SUB TOPIC 1: Meaning and Uses of Pasture and Forage Crops

A Pasture is an area of land on which grasses and legumes (forages) grow for animals to graze. Forage crops are plants cultivated for their vegetative portions in a pasture and are used either in fresh or preserved for feeding livestock such as cattle, sheep and goat. They may be harvested and fed to the animals in their shed (soiling/zero grazing) or animals are allowed to graze directly on the field.

USES OF FORAGE / PASTURE CROPS

1. Forages account for a major source of food for ruminant animals
2. They serve as cover crops to conserve soil moisture and prevent soil erosion.
3. They could be used as green manure e.g forage legumes
4. They can be used for roofing farm stead e.g grasses

SUB TOPIC 2: Types of Pasture

There are two main types of pasture: the natural and artificial pastures

1. The Natural Pasture: The Natural Pasture otherwise known as range land is an extensive grassland containing forage grasses and legumes, straws and other wildlife. An example of Natural Pasture is Savanna areas. They are not planted by man.

CHARACTERISTICS OF NATURAL PASTURE

1. It has a good ability to regenerate
2. The soil types have low fertility
3. Some inedible grasses and legumes by the animals are found on such land.
4. The grasses and legumes are usually of poor quality
5. It may contain some stubborn grasses which may be difficult to eradicate.
6. The forages are seasonal being scarce during dry season
7. It harbors wild animals.
   

1. The Artificial Pasture: This is an established or sown pasture. The grasses and legumes are deliberately planted for livestock to feed on. This is planted and managed by man.

CHARACTERISTICS OF ARTIFICIAL PASTURE

1. Grasses and legumes are selectively grown in a proper proportion, in the ratio of 60:30:10 (grass, legumes and herbs)
2. It is weed free
3. They contain high quality grasses and legumes.
