Abstract
Four hundred and nine (409) milk producing cows , from 32 resident farms in Kassala city, Elgash area, Fato and New Halfa sugar farm, were subjected to Comparative Cervical Tuberculin Test CCTT to determine the effect of ventilation, hygiene, tick free, square available for animal head (AH), exposure to sun rays and nutritional balance factors on the prevalence of bovine tuberculosis. Every factor had three criteria that required obtaining the highest score (3), according to the availability of one or two criteria the factor gave score (1) and score (2) respectively and scoring zero in case of absence of the three criteria. The results of this study showed that the differences between the results of CCTT in score1and score 2 for ventilation and exposure to sun rays were all significant (P = 0•000) and (P = 0•001) respectively , whereas the differences between results of CCTT in score 0,1 and 2 for hygiene , tick free , square available for animal head and nutritional balance were all insignificant .(P = 0.402 , P = 0.371 , P = 0.276 , P = 0.208 ) respectively .
