Investigating the affected methods in the first 48-hours of nutrition on performance of broiler chicks

The experiments to evaluate the effect of different feeding methods on weight gain of broilers were reared in the first 48 hours of nutrition. In this study 480 broiler of chicks were used in a completely randomized design. Rations were: 1: Water + initial grain (Crumble), 2: water + sugar + Early grain (Crumble), 3:water + feed opening (Crumble) + Multi-vitamins and electrolytes, 4:water + sugar + initial grain (Crumble) + Multi-vitamins and electrolytes, 5:water + cornstarch + multi-vitamin and electrolyte and 6: water + initial feed (mesh) + were multivitamins and electrolytes. Each treatment had four replicates and each replicate contained 20 chicks. The total period of weight gain, water treatment + initial grain (crumble) + Multi-vitamins and electrolytes showed the highest yield among the treatments . These results indicate that the initial, growth and end period, use of the whole grain in form of Crumble along with water and multivitamin and electrolytes had the best performance in terms of weight gain, and use of sugar in water did not have positive efficiency. Chicks access the full grain in form Crumble and water, multivitamins, and electrolytes was provided in the first 48 hours have been eating more. In the whole period, the treated water + grain + multivitamins and electrolytes significantly had lower FCR than the diet contain, water+ initial seed (Crumble ) but in the sense of carcass yield and percent of mortality there is no significant difference observed between treatments (P <0.05).
