Abstract
Studies on bovine mastitis were carried out in 13 small-holder dairy farms while bulk milk from 12 of these farms were tested for milk quality. Although hygienic practices were comparatively poor, the level of subclinical mastitis as low with 19.6'/, of animals and 8.0% of quilter’s infected. No clinical cases of mastitis was observed. The predominant bacterial species was Staphylococcus aureus and was isolated from 4.3.3% of samples and 83% of herds. Antibiotic sensitivity tests, an S. aureus isolates showed that 21%, 26.3% and 36.41, were resistant to penicillin, streptomycin and ampicillin, respectively. There was no resistant to chloramphenicol and tetracycline. The quarter infection rate among cows in the early and late lactation stages show a tendency to increase. The effect of lactation number on subclinical mastitis showed a highly significant increase in infection rate from the fifth lactation onwards. Quality tests on hulk milk showed that the average fat content was 4. 95'/, and total solids averaged 14.13%. The average total bacterial count was 55,316 per ml milk. The resazurin reduction test showed that all the milk samples tested were of acceptable quality . Storage of milk at 7°c for. '18 hour did not produce any deterio- rating effects.
