EFFECT OF DIETARY SUPPLEMENTATION WITH FERMENTED SOYBEAN MEAL ON GROWTH PERFORMANCE, LIPIDS METABOLISM AND IMMUNITY OF TLRI BLACK PIG NO. 1.

The aim of this study was to investigate the effects of feeding probiotics on growth performance, nutrients digestibility, lipids metabolism and immunity in growing-finishing TLRI black pig No. 1. Total of 48 pigs weighing 32 kg were randomly allotted into three treatments. There were two pigs per replicate(pen) and eight replicates per treatment. Control group was fed with basal diet, probiotics A which contained basal diet＋probiotics( soybean meal inoculated with Streptococcus thermophilus, Lactobacillus acidophilus, Aspergillus awamori, Bifidobacterium thermophilum, Saccharomyces cerevisiae, Corynebacterium acetoglutamicum, Bacillus licheniformis, Aspergillus oryzae) and probiotics B which contained basal diet＋probiotics ( soybean meal inoculated with Streptococcus thermophilus, Lactobacillus acidophilus Aspergillus awamori, Bifidobacterium thermophilum, Saccharomyces cerevisiae, Aspergillus niger, Trichoderma koningi). The results demonstrated that the probiotics B group had significantly improved the FE (feed/gain) and phosphorous utilization than others group (P < 0.05), and was significantly higher than control group in digestibility of GE and CP (P < 0.05). Furthermore, the probiotics A group had a greater crude fiber digestibility than other groups (P < 0.05). Diet contained probiotics could decrease the amount of E. coli. in feces (P < 0.05). In serum lipids levels, probiotics A group had the lowest cholesterol concentration, and had lower LDL-C concentration compared with control group (P < 0.05). In immune responses, after HC vaccine injection, the HC specific antibody titer increased significantly in the second week for pigs fed with probiotics B diet. In conclusion, the results indicated that probiotics supplementation had beneficial effect on growing-finishing pigs. Nevertheless, the results showed that these effects will be variable if supplemented with different probiotics assortment.
