Data collected in the Mt. Kulal area of the Marsabit district by the Integrated Project in Arid Lands (IPAL) are being analyzed for use in simulation studies. Weight, lactation, reproduction, health and forage quality and availability data were collected from flocks of Galla goats and Somali shee...

Seasonal breeding is potentially a powerful intervention affecting productivily, particularly so in semi-arid environments where seasonal differences are great; however, variability is also great, increasing the risk for such interventions. Simulation was used to examine the effects of 5 breeding...

Red Maasai [Masai] and Dorper sheep were evaluated for their resistance to gastrointestinal nematode parasites (predominantly Haemonchus contortus), productivity and efficiency in experiments undertaken at the Kenyan coast (humid environment) and the Kenya highlands (semiarid environment). It was...

Various fertility parameters are under investigation in the Small East African goat at Isiolo, northern Kenya. A programme of aseasonal breeding is used and parameters are examined in relation to the quantity and quality of forage available. Breeding groups consisting of 18 females each are used:...
