摘要

Similar to other domestic livestock, llama and alpaca crias are born hypogammaglobulinaemic (Garmendia et al, 1987); (Garmendia and McGuire, 1987); (Drew and Fowler, 1995); (Weaver et al, 2000a). The ingestion of colostrum from the dam provides essential immunoglobulins to bolster the immune response of the neonate. Studies performed in both the United States and in Peru have demonstrated that crias with failure of passive transfer have higher mortality rates than those with adequate passive transfer status (Garmendia et al. 1987): (Johnston et al, 1997). Recent work has also been done investigating testing modalities for establishing passive transfer status in these species (Weaver et al, 2000b). Despite the increase in attention to passive transfer in camelid species, there are currently no studies that document colostral immunoglobulin G levels in these species. Studies that evaluate factors influencing passive transfer status are also lacking in new world camelidae. The current study examinesrelationship between maternal colostral IgG concentration and the subsequent serum IgG concentrations attained in the neonate.
