| Popis: | A clinical trial was performed to compare the effects of flumethrin and ivermectin treatments of grazing heifers at one farm in central Japan. 64 heifers were randomly allocated into two groups. Flumethrin (1 mg/kg pour on) was applied approximately once every 3 weeks to heifers in one group and heifers in the second group were injected approximately once every month with ivermectin (200 microg/kg; id). Between groups, no significant differences were detected in the proportions of animals that showed parasitemia of Theileria sergenti and conception risks. Significantly lower average log-transformed nematode-egg counts and higher average daily weight gain were observed in the ivermectin-treated group. Animals with higher body weight at the start of grazing and lower log-transformed total nematode-egg and coccidia-oocyst counts had higher odds of conceiving. Animals with ivermectin treatment, lower body weight at the start of grazing and lower log-transformed coccidia-oocyst count had higher daily weight gain. Ivermectin may be more useful in this farm because of the higher productivity for cattle and lower cost for its usage. |
