Breeding Policy for Non-Descript Cattle
Breeding policy adopted for increasing milk production of non-descript cattle is-
- Inbreeding
- Crossbreeding — Correct Answer
- Grading up
- Line breeding
Explanation:
Correct Answer: Crossbreeding
For non-descript (non-defined) cattle with very poor genetic potential for milk production, the recommended and most effective breeding policy in India is Crossbreeding with superior exotic dairy breeds (Holstein-Friesian, Jersey, Brown Swiss).
Breeding Policies — When to Apply Each
| Policy | Best Applied for | Outcome |
|---|---|---|
| Crossbreeding | Non-descript cattle — to rapidly improve milk production | Infuses exotic dairy genes + exploits heterosis |
| Grading up | Non-descript cattle — when aim is to eventually obtain pure exotic breed | Pure breed obtained after 7–8 generations |
| Selective breeding | Well-defined indigenous breeds (especially buffalo) | Improves within breed without exotic crossing |
| Inbreeding | Developing uniform inbred lines (pigs, poultry) | Homozygosity → prepotency → inbred lines for crossing |
