The greatest problem associated with cattle rearing in West Africa is the presence of tse-tse fly. Tse-tse flies are bloodsucking insects that transmit a parasite causing African animal trypanosomiasis or nagana disease in cattle. This disease reduces the productivity and growth of the animals, resulting in lower milk and meat yields. The presence of tse-tse flies also restricts the areas where cattle can graze, making it difficult for farmers to find suitable grazing land for their herds. This ultimately leads to reduced profits for farmers and hinders the growth of the cattle industry in West Africa.
