Abstract

This experiment was conducted to investigate the effects of plant polysaccharide and puerarin on growth performance, serum biochemical indices and meat quality of captive goats. Thirty 4-month-old female Chuanzhong black goats were randomly assigned into 3 groups with 10 replicates in each group and 1 ewe in each replicate. The goats of control group were fed with a basal diet, but the goats of polysaccharide group and puerarin group were fed with the basal diet plus 0.1% plant polysaccharide and 0.04% puerarin, respectively. The experimental period was 70 days, of which the pre-feeding period was 10 days and the trial period was 60 days. The results showed that compared with the control group, the average daily gain (ADG) of the polysaccharide group was significantly increased (P<0.05), but its feed/gain was significantly decreased (P<0.05), no significant differences were noticed in them of the puerarin group (P>0.05). And also, the content of high-density lipoprotein (HDL) in serum of polysaccharide group and puerarin group was significantly increased (P<0.05), but serum urea content of polysaccharide group was also significantly increased (P<0.05). In addition, the value of yellowness (b*) in muscle of the polysaccharide group and puerarin group was significantly decreased (P<0.05), and the shear force of puerarin group was significantly decreased (P<0.05). The above results indicate that plant polysaccharide can promote the nutrient metabolism and enhance the growth performance of captive goats, and puerarin can improve the meat quality, but has no improvement effect on growth performance of captive goats.
