Study Notes
Agriculture and Livelihood
- Agriculture is a major source of livelihood for many people
- Food products (cereals, vegetables, fruits, spices) come from plants
- Milk, eggs, and meat come from animals
Selective Breeding
- Farmers breed animals and horticulturists cultivate crops with desired characteristics
- Selective breeding is a process of breeding plants and animals to obtain specific traits
- Examples of selective breeding include: Saddle black pigs (high meat yield)
Hybridisation
- Combining two different varieties to produce a new variety
- The new variety (hybrid) often has better qualities (yield, taste, nutritional value, tolerance to conditions like heat, cold, drought, disease)
- Examples:
- Yak X Cow = Yakow/Dzo (stronger, used as pack animals)
- Jersey bull X Cow = Jersey (high milk yield)
- Horse X Donkey = Mule (stronger)
