Two recombinant vaccines against Theileria parva, based on a near full-length version of the sporozoite surface antigen p67 (p67635), or an 80 amino acid C-terminal section (p67C), were evaluated by exposure of immunized cattle to natural tick challenge in two sites at the Kenya Coast and one i...

revious experiments have shown that mixed or conjoint grazing, when two or more animal species are grazed together, can lead to improved performance of one or more of the species and a higher total output per unit area. Sequential grazing systems, when different animal species graze an area in su...

An experiment was conducted in 1996 and 1997 in semi-arid Niger, to determine the influence of supplementation (no supplement, millet bran + simple superphosphate, or millet bran + simple superphosphate + blood meal) for cattle and mulching (0 or 3 t ha-1 of Aristida sieberiana straw) on soil fer...

A clinical trial, comparing East Coast fever (ECF) control strategies in 5 different groups of traditionally managed Sanga cattle (44-49 animals per herd), was conducted in Zambia over 2.5 years between 1992 and 1995. Two groups were kept under intensive tick control by weekly cypermethrin (Barri...

Bovine babesiosis has been identified clinically in many areas of Morocco. A seroepidemiological survey of B. bigemina infection was conducted in the 5 main dairy cattle areas in order to estimate the prevalence of the infection. A total of 1819 bovine sera was tested using ELISA to identify ani...

Five tropically adapted buck breeds extensively managed in Ethiopia were studied to determine possible effects of breed and age on body size and testicular traits. In all, 177 bucks were selected following stratified random sampling, and evaluated in three age groups: <14 months (young), 14-19.5 ...

The effects of holding temperature, pH and medium on the infectivity of Theileria parva sporozoites were investigated using an in vitro infectivity assay. The sporozoite infectivity lasted for 72 h at a holding temperature of 4 C but for only 24 h at 24 degrees C. Sporozoite infectivity was fo...
