Postpartum ovarian activity was investigated in dairy cows in urban/peri urban dairy production systems in and around Addis Ababa using milk progesterone profiles. Nineteen crossbred (Friesian x Zebu) dairy cows which calved between March and June 1998 were used for the study. Milk samples were c...

The study was conducted to evaluate the reproduction efficiency of zebu and crossbred cows measured by the inter-estrus and inter-service intervals using data from Bako Agricultural Research Center. The overall mean inter-estrus and inter-service intervals were 44.3 t 0.85 and 49.1 t 1.24 days, r...

In a 2x2 factorial trial involving 80 does kept under traditional management, the milking potential of the indigenous Malawi goat was determined and the effects of supplementary feeding examined. Feeding was based on grazed indigenous pasture, largely Hyparrhenia spp only and with supplementation...

African animal trypanosomosis is a parasitic disease that afflicts livestock across much of sub-Saharan Africa. The disease, primarily transmitted by the tsetse fly (Glossina spp.), causes morbidity and mortality in several species of livestock. It is particularly important in southern Burkina Fa...
