Abstract
Considering the fact that sheep production has an important role in agriculture of Serbia, lamb performance is essential. Objective of the study was to investigate effect of year, lambing season, sex and birth type on growth performances in lambs of MIS breed. Animal data (birth date, birth type, sex, birth weight -BW0, body weight after 30 days - BW30 and body weight after 90 days – BW90) are gained from control of productive parameters maintained from 2011 to 2020. Research was conducted on the sample of 1592 lambs. Average daily gain from birth to 30 days (ADG1), from 30 to 90 days (ADG2), and from birth until 90 days (ADG3), were calculated and included in analysis. Calendar year was divided in four seasons, each season consists from 3 months: winter, spring, summer and autumn. Average body weights (± standard deviation) at birth, after 30 and 90 days were 4.41 kg (± 0.99), 14.11 kg (± 2.80), 24.05 kg (± 3.86), respectively. Average daily gains were 319.87 g (± 74.97), ...164.98 g (± 35.39) and 216.88 g (± 36.86) for ADG1, ADG2 and ADG3, respectively. Lambing type and sex of the lambs affected all of the observed traits very significantly (p < 0.01). Lambing year had very significant effect (p < 0.01) on BW30, on ADG1 and ADG2, while lambing season significantly (p < 0.05) affected BW90, ADG2 and ADG3.Based on the results it can be concluded that birth type and sex had strongest effects in early productive parameters of lambs.

S obzirom na to da ovčarstvo ima važnu ulogu u poljoprivredi Srbije, produktivnost jagnjadi je od izuzetnog značaja. Cilj istraživanja je bio da se ispita uticaj godine, sezone jagnjenja, pola i tipa rođenja na produktivne parametre jagnjadi MIS rase. Podaci o životinjama (datum rođenja, tip rođenja, pol, telesna masa na rođenju -BW0, telesna masa posle 30 dana - BW30 i telesna masa nakon 90 dana - BW90) su dobijeni kontrolom proizvodnih parametara održanih od 2011. do 2020. godine, na uzorku od 1592 jagnjadi. Prosečan dnevni prirast od rođenja do 30 dana (ADG1), od 30 do 90 dana (ADG2), i od rođenja do 90 dana (ADG3), izračunat je i uključen u analizu. Kalendarska godina je podeljena na četiri godišnja doba (zima, proleće, leto i jesen), a svako godišnje doba sastoji se od 3 meseca. Prosečna telesna masa (± standardna devijacija) pri rođenju, posle 30 i 90 dana bila je 4,41 kg (± 0,99), 14,11 kg (± 2,80), 24,05 kg (± 3,86), redom. Prosečni dnevni prirasti iznosili su 319,8...7 g (± 74,97), 164,98 g (± 35,39) i 216,88 g (± 36,86) za ADG1, ADG2 i ADG3, redom. Tip rođenja i pol jagnjadi značajno su uticali na sve ispitivane osobine (p < 0,01). Godina rođenja imala je veoma značajan uticaj (p < 0,01) na BW30, na ADG1 i ADG2, dok je sezona jagnjenja značajno (p < 0,05) uticala na BW90, ADG2 i ADG3. Na osnovu rezultata može se zaključiti da su tip i pol rođenja imali najjače efekti u ranim produktivnim parametrima jagnjadi.
