Coefficient of variation and standard deviations across herds were used to test heterogeneity of variance. Average herd standard deviation and coefficient of variation after correcting for the fixed affects were 672.2kg and 26.7% respectively, while scaled standard deviations between herds were 180.1kg and 3.4%.The scaling of observation s within individual herds by sample standard deviation minimized heterogeneity of variance of milk yield thereby increasing accuracy of selection. It was concluded that significant heterogeneity of variance in milk yield existed among herds and should be accounted for in sire and cow evaluation.

Direct and indirect areas that contribute to financial losses were identified for the period of observation (95 days) the greatest direct financial impact due to milk losses (42.0%) followed by purchase of additional feeds (13.6%) and culling of milk cows that developed chronic mastitis (12.5%). the other direct costs were extra labor inputs (8.9%), veterinary fees (3.3%), transport (3.0%) deaths(3.0%) drugs(2.9%) abortions (1.4%) and chemicals (0.5). the indirect costs associated with the effects of the quarantine period on other farm enterprises. During quarantine period on other farm enterprises. During the quarantine period there were no sales of pigs and hay and the retained pigs in addition to not fetching premium prices required additional feeds. The overall short-term farm level direct and indirect costs associated with outbreak amounted to Ksh 1,201,950 equivalent to US $ 16,026 (1 US $= 75Ksh.). This colossal economic loss within such a short period of time indicates that the control of FMD is of paramount importance in the diary farming sector in Kenya.

The lesions observed were matting together of hair into small tufts (greasy crusts) and discrete circumscribed lesions covered with creamy greasy crusts. The matting of hair into small tufts was found all over the body, while the discrete circumscribed lesions were mostly found in the distal extremities, dewlap, brisket, flank and dorsal midline. The circumscribed crusty lesions were similar to those of Trichophyton verrucosum infections that occur in similar production systems in Kenya, in that they were thick, horny and raised above the skin surface. However, unlike Trichophyton verrucosum infections, the crusts were held in place by penetrating hairs. Treatment of the severely affected cow with a single intramuscular injection of long acting tetracycline (20 mg/kg) resulted in regression of the lesions within 4 weeks, while in the mildly affected animals; the lesions receded on their own.
