Abstract | During the study, the proportionate prevalence of joint ill was 2.47% in studied population. The incidence of joint ill was higher in female (57.14%) and calves having 75% Holstein Friesian (HF) blood (71.43%) in compare with male (42.86%) and calves having 62.5% HF blood (28.57%) respectively. During May to July the calves were more (71.43%) prone to joint ill in compare with that of February to April (28.57%). Navel ill was the most important (85.72%) predisposing factor for the joint ill infection. During study, a combined treatment with SP Streptomycin and Penicillin (SP) followed by Kanamycin, Colistin Sulfate, Neomycin and Dexamethasone (KCND) was found significantly (P<0.05) more (75%) efficient than treatment with SP only (0%). The isolated organisms from joint fluid were Escherichia coli and Staphylococcus sp. E. coli isolates were resistant to Ampicillin, Nalidixic acid, Chloramphenicol and Colistin sulphate whereas Staphylococcus sp isolates were resistant to Streptomycin, Nalidixic acid, Chloramphenicol and Colistin Sulfate. Both types of organism were sensitive to Tetracycline and Doxycycline. The mortality of joint ill infected calves was found 57.14%. So, prevention of joint ill through avoiding the predisposing factors and treatment of the affected animals with specific antibiotics after Cultural Sensitivity (CS) test can be recommended.
