摘要

BEEF BREEDING practices usually focus on producing bigger market animals, a management strategy that means heifers kept for reproduction end up heavier than needed, say University of Guelph researchers. They've found that certain sires can produce calves with different weights, based on gender. And through breeding, they say the best sires for this trait could be picked. Prof. Jim Wilton, Department of Animal and Poultry Science, says cattle breeders will soon be able to select for increased steer weight without increasing heifer weight. This improved raale-to-female weight ratio means farmers can minimize costs, by avoiding having
