    Types of cattle/goat breeds
    The term ‘breed’ means a group of animals with similar characteristics.
    There are two main types of cattle breeds namely.
    • Local (indigenous) breeds
    • Foreign (exotic) breeds

    a) Local (indigenous) cattle breeds

    These are cattle breeds that are found locally in Rwanda. They are
    native cattle that can withstand hostile climatic conditions and are also
    resistant to tropical diseases. They have long legs and they can walk
    over long distances looking for food and pasture. Their productivity is
    generally low and they are small in size. Examples of indigenous cattle
    breeds include:

    and have well developed horns

    n

    horns and big humps. They produce good quality beef.

    g

    d

    Beef cattle breeds
    These are purposely kept for meat production.
    They include:

    Aberdeen angus, Hereford, Charolais, Shorthorns and Galloway.
