- Abstract
The control of helminth infections has an essential role in the productivity of dairy cattle. Sustainability, cost/benefit and feasibility of the chosen control measures, must be taking into account for each production system. This study aimed to establish criteria for anthelmintic treatment of dairy cattle, in different categories, based on eggs per gram of feces (EPG) counting. For this purpose, it were analyzed fecal samples from 100 dairy cattle, in different age groups, from small farms of the Central region of Rio Grande do Sul state, Brazil. Based on these results, the selective treatments, based on EPG, are indicated to female calves (until three months old) and lactating cows, and the strategic control to male and female calves, from four to 24 months old.
