Animal husbandry is the branch of agriculture concerned with the breeding, care, management, and use of domestic animals for various purposes, including food production, work, companionship, and study.
Historical Context
The history of animal husbandry can be traced back to the Neolithic Revolution when humans tamed animals. This activity predates agricultural production and played an important role in early human communities. Cattle, sheep, goats, and pigs were among the livestock animals used for agriculture during ancient civilizations.
Significant advances in animal husbandry were made during historical periods such as the Columbian Exchange and the British Agricultural Revolution. These events resulted in the importation of Old World livestock to the New World, as well as the fast development of cattle breeds through selective breeding and agricultural advancements.
Scope of Animal Husbandry:
Animal husbandry is divided into multiple categories or branches, each focused on a distinct aspect of growing and managing animals for specific uses.
Livestock production involves raising domesticated animals for various purposes, such as food, fiber, work, and other items.
Typical livestock species consist of:
Cattle: Mainly raised for their meat and milk, and in some areas, also for draught power.
Sheep: Sheep are prized for their wool, meat (mutton and lamb), and occasionally their milk.
Goats: Used for grazing, milk production, meat (chevon or goat meat), fiber (mohair, cashmere), and land management.
Pigs: Raised for their flesh, these animals have high rates of reproduction and effective feed conversion.
Poultry: Raised for their eggs and meat, this category includes chickens, ducks, turkeys, and geese.
Various regions use buffaloes, camels, horses, and donkeys for agricultural work, transportation, and milk production.
Aquaculture involves farming aquatic organisms through interventions like stocking, feeding, protection from predators, and other management practices.It includes fish, mollusks (like oysters and scallops), crustaceans (such as prawns), and aquatic plants cultivated in both freshwater and marine environments. Farming practices can range from extensive (using large water bodies like bays, lakes, or ponds) to intensive (utilizing cages, artificial reefs, racks, or strings to confine the farmed organisms).
The growing and management of honey bees to produce honey, beeswax, royal jelly, bee pollen, and pollination services is known as apiculture or beekeeping. Beekeepers take care of colonies, extract honey, maintain beehives, and use bee activity to help pollinate crops.
Sericulture is the cultivation of silkworms for silk production. Silk farmers rear silkworms on mulberry leaves, promote cocoon formation, and harvest silk threads for the textile industry. Sericulture includes breeding silkworms, managing their life cycle, and processing silk fibers.
In animal husbandry, genetics and breeding are very important. These fields concentrate on using genetic engineering and selective breeding to improve desired features in animals.
Inbreeding
Inbreeding involves the mating of closely related individuals within the same breed or family. Mating siblings within the same breed of cattle is an example of inbreeding aimed at concentrating specific genetic traits within the breed. It can increase the risk of genetic abnormalities caused by the expression of recessive genes. Inbreeding avoidance is crucial for maintaining genetic health and diversity in natural populations.
Outbreeding
Breeding unrelated individuals to introduce new genetic material and lower the risk of genetic defects, while also increasing hybrid vigor or heterosis. In animal husbandry, controlled outbreeding is frequently employed as a breeding approach to introduce genetic variation.
Crossbreeding
Breeding individuals from different breeds or species to combine beneficial traits from both parents, such as disease resistance or improved productivity. Mules are the result of crossing a male donkey (jack) with a female horse (mare). They are considered hybrids, exhibiting traits from both parent species.
Livestock nutrition plays a critical role in animal husbandry.
Ruminants like cattle and sheep can digest grass and forage, while non-ruminants like pigs and poultry require formulated diets rich in protein and energy sources.
Modern animal husbandry practices vary based on factors such as land availability, economic considerations, and technological advancements. This includes:
