Overview of Animal Breeding and Selection
Animal husbandry involves the scientific management of animal livestock, including feeding, breeding, and disease control. To meet the increasing demand for milk, meat, and eggs, improvement in livestock quality is essential. This is largely achieved through selective breeding and hybridization.
1. Cattle Farming
Cattle husbandry is done for two main purposes: milk production (milch animals) and draught labor (draught animals) for agricultural tasks like tilling and carting.
- Milch Animals: Females kept for milk production.
- Draught Animals: Males used for farm labor.
2. Breed Improvement
Improving breeds aims to combine desirable traits from different varieties. The method most commonly used is cross-breeding (hybridization) between:
- Exotic (Foreign) Breeds: Such as Jersey and Brown Swiss, selected for long lactation periods.
- Indigenous (Local) Breeds: Such as Red Sindhi and Sahiwal, selected for excellent resistance to diseases.
The resulting cross-breeds possess both qualities: high milk yield and strong disease resistance.
3. Farm Management Ideas
Proper management is crucial for the health of livestock and the quality of produce:
- Shelter: Must be clean, dry, and well-ventilated to protect animals from rain, heat, and cold.
- Food: Requires roughage (fiber) and concentrates (proteins/nutrients). Balanced rations promote high yields.
- Disease Control: Regular vaccinations and hygiene prevent parasites (internal and external) and infectious diseases.
Comparison: Exotic vs. Local Breeds
| Feature | Exotic Breeds | Local Breeds |
|---|---|---|
| Examples | Jersey, Brown Swiss | Red Sindhi, Sahiwal |
| Primary Trait | Long lactation period | Disease resistance |
| Origin | Foreign (e.g., Europe) | Native (India) |
