蛋白质水平对育成期蛋鸡啄羽和其它行为的影响

摘要

According to experimental design,300 Hailan layers were randomly divided into 60 groups,each group including 5 chickens.They were feeding under three different protein levels(14%,17% and 19%).During 9 to 11 weeks,through observation the behavior of feather pecking,feeding,groveling,grooming,foraging,drinking,standing and walking,the results showed that the protein level had a significant effect on feather pecking and groveling behavior (P<0.05).With the increasing of protein level,the groveling and grooming behavior gradually increased,but feather pecking,feeding and foraging behavior gradually decreased.%选择海兰白羽蛋鸡雏300只,按照试验设计随机分60组,每组5只鸡.分别饲喂14%、17%和19%三个不同蛋白质水平日粮,观察鸡只第9周~11周的啄羽行为、采食行为、趴卧行为、修饰行为、寻食行为、饮水行为、站立行为和走动行为.研究发现,蛋白质水平对育成期蛋鸡啄羽和趴卧行为的影响显著(P<0.05).随着蛋白质水平的提高,育成期蛋鸡的趴卧和修饰行为逐渐增加;啄羽、采食和寻食行为逐渐减少.
