2023年10月18日 · Artificial insemination (AI) is a widely used reproductive technique in cattle breeding. This article provides a comprehensive guide to the rectovaginal AI technique, including step-by-step instructions and tips for success. Learn how to perform AI safely and effectively to improve the genetic quality of your herd and increase conception rates.

Many producers of purebred and commercial beef cattle can profitably utilize artificial insemination (AI) on virgin heifers or on the cow herd or both. Success with artificial insemination requires attention to detail in all areas of herd management.

This article provides a review for those already familiar with AI technique, emphasizing reproductive anatomy, sanitation, and accuracy of semen deposition.

Recent development of estrus synchronization and fixed-time AI protocols allowed producers to breed more cows in a much shorter period of time and enhance the overall reproductive performance of the cowherd. Another advantage of AI protocols is that beef producers can assess and record the reproductive performance of individual cows.

Artificial insemination (AI) involves placing semen directly into the uterus. Embryo transfer involves transferring fertilised ova from a donor female to a recipient female who then rears the calf. Artificial insemination is used in both stud and commercial herds, whilst embryo transfer tends to be used mainly when breeding stud stock.

2023年7月19日 · Artificial insemination (AI) is a reproductive method that allows cattle producers to use sires that have superior genetics at an affordable price. Incorporating superior genetics into a herd more rapidly improves economically important attributes such as growth, maternal, and carcass traits and also decreases the incidence of dystocias ...

2021年3月1日 · Using the correct techniques when performing artificial insemination (AI) can help ensure success while minimizing risk of injury to the technician and the animal. Becoming proficient at performing AI takes adequate training, knowledge, and repetition.

Review the reproductive anatomy of the cow, heat detection, semen handling and the process to breed the cow to prevent common mistakes. First-time conception rate in virgin heifers should be 55% or more. For lactating cows, the goal should be a conception rate of 40% or more. Semen should be thawed at 95°F for 45 seconds.

2020年5月29日 · Artificial Insemination (AI) is an Assisted Reproductive Technology (ART) used worldwide to deposit stored semen directly into a cow or heifer’s uterus. It is a tool for improving reproductive performance and genetic quality of livestock.

Artificial insemination (AI) in cattle is a breeding technique where semen from a bull is manually placed into a cow’s reproductive tract. It’s a way to get cows pregnant without using a live bull on your ranch.
