In the years 1987-1988, twenty Mpwapwa in-calf heifers and six bulls were sold to individual farmers of Berege willage in Mpwapwa district, Dodoma region. After calving, most cows produced on average about four liters of milk per day of lactation, beside the milk suckled by the calf. This product...

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...

The history, origin and characteristics of the South African Boer breed of goats are reviewed. The development was carried out by a handful of farmers in the eastern Cape, particularly in the district of Somerset East. The prototype for the breed was selected from several existing breeds of goats...

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...
