Abstract

The necessity to identify and utilize superior fibre producing goats has led to the demand for artificial breeding techniques to be developed within New Zealand. Particular emphasis has been placed on cervical insemination by Ambreed as it is seen as the most cost efficient methods, especially at a commercial level. Bucks have been selected on individual fleece data and stood on licensed artificial insemination centres at Cambridge and Kaiapoi. A total of 50 bucks have been trained for semen collection, with the training period varying from 5 minutes to 2 weeks. Collection from some individuals began as early as December, and continued until August. All semen used was frozen in a Tris-based egg yolk/glycerol diluent. Semen quality has been determined by post-freeze motility using a 2 sec photomicroscopic technique. Training courses lasting for 3 d have been held to instruct both visiting technicians and owner/operator type inseminators. In combination with Ambreed technicians operating directly from Cambridge Centre, approximately 15,000 goats were inseminated during the 1987 autumn period. Kidding data are currently being analysed and indications of pregnancy rate from non-return rates are currently in the 50-55% range.
