an experiment was conducted to evaluate the extracted (es) and mechanical (ms) soybean meals two levels 25% and 35% in broiler chicken feeding. three hundred and fifty two one-day-old unsexed lohman chickens were placed in four treatments by 4 replicates and 22 chickens in each in a 2×2 factorial arrangement. feed intake was increased significantly in starter period by es in comparison with ms....

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...
