he present study was carried out to study the impact of using some medicinal herbs (0.3gm Garlic / kg LBW/ day (R2), 0.2 gm Lemongrass / kg LBW/ day (R3), 0.5 gm Peppermint/ kg LBW/ day (R4) ,0.2gm Rosemary / kg LBW/ day (R5) versus an supplemented ration (R1control ration which consists of 70% concentrate and 30% hay without any additives) on growth performance , some rumen and blood parameters of twenty five growing Barki lambs. The animals averaged 5-6 months old and weighed on average 26 kg. Animals were randomly divided into five similar groups (five animals each) for 120 days growth trial. The economic efficiency values were calculated. The Results could be summarized as follows: Feeding herbs improved all nutrients digestibility (DM, OM, CP, CF, EE and NFE) and nutritive values as TDN, DCP compared with control ration. Medicinal herbs decreased total lipids and cholesterol .Also, increased total plasma protein and globulin significantly (p < 0.05) compared to the control group. Feed efficiency (gm gain / gm DM or TDN) was enhanced in all supplemented groups compared with the control ration. It could be recommended to use 0.3 gm Garlic or 0.2gm Lemongrass or 0.5 gm Peppermint or 0.2gm Rosemary / kg LBW/ day to enhance growth and improve economic efficiency of production and to decrease plasma cholesterol and total lipids in lambs blood .

he present study was conducted to investigate the impact of adding different levels of dried Pomegranate by-products (DPB):10g/head /day (R2), 20g/head /day (R3), 30g/head /day (R4),versus an supplemented ration (R1) control ration which consists of 70% concentrate and 30% alfalfa hay without any additives) on growth performance, blood parameters , feed efficiency and economical efficiency of twenty growing Barki lambs (averaged 5-6months old and weighed on average 28kg ) in the growth trial(120 days ) . Twelve adult rams (weighed 42 kg) were used in digestion trials to estimate nutritive values, digestion coefficient, some rumen parameters. The Results could be summarized as follows: Pomegranate by-products contained numerous active metabolites such linalool, myrcene, menthol and thymol. The DPP contained 380, 149, 71, 172 and 65 mg/100 g of Ca, P, Na, K, and Mg, respectively. Also, it contained Se, Fe, and Zn respectively. Moreover, it contained vitamin C; vitamin E, vitamin A, vitamin B 1 and vitamin B2. Adding different levels of dried Pomegranate byproducts (DPB):10g/head /day ( R2), 20g/head /day ( R3), 30g/head /day ( R4), improved all nutrients digestibility (DM, OM, CP, CF, EE and NFE) and nutritive values as TDN, DCP compared with control ration. The highest significant (P<0.05) values were found with lambs fed ration containing 20 g/ head/day of DPB (R3) followed by 10 g/ head/day of DPB (R2) compared to the control group. Also, adding different levels of dried Pomegranate by-products (DPB) improved the blood parameters .Pomegranate by-products decreased cholesterol level in plasma, with the highest effect for R3 followed by R2 and R4 compared to the control group. Moreover, Pomegranate by-products significantly (P<0.05) decreased total lipid and increased total plasma protein and globulin comparing with the control group. Additionally, Pomegranate by-products significantly (P<0.05) improved the daily gain by175.8 g , 175 g ,158.3g for R2, R3, R4, respectively compared to the control group by 150g .Also, Pomegranate byproducts significantly (P<0.05 ) increased the economic efficiency for growing lambs . The effect was the highest for R2 and R3 followed by R4 compared to control group. Referring to the obtained results, it could be recommended that adding 10-20 g / head /day of dried Pomegranate by-products in growing lambs ration exhibited positive effect on productive performance of Barki lambs, weight gain, feed efficiency and economic efficiency, and decrease plasma cholesterol and total lipids.

he 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 of Zaraibi 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.

he 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.
