The Effect of Soybean Residue Mixed Silage Feed on the Growth Performance and Meat Quality of Ecological Native Chickens
To analyze the effect of soybean residue mixed silage feed on the growth performance and meat quality of ecological local chickens.Sixty ecological local chickens from a chicken farm in Loudi City,Hu'nan Province were selected as experimental subjects.They were randomly divided into a control group and an experimental group,with 5 replicates in each group and 6 local chickens in each replicate.The significant differences in the effects of soybean residue mixed silage feed on the growth performance and meat quality of ecological local chickens were compared and analyzed.The average daily weight gain of ecological chickens in the experimental group of mixed soybean residue silage feed was significantly higher than that of the control group(P＜0.05),and the feed to weight ratio was significantly lower than that of the control group(P＜0.05).The average daily feed intake was slightly higher than that of the control group,but the difference was not significant(P＞0.05);The slaughter rate,shear force,and hydraulic capacity of the ecological broilers in the experimental group of soybean residue mixed silage feed were significantly higher than those in the control group(P＜0.05),while there were no significant differences in leg muscle rate,chest muscle rate,meat color,fat content,pH,and other indicators between the experimental group and the control group(P＞0.05).Soybean residue mixed silage feed can significantly improve the growth performance and meat quality of ecological chickens,which provides a reference basis for the nutritional selection and combination of feed for healthy breeding of ecological chickens in this region.
