Animals suffer from the ravages of bot flies (Oestridae) and gad flies (Tabanidae); while the tsetse disease is due to the tsetse fly (Glossina morsitans), carrying the protozoa that cause the disease from one horse to another.
Even better pasture is found in the low veld, but there stock suffers in summer from many endemic diseases, and in the more northerly regions is subject to the attack of the tsetse fly.
Tsetse-flies are of great economic and pathological importance as the disseminators of tsetse-fly disease (nagana) and sleeping sickness.
The tsetse fly (Glossing morsitans) infests several districts; the sand-flea has been imported from the west coast.
Domestic animals include the horse and donkey in the plateaus, but baggage animals are rare in the coast-lands, where the tsetse fly is found.
