This thesis describes a study of the epidemiology of theileriosis on smallholder dairy farms in Murang'a District situated in central highlands of Kenya. The main objectives were: 1) to characterise different areas within the district as to their risks for tick-borne diseases (TBDs), in particula...

Eimeriosis is caused by a protozoan infection affecting most domestic animal species. Outbreaks in cattle are associated with various environmental factors in temperate climates but limited work has been done in tropical settings. The objective of this work was to determine the prevalence and env...

The purpose of the study was to characterize the differences in epidemiology (risks of infection. morbidity. mortality) and potential control of East Coast fever (ECF) between the selected strata. Evidence of Theileria parva infection was assessed by increased antibody levels as measured in an in...

The Murang'a District is situated in central Kenya and is a highland area with a high potential for dairy production. This study was carried out to evaluate the performance of smallholder dairy farms by analysing available data and by simulation modelling. Eighteen case farms were selected non-ra...

Two experiments designated A and B were conducted to evaluate the effect of supplementing napier grass with lucerne on dry matter intake (DMI) and weight gain (ADG) of Friesian and Sahiwal heifers. In experiment A which lasted 92 days, 24 heifers from each of Sahiwal and Friesian breeds were bloc...

A study was conducted to investigate the effect of feeding napier grass (Pennisetum purpureum) with or without legume supplementation on nutrient intake and live-weight gains (LWG) in dairy heifers. Thirty-two, 1-year-old Friesian and Sahiwal heifers were used. Eight heifers, four from each breed...

The aim of this study was to evaluate accuracy of farmer's paternity identification which determines success of future breed selection and hence genetic gain. Paternity of 269 Orma/zebu and Sahiwal/zebu calves was evaluated using genetic markers and the likelihood based method. Results indicate t...

A prospective observational study was conducted among smallholder dairy farmers in Murang'a District, Kenya, to estimate the incidence of Theileria parva infections, as well as calf morbidity and mortality caused by the infection. The study was conducted between March 1995 and August 1996, in fiv...
