摘要:

Goat kids from a herd endemically infected with caprine arthritis encephalitis (CAE) virus were raised according to 3 methods. One group of ten goat kids was removed from infected does at birth before suckling or licking by the doe could occur (snatch birth techique). Kids were fed on goat colostrum, which had been heated to 57°C for ten minutes and then held in a thermos flask for one hour. Subsequently the kids were fed reconstituted spray dried cows' milk powder. They were raised apart from infected goats with separation maintained by a wire fence. Contact occurred across-the-fence. Passively acquired serum antibody to CAE virus was detected in some kids at two to three months of age. Nine of the ten goats were negative for serum antibody to CAE virus when tested at 5–6, 9 and 12 months of age. One goat was positive at three and nine months of age but was negative when tested at 12 months of age.

摘要:

A field strain ofCooperia oncophoraresistant to oxfendazole was isolated from a commercial cattle rearing property in Waikato, New Zealand. Resistance to oxfendazole was assessed by means of a faecal egg count depression test and anin vitroegg hatch test.

摘要:

A controlled slaughter trial was undertaken to compare the efficacies of oxfendazole (5 mg/kg), morantel citrate (10 mg/kg), levamisole (8 mg/kg) and ivermectin (0.2 mg/kg) against experimentally induced infections of adultHaemonchus contortus, Ostertagiaspp.,Trichostrongylus colubriformisandCooperiacurticeiin sheep and goats. Ivermectin and oxfendazole achieved similar levels of efficacy in both hosts against all four worm genera as did levamisole and mortantel againstH. contortusandC. curticei. AgainstOstertagiaspp. andT. colubriformis, however, the latter two drugs were less effective in goats than sheep. Neither the numbers ofOstertagiaspp. removed from goats by levamisole (81% reduction) nor the numbers ofT. colubriformisremoved from goats by morantel (56% reduction) were statistically significant (P>0.05).
