👶Animal Husbandry — Definition, Classification, Livestock Population and Economic Significance

What is Animal Husbandry?

• The term husbandry derives from the word “husband” which means ‘one who takes care’. This concept highlights the responsibility humans have in nurturing and managing livestock for productive purposes. When it incorporates the study of proper utilisation of economically important domestic animals, it is called Livestock Management.
• Domesticated: Those that are of use at home and are easily bred and looked after by humans. Over thousands of years, humans have selectively bred animals for desirable traits such as milk yield, meat quality, and temperament. Common domesticated animals are dog, horse, cow, sheep, buffalo, fowl etc.

Animals We Will Study in This Lesson

This lesson focuses on the six most economically important domesticated species in India — the ones that dominate livestock censuses, competitive exam questions, and farm income data:

Cattle · Buffalo · Sheep · Goat · Swine · Chicken

These six were chosen because they collectively account for the vast majority of India’s livestock population (535 million), contribute to GVA, exports, and rural livelihoods, and are the primary subjects of IBPS AFO, NABARD, and RRB-SO questions.

Classification of These Animals

They can also be classified by digestive system:

Significance of Livestock and Poultry in Indian Economy

• Agricultural is the back bone of Indian Economy and within agriculture, livestock plays an importance role in providing sustainable income to farmers throughout the year. Unlike crop farming, which is seasonal, livestock generates income year-round through milk, eggs, meat, and other products.
• Livestock farming is an integral part of crop farming and contributes substantially to household nutritional security and poverty alleviation through increased household income. For millions of rural households, livestock serves as a supplementary income source that cushions against the risks of crop failure.
• Dairy animals produce milk by converting the crop residues and by products from crops which otherwise would be wasted. Dairy sector contributes by way of cash income, draught power and manure. Livestock provides for human needs by way of
  • Food
  • Fibre
  • Fuel
  • Fertilizer
  • Skin
  • Traction
• It is a living bank providing flexible finance in time of emergencies and also serves as insurance against crop failure for survival. Farmers can sell animals when they face financial distress, making livestock a liquid asset in rural economies. If Agriculture is the foundation of our national economy, Animal husbandry constitutes the sheet anchor of agriculture. Family income from livestock and poultry acts as Bankers cheque.
• Effective utilization of labour — family labour is effectively utilized in animal husbandry. Women and children often contribute significantly to livestock rearing, making it an inclusive livelihood option.
• Soil fertility: organic manure — promotes and maintains soil fertility. Animal dung and urine are excellent sources of organic manure that improve soil structure, water-holding capacity, and nutrient content.

Nutrient content of manure (mg/g dry weight):

• Apart from manurial value biogas can be produced from livestock dung and poultry droppings. Biogas is a renewable energy source that can be used for cooking and lighting in rural areas, reducing dependence on firewood and fossil fuels.
• Cow produces 8 tonnes of farm yard manure per year and farm biomass and farm products which includes fodder, feed, edible weed, tree fodder, bund grass are better utilized — and converted to Edible products like — Milk, Meat and Egg.
• Inter relationship
  • Man-animal-plant interrelation is interdependent (one cannot survive without the help of other). Man not only depends on plants and animals for food but also for income and other needs. This symbiotic relationship forms the backbone of sustainable agriculture.
  • He co-ordinates activities of the crop and other husbandry by proper planning.
  
• The usage of draught animal power for ploughing of land. In many parts of India, especially among small and marginal farmers, bullocks remain the primary source of farm power.

India’s Livestock Position in the World

• India owns nearly 15% of the world livestock population, which is highest in the world with population of 535 million. This massive livestock population is both a strength and a challenge — it requires efficient management to maximize productivity.
• 70% of the livestock are owned by 67% of small and marginal farmers. This underscores the democratic nature of livestock ownership in India and its role in poverty alleviation.
• 76% of the milk is produced by weaker sections of society.
• India has nearly 57% of the world’s buffalo population (first rank), 16% of the cattle population (second rank), 20% of goat population (second rank) and 5% of sheep population (third rank) although India constitutes 2.4% of the world’s total land area. These figures highlight India’s extraordinary livestock density and the importance of efficient management practices.

• The contribution of livestock sector to the total Gross value added (GVA) is 5.5% of national GVA at current prices in 2023-24, accounting for 31% of total GVA of Agricultural and Allied Sector. This means nearly one-third of all agricultural economic output comes from livestock. (Agriculture, Forestry & Fishing together contribute 17.8% of national GVA.)
• Livestock GVA surged by 195% from 2014-15 to 2023-24, significantly outpacing the crop sector — reflecting the sector’s rapid transformation into a dominant pillar of agricultural income.
• It is estimated that about 18 million people are employed in the livestock sector in principal or subsidiary status. Total value of livestock product exports reached ₹66,249 crore in 2024-25, driven largely by bovine meat and edible offal.

Species Overview — Nomenclature and Basic Facts

Mature Body Weight and Ages of Different Species

Understanding the mature body weight and age milestones of different species is essential for planning feed requirements, breeding schedules, and marketing strategies.

---

Common Names in Livestock Population

Knowing the correct nomenclature — group names, gender-specific terms, birthing terms, and meat names — is fundamental for any student of animal husbandry and is frequently tested in competitive examinations.

Each species also has a unique scientific name and a fixed chromosome number (2n) — a key identifier in genetics and breeding science.

Body Temperature & Gestation Period of Domesticated Animals

Body temperature and gestation period are two clinically important parameters every livestock manager must know. Body temperature is a key health indicator — a fever is often the first sign of infection. Gestation period determines the breeding calendar and helps plan farm operations.

• Smaller the animal more is heat required to maintain the body metabolism. This is because smaller animals have a higher surface-area-to-body-weight ratio, causing them to lose heat more rapidly than larger animals.
• Body temperature may vary +1/-1 °C.

Problems in Indian Livestock Sector

• Though the cattle wealth is quite abundant in terms of population the production from these animals is very poor viz., 987 kgs per lactation whereas the world average is 2038 kgs per lactation. India’s per-animal productivity remains significantly below global standards, which presents both a challenge and an opportunity for improvement.
• The main reasons for this shortcoming are the abundant population of nondescript cows, chronic shortage of feed and fodder, poor nutritive value of the available feed and fodder, low fertility rates, destruction of grazing land, increasing human population and competition between animals and man for the available feed resources. Addressing these issues through genetic improvement, better nutrition, and scientific management is critical for boosting livestock productivity.

Solutions

• To satisfy the nutrient requirement for the huge population of livestock the options are:
  • To reduce the unproductive/ low productive animals. Culling of uneconomic animals and replacing them with improved breeds can significantly raise overall productivity.
  • Feeding of non-conventional feed stuffs — among these are the horticultural by products like agriculture by products, vegetable wastes and horticulture industrial wastes. Exploring alternative feed resources helps reduce competition with human food needs while lowering feed costs for farmers.
