简介
The negative impacts of mastitis on milk production pose a challenge to the profitability and sustainability of small scale dairy enterprises, thereby affecting the social welfare of farmers. The prevalence and epidemiological profile of Caprine mastitis in Botswana remains undocumented. The objective of this study was to determine the prevalence of Caprine mastitis in mid lactating goats in the Oodi extension area of Kgatleng District, Botswana. A cross-sectional study was conducted in which a total of one hundred and sixty-three (163) lactating goats from 17 flocks were purposefully selected based on the use of goat milk and stage of lactation (45 to 60 days post-partum). All goats were subjected to clinical examination and Somatic Cell Count Test (SCC). Samples with SCC above the threshold of 0.5× 106 cells/ml were classified to be infected with sub-clinical mastitis. Each milk sample (0.5 ml) declared positive from Nucleo-counter SCC was further subjected to bacteriological tests to isolate for bacteria. The overall prevalence rate of mastitis was 17.8%(95% CI), with a significantly (P< 0.05) higher prevalence rate for sub-clinical (13.5%) than clinical mastitis (4.29%). Most (93%) of the cases of mastitis were due to Coagulase Negative Staphylococci (CNS). Positive cases were also isolated for Staphylococcus aureus (83%), Streptococcus species (62%), Escherichia coli (48%), Bacillus species (41%) and unidentified gram negative bacteria (51%). Caprine mastitis was significantly (P> 0.05) associated to risk factors; parity class, breed, housing floors, flock size and suckling litter number. Sub-clinical mastitis was four times more prevalent than the …
