Abstract:

The purpose of this investigation was to establish the mastitis status in the dairy herd of 110 cows (genetically heterogeneous Bos Taurus breeds). All the cows were examined by physical inspection of the udder and California Mastitis Test (CMT) carried out on milk from the quarters of the 89 cows in milk. A total of 37 milk samples were collected from affected quarters of 36 cows, which had visibly abnormal secretion or tested positive on CMT, and taken for bacteriological culture and sensitivity tests. The outcome was a prevalence of 40.4 % based on the cows in milk and 18.4% based on their quarters. From the 37 samples that were cultured, 36 had abundant bacterial growth. Of the bacteria isolated, 45 % were Corynebacteria, 30.0 % Staphylococci, 22.5% Streptococci and 2.65% Pseudomonas. Of the twelve antibacterial compounds used in the sensitivity tests, the bacteria were most sensitive to ampi-clox and cefaclor at 98% and lest sensitive to sulphamethoxazole and cotrimoxazole both at 2%. Pseudomonas was only sensitive to gentamycin, norfloxacin and tetracycline. From this investigation the prevalence of mastitis in the herd is fairly high and there is need for a comprehensive monitoring and control program for udder health in this herd
