High-fiber diets with reduced crude protein for commercial layers

Feeding reduced crude protein diets with crystalline amino acids supplementation reduce air gas emissions from housing.

The objective of this study was to test the hypothesis that reducing dietary CP by 1.5% and supplementing crystalline AA (CAA) to meet the standardized ileal digestible (SID) AA requirements for growing and finishing pigs decreases air emissions of ammonia (NH), nitrous oxide (NO), and carbon dioxide (CO) compared with an industry standard diet, without reducing growth performance. Seventy-two ...

The Effects of Probiotic and Thyme Powder on Growth Performance, Carcass Traits and Blood Biochemical Parameters of Broilers with Normal and Crude Protein Reduced Diets

Extentet Abstract Introduction and Objective: Substances of microbial origin and medicinal plants, by improving the level of health and condition of the gastrointestinal tract, provide the basis for the optimal use of nutrients in diets, and by reducing the use of nutrients, while saving production, also prevent environmental pollution. Dietary protein sources are among the most expensive nutr...

Supplemental L-arginine Modulates Developmental Pulmonary Hypertension in Broiler Chickens Fed Reduced-Protein Diets and Reared at High Altitude

This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...
