Abstract
The research included a total of 921 lambs, 474 ewes and 8 sjenicke sheep rams from 4 different farms. The aim of the research was to examine the influence of the farm, cultivation technology and the influence of rams within the farm on production indicators. Statistical analysis showed that the body weight of lambs at birth ranged from 3.37 to 4.03 kg (average 3.68 kg), at 30 days from 11.51 to 12.41 kg (average 12.07 kg) and from 90 days from 27.82 to 29 kg (average 28.65 kg). A statistically highly significant influence of the farm was determined (P<0.01) on the body weight of lambs in all three control periods, as well as on the body weight of sheep and on the fertility of sheep. The influence of the ram on the body weight of the lambs at birth was statistically very significant within the farm (P<0.01). When it comes to the percentage share of birth type by farm, farm 1 had the most singletons (59.13%) both within the farm and in comparison between other farms, while t...here were fewer twins (40.87%), and triplets were not identified. On the other farms, the percentage of twins was the highest, and triplets were also present, while on farm 4 there were also quadruplets, lambs born as quadruplets (3.28%).

Istraživanjem je obuhvaćeno ukupno 921 jagnje, 474 ovce i 8 sjeničkih ovnova sa 4 različite farme. Cilj istraživanja je bio da se ispita uticaj farme, tehnologije gajenja i uticaj ovnova u okviru farme na proizvodne pokazatelje. Statistička analiza je pokazala da se telesna masa jagnjadi pri rođenju kretala od 3,37 do 4,03 kg (prosečno 3,68 kg), na 30 dana od 11,51 do 12,41 kg (prosečno 12,07 kg) i od 90 dana od 27,82 do 29 kg (prosečno 3,68 kg)28. Utvrđen je statistički visoko značajan uticaj farme (P<0,01) na telesnu masu jagnjadi u sva tri kontrolna perioda, kao i na telesnu masu ovaca i na plodnost ovaca. Uticaj ovnova na telesnu masu jagnjadi na rođenju bio je statistički veoma značajan u okviru svake farme (P<0,01).. Kada je reč o procentualnom učešću tipa rođenja po farmama, farma 1 je imala najviše jedinaca (59,13%) kako u okviru farme tako i u poređenju sa ostalim farmama, dok je blizanaca bilo manje (40,87%), a trojke nisu identifikovane. Na ostalim farmama procen...at blizanaca je bio veći a bilo je i trojki, dok su na farmi 4 bila i jagnjad rođena kao četvorke (3,28%).
