ZHENG Wen-min et al
This experiment was conducted to study the effect of alfalfa diets on production performance, slaughter quality of broiler.22-day-old AA broilers were divided into four treatments and four replicates in each feeding. The treatment Ⅰ,Ⅱ,Ⅲ,Ⅳwere fed 0%,2%,4%,6% alfalfa meal. The results showed:The broiler average daily gain and feed conversion of the alfalfa meal diets were lower than treatment Ⅰ,daily feed intake of the alfalfa meal diets were increased.there was no significant difference between each treatment(P0.05).Color difference were significant between treatment Ⅲ,Ⅳ,Ⅴ withⅠ(P 0.01),skin and shank color were deeper in alfalfa meal diet compared with treatmentⅠ.Abdomen fat ratio was increased with the alfalfa meal adding quantity increasing,there were no significant difference between each treatment(P0.05).There was no significant difference in slaughter quality between each treatment(P0.05). Alfalfa is fine nature color feed additives.There are no significant differences on production performance and slaughter quality.
