Effect of Feeding Low Protein Diets on the Production Traits and the Nitrogen Composition of Excreta of Broiler Chickens

The main goal of the current study was to investigate effects feeding low protein (LP) diets on performance parameters and excreta composition broiler chickens. In total, 288 male Ross 308 day-old chickens were divided into two dietary treatment groups using six replicate pens with 24 each. No LP diet fed in starter phase. reduction grower finisher phases 1.8% 2% respectively. Beside measurements production traits, day 40 representative fresh samples collected, their dry matter, total N, NH4+-N uric acid-N contents determined, ratio urinary fecal N calculated. Dietary treatments failed cause significant differences feed intake, growth rate, conversion animals. decreased nitrogen acid significantly. age birds had also effect, resulting more phase compared finisher. higher at 24. content chicken’s is lower than can be found literature, which should considered ammonia inventory calculations.
