تأثير إضافة مستويات مختلفة من مسحوق الشاي الأخضر إلى العليقة على الأداء الإنتاجي ومستوى بعض المعايير الكيموحيوية للدم في ذكور الأرانب النامية

Abstract

This study was conducted to evaluate the effect of adding different levels of green tea powder as an antioxidant and its effect on the productive performance and some biochemical parameters of the blood serum of growing male rabbits. In this study, 48 male New Zealand white rabbits growing at 4 weeks of age were used, with an average weight of 630 ± 12.8 g, randomly assigned to 4 treatments with 3 replicates for each treatment, and one replicate contained 4 rabbits. The experiment lasted for 8 weeks and the experimental treatments were as follows: T1 as the control treatment without any addition, T2, T3, and T4 included adding green tea powder at the rate of 0.5, 1, and 1.5%, respectively. The results indicated that rabbits fed on green tea powder had a significant improvement (P≤0.05) in live body weight, total weight gain and food conversion efficiency of the addition treatments compared to the control treatment without additives, while a significant decrease of these treatments was observed in the rate of feed consumption when compared to the control diet, which recorded the highest feed consumption rate of 4827.65 g/rabbit. The results also showed that adding green tea powder led to a significant decrease (P≤0.05) in the proportion of total lipids, cholesterol, triglycerides and glucose in rabbit blood serum when compared with the control group. While adding green tea powder had no significant effect on the total protein content. It was found from this study that the use of green tea powder has a positive effect on performance and improvement of some biochemical parameters of blood in growing male rabbits.
