Importance Of Artificial Insemination In Dairy Animals

As the name suggests, Artificial insemination (AI) is a technique in which sperm is collected from the male/bulls, processed, stored and manually introduced into the female reproductive tract at appropriate time for the purpose of conception. AI has become one of the most imperative techniques for the genetic improvement of farm animals since preferably the semen from genetically superior sires/males are used to inseminate the female animals artificially. It has been most extensively used for breeding dairy cattle and buffaloes. AI is the tool that possesses the potential of economic and rapid diffusion of elite males to a large number of females in a short duration of time over a large geographical area.

Artificial insemination is not merely a novel method of bringing about impregnation in females. Instead, it is a powerful tool mostly employed for livestock improvement. In artificial insemination, the germplasm of the bulls of superior quality can be effectively utilized with the least regard for their location in faraway places. By adoption of artificial insemination, there would be considerable reduction in both genital and non-genital diseases in the farm stock.

Advantages of Artificial Insemination Over Natural Mating-:

Artificial insemination (AI) is one of the most efficient tools accessible to dairy farmers to improve productivity and profitability of dairy enterprise. In artificial insemination the bulls of superior quality can be efficiently exploited with the least concern for their location in faraway places. There are a lot of advantages of AI over natural services with bulls. They are as follows:-

• Boosts efficiency of bull usage: During natural mating, a bull will donate much more semen than is theoretically needed to make a pregnancy. On the other hand, collected semen can be diluted and extended to make hundreds of semen doses from a single ejaculate which can be easily carried one place to another, promoting multiple inseminations in females in different geographical locations and semen can be stored for long periods of time
• Cost Effectiveness: No necessity of maintenance of breeding bulls. Hence, the expenditure on maintenance of breeding bull is saved.
• Checks disease transmission: Natural mating allows the transmission of venereal diseases between males and females. On the other hand, for AI, semen is regularly tested for its quality, possible infections hence allows checking of the spread of certain venereal diseases. Eg: contagious abortion, vibriosis.
• Promotes Breeding Efficiency: By routine examination of semen after collection and frequent checking on fertility make early detection of inferior bulls and better breeding efficiency is warranted.
• The progeny testing can be employed at an early age.
• The semen of an elite bull can be used even after the death of that sire.
• It makes possible the mating of animals with great variations in body size with no injury to either of the animal.
• It is useful to inseminate the cows denying to stand or accept the bulls at the time of oestrum.
• Useful in maintaining the perfect breeding and calving records.
• Artificial Insemination enhances the rate of conception.
• Artificial Insemination allows the use of old, heavy and injured sires.
• Artificial Insemination when linked to oestrous synchronization programme, can promote a more consistent, uniform calf crop production.

Dairy farmers have numerous arguments against Artificial Insemination. In general, an AI program would need more intensive management of the herd like a sound nutrition program (cows in good body condition), good record keeping in the farm, an efficient herd health program, precise heat detection and a well-trained AI technician. Poor management in one or more of these fields might result in poorer success rates. Few major drawbacks of AI are mentioned below:

• Requires well-trained personnel and special tools.
• Takes more time than natural services.
• The AI operator needs to have the knowledge of the structure and function of reproduction in the dairy animals.
• Improper cleanliness of instruments and unhygienic conditions may lead to declined conception.
• If the bull is not appropriately examined, the spreading of venereal diseases will be increased.

Even though AI has few shortcomings, still it is the need of the hour for our Indian farmers to improve the breed of their dairy animals to increase their income. ABS India, SAG are the companies which are providing best quality semen with proven track records on a very economic price and life long support to farmers. We hope that with right knowledge and proper management , AI will break the myths among the farmer fraternity and more and more farmers will use this technique for breed improvement for their dairy animals.
