Survey of parasites in dairy goats.

The survey was performed to study prevalence and intensity of parasitic infection in goats. Fecal samples were examined from 336 goats in southeastern Pennsylvania and northern Maryland. On the basis of fecal egg, oocyst, and larval counts, the following results were obtained. Eimerian oocysts were found in 100% of the fecal samples and the greatest fecal oocyst counts were found in goats under 6 months of age. Strongyle eggs and Strongyloides eggs were present in 76% and 20%, respectively, of the samples. Moniezia eggs were found in 9%, Trichuris eggs in 4%, and Nematodirus eggs in 1% of the samples. Twenty of 24 flocks examined for Muellerius capillaris were infected with this parasite. In these 20 flocks, 83% of the goats examined were infected with the parasite. Skrjabinema caprae infections were found.
