Effect of dietary calcium level on growth performance, phosphorus digestibility and bone mineralization of lean-type growing-finishing pigs fed a low phosphorus diet supplemented with phytase

摘要

An experiment was conducted to determine the effect of dietary Ca level and phytase on growth, bone strength and digestibility of P and Ca in growing-finishing pigs. High lean-type pigs were randomly allocated to treatments on the basis of weight and gender. Average initial weight was 23.4kg and the experimental period was 111 days. Each treatment was replicated five times with five pigs per replicate.
