This experiment was conducted on study the effects of compound microecological preparation (CMP) on growth performance
immune function
antioxidation level and intestinal microflora of yellow-feathers black-bones chickens. Three hundred healthy 1-day-old chickens were randomly assigned to 5 dietary treatments (probiotics 1
probiotics 2
probiotics 2 + Chinese herbal medicine + maggot powder
Chinese herbal medicine + maggot powder and control group). The results were shown as follows: ① CMP increased ADG and F/G significantly
but had no significant effects on ADFI. ② Compared with the control group
CMP stimulated the development of organs like thymus
spleen and bursa of fabricius significantly and increased the content of IgG by 46%
the activity of LZM by 69%. ③ CMP enhanced the levels of antioxidation by increasing the activity of GSH-PX
CAT and SOD
the effect is more pronounced in the liver. ④ CMP reduced the intestinal pH distinctly and improved the probiotics proportion of intestinal microflora by 20.2%.
