AB  - This research was conducted with the aim оf estimating genetic trend for a functional length of productive life (FLPL) in the population of Black and White cattle in Serbia. Research and bulls genetic evaluation for functional longevity were performed on a set of data provided by Agricultural Corporation Belgrade AD (PKB) which contained data on longevity and origin of 22109 cows out of which 26% records were right-censored. Functional length of productive life (FPLP) represents a time period from the first calving to culling or censoring corrected for milk production. Breeding values were estimated using Weibull method of proportional risks within survival analysis a genetic trend for FLPL was calculated using of a regression analysis. The cows included in the analysis were on average first calved in the age of 809 days and had an average share of 81.9% genes of Holstein Friesian breed. An average length of productive life was 1267 days (41.6 months). Distribution of bull standardised breeding values did not statistically significantly differ from normal distribution. An average standardised breeding value was 99. A slightly positive genetic trend was determined, that is, the length of functional productive life was by selection increased by 0.021 day at an annual level while a reliability of estimated breeding values showed a negative trend.

AB  - In order to have a more precise description of dairy farm structure and characteristics of dairy production systems, as well as to assess possibilities for improving production and farming conditions in which milk production is organized, a survey based research was directed at a select group of farms across the Serbia. 1180 questionnaires have been mailed to farmers whose farms are registered for either cattle or mixed production. Questionnaire was divided into 6 sections: general information of the farm, agricultural and structural information, zootechnical information, sanitary and veterinarian information, information about education and extension, and information on the perspectives of future farming. About 59% of analyzed farms have size up to 20 ha, with average size of about 10 ha. On the other hand, about 55% farms raises up to 15 cows and heifers with average of 6 heads per farm, while 3% of farms have more than 200 cows and heifers. Over 86% of surveyed farmers intend to expand existing farm production, mainly by increasing the number of animals, stricter selection and improvement of the conditions for feeding, housing, care and milking. About 75% of farmers have expressed a positive expectation from future membership of Serbia in EU, although these expectations are not clearly defined.

Ukupno je poslato 1180 anketa farmerima čije su farme registrovane za govedarsku ili mešovitu proizvodnju. Upitnik koji je poslat farmerima sastojao se iz 6 delova i obuhvatao je opšte informacije o farmi, poljoprivredne i strukturne informacije, zootehničke informacije, sanitarne i veterinarske aspekte proizvodnje, edukaciju i savetodavstvo, kao i perspektive budućeg poslovanja. Oko 59% analiziranih farmi ima veličinu do 20ha, sa prosekom od oko 10ha. Sa druge strane, na oko 55% farmi odgaja se do 15 krava i junica, sa prosekom od 6 grla po farmi. Preko 86% anketiranih farmera namerava da proširi postojeću proizvodnju i to uglavnom povećanjem broja životinja, strožijom selekcijom roditeljskih parova, kao i unapređenjem uslova ishrane, smeštaja i nege. Oko 75% anketiranih farmera izrazilo je pozitivna očekivanja od budućeg članstva Srbije u EU, iako ta očekivanja nisu uvek jasna ili precizno definisana.

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  - 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. Bull dams of Simmental breed selected on farms of individual agricultural producers were investigated. The method of Least Squares LSMLMW(Harvey 1987) was used for analysis of the effect of year and season of calving on reproductive traits. Year of calving had significant effect on duration of service period and interval between calving (p (lt) 0.05), while season influenced significantly only the duration of service period (p (lt) 0.05). Mean values of the general average were following: for age at first conception - 517.61 days; duration of pregnancy 285.51 days; duration of service period 108.98 days; duration of interval between calving 395.34 days.
AB  - Ispoljenost reproduktivnih osobina bikovskih majki simentalske rase bila je na zadovoljavajućem nivou. U daljem odgajivačko-selekcijskom radu treba nastojati da se omogući dobijanje jednog teleta godišnje. Opšti prosek sredine najmanjih kvadrata osobina plodnosti iznosio je za uzrast pri prvoj oplodnji 517.61 dana,trajanje bremenitosti 285.51 dana, trajanje servis perioda 108.98 dana, dužina međutelidbenog intervala 395.34 dana. Godina telenja statistički je značajno uticala na trajanje servis perioda i dužinu međutelidbenog intervala (P (lt) 0,05), za razliku od uzrasta pri prvoj oplodnji i trajanje bremenitosti na koje nije imala značajan uticaj (P>0,05). Sezona telenja imala je signifikantan uticaj samo na trajanje servis perioda (P (lt) 0,05), dok na ostale ispitivane parametre plodnosti nije imala značajnijeg uticaja (P>0,05).

