Results of commercial crossbreeding experiments in 1978-1980 with heifers of different breeds. 1. Calving characters and fattening performance



Results of commercial crossbreeding experiments in 1978-1980 with heifers of different breeds. 1. Calving characters and fattening performance



Schweizerische Landwirtschaftliche Monatshefte 59(3): 57-65



Groups of Swiss Brown (SB), Simmental and Fribourg heifers were inseminated with semen of SB, Simmental, Herens, Aberdeen-Angus (AA) or Limousin bulls. Calving performance, and growth and meat yield of the progeny, were analysed from the economic standpoint. Bulls belonging to the 2 first-mentioned Swiss breeds had been progeny tested, and had a negative breeding value for milk and a positive breeding value for meat.
