Nutritional Management to Control Environmental Impact in the Sustainable Animal Production

InKee PAIK
The animal industry must be environmentally sound to insure 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 used successfully to control P excretion. 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.

Ammonia release from the manure can be reduced by using a low crude protein diet along with the supplementation of probiotics products. Excretion of minerals, which are used at pharmacological level can be reduced by using chelated forms. Cu and Zn in the form of methionine chelate have been successfully used in the diets of broilers, layers and/or pigs.
