Effects of cottonseed meal fermentation by Bacillus subtilis on nutrient metabolic rates and production per-formance of yellow broilers
ABSTRACT:The effects of cottonseed meal(0% ,2% ,5% ,8% ) fermentation by Bacillus subtilis on nutrient metabolic rates and production performance of 1 day old yellow broilers were studied .Compared with the control group ,the apparent digestibility of crude protein ,calcium and phosphorus of the test groups were significantly increased ,which of 8% cottonseed meal group was the highest ;crude fat digestibility decreased significantly ,the average daily gain and food conversion ratio were significantly increased ;5% cottonseed meal group had the highest daily gain weight and food conversion ratio .Adding 5% cottonseed meal fermentation by Bacillus subtilis into the diet showed good effect .
