Abstract

This experiment was conducted to investigate the effects of compound probiotics on growth performance, slaughter performance, immune organ index and serum biochemical parameters of squabs. Seventy-two pairs of breeding pigeons and 144 squabs were selected and randomly divided into 4 groups with 6 replicates per group and 3 pairs of breeding pigeons and 6 squabs per replicate. In fed the same basal diet at the same time, the control group was fed the health care sand, groups Ⅰ, Ⅱ and Ⅲ were fed the health care sand with compound probiotics Ⅰ (Lactobacillus acidophilus+Bifidobacterium lactis), compound probiotics Ⅱ (Bifidobacterium lactis+Enterococcus faecalis) and compound probiotics Ⅲ (Lactobacillus acidophilus+Enterococcus faecalis), resperctively. The experiment lasted for 28 days. The results showed as follows: compared with the control group, 1) in the aspect of growth performance, group Ⅱ significantly increased the body weight at 28 days of age and the average daily gain of squabs (P<0.05). 2) In the aspect of slaughter performance, group Ⅱ significantly increased the slaughter rate, semi-eviscerated rate and eviscerated rate of squabs (P<0.05), group Ⅰ and group Ⅲ significantly reduced the abdominal fat rate of squabs (P<0.05)). 3) In the aspect of immune function, group Ⅱ significantly increased thymus index of squabs (P<0.05). 4) In the aspect of serum biochemical index, group Ⅰ and group Ⅲ significantly reduced the content of total protein and globulin in serum of squabs (P<0.05), group Ⅰ, group Ⅱ and group Ⅲ significantly reduced the serum creatinine content of squabs (P<0.05), group Ⅱ and group Ⅲ significantly reduced the serum triglycerides content of squabs (P<0.05), group Ⅱ significantly increased the serum high density lipoprotein content of squabs (P<0.05). In summary, compound probiotics added in the health care sand can improve the growth performance, slaughter performance, immune organ index and serum biochemical index of squabs.
