摘 要：
为制定肉种鸭在育成期合适的限制饲养方法,试验选取10周龄的樱桃谷肉种鸭母鸭800只,随机分成4组(T1～T4),分别以4种不同的限饲方式进行限饲至20周龄。测定不同限饲方式对樱桃谷肉种鸭育成期生长性能、产蛋期产蛋性能和孵化水平的影响。通过综合比较,从中筛选出较为理想的樱桃谷肉种鸭的限饲方式。结果显示:(1)生长性能:樱桃谷肉种鸭20周龄的平均体重以T3、T4组较好,且其整个时期的生长曲线与樱桃谷肉种鸭的标准体重曲线相接近,而T2组严重偏离樱桃谷肉种鸭的标准体重曲线;(2)产蛋性能:T3、T4组开产较早,50周龄入舍鸭的平均产蛋量最高,分别为140.20枚/只、140.60枚/只,两组差异不显著(P>0.05),其他组均差异极显著(P<0.01);T3、T4组产蛋高峰期的持续时间也比其他两组长;(3)孵化指标:限饲各组的种蛋合格率、受精率、孵化率均差异不显著(P>0.05);(4)经济成本核算:据成本计算以T4组平均每只肉种鸭限饲时投入的饲料成本最低。综上表明:T4组为樱桃谷肉种鸭育成期最为理想的限饲方式。

摘 要：
To make the restricted feeding method for the meat-type breeder ducks, a total of 800 cherry valley female breeder ducks at 10 week-old were randomly divided into four groups (T1 to T4 ) with each group included 200 individuals, and then these ducks were fed restrictedly to 20 week-old by four different ways. The effect of growing performance, egg-laying performance and hatching level were detected by four different restricted ways. The ideal restricted way was screened by comprehensive comparison. The results showed that the average weight at 20 weeks age of T3 and T4 were better, and the whole period growth curves of T3 and T4 was close to the cherry valley duck standard weight curve, whole the growth curve of T2 was serious deviation from cherry valley duck standard weight curve; T3 and T4 group had earlier first laying, and the highest average egg production at 50 week age, which were 140.2 and 140.6 respectively, and there was no significant differences (P>0.05) in egg production between T3 and T4 was, and whole there were significant differences (P<0.01) between them and other groups and laying peak period of T 3 and T 4 had more longer duration than the other two groups; there were no significant differences (P>0.05) in Feeding eggs pass rate, fertility rate, andhatching rate among four groups; According to calculating the economic benefits, T4 group had lowest feed costs. Thus, the most ideal feed restricted way for cherry valley duck was T4 group.
