Introduction To Range And Pastures

Aperçu

Drive north out of Kaduna towards Sokoto in August and the landscape is a rolling carpet of green, tall grass swaying shoulder-high beside the road, cattle spread wide across it with a Fulani herdsman walking behind. Make the same drive in February and the same land is brown, cropped almost to the soil, dust rising with every hoof. Nothing about the land changed except the season, yet it decides whether a herd eats well or eats poorly, and whether it stays put or treks a hundred kilometres south in search of grazing.

In this lesson you will learn what separates a range from a pasture, and a natural pasture from an artificial one; meet the grasses and legumes a Nigerian farmer relies on for grazing; and understand why this single, unimproved resource still feeds more of Nigeria's cattle, sheep and goats than any manufactured feed ever could.

Objectifs

  1. Define range and pasture
  2. Distinguish between natural and artificial pastures
  3. State the importance of range and pasture to livestock production
  4. Give examples of common pasture grasses and legumes in Nigeria
  5. Explain the factors affecting pasture growth

Note de cours

Ask a Fulani herdsman what he feeds his cattle and he will point at the land itself. Across most of Nigeria, ruminant livestock, cattle, sheep and goats, are raised almost entirely on grazing, not purchased feed. For the extensive system that still carries the bulk of Nigeria's livestock, range and pasture are the whole feed budget.
