Abstract |
Comparison of body weight changes of does infected with Haemonchus contortus(treatment groups 2 & 3) and uninfected does(control group) was made using weekly body weight measurements over 35 weeks. The animals in treatment group 2 weighted significantly(p<0.05) less than animals in the control group from the 5th week to the end of the experiment. Does in treatment group 3 had significantly(p<0.05) lighter body weight than control does from the 13th week to the end of the study. The animals in control group gained an average of 0.75 kg. On the other hand, animals in infected groups 2 and 3 lost an average of 3.90 kg and 4.13 kg body weight, respectively. The animals in groups 2 and 3 also had significantly(p<0.05) lower preslaughter and hot carcass weights than the controls. |
