Abstract

The present study was carried out to find out if their any deferent impact of using  dried orange and citrus pulps as energy source on the performance, milk production, some rumen and blood parameters ofZaraibi does. The animals averaged 4 years old and weighed on average 45 kg. Fifteen animals were randomly divided into three similar groups (five animals each). The experiment was started at the last 8 weeks of gestation until three months after suckling period. The experimental rations were: R1(control ration ) consists of 50 % hay and 50 % concentrate which contain yellow corn grain . Does in the experimental rations  were fed  50 % of DOP( R2) and 50 % of DCP( R3) as partial replacement to yellow corn grains in the ration. At the end of the experiment the economic efficiency value was calculated. The Results could be summarized as follows: Feeding dried orange and citrus pulps increased nutrients digestibility (CP, CF, EE and NFE) and nutritive values as TDN, DCP compared to control ration.Dried orange and citrus pulp decreased total lipids and cholesterol .Also, increased total plasma protein and globulin significantly( p < 0.05) compared to the control group .Also,using dried citrus or orange pulps improved total milk yield and feed efficiency in all supplemented groups. It could be recommended that dried orange and citrus pulps( Oranges, tangerines, lemons)  can  safely replace a part of the energy sources included in rations at   50 %  in goats ration to reduce the feed cost and improve the performance and  milk production of goats.
