Animal husbandry plays a crucial role in the agricultural sector for several reasons:
1. Livestock production: It encompasses the rearing of various animals like cattle, sheep, goats, poultry, etc., for their products such as milk, meat, eggs, wool, etc. These products contribute significantly to the economy and the food supply chain.
2. Nutrient recycling: Animals play a vital role in the recycling of nutrients. They convert crop residues, agricultural by-products, and organic waste into valuable manure, which enhances soil fertility and promotes sustainable agriculture.
3. Diversification of income: Animal husbandry provides additional income sources for farmers. They can sell livestock products, breed animals for sale, or engage in animal-related services like veterinary care, animal transportation, etc.
4. Rural employment: Animal husbandry generates employment opportunities in rural areas. It requires skilled workers for various tasks such as animal care, breeding, feeding, veterinary services, and marketing, thereby reducing unemployment and migration.

Livestock can be used for weed control, pest management, and land preparation, reducing the reliance on chemical inputs and promoting sustainable agricultural practices.
