متن کاملEnergy Partitioning and Tissue Respiratory Metabolism of Laying Chickens Reared under Summer Conditions of Egypt
A total number of 156 laying chickens at 29 weeks of age were used in the study. Birds were distributed equally in two dietary energy levels (2600 and 2900 Kcal ME/Kg feed) and three strains viz., Lohmann Selected Leghorn (LSL), Fayoumi and Dandarawi. Three experiments were conducted to measure energy partitioning values (36 birds), liver oxygen consumption and oxygen consumption of epithelium ...
متن کاملImpacts of Dietary L-Threonine Supplementation on Performance and Intestinal Morphology of Broiler Chickens during Summer Time
The present study evaluated effects of 0.0%, 0.5%, 0.75% and 1.0% L-threonine in diet on performance and gastrointestinal tract development in broiler chickens during summer. From 0 to 42 days old, body weight gain was greater in 0.75% L-threonine fed birds than in 0.0% and 0.5% L-threonine fed birds (P0.05). During the growth period, 0.75% L-threonine fed birds had the highest body weight gain...
