Effectiveness of one- and two-stage selection of sires based on own performance and progeny test for a single trait: Selection of beef sires for 365-day weight



Effectiveness of one- and two-stage selection of sires based on own performance and progeny test for a single trait: Selection of beef sires for 365-day weight



Journal of Animal Science 55(1): 48-59



Theoretical methods are presented for estimating annual genetic response to single-stage selection based on the animal's own performance and to 2-stage selection based on own performance plus progeny test. These methods were applied to single-trait selection for 365-day body weight in beef cattle under the assumptions that h2 was 0.37 and the genetic standard deviation 15 kg.
