概括

使用克洛米芬酸盐 (CC) 和Altrenogest的新协议有效地为胚胎移植准备了非循环受体母马. 与传统方法相比,这种马匹育种的进步导致了更高的怀孕率.

科学领域:

生殖生物学生殖生物学
兽医医学兽医医学兽医医学
马科的科学马科的科学

背景情况:

胚胎移植 (ET) 对于马匹育种计划中的遗传改进至关重要.
有效的接受母马准备对于成功的ET至关重要,但对非循环母马的协议具有挑战性.
目前准备受体母马的方法往往需要优化以提高效率.

研究的目的:

评估一种用于准备非循环受体母马进行胚胎移植的新方案.
评估克洛米芬酸盐 (CC) 和口服Altrenogest在同步非循环马匹中的疗效.
为了比较使用新方案治疗的母马与周期性对照对象的怀孕率.

主要方法:

72只本地品种母马被分为两组:60只非周期性母马 (第一组) 和12只周期性对照 (第二组).
第1组接受了口服克洛米芬酸盐 (CC) 4天,然后口服阿尔特雷诺杰斯特6天.
超声波监测了子宫回声质和怀孕,并评估了血清雌激醇和孕激素水平.

主要成果:

用CC和Altrenogest (1组) 治疗的母马的血清孕激素度明显高于对照组 (P < 0.001).
在期期间,雌激醇度在各组之间没有显著差异 (P > 0.05).
第1组与第2组相比 (66.6%) 实现了更高的怀孕率 (83.3%).

结论:

使用口服克洛米芬酸盐 (CC) 和Altrenogest的新协议对准备非循环受体母马有效.
该协议提供了一种可行的解决方案,用于提高非周期性母马的胚胎移植成功率.
这些发现支持使用CC和Altrenogest来增强马匹育种技术.

In Vitro Fertilization

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...
