Expected Yield Increase Through Crossbreeding
Grading up & cross breeding programs are expected to increase milk production in cattle-
- More than 5% Annually — Correct Answer
- 2% Annually
- 1% Annually
- None
Explanation:
Correct Answer: More than 5% Annually
Grading up and crossbreeding programs for non-descript cattle are expected to increase milk production by more than 5% annually, because the base production of non-descript cattle is very low and the introduction of superior genetics has a dramatic effect.
Genetic Gain Comparison by Programme
| Breeding Programme | Expected Genetic Gain |
|---|---|
| Crossbreeding / Grading up of non-descript cattle | >5% annually |
| Selective breeding within zebu (organized herds) | ~1% per year |
| Selective breeding in farmer herds | ~10% initially (from low base) |
