Factors influenced by climate change and that could affect livestock diseases include the molecular biology of the pathogen itself; vectors (if any); farming practice and land use; zoological and environmental factors; and the establishment of new microenvironments and microclimates. East coast fever had the highest (68%) morbidity rate of all the five diseases and appeared to affect the adults - (26%) than the weaners - (21%) and calves - (21%) classes respectively. However, mortality was slightly more in the younger age classes. Foot and mouth disease had the second highest reported morbidity at 52% and affected slight...

The effect of age, breed and month of the year on semen volume, spermatozoa concentration and motility were studied. The second ejaculate volumes, concentrations and motility were significantly higher (p The Kenya Veterinarian Vol. 18 (1) 1994: pp. 8-11
