摘要：Urban livestock production has recorded significant growth in East Africa since the 1970’s. However, proximity to cattle creates potential to public health hazards due to poor hygiene caused by the presence of dung, and flies and parasites that transmit zoonotic diseases. These environmental problems from urban cattle farming threaten both human life and natural ecosystems. The objective of the current study was to assess the patterns of cattle keeping in Nakuru Municipality in Kenya, and identify cattle waste disposal mechanisms in relation to environmental pollution. Through a cross-sectional survey, primary data was collected using sets of structured and semi-structured questionnaires and focused group discussions. To select respondents to be interviewed, stratified sampling was used followed by simple random sampling within the strata. Fishers Exact Formula was then applied to get the 186 cattle keepers that were interviewed. Subsequently, descriptive statistics was used to describe the results, and Chi-square and paired t- tests performed to determine the existence of differences between observations. Results indicate that almost all cattle (80% of the respondents) were found either on owners’ and landlords’ plots. The number of cattle kept on “own land” differed (P<0.005) from that reared on “tenant/ rental” land (t 183 =7.95, P=0.000). Majority of the cattle were grazed on roadsides/ streets, some under zero-grazing and the rest (10.3%) under semi zero-grazing. Differences existed between various production systems, i.e., zero-grazing vs semi zero-grazing (t 77 =2.280, P=0.012) and roadside/ street grazing vs semi zero-grazing (t 165 =3.50, P=0.001). Much (52.2%) of the cattle waste was used as manure for crops, and the rest (10.2%) dumped on the streets, and dustbins, pits and compounds (10.2%).Use of waste as manure on crops differed from giving it away to neighbours, 26.9%, (t 145 =3.137, P=0.001).Generally, land was a limiting factor that made the cattle keepers opt for free-range grazing system, which exposed the Municipality to cattle waste. Use of manure on crops as the major method of waste disposal was inadequate as a means of disposal, resulting in exposure of the Municipality to a serious problem of cattle waste. The findings of this study provide information that the Municipal authorities, policy makers and cattle keepers would need in terms of managing the menace of cattle waste in the Municipality.