abstract = "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. Bull dams of Simmental breed selected on farms of individual agricultural producers were investigated. The method of Least Squares LSMLMW(Harvey 1987) was used for analysis of the effect of year and season of calving on reproductive traits. Year of calving had significant effect on duration of service period and interval between calving (p (lt) 0.05), while season influenced significantly only the duration of service period (p (lt) 0.05). Mean values of the general average were following: for age at first conception - 517.61 days; duration of pregnancy 285.51 days; duration of service period 108.98 days; duration of interval between calving 395.34 days., Ispoljenost reproduktivnih osobina bikovskih majki simentalske rase bila je na zadovoljavajućem nivou. U daljem odgajivačko-selekcijskom radu treba nastojati da se omogući dobijanje jednog teleta godišnje. Opšti prosek sredine najmanjih kvadrata osobina plodnosti iznosio je za uzrast pri prvoj oplodnji 517.61 dana,trajanje bremenitosti 285.51 dana, trajanje servis perioda 108.98 dana, dužina međutelidbenog intervala 395.34 dana. Godina telenja statistički je značajno uticala na trajanje servis perioda i dužinu međutelidbenog intervala (P (lt) 0,05), za razliku od uzrasta pri prvoj oplodnji i trajanje bremenitosti na koje nije imala značajan uticaj (P>0,05). Sezona telenja imala je signifikantan uticaj samo na trajanje servis perioda (P (lt) 0,05), dok na ostale ispitivane parametre plodnosti nije imala značajnijeg uticaja (P>0,05).",

AB  - Major fattening and growth traits of performance tested bulls from two groups are presented in this paper. Bulls obtained in pure breed Fleckvieh x Fleckvieh were investigated/evaluated in test stations in Germany, and male crosses with Domestic Simmental cows in domestic centers for AI (Krnjača and Velika Plana). In observing two groups of young bulls statistically significant differences were registered (p (lt)  0,01**) for following traits chest depth, chest girth, and daily gain, whereas for body mass at the end of test and height of withers differences were at level p> 0,05 ns. Group of young bulls F x F tested in Germany achieved in average greater chest depth and chest girth and realized higher daily gains during test period. Group of crosses tested in our conditions in domestic test stations realized higher values for length of carcass and almost identical body mass at the end of test period. In other words, improvement of production traits and correction of exterior characteristics of domestic population of cattle through import of breeding animals and their semen is justified only when positively tested breeding material is imported which is adequate for our purpose and breeding objective.

AB  - Realization of the programme of crossing of Domestic spotted cattle with meat cattle breeds in order to obtain cattle for export (live or as beef) has following production effects: 	- Intensifying of the fattening ability, 	- Improvement of the meat quality by crossing (crossbreds F1 generation), 	- Increased dressing percentage of the carcass, and 	- Realization of higher price (by10-15%) for 1 kg of body mass in export; 	- Reduced cost of feed per 1 kg of gain. 	Improvement of the quality of meat by application of this programme will be achieved in color, firmness, fineness of muscle fibers, marbling and flavor of meat. Majority of mentioned traits is significant in relation to quality as well as the price of 1 kg of meat for export. Dressing percentage of carcass of domestic spotted cattle is extremely low - 53-56%. With this programme higher by 3-4% dressing percentage will be achieved. Cattle obtained by crossing are expected to have an average dressing percentage of 59-60%. 	 Economical efficiency of the production of beef depends on realized daily and total gain of body mass, dressing percentage, quality of meat and cost of feed per 1 kg of gain. Farmers are very interested in realizing high gain with lower costs of feed (conversion) per 1 kg of gain, whereas slaughterhouses and processing plants define their interest in high dressing percentage and quality of meat, as well as export orientation, since in this way they are able to increase the price of meat by 10-15% per 1 kg of carcass sides. Results of carried out researches are beef of high quality for domestic and foreign market. Complete results of mentioned researches will contribute to considerable increase of yield of beef, carcass sides, meat sections of the highest quality, meat in chunks packaged according to moder standards. Obtained results - products will be placed on the market, presented in specialized journals and on numerous scientific meetings and symposia.
