Sažetak
The aim of this research was to determine birth weight and average daily gain of Lika Pramenka lambs from birth to slaughter (sale), or the reached age of 127 days. The research was conducted on a family farm Obućina which for decades occupy with rearing of Lika Pramenka sheep and lamb meat production. The research included a total of 101 lambs (55 female and 46 male and 83 singles and 18 twins). In order to determine birth weight, lambs were weighted immediately after birth (MASS1), then at an average age of 48 days (MASS2) and at an average age of 127 days (MASS3). Based on the determined body weights of lambs average daily gains were calculated: DG1 (from birth to 48th day), DG2 (from 48th to 127th day) and DG3 (from birth to age of 127th day). The average birth weight of Lika Pramenka lambs of 3.19 kg was determined. Average values of determined daily gains were: DG1 202.29 g; DG2 158.61g; and DG3 173.84g. It was determined statistically significant effect of litter size on body weight (P<0.05) and average daily gain (P<0.001) of Lika Pramenka lambs. Although male lambs immediately thereafter births were heavier then female, determined differences were not statistically significant (P≥0.5). Likewise, lambs gender didn't statistically significant influenced on average daily gain of lambs at the begining of fatening (DG1), when daily gains in second phase (DG2) and total average daily gain (DG3) were statistically significant influenced by lambs gender (P<0.01; P<0.05). Male lambs had significantlly higher DG2 and DG3 then female lambs.
