Species Utilizing Commercial Inbred Lines
Inbreeding is used for commercial production of inbred lines in-
- Cattle, buffalo
- Pig & poultry — Correct Answer
- Pig & buffalo
- Poultry & cattle
Explanation:
Correct Answer: Pig & poultry
Developing inbred lines is economically viable only in pigs and poultry due to their short generation intervals, high litter/clutch sizes, and relatively low per-animal cost. In large ruminants (cattle, buffalo), it is economically and practically unfeasible.
Why Inbred Lines are Commercially Used in Pigs & Poultry
| Feature | Pigs & Poultry | Cattle & Buffalo |
|---|---|---|
| Generation interval | Short (6 months–1 year) | Long (3–4 years) |
| Offspring per female/year | High (10–15 piglets; 200+ eggs) | Low (1 calf/year) |
| Per-animal value | Relatively low | Very high |
| Inbreeding depression impact | Manageable economically | Catastrophic economically |
| Commercial inbred lines | Yes — widely used | No — unfeasible |
Connection to Nucleus Breeding
- CNBS (Closed NBS) is mainly used in pigs & poultry — compatible with inbred line development
- ONBS is used in cattle, buffalo & sheep — where inbred lines are not practical
