Abstract EN
The study was aimed to investigate the effect of some non-genetic factors )lamb’s gender , type of birth TB , dam’s age AD , lambing season LS and lamb’s age LA( on serum biochemical levels (cholesterol CH , total protein TP, glucose GL and activity of Aspartate aminotransferase AST and Alanine aminotransferase ALT enzymes) and growth traits (birth weight BW , weaning weight WW , 7 months weight 7MW and average daily weight gains from birth till weaning ADG1 and from weaning till 7 months of age ADG2).
The results revealed significant effect (P<0.05) of lamb’s gender on BW with the superiority of males upon females, while TB , AD and LS showed no significant effect on all studied traits.
Obtained results showed significant effect (P<0.05) of TB , LA on TP with the superiority of single born lambs and lambs of 5 weeks of age upon twin born lambs and lambs of 13 weeks of age respectively.
All non-genetic factors had no significant effect on CH and GL , while they had significant effect (P<0.05) on AST activity with increased AST in male, single born, winter born lambs in comparison with female, twin born and autumn and summer born lambs .
Lambs of 5 and 13 weeks of age had significantly higher AST activity than other age groups of lambs.
Only LS and LA had significant (P< 0.05) effect on ALT activity which increased significantly (P<0.05) in winter born lambs in comparison with autumn and summer born lambs, also ALT activity increased significantly (P<0.05) in lambs at 5 weeks of age from that’s of 3 weeks and 9-23 weeks of age.
Positive significant (P<0.01) correlations recorded between TP and AST activity (0.28) and between AST and ALT activities (0.42).
AST activity showed negative non significant correlation with most of body weights and body weight gains.
All other correlation were positive non significant.
