Abstract
CAE is caused by a lentivirus. The animals are mainly infected when taking contaminated colostrums and/or milk. This study proposed a CAE control strategy without sacrificing contaminated mothers. Thirty-nine female kids, born to CAE seropositive mothers were isolated from their mothers at birth and fed heat-treated colostrums and pasteurized milk from seronegative goats up to two months of age. All kids were submitted to three-monthly serological tests from birth to 12 months; seropositives were segregated from the herd. The control group consisted of 12 kids born to seropositive mothers that remained with their mothers. Diagnosis was the same, but seropositve animals were not segregated. At the end of 12 months, 34 (87%) animals from the experimental group remained seronegative with 76% to 98% confidence limits; in control group animals, the accumulated negativity rate was 17%, with 0% and 38% confidence limits. These results show that the proposed plan is viable to assure disease control in contaminated herds and that without it contamination can pass to animals born to infected goats.
