Effect of Immediately-After-Birth Weaning on the Development of Goat Kids Born to Small Ruminant Lentivirus-Positive Dams

摘要

Caprine arthritis-encephalitis (CAE) is one of the most important and devastating viral diseases of small ruminants in developed countries. The disease spreads easily from one goat to another, and neither curative therapy nor preventive vaccinations exist to break the chain of infections. Hence, the only way to suppress the epidemic in a herd is to identify and cull infected goats. However, it is both costly and cruel as most of them remain apparently healthy for many months or even years, yet they constantly shed the virus. Therefore, many farmers decide to wean kids away from their infected mothers as soon as they are born and keep them in separation, feeding them on bovine or artificial colostrum and milk. Even though this approach is quite effective, it may be recommended only if it has no negative impact on kids’ development. Therefore, we conducted the study which compared the development of kids weaned immediately after birth and kids kept with mothers. We showed that early weaning did not seem to have any detrimental effect on kids’ health. On this basis, we conclude that this procedure may be an advisable alternative for those farmers who cannot afford to implement radical eradication program in their herds.
