Newborn lambs depend on their dams for passive transfer of immunoglobulins, primarily IgG, for protection from harmful pathogens until their own immunological defenses have developed. Previous studies have suggested that supplementation with Se results in a modest increase in IgG concentration in serum of newborn calves and lambs. To evaluate the effect of the Se source and supplementation rate...

Background: This study was conducted to evaluate the effects of feeding on biochemical parameters in terms metabolic profile female and male lambs Dorper Lacaune breeds at developmental stages from birth. Methods: A total 32 singleton newborn breed (n= 8 for each group; female) were used. The trial continued 5 nutritional periods 21-day after first two weeks (0-14 days) suckling period. determi...

The structure of the sheep cervix limits the application of reproductive biotechnologies such as embryo transfer and artificial insemination. The aim of this study was to determine differences in cervical anatomy and morphology between Sanjabi lambs and ewes, and the relationship between cervical anatomy and cervical penetration in ewes. Four hundred and sixty eight postmortum cervices belongin...

Suckling lamb meat is a relevant product in Mediterranean European dairy sheep farms, and the breed Spanish Assaf widely extended through Iberian Peninsula. Knowledge of influence birth body weight (bBW) growth rate on suckling carcass quality scarce, but useful for breeding optimisation homogeneity. In turn, these growth-related traits lambs might be affected by dietary restrictions their dams...

the data used in this research were according to survival rate records of 9700 lambs from 735 rams and 8082 ewes, which collected at moghani flock breeding research station during the year 1365 to 1390. the frequency distribution causes of culling and survival distribution function of lambs to yearling age were estimated by sas (2000). results revealed that 49.81 percent of total lambs were cul...
