【摘要】：本试验旨在探索添加大豆黄酮后对肉种鸡产蛋和繁殖性能的影响。选取43周龄体况接近一致(体重、产蛋率)的肉种鸡S2系母鸡240只,随机分成4组,每组6个重复,每个重复10只:选取1组作为对照组,饲喂无大豆黄酮的基础饲粮,其余3组分别在基础饲粮基础上添加5、10、20 mg/kg大豆黄酮。再挑选20只强健的S2系公鸡采集精液,混精对试验鸡进行人工授精,试验期为15周。结果表明:与对照组相比,1)添加大豆黄酮对S2系母鸡体增重、采食量及死亡率无显著影响(P0.05)。2)添加大豆黄酮后能显著提高产蛋率(P0.05),其中10 mg/kg组产蛋率提高了4.1%(P0.05),日产蛋量提高了3.5%(P0.05),为3组最佳。5、10 mg/kg组料蛋比分别降低了8.0%和11.2%(P0.05)。3)10 mg/kg组受精率、孵化率和健雏率分别提高了13.1%、20.5%和5.8%(P0.05)。由此可见,饲粮中添加大豆黄酮能显著影响肉种鸡产蛋和繁殖性能,其中10 mg/kg组综合效果最佳。
[Abstract]:The purpose of this experiment was to explore the effect of daidzein on laying and breeding performance of broilers. 240 S2 hens of 43-week-old were randomly divided into 4 groups, 6 replicates in each group and 10 in each group: group 1 was used as control group and fed basic diet without daidzein. The other three groups were supplemented with daidzein for 20 mg/kg on the basis of basal diet. Semen was collected from 20 sturdy S2 roosters, and artificial insemination was carried out for 15 weeks. The results showed that: 1) addition of daidzein had no significant effect on body weight gain, feed intake and mortality of S2 line hens (P0.05). The laying rate of 10 mg/kg groups increased by 4.1% (P0.05), and the daily egg production increased by 3.5% (P0.05). The fed-to-egg ratio of the three groups was decreased by 8.0% and 11.2% (P0.05), the hatching rate and the brooding rate of the 10 mg/kg group were increased by 13.1% and 5.8% respectively (P0.05). It can be seen that the addition of daidzein in diet can significantly affect the laying and reproductive performance of broilers, and the comprehensive effect of 10 mg/kg group is the best.
