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...

Records on liveweight, growth and reproductive performance of Blended (BLD), Blended x Galla (BG) and Kamorai x indigenous (KI) goats for a period of over 10 years (1970-1980) in Malya, Tanzania were analysed. For BLD, BG and KI goat kids, birth weight and live weight averages were determined. Se...

After a preliminary common lambing, Horro ewes were mated either twice at 12-month intervals or three times at 8-month intervals over a period of two years. There were no significant differences between the two mating systems in their productivity at each lambing. However, ewes in the 8-monthly s...

Methods for biodiversity conservation are reported and applied to 49 African cattle breeds (26 taurine/sanga and 23 zebu/zenga (ZZ) breeds). It was estimated that about half of the breeds and half of today’s genetic diversity between breeds would be lost within 50 years. Based on a survey and a l...
