Reproductive and Herd Terminology
Match the column:
| TABLE-I | TABLE-II |
|---|---|
| 1. Generation interval | (a) Interval from conception to calving |
| 2. Calving interval | (b) Average milk production of a herd |
| 3. Calving index | (c) Average age of parents when their offspring are born |
| 4. Gestation period | (d) Interval between two successive calving of an animal |
| 5. Herd average | (e) Average interval between two successive calving of a herd |
- 1-c, 2-d, 3-e, 4-a, 5-b — Correct Answer
- 1-c, 2-e, 3-d, 4-a, 5-b
- 1-a, 2-d, 3-e, 4-c, 5-b
- 1-c, 2-d, 3-e, 4-b, 5-a
Explanation:
Correct Answer: 1-c, 2-d, 3-e, 4-a, 5-b
Important reproductive and herd terminologies:
- Generation interval → Average age of parents when their offspring are born — cattle (4 yr), buffalo (4.5 yr), pig (2.5 yr).
- Calving interval → Interval between two successive calvings of an individual animal — ideally 365 days.
- Calving index → Average interval between two successive calvings of a HERD — a herd-level measure of reproductive efficiency.
- Gestation period → Interval from conception to calving — cattle 283 days, buffalo 310 days.
- Herd average → Average milk production of a herd.
Why Other Options Are Wrong
- Option B swaps Calving interval (individual) with Calving index (herd).
- Option C swaps Generation interval with Gestation period.
- Option D swaps Gestation period with Herd average.
