溴隐亭和克罗米芬对乌鸡醒抱及醒抱后蛋品质量的影响

Study on the Effects of Bromocriptine Mesilate and Clomifene Citrate on Rivival from Incubation and Eggs' Quality of Silki Hens

研究溴隐亭和克罗米芬对就巢鸡就巢时间和产蛋性能的影响以及恢复产蛋后对蛋品质量的影响,试验将36只抱窝的丝羽乌鸡随机分成3组,Ⅰ组为对照组,Ⅱ组第1～2天每只鸡每天口服溴隐亭1.25mg,第3～7天每只鸡每天口服克罗米芬12.5mg;Ⅲ组第1～2天每只鸡每天口服溴隐亭0.625mg,第3～4天每只鸡每天口服溴隐亭1.25mg,第5～6天每只鸡每天口服克罗米芬25mg,第7天每只鸡口服克罗米芬12.5mg。研究。试验结果表明,Ⅰ组鸡只平均抱窝时间最长为8.58d,Ⅱ组为6.67d,Ⅲ组为6.83d;处理后一个月内的平均产蛋率分别为37.72%、59.65%和53.51%,Ⅱ组和Ⅲ组的产蛋率显著高于对照组(P<0.05);3个组的平均蛋重分别为43.86g、44.65g和44.16g,蛋形指数分别为1.306、1.312和1.323,蛋壳厚度分别为0.327mm、0.338mm和0.332mm,溴隐亭和克罗米芬对后3项指标的作用效果差异不显著(P>0.05)。

The effects of bromocriptine mesilate and clomifene citrate on broody days, reproductive pertormance, eggs＇ quality of broodying silki hens were studied in the paper. 36 broodying silki hens were alloted randomly to 3 groups： hens of trail 1 were given bromocriptine mesilate per os 2 days （1.25mg/day/hes）, then clomifene citrate 5 days （12.5mg/day/hen）; hens of trial 2 were given bromocriptine mesilate 4 days, then given clomifene citrate 3 days. The results showed that the average brooding days of trial 1 was 6.67 days, that of trial 2 was 6.83 days, and that of control group was 8.58 days. Average lay rate within 30 days were 37.72%（control group）, 59.65%（trial 1）, 53.51%（trial 2） respectively, and trial group was obviously higher than control group （P〈0.05）. Average egg size of control group, trial 1, trial 2 were 43.86g, 44.65g, 44.16g respectively, and average egg shape index were 1.306, 1.312, 1.323 respectively, and average egg shell thickness were 0.327mm, 0.338mm, 0.332mm respectively. The effects of bromocriptine mesilate and clomifene citrate on egg size, egg shape, egg shell thickness were not obvious（P〉0.05）.
