Abstract
Antibody ttre against Pasteurcila multocida was determined by indirect haemagelutination test in the purificd colustral immunoglobulins of ten crussbred cows. All cows had a varying amount (1:4-1:1024) of indirect haemagglutination an- libodies in their colostrum. The geomcan antibody titre from jusi after parturition to 72 hours (at 12 hour intervals) ranged [rom 3.24 to 181.00. Correlation between Lime intervals and geomean antibody titre against Pasteurella muthocida was t = -0.9107 (P<0.001). The regression equation indicated a decrease of 2.58 in geomeuan titre per hour increase in time,
