Abstract

Feeding ewes diets with higher energy and crud protein during gestation and lactation affects the performance of lambs at weaning. The objective of this study was to determine the nutrition plane supplementation during pregnancy and lactation period affects ewes and their offspring performance. from birth to weaning. Twenty four Ossimi ewes with average weight 55.67 kg and aged 2-4 years old and their offspring (n=30) were used in completely randomized design consisting of three supplementation level (high,125%ME; standrd,100% ME and low, 60% ME) of predicated metabolizable energy requirements according to NRC, 1985. The ewes were weighted and the body weights of lambs were recorded from birth to weaning. Colostrum production was recorded during the first week after parturition, the amount of milk production was estimated after that weekly until weaning. Blood samples were also collected from the ewes and analyzed to determine blood components. There was no effect of nutrition plane on live body weight of ewes during pregnancy and lactation period. Ewes were had significantly (P≤0.01) higher colostrum and milk yield compared with ewes offered medium ME or low group. The values of TMY, ADMY and colostrum yield were significantly (P≤0.01) higher in ewes fed high ME diet compared with ewes fed on medium or low ME diet. All blood constituents were not affected by nutrition plane during pregnancy except for cholesterol and glucose levels were affected significantly (P≤0.05), Likewise, during the lactation period, with the exception of cholesterol levels, which were significantly (P≤0.05) affected. There was a significant (P≤0.05 or P≤0.01) increase in body weight and daily gain for lambs resulting from ewes offered high ME diet compared ewes offered medium ME or low ME diet. In conclusion it can be said that, nutrition plane is every important of ewes during pregnancy and lactation period and feeding the ewes at high ME can improve the performance of growth and milk production without any negative effect on the blood components.
