摘要
用29～36周龄海赛克斯(褐色)蛋用型父母代种公鸡112只、种母鸡1024只,研究了种公鸡日粮营养水平及其对繁殖性能的影响。上述试鸡,种母鸡饲用同一蛋鸡料,种公鸡则分别给饲下列4种日粮:1.高CP(17.5％),高AA(0.86％L_(Ys),0.63％SAA),高Ca(3.7％)日粮;2.CP(12.5％),低AA(0.55％L_(YS),0.45％SAA),高Ca(3.7％)日粮; 3.低CP(12.5％), 低AA(0.55％ L_(Ys), 0.45％SAA), 低Ca(1.0％)日粮;4,同3,仅更换维生素-微量元素综合预混料。结果:1.采用低CP、低AA、高Ca或低CP、低AA、低Ca日粮时,种公鸡的精液品质、种蛋受精率、孵化率等均无异于用高CP、高AA、高Ca日粮者(P>0.05);2.采用种公鸡专用维生素-微量元素综合预流料,入孵蛋孵化率提高3.35％,日饲用低CP、低AA、低Ca日粮的种公鸡体增重(29～36周龄)大于用高CP、高AA、高Ca日粮者(P<0.05),其36周龄体重较接近于品种标准。
120 breeder males and 1024 breeder females at 28-wk of age (Hisex Brown layi-ing type Parent flock) were divided into four treatments. All females were fed the Same ration. Breeder males were given four dietary treatments: The experiment yielded following results at 36 wk of age: (1) When breeder males were fed Low CP(12.5%), low AA(0.55%Lys, 0.45%SAA) , high Ca(3.70%) or low CP, low AA, low Ca(1.00%) diet, semen quality, fertility,and hatchablity were not different to that of birds using high CP(17.50%)high AA(0.86% lys, 0.63% SAA), high Ca(3.70%)ration(P>0.05). (2) With the special vitamin and mineral premix, the hatchability of hatching eggs increased 3.35%. (3) Body weight gain of breeder males on low CP, low AA, low Ca diet was higher than that of males using high CP, high AA, high Ca diet (P<0.05) . Their body weight at 36 wk of age was close to the breed standard.
