Past attempts to alleviate the problems of poor farmers engaged in mixed-crop-livestock production have generally focussed on the design and diffusion of new technologies targeted on specific components of the agroecosystem. Unfortunately, such piece-meal efforts have had little impact in the dev...

Cereal-legume intercrops are quite common in sub-Saharan Africa. However, most of the research in this area has concentrated on grain legumes or pasture grass-legume mixtures. More recently, attention has been called to the integration of forage legumes with livestock production. While it is know...

A study was initiated on selected populations of Trifolium tembense collected from the Ethiopian highlands. The species was an annual autogamous clover which is native to the African highlands. In the study, both plant and soil variables were utilized for investigating possible LbP (local breedin...

Presents results of a study conducted to assess the extent to which incubation time, temperature or failure to separate plasma soon after collection influence the plasma progesterone concentration in Ethiopian indigenous sheep.

Data augmentation is a powerful technique for estimating models with latent or missing data, but applications in agricultural economics have thus far been few. This paper showcases the technique in an application to data on milk market participation in the Ethiopian highlands. There, a key impedi...

The trace element status of crossbred Friesian X Zebu (Boran) and local Zebu cattle in the Selale highlands of Ethiopia was evaluated during the rainy and dry seasons of 1989 and 1990 interms of the trace element content of soils, feeds, blood plasma and faeces on 25 randomly selected farms. Live...

The genus Leucaena is one of the most important sources of multipurpose trees and shrubs for use in farming systems in the African tropics and subtropics. In previous studies, Kashsay and Tothill (1995) identified the superior performance of Leucaena pallida and L. diversifolia as highly producti...

A study conducted to evaluate transmission rates of fascioliasis, using parasite-free ewes and their lambs as tracer animals, under dif. watering practice and to assess the value of enzyme-linked immunosorbent assay (ELISA) in studying the epidemiology of the disease.

The effects of breed (Menz and Horro), season (wet and dry), and the breed by season interaction on production and response to naturally acquired gastro-intestinal (GI) nematode parasite infections (predominantly Longistrongylus elongata and Trichostrongylus spp. and a small proportion of Haemonc...
