摘要:
将3 600只海兰褐壳蛋鸡(300日龄)随机分为试验组和对照组,每组6个重复,每个重复300只。试验组饲喂添加苜草素的基础日粮;对照组只喂基础日粮。结果:(1)试验组与对照组的蛋重、产蛋率、死亡率分别为58.15 g和52.06 g、78.8%和74.18%、1.03%和1.09%,均差异显著(P0.05);(2)试验组与对照组蛋鸡日耗料量分别为102.64 g和105.06 g,有降低趋势,但差异不显著(P0.05);(3)试验组与对照组的蛋壳厚度、哈氏单位分别为0.365 mm和0.352 mm,89.50和80.52,均差异显著(P0.05);(4)试验组与对照组血清中胆固醇、雌二醇、钙的含量分别为3.20 mmol·L-1和3.82 mmol·L-1,25.81 ng·m-1 1和32.23 ng·ml-1,7.141mmol·L-1和6.306 mmol·L-1,均差异显著(P0.05);(5)试验组与对照组血清总蛋白、白蛋白、球蛋白、葡萄糖、甘油三酯、高密度脂蛋白含量差异不显著(P0.05)。结果表明苜草素对提高蛋鸡的生产性能,改善蛋的品质,降低死亡率和蛋料比有一定的促进作用。

Abstract:
The effects of Mucaosu(alfalfa extracts) on the laying performances and serum parameters in laying hens were studied.3600 Hy-line brown laying hens(300 days old) were randomly divided into treatment group fed with basic diet containing Mucaosu and control group fed with basic diet only,each group had six replication.The results showed as follows:(1) The egg size,laying rate,death rate in treatment and control were 58.15 g and 52.06 g,78.8% and 74.18%,1.03% and 1.09%,respectively,and their differences were significant(P0.05).(2) The daily feed consumption of each hen were 102.64 g in treatment and 105.06 g in control,and there was no significant difference(P0.05).(3) The shell thickness,the Haugh unit in treatment and control were 0.365 mm and 0.352 mm,89.50 and 80.52,respectively,and the differences were significant(P0.05).(4) The cholesterol,estradiol,calcium of serum in treatment and control were 3.20 mmol·L-1 and 3.82 mmol·L-1,25.81 ng·ml-1 and 32.23 ng·ml-1,7.141 mmol·L-1 and 6.306 mmol·L-1,respectively,the differences were significant(P0.05).There were no significant diffierence in TP,AIB,GLB,GLU,TG,HDL-C in serum between two grougs(P0.05).It was concluded that alfalfa extract adding to diet improved the performances of the laying performance and quality of eggs,increased healthy status of laying hens.
