Some Blood Biochemical Parameters and Yield of Lambs Fed Ration Contained Dried Grape Pomace

An experiment was conducted to evaluate the effects of inclusion of different levels of dried grape pomace (DGP) in ration of male lambs on some biochemical parameters such as cholesterol (Choi.), triglyceride (TG), total protein (TP), hematocrit, hemoglobin contents and the growth performance . Twenty-five 100-day-old Lori-Bakhtiari male lambs obtained with an initial live weight of 25 ± 0.21 kg were fed the experimental rations, which were formulated in accordance with the NRC-1994. Treatments were arranged in a completely randomized design of five treatments with 5 replicates each (0, 5, 10, 15 and 20% DGP) and lambs were observed during 84 days growth period. Dry Matter Intake (DME) was daily measured and daily weight gain (DWG) was determined fortnightly. Feeding male lambs on diets containing 5 and 10 % DGP significantly improved their growth performance (P<0.01) as compared to the other treatments. Among biochemical parameters, TG level was significantly increased by diet supplementation of DGP as compared with control. Amounts of TP, hematocrit and hemoglobin of blood did not change by inclusion of DGP In conclusion, inclusion of 5% DGP in the ration could be useful in fattening male lambs with considerable low blood TG and Cholesterol contents.
