- Abstract
This study was conducted to investigate the effects of Lactobacillus acidophilus, Enterococcus faecium, Bacillus subtilis and Bacillus lichenifor⁃ mis compound probiotics on serum biochemistry, cecal short-chain fatty acids (SCFAs) and microbiota of Shaoxing ducks at different supplemental levels. A total of 1 200 1-day-old Shaoxing ducks with similar body weight were randomly divided into 4 groups with 5 replicates per group and 60 ducks per replicate. Piglets in control group were fed a basal diet; Group A was fed the basal diet supplemented with 100 mg/kg compound probiotics; Group B was fed the basal diet supplemented with 200 mg/kg compound probiotics; Group C was fed the basal diet supplemented with 300 mg/kg compound probiotics. The pre-feeding period lasted for 3 days, and the normal feeding period lasted for 30 days. The results showed as follows: ① compared with the control group, the average daily gain (ADG) and average daily intake (ADFI) of the groups supplemented with compound probiotics had a numerical trend of increasing (P>0.05); the ratio of feed to gain in complex probiotics groups was significantly decreased (P<0.05), and the reduction ratio in group B was 4.2%. ② Compared with the control group, there were no significant differences in serum total protein, albumin, globulin, alanine aminotransferase and aspartate aminotransferase in group A, B and C (P> 0.05); Serum IgM and IgA were significantly increased (P<0.01), while serum IgG content was not significantly different (P>0.05). ③ Compared with the control group, the acetic acid content in cecum of group A, B and C was significantly increased (P<0.05), but the propionic acid and butyric acid contents in cecum were not significantly different (P>0.05), and the supplemental dose in the combined diet was 100- 200 mg/kg.
