Effects of PPR vaccine on goat haematology in tangail district of Bangladesh

The present study was conducted during the period may 26,2007 to july 2,2007 to observe the blood parameters of 18 she goats of the same age after vaccination with ppr vaccine after challenge with field virus. the within-subjects test indicated a significant (p<0.01) time effect on tec. the interaction effect of vaccine on tec over time was significant (p<0.05). the between subject effect of vaccine on tlc was significant (p<0.01). that is,the mean values of tlc at different doses of vaccine varied significantly. double dose of vaccine reduced tlc to a significant (p<0.05) extent with respect to single dose and single dose boosting after 7 days of vaccination. hb at the 1st,2nd,3rd and 4th observations were computed and the reduction of hb estimation at each of 7 days duration was significant (p<0.05). the within-subjects test showed a significant (p<0.01) time effect on hb of goats. hb concentration declined cubicly over time. the interaction effect of vaccine on hb over time was significant (p<0.01). the increment of esr was recorded as significant (p<0.05) at 3rd and 4th observations. the within-subjects effects on esr reveal that time had a significant (p<0.01) effect on esr. the values of esr changed in a quadratic pattern over time. the test of within-subjects effects showed a significant (p<0.01) time effect on the values of pcv of goats. the values of pcv changed in a linear form over time which reveals that the ppr vaccine affected the hematological parameters of the goats at different patterns over time.
