Local breeds are the most common in Tanzania, especially under the extensive
system. The breeds have a high potential to withstand harsh conditions (hot and
dry weather). They are also disease-tolerant and can survive with minimal care.
Common local breeds include Tanzania Shorthorn Zebu (TZS), Boran and Ankole
(refer to Figures 10.3 (a), (b) and (c)). While local breeds can withstand harsh

conditions, they have a low growth rate and beef yield as compared to improved
breeds. However, Boran breed performs well and is sometimes comparable to
some improved or exotic breeds.

Exotic breeds are cattle breeds that were introduced to Tanzania from other
countries. Examples are Brahman, Charolais, Hereford and Simmental (refer to
Figures 10.4 (a) to (d)). These breeds have a high growth rate and high beef
yield. They are commonly managed under intensive and semi-intensive systems,
to ensure they are closely managed, monitored and receive better nutrition.
However, managing exotic breeds requires more resources and husbandry skills.
They perform well even in places with very hot weather or poor pastures.
