ABSTRACT
Lameness is a cause of worry to dairy producers for being indicative of welfare problem with resultant economic losses from reduced milk yield, veterinary cost or premature culling. Risks for lameness are both animal and herd level factors, but the magnitude varies with housing conditions of the cows. This study compared farmer estimated and observed prevalence, types of lameness, risk factors and economic losses from lameness of cows in farms practicing zero- and pasture grazing. The study was conducted in Nakuru County, Kenya where zero- and pasture-grazed cows were obtained in an observational study design. In a random sample of 172 smallholder farms, 485 cows were examined for lameness, individual records and performance histories. Data were subjected to Chi square test, means comparisons and spearman rank correlation. Results showed that lameness prevalence was not different between zero-grazed (23.0%) and pasture grazed (20.2%) cows. The prevalence of lameness observed (22.1%) and that estimated by farmers (22.7%) closely matched with a strong positive and significant correlation (r=0.959; p
