Abstract

The purpose of this experiment was to investigate the effects of different supplemental levels of beer yeast on growth performance, fur quality, slaughter performance and meat quality of growing Rex rabbits. A total of 120 healthy white Rex rabbits (male and female half) with a similar body weight at (30±2) days of age were divided into 4 groups with 30 replicates per group and 1 rabbit per replicate. Rex rabbits in the control group was fed a basal diet, and those in test groups Ⅰ, Ⅱ and Ⅲ were fed the experimental diets that replaced the soybean meal of basal diets with 5, 10, 15 kg/t beer yeast, respectively. The pre-feeding period lasted for 7 days, and the experimental period lasted for 60 days. The results showed as follows:1) compared with the control group, dietary beer yeast had an improving trend on average daily gain and feed/gain of growing Rex rabbits (P>0.05). The average daily gain and feed/gain were the best when the supplemental level of beer yeast was 10 kg/t. 2) Compared with the control group, dietary beer yeast had an improving trend on wool density, wool length, fur area and fur weight of growing Rex rabbits (P>0.05). 3) Compared with the control group, dietary beer yeast had significant influence on the carcass weight of growing Rex rabbits (P<0.05). 4) Compared with the control group, dietary beer yeast had significant influence on shear force, pH_{45 min} and drip loss of meat in growing Rex rabbits (P>0.05). Considering all indices of this experiment, the appropriate beer yeast supplemental level in the diet of growing Rex rabbits is 10 kg/t.
