Abstract

The Ministry of Agriculture and Fisheries in New Zealand began a major Beef Breed Evaluation (BBE) as from the mating year of 1971. Widely sampled Angus (A) and Hereford (H) cows have been used to generate test progeny for carcass evaluation (steers) and reproductive comparisons (heifers : 4 calvings and 5 mating years each). The work is spread over three stations, the majority of cows being in the most difficult environment, Goudies Research Station, about 50 km south-east of Rotorua in the central North Island. The present summary is for Goudies-bred heifers barn in 1973 to 1977, out of nearly 200 artificial insemination (AI) bulls of eleven breeds. Four breeds are local, Angus, Hereford, Friesian and Jersey and seven imported, Blond d'Aquitaine, Charolais, Chianina, Limousin, Maine Anjou, Simmental and South Devon. Bulls were chosen as being the best available from each breed, based on growth performance or progeny test data.
