Phosphorus is important for cowpea production in many tropical African soils with inherent low P fertility. Most farmers in Africa, however, do not have access to P fertilizer. Selection of cowpea lines that produce good yield under low soil P or those with high P-use efficiency can be a low inpu...

This paper reviews the current status of application of artificial insemination (AI) in poultry in Ethiopia. The technique was not practiced in the country before 2002. The application of AI in chicken in Ethiopia has been tested by comparing natural mating (NM), natural mating plus artificial in...

Seventy 1- to 4-year old female indigenous goats were matched and randomised into two groups to measure the effects of naturally acquired trypanosome infections on oestrus and conception. All goats were treated twice with diminazene aceturate (Berenil) at 7 mg/kg body weight at two-week intervals...

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...
