Meaning Scope And Importance Of Animal Husbandry
Visão Geral
Walk through any Nigerian market and you will see the results of animal husbandry before you see the word itself: crates of eggs from a poultry farm in Ogun State, a side of beef from cattle trekked down from Sokoto, a bowl of snails from a backyard pen in Enugu. Animal husbandry is the branch of agricultural science that turns living animals into food, income and raw material, on purpose and by design, rather than by accident. It is the twin of crop production, and together the two make up the whole of agriculture.
In this lesson you will learn exactly what animal husbandry means, the six major enterprises that make up its scope in Nigeria, and why the subject matters far beyond the farm gate: to the food on a family's table, to the income of millions of Nigerian households, and to the wider economy. You will also learn how animal husbandry connects back to crop farming, so that the two branches support rather than compete with each other.
