ligament). Genetske korealacije između procenta mlečne masti i osobina tipa kretale su se u intervalu od -0.15 (položaj karlice) do 0.18 (visina krsta). Postojanje informacija o fenotipskim i genetskim korelacijama između osobina mlečnosti i tipa, može imati višestruki značaj u selekciji krava, jer pruža mogućnost odabira grla na više osobina istovremeno.

AB  - Body condition of high yielding Holstein-Friesian dairy cows changes during the production cycle. It represents important indicator of achieved level of nutrition and degree of nourishment. BCS is a functional method, and integral part of the strategy and basis of corrective activities in farm management. BCS of cows in all phases of production cycle is important indicator of applied nutrition, but also of the technological process sin general. The amount of body reserves in form of fat tissue cow has before calving as huge impact on incidence of potential post-calving problems, production of milk, reproductive efficiency and health condition. Very often animals are culled from the herds prematurely, which shortenes the life exploitation of cows. Longevity is the ability to survice in certain production conditions. Life expectancy is from the economical aspect the most important functional trait of high yielding cows and represents necessary condition for sustainability of milk production over longer period. Average BCS of culled cows for the first stage of lactation was 3,35 (2,41-4,37) for the second stage of lactation 3,50 (2,59-4,59), for the third 2,22 (1,44-2,91) and the fourth 2,36 (1,37- 3,37). Variation coefficient (Cv) ranged from 12,59 to 16,82. Average age of culled cows was 2037,07 days or 5,58 years with variation interval of 742,00 to 5430,00 days. Age at culling showed high variability (Cv=45,69). Number of culled cows (n=34 or 32.69%) was the highest at the age of over 7 years (7,10-14,88). The same cows showed the highest variability in regard to longevity (Cv=17,97).

Koeficijent varijacije (Cv) kretao se od 12,59 do 16,82. Realizovane vrednosti ukazuju da je kod distribucije prosečnih BCS krava u prvoj fazi proizvodnog ciklusa od ukupnog broja krava koji čini 107 grla najviše (n=23 ili 21,50 %) bilo u intervalu BCS od 2,76 do 3,00.

Ispod tog intervala BCS bilo je 5 grla ili 4,81%, a iznad 80 grlo ili 76,92%. U ovoj fazi proizvodnje u intervalu BCS od 3,76 do 4,75 bilo 31 krave ili 29,81%. U trećoj fazi od 84 ocenjene krave najviše grla (n=25 ili 29,76%) bilo je u intervalu BCS od 2,00 do 2,25. Ispod navedenog nivoa BCS bilo je 19 grla ili 22,62%, a iznad 40 krava ili 47,62%. U četvrtoj fazi od ukupno 66 ocenjena grla najviše krava (n=17 ili 25,76%) bilo je u intervalu BCS od 2,26 do 2,50. Ispod tog intervala BCS bilo je 26 grla ili 39,39%, a iznad 23 krave ili 34,85%. U celini posmatrano rezultati su značajno su odstupali od preporučenih vrednosti za BCS. Prosečna starost krava kod izlučenja iznosila je 2037,07 dana ili 5,58 godina sa intervalom varijacije od 742,00 do 5430,00 dana, odnosno, od 2,04 do 14,88 godina. Starost kod izlučenja pokazala je visoku varijabilnost (Cv=45,69). Broj izlučenih krava (n=34 ili 32.69%) bio je najveći u starosti preko 7 godina (7,10-14,88). Iste krave pokazale su i najveću varijabilnost u pogledu dugovečnosti (Cv=17,97). Najviši prosečan nivo BCS u prvoj i drugoj fazi proizvodnog ciklusa imale su krave koje su bile stare na izlučenju od 4,1 do 5 godina (3,49; 3,66), u trećoj fazi krave koje su bile stare na izlučenju od manje od 3 godine (2,26) i u četvrtoj fazi krave koje su bile stare 5,1 do 6 godina (2,55).

AB  - Evaluation of conformation and fat cover of beef carcasses has great importance in modern systems of carcass quality evaluation. In this way, adequate price is achieved for every classified carcass side according to market demand. In this paper, the effect of experimental crossing of Domestic Simmental breed with Charolais and Limousine breed (N=96) on conformation and fat cover was investigated. Evaluation was carried out on the whole carcass and partially for certain parts of carcass according to special evaluation pattern/form (1-5). In regard to evaluation of carcass conformation, statistically significant differences (p (lt) 0,01) were established between crosses and Domestic Simmental breed. Crosses with Charolais achieved the highest score for conformation (3,94), the highest score for round conformation (3,77) and shoulder (4,06). Considerably more fat tissue on outside of the carcass was determined in Domestic Simmental breed (3,44) compared to crosses with Charolais (3,27). Presence of fat in pelvic cavity was more expressed in Charolais (3,34) and Limousine crosses (3,28), with better score for covering of kidneys (3,50 and 3,53) compared to Domestic breed (3,17).

U ovom radu ispitivan je uticaj eksperimentalnog ukrštanja domaće simentalske rase sa šarole i limuzin rasom (N=96) na konformaciju i prekrivenost junećih trupova lojem. Ispitivanje je obuhvatilo ocenu pomenutih osobina na celim trupovima kao i parcijalno na određenim delovima trupova a prema odgovarajućoj linearnoj skali ocene (1-5). U odnosu na ocenu konformacije trupova utvrđene su statistički značajne razlike (p (lt) 0,01) između meleza i domaće simentalske rase. Melezi Šarolea postigli su najbolju ocenu konformacije trupova (3,94), konformacije buta (3,77) i plećki (4,06). Značajno više masnog tkiva na spoljašnjem delu trupa utvrđeno je kod domaće simentalske rase.(3,44) u poređenju sa melezima Šarolea (3,27). Prisustvo masti u karličnoj šupljini bilo je izraženije kod Šarole (3,34) i Limuzin meleza (3,28), sa boljom ocenom prekrivenosti bubrega (3,50 and 3,53) u odnosu na domaću simentalsku rasu (3,17).

U odnosu na ocenu konformacije trupova utvrđene su statistički značajne razlike (p (lt) 0,01) između meleza i domaće simentalske rase. Melezi Šarolea postigli su najbolju ocenu konformacije trupova (3,94), konformacije buta (3,77) i plećki (4,06). Značajno više masnog tkiva na spoljašnjem delu trupa utvrđeno je kod domaće simentalske rase.(3,44) u poređenju sa melezima Šarolea (3,27). Prisustvo masti u karličnoj šupljini bilo je izraženije kod Šarole (3,34) i Limuzin meleza (3,28), sa boljom ocenom prekrivenosti bubrega (3,50 and 3,53) u odnosu na domaću simentalsku rasu (3,17).",

AB  - This paper presents the results of a study on the effects of crossing domestic Simmental with French fattening breeds, Charolais and Limousin, on carcass and meat quality. The quality of carcasses from domestic Simmental cattle and its crosses (N = 30) was analysed by total dissection for the proportion of retail cuts in the carcass and carcass tissues. Traits of meat sensory and technological quality were investigated using standard methods on a total of 96 carcasses. The results showed that crossing did not have a significant effect on the proportion of retail cuts except the proportion of tenderloin steak, which was significantly higher (P (lt) 0.01) in crosses with Charolais (1.87%) and Limousin (1.85%) compared to the domestic Simmental breed (1.38%). However, highly significant differences (P (lt) 0.01) were established for the level of tissue content in the whole carcass. The highest proportion of muscle tissue (81.5%) was determined in carcasses obtained from Limousin crosses, whereas the highest content of bone (16.45%) and fat tissue (5.26%) was recorded in carcasses of domestic Simmentals. Crossing had positive effects on the sensory quality of meat except for marbling, which scored very low in the crosses. In general, comparison of the parameters of sensory and technological quality of meat from the studied genotypes showed that the most desirable quality properties of the meat were obtained from crosses of domestic Simmental and Limousin breeds.

AB  - Group of secondary traits such as health, longevity, type and milkability represents some of very important factors for successful milk production. These traits have been given great importance in recent years. In order to realize productive life of dairy cows as long and successful as possible, special attention should be directed to traits of type and body constitution. Objective of the research was to establish heritability coefficients for 14 type traits of first calving Black and White cows, effect of genetic and paragenetic factors (bull sires, farm, year and season of calving, age at scoring and share of Holstein-Friesian [HF] genes) on type traits, so that these scores could be included in calculation of breeding value of the animal. Also, average values of milk traits have been established: milk yield and yield of 4% fat corrected milk (FCM), content and quantity of milk fat. Evaluation was performed on a sample of 2 976 first calving Black and White cows. Evaluated cows were reared on 7 farms of the Agricultural Corporation Belgrade in Serbia. Analysis of discontinuous and continuous influences was done using the method of least squares. Investigation indicated that the value of linear type evaluation should be included in the total evaluation of the breeding value and in this way complete insight into genetic supremacy, especially of breeding bulls, would be obtained. Use of bull semen of proven supremacy in transmission of genes desirable from the aspect of body constitution, in the process of artificial insemination, would lead faster to production herds with animals which are uniform in type, of good conformation and longevity, which is of special significance in conditions of intensive rearing of dairy cattle.

AB  - Condition of animals is manifested through level of achieved nourishment. Body condition score (BCS) is a precise method of determination of reserves of deposited energy in form of subcutaneous fat tissue. Adequate body reserves are necessary requirement for maximal increase of milk production in the period of early lactation. Based on BCS we can precisely determine the number of cows which are bellow weight (excessively thin) or over weight (excessively fat). Body condition changes during lactation. Cows in early lactation are in the negative energy balance (NEB). Changes of the body condition should be over at the end of lactation. Objective is to have cows in optimal body condition during all production phases. Object of research was body condition of high yielding cows during production cycle. Realized sample size was 363 cows of Holstein-Friesian breed. Average BCS value of cows in dry period was 3.39 (2.37-4.41), at calving 3.56 (2.55-4.63), at lactation peak 2.30 (1.35-3.16) and in the mid lactation 2.50 (1.35-3.43). In dry period, most of cows (n=100 or 27.55%) ranged in BCS from 3.26 to 3.50. During dry period increase of body condition scores of cows occurred. At calving, most of heads (n=99 or 27.50%) ranged in their BCS from 3.51 to 3.75. During period of early lactation there was a significant decrease of the body condition of cows. At the peak of lactation a slight increase of body condition was recorded. At the peak of lactation, most cows (n=125 or 36.76%) ranged in BCS from 2.26 to 2.50. In the mid-lactation period, slight increase of body condition of cows occurred. During this period, most cows (n=88 or 27.32%) ranged in their BCS from 2.51 to 2.75. In general, realized average BCS results according to production phases deviated statistically significantly from target values.

