Answer :
The two common reasons artificial insemination fails are improper heat detection and poor insemination technique (A, C).
1. Improper heat detection: Successful artificial insemination relies heavily on accurately detecting when a female animal is in heat (estrus). If heat detection is inaccurate or missed altogether, insemination may occur at the wrong time in the animal's reproductive cycle, reducing the likelihood of conception. This can lead to failed insemination attempts.
2. Poor insemination technique: The process of artificial insemination requires skill and precision. If the insemination technique is subpar, it can result in improper placement of the semen, inadequate semen deposition, or damage to the reproductive tract of the female animal. These factors can significantly reduce the chances of successful fertilization and conception, leading to failed insemination.
