Abstract
The Artificial Insemination organisation of the Milk Marketing Board (MMB) (now Genus) progeny tests approximately 100 Friesian/Holstein bulls each year in co-operating milk recorded herds. In 1983 a linear assessment evaluation scheme was introduced in order to describe the conformation of animals in a more objective way. In conjunction with the Holstein Friesian Society it was agreed to score 16 main traits in the assessment scheme. The MMB also included a seventeenth trail, Beef Shape. The linear assessment scores are analysed by Best Linear Unbiased Prediction to provide sire evaluations on the bulls in the progeny testing scheme. The purpose of this study was to evaluate the environmental and genetic parameters for the traits assessed in the scheme during the first two years.