AB  - Investigation of the production capacity of cattle for the purpose of increase of milk and milk fat production, as well as number of calves, greatly depends on phenotypic and genetic variability, heritability and correlation between desired traits, and on production level in the population. This research included 3.461 first calving cows of Simmental breed under control and reared on farms of individual agricultural producers on the territory of Republic of Serbia. Genetic correlations were calculated using equation of mixed model which included the effect of bull-sire, breeding region, year and season of calving: Yijklm = μ + Bi + Rj + Gk + Sl + eijklm. Coefficients of genetic correlation between service period and milk traits were following: duration of lactation 0,239, milk yield 0,089, percentage of milk fat 0,095, quantity of milk fat 0,105 and yield of 4%FCM 0,099. Correlation between service period and age at calving was 0,535. Genetic correlation between age at calving and milk traits was following: duration of lactation 0,245, production of milk 0,003, percentage of milk fat 0,531, quantity of milk fat 0,082 and production of 4%FCM 0,050.
AB  - Ispitivanje proizvodnih kapaciteta goveda u cilju povećanja proizvodnje mleka, mlečne masti i broja teladi, u velikoj meri zavisi od fenotipske i genetske varijabilnosti, heritabiliteta i povezanosti poželjnih osobina, kao i nivoa proizvodnje u populaciji. Ovim istraživanjem je obuhvaćena 3.461 kontrolisana prvotelka simentalske rase na imanjima individualnih poljoprivrednih proizvođača na području Republike Srbije. Genetske korelacije izračunate su jednačinom mešovitog modela koja uključuje uticaj bika-oca, odgajivačkog područja odnosno regiona, godine i sezone teljenja: Yijklm = μ + Bi + Rj + Gk + Sl + eijklm. Koeficijenti genetske povezanosti između servis perioda i osobina mlečnosti su sledeći: trajanje laktacije 0,239, prinos mleka 0,089, procenat mlečne masti 0,095, količina mlečne masti 0,105 i prinos 4%MKM 0,099. Povezanost servis perioda i uzrasta pri telenju iznosila je 0,535.

abstract = "Investigation of the production capacity of cattle for the purpose of increase of milk and milk fat production, as well as number of calves, greatly depends on phenotypic and genetic variability, heritability and correlation between desired traits, and on production level in the population. This research included 3.461 first calving cows of Simmental breed under control and reared on farms of individual agricultural producers on the territory of Republic of Serbia. Genetic correlations were calculated using equation of mixed model which included the effect of bull-sire, breeding region, year and season of calving: Yijklm = μ + Bi + Rj + Gk + Sl + eijklm. Coefficients of genetic correlation between service period and milk traits were following: duration of lactation 0,239, milk yield 0,089, percentage of milk fat 0,095, quantity of milk fat 0,105 and yield of 4%FCM 0,099. Correlation between service period and age at calving was 0,535. Genetic correlation between age at calving and milk traits was following: duration of lactation 0,245, production of milk 0,003, percentage of milk fat 0,531, quantity of milk fat 0,082 and production of 4%FCM 0,050., Ispitivanje proizvodnih kapaciteta goveda u cilju povećanja proizvodnje mleka, mlečne masti i broja teladi, u velikoj meri zavisi od fenotipske i genetske varijabilnosti, heritabiliteta i povezanosti poželjnih osobina, kao i nivoa proizvodnje u populaciji. Ovim istraživanjem je obuhvaćena 3.461 kontrolisana prvotelka simentalske rase na imanjima individualnih poljoprivrednih proizvođača na području Republike Srbije. Genetske korelacije izračunate su jednačinom mešovitog modela koja uključuje uticaj bika-oca, odgajivačkog područja odnosno regiona, godine i sezone teljenja: Yijklm = μ + Bi + Rj + Gk + Sl + eijklm. Koeficijenti genetske povezanosti između servis perioda i osobina mlečnosti su sledeći: trajanje laktacije 0,239, prinos mleka 0,089, procenat mlečne masti 0,095, količina mlečne masti 0,105 i prinos 4%MKM 0,099. Povezanost servis perioda i uzrasta pri telenju iznosila je 0,535. Genetska povezanost uzrasta pri telenju sa osobinama mlečnosti iznosila je: trajanje laktacije 0,245, proizvodnja mleka 0,003, procenat mlečne masti 0,531, količina mlečne masti 0,082 i proizvodnja 4%MKM 0,050.",
