Question
Explain how and why controlled breeding experiment is carried out in cattle?
✓
Answer
- Controlled Breeding Techniques: The breeding of animals using controlled techniques is another major approach to animal breeding. It includes Artificial Insemination (AI) and Multiple Ovulation Embryo Transfer (MOET).
- Artificial Insemination: It is a method in which the semen collected from a superior male parent is injected into the reproductive tract of the selected female parent by the breeder. The success rate of artificial insemination is fairly low, even then it is carried out because of the following advantages.
- The semen collected can be used immediately or can be stored in frozen form for later use.
- The semen from a desired breed can be easily transported in the frozen form to distant places, where the selected females are present and thus can be used for impregnating the females on a large scale.
- It helps in overcoming several problems of normal mating.
- Multiple Ovulation Embryo Transfer Technology (MOET): It is a programme employed for the herd improvement. A herd is a group of animals that live together or are kept together as livestock like cattle, sheep, rabbit, buffaloes, mares, etc.
