The aims of this study were to find the time when they first contracted internal parasite infections, as well as to determine the severity of the infections and also its relation to production indicators (body mass and packed cell volume) of the kids as they grew older. The results indicate that they contracted coccidial and roundworm infections at approximately one month of age or immediately thereafter. The most prevalent internal parasite was coccidia, which occurred throughout the study period, followed by roundworms, and the least was the tapeworm, Moniezia expansa. Generally, the infection levels of all internal parasites were lower than the critical mean log (faecal oocyst/egg count + 1) of 3.3 inferred to cause reduced production in small stock. The correlation coefficients were all positive; 0.4-0.9 for individual internal parasites and production indicators, indicating that these internal parasites did not have any adverse effects on production. It was concluded that there was no need to treat kids of this age group for internal parasites.© ARC-Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © University of Pretoria.
