Abstract
Abstract This study was conducted to evaluate the effect of adding different levels of rocket salad to the diet on physiological performance of laying breeder roosters. A total of 60 White Hy – Line laying breeder roosters, 32 weeks of age were used in this study. Roosters were randomly distributed into 4 treatment groups of 3 replicates each and each replicate constituted of 5 roosters (15 roosters for each treatment groups). Experimental treatments were as following: T1: control group (Without any addition to the diet), T2, T3, and T4: adding rocket salad seeds at levels 1, 2, and 3 Kg / ton of the diet, respectively. Rocket salad seeds were added to the diet of birds from 34 weeks of age to the end of experiment which lasted 24 weeks. At the end of each month of experiment blood was collected from 9 roosters in each treatment group to evaluate concentration of glucose, protein, cholesterol, calcium and phosphorus and activities of glutamateoxaloacetate transaminase (GOT), glutamatepyruvate transaminase, and alkaline phosphatase (ALP) enzymes in blood plasma. Results revealed that supplementation of the roosters ration with rocket salad seeds resulted in significant increase as regards concentration of protein, calcium, and phosphorus and activity of ALP enzyme in blood plasma and significant decrease concerning concentrations of glucose and cholesterol and activities of GOT and GPT enzymes in blood plasma during most months of experiment and with relation to the total mean of these traits. However, T4 (3 Kg of rocket salad seeds / ton of diet) recorded the best results respecting all blood plasma constituents included in this study. In conclusion supplementing diet with rocket salad seeds especially at the level of 3 Kg / ton of diet resulted in improvement as concerns blood plasma constituents of roosters. Therefore, rocket salad seeds could be used as an important tool for improving physiological performance of birds.
