Abstract

The aim of this experiment was to determine the digestible Valine requirement of male Ross 308 Broiler chicks in grower period. To evaluate Valine requirement of male Broiler chicks based on growth performance, a total of 450one day old male Broiler chicks from8 to 21days of age, was assigned to 6 treatments with 5 replicate using a completely randomized design. Dietary Valine was supplied in 6 levels from 0. 74, 0. 79, 0. 84, 0. 89, 0. 94 and 0. 99for the experimental period. Results of this study showed that the quadratic Broken Line Model were used for determine of digestible Valine requirement for Ross 308 male Broiler chicks is the well fitted base on weight gain, Feed Conversion Ratio and breast weight and Evaluated digestible Valine content for these three performance parameters were 0. 93, 0. 91 and 0. 84 % of diet (Val/lys were 88, 86 and 79%), respectively. The result of this experiment showed that the all performance parameters and cell modified immune response were significantly affected by the Valine supplementation in diet (P< 0. 01). The Broiler chickens fed with 0. 89 % of digestible Valine level had the highest cell modified immune response (1. 13± 0. 05 mm) and the lowest Feed Conversion Ratio (1. 42± 0. 02) (P<0. 01), and also The Broiler chickens fed with 0. 74 % of digestible Valine level had the lowest cell modified immune response (0. 44± 0. 03 mm) and the highest Feed Conversion Ratio (1. 60± 0. 06).
