- 动物繁殖 动物繁殖
背景情况:
- 几内亚猪 (Cavia porcellus) 在秘鲁具有经济意义,提供有价值的蛋白质来源.
- 提高几内亚猪的繁殖效率对于商业养殖至关重要,以确保统一的体重,年龄和 litter 尺寸.
研究的目的:
- 评估克洛普醇对秘鲁海豚雌性诱导的作用.
- 为了确定最佳剂量和男性刺激对雌性开始,持续时间和强度的影响.
主要方法:
- 128只8-12个月龄的海豚 (120只雌性,8只雄性) 被分为两组,接受不同剂量的克洛普罗醇 (0,0.20,0.25,0.30毫克/动物),有或没有雄性刺激.
- 通过观察行为迹象来评估雌激素,并记录了发病,持续时间和强度.
- 克洛普醇是通过肌肉内注射的.
主要成果:
- 雌激素发作发生在大约2天后.
- 最高剂量 (0.30毫克/动物) 与雄性刺激相结合,在46.9小时产生了最早的雌激.
- 与对照组相比,克洛普罗醇的使用显著减少了期持续时间 (p < .05) 和增加了期强度 (p < .01).
结论:
- 克洛普罗醇的使用对秘鲁海豚的快速雌性诱导是有效的.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
