This experiment aims to study the growth situation of rabbits whose forage is replacedpartially by different levels of Pleurotus ostreatus substrate. Thirty-two rabbits were divided into 4 groups randomly,which adds 0,3%,6%,9% Pleurotus ostreatus substrate replacing the same quality forage to basaldiet. Then we measured their growth performance,the biochemical indexes of blood and serum,and economic benefits. The results showed that there was no significant difference in weight gain and blood biochemical in...
