Nutritional management to reduce environmental impact for sustainable animal production
2004
Paik, I.K.
The animal industry must be environmentally sound to ensure its long-term sustainable growth. In order to prevent pollution from animal waste, P, N, and pharmacological level minerals should be properly managed. Microbial phytase has been successfully used to control P excretion. The activity of natural phytase in certain plant feedstuffs is high enough to be considered in feed formulation. Nitrogen control can be achieved through amino acid supplementation and protein restriction in the diet. Supplementation with carbohydrases reduces output of excreta as well as N. Ammonia release from the manure can be reduced by using a low crude protein diet along with the supplementation of probiotic products. Excretion of minerals can be reduced by using them in chelated forms. Copper and Zinc in the form of methionine chelate have been successfully used in the diets of broilers, layers and/or pigs.
