Abstract :

The present study was carried out to evaluate the impact of adding a fixed amount of Peppermint0.5 gm / kg LBW/ day to rations containing dried orange(DOP) or citrus pulps( DCP )as energy sources on milk production, some rumen and blood parameters of Zaraibi does ( Twenty animals averaged 4 years old and weighed on average 45 kg ). The experiment was started at the last 8 weeks of gestation until three months of suckling period. The experimental rations were : R1(control ration ) consists of 50 % hay and 50 % concentrate mixture which contained 30 % yellow corn grain whileR2( positive control ration) consists of the control ration ( R1)  + 0.5 gm Peppermint / kg LBW/ day.However,50 %of corn grains in the R1was replaced with 50 % of dried orange pulp (DOP) + 0.5 gm Peppermint / kg LBW/ day ( R3) and 50 % of  dried citrus pulp (DCP) + 0.5 gm Peppermint / kg LBW/ day ( R4) . At the end of the experiment the economic efficiency was calculated. The Results could be summarized as follows: Feeding goats on rations contained dried orange or citrus pulps+ 0.5 gm Peppermint / kg LBW/ day increased nutrients digestibility (CF,CP, EE and NFE) and nutritive values (TDN and DCP) compared to control ration. Dried orange or citrus pulp+ 0.5 gm Peppermint / kg LBW/ day decreased plasma total lipids and cholesterol concentrations, while total plasma protein and globulin were significantly (P<0.05) increased compared to the control group. Also, improved total milk yield and feed efficiency in all supplemented groups. It could be recommended that adding 0.5 gm Peppermint / kg LBW/ day on dried orange or citrus pulps (Oranges, tangerines, lemons) can safely used to replace a part of the energy sources such as corn grain in rations at 50 % in goats ration to reduce the feeding cost and improving the performance of milk production of goats.
