The current study was aimed to investigate the influence of Vitamin A- Palmitate injection and grazing on some physiological and biochemical characters, milk yield and its compositions. Twenty eight Meriz does (2 years aged) after parturition with average body weight 22.57 ± 0.47 Kg, and were randomly assigned into 4 groups (7 does/group) treated for 3 months as following: 1st group does were reared on standard ration and injected with 0.05 ml of physiological saline i.m weekly, 2nd and 4th groups, does were reared on standard ration and injected with vitamin A- Palmitate (50000 IU/doe weekly) as well as grazing for 6 hrs. daily for the does in 4th group, 3rd group does were reared on standard ration with 6hrs grazing /daily. Results showed a significant increase in Hb and PCV in 4th group at 1st, 2nd and 3rd month of treatment. ESR significantly increased in 4th group at 3rd month of treatment, also serum glucose level increased significantly in 2nd and 4th groups at all months of the study, while serum cholesterol level decreased significantly in 4th group at 2nd and 3rd months of treatment. Triglyceride increased at 3rd month in all treatments as compared with control, total protein and albumin increased significantly in 2nd, 3rd and 4th groups at 2nd and 3rd months of treatment. A significant increase in milk yield and fat% were recorded in 2nd, 3rd and 4th treatments in most kidding weeks. Conclusion, results showed that vitamin A and grazing improved some of physiological, biochemical, body weight and milk yield in Meriz goats.

In the current study, 32 Awassi ewes 2 -3 years aged were used with their lambs for 12 weeks, to evaluate the effect of Body Weight (BW) and Milk Yield (MY) on Body weight BW, Body Weight Gain (BWG), MY and milk components. After lambing, ewes were weighted directly, then at the 1st week of lambing, ewes were milked for 2 consecutive days, in order to determine the milk yield, Ewes divided randomly to 4 groups depending on their body weights and milk yield, the groups were: 1st group: ewes with high BW and high MY, 2nd group: ewes with high BW and law MY, 3rd group: ewes with low BW and high MY, 4th group: ewes with low BW and low MY. The result showed a significant increase (P≤0.05) in BW in heavy ewes (HE) groups at the 2nd, 4th, 6th and 8th weeks, the best significant interactions (P≤0.05) were recorded in the 1st, 2nd and 3rd group at 8th weeks. Also, there is a significant increase (P≤0.05) in BWG in the HE at 8th week. The effect of MY was evident in milk production, MY of HW and high milk (HM) increased significantly at the 2nd, 4th, 6th and 8th weeks. Also a significant increase (P≤0.05) in milk fat% in HM ewes at 2nd, 6th and 8th weeks after lambing. On other hand the results revealed a significant increase (p≤0.05) in lactose % in Light Ewes Milk (LE) at 8th week and Low Milk Ewes (LOM) at 4th week, also solid non-fat components % increased significantly in LE at 2nd week and HW ewes. In conclusion, the body weight of the lambs that born from the ewes with (heavy weight and high milk production) were significantly higher than other lambs, also, milk production of these ewes was significantly (P≤0.05) higher than other groups.
