- 在不同的实验环境中,将PGF治疗与布塞雷林酸盐和对照组进行比较.
主要方法:
- 实验I:断奶母猪在不同时间点 (0-2小时或24-26小时后雌激素检测) 接受PGF或没有激素 (控制).
- 实验II:在断奶后72小时内没有表现出雌性体的断奶母猪接受了布塞林酸盐,PGF,一种组合,或没有激素 (控制).
- 排卵时间和 litter 大小被监测和统计分析.
主要成果:
- 在实验I中,PGF的使用并没有显著改变排卵间隔或排卵母猪的比例.
- 在实验II中,与PGF和对照组相比,布塞雷林酸缩短了排卵的间隔.

1.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
