Often times, Ruminant farmers always want to know which method is better between Natural Mating and Artificial Insemination. Well, if the semen to be used in Artificial Insemination are well preserved and handled, it could be better because a single ejaculate can be used to mate as much as 20 or more females while in natural mating, it is a male to a female at a time. Also the fertility rate is higher with Artificial Insemination (A.I) than with Natural Mating because in Artificial Insemination (A.I) one is also 100% sure that the semen has been introduced into the proper place whereas in Natural Mating, it is possible for mating to occur without fertilization because the semen may be having problem or may not have been introduced into the proper place in the female.
Moreover, Artificial Insemination (A.I) could be economical when the number of female that can be fertilized with a single ejaculate is considered. However, when the details involved in Artificial Insemination (A.I) like preserving the semen and expertise in introducing the semen is considered, then, natural mating may be preferred especially by those who could not afford the cost of transportation of semen and those of preserving them.
