As livestock disease control programs in Africa begin to rely more upon para-professionals and livestock producers as deliverers of animal health care services, understanding the role different household members play in providing animal health care becomes increasingly important. This paper prese...

Evaporation of water from 'micro-lysimeters' collected from four types of field tillage treatments, namely, ploughed to a depth of 30cm (P), ploughed and then harrowed (P + H), ploughed, harrowed and rolled (P + H + R) and untilled (UNT) plots, was studied in a controlled laboratory environment a...

The available world collection consisting of 257 accessions of the tropical pasture legume Centrosema brasilianum (L.) Benth. was assessed between 1993 and 1995 in northern Nigeria to complement existing knowledge on the genetic diversity of this species and to identify accessions with high agron...

We obtained blood samples of 57 Indian ducks (Anas platyrhynchos) belonging to three indigenous duck populations of geographically distinct locations of the country and genotyped them using chicken microsatellite markers. Twenty three of the 30 loci were amplified and 17 loci yielded high success...

The purpose of this study was to assess the genetic characteristics of six breeds of Chinese local sheep using 19 microsatellite loci and to effectively validate statistical methods for individual assignment based on informative microsatellites. All the six breeds deviated from Hardy–Weinberg equ...

Haematological parameters were studied in 377 apparently healthy sheep comprising three indigenous breeds of Ethiopia. The effect of breed, age, gender and season on the haematological values was assessed. There was significant (P<0.01) breed difference for all erythrocytic series. Red blood cell...

Events occurring in the skin of sheep prior to development of Trypanosoma congolense-induced local skin reactions (chancres) were studied using electron microscopy. Three days after infection, few trypanosomes were present in the dermal collagen. However, these parasites were more abundant 5 days...

The inability of CERES-Maize v3.0 to simulate a fluctuating water table has been identified as a major constraint in using this particular model in South Africa and in Kenya. Information regarding fluctuating water tables under specific conditions, and their influence on maize production, has bee...

A study was conducted in Ngurunit and Kargi locations of Marsabit district in Kenya to determine the effect of mineral supplementation on milk yield and calf growth of settlement based camels. Two mineral supplements were formulated; one comprised of locally collected, ground bones mixed with loc...

Knowledge of genetic diversity within and among genotypes of any crop is fundamental for estimation of the potential genetic gain in a breeding programme and effective conservation of available genetic resources. Currently, different molecular marker techniques are being developed for measuring g...
