Summary

The effects of different deworming methods of grazing and lactating goats on fecal egg count (fec) and milk yield were examined. Fec was determined by a modified McMaster method with a sensitivity of 40 eggs per gram feces. At day 66 of the grazing period, the animals were allocated to two groups depending on the milk yield (low = MN, high = MH). Half of each group was dewormed. In the first year of the trial
animals with low as well as high fec were dewormed. The averages of fec in the groups (C-0 = no deworming, C-M = deworming) were not different at the time of
deworming. In the second year of the trial only animals with high fec were dewormed. The averages of the EPG in the groups (C-0 = no deworming, C-H = deworming) were different at the time of deworming. Examination weeks were combined to three periods (week1-9 (before deworming), week10-15 (after deworming), week 16-22 (fec after deworming)). Deworming had a significant influence in fec in week10-15, but not
in week 16-22. Deworming resulted in lower fec as a short term effect and elevated fec as a long term effect in both deworming regimes. One possible reason therefor could be a lack of immunity due to deworming.
