Effects of differences in size and mean genetic value among contributing flocks in group breeding schemes

Effects of differences in size and mean genetic value among contributing flocks in group breeding schemes

Proceedings of the Sixth Conference, Australian Association of Animal Breeding and Genetics, University of Western Australia, Perth, WA, Australia, 9-11 February 1987: 328-332

Computer simulations were performed for 4 groups of wool sheep, each involving 4000 breeding with an initial overall mean breeding value of 3 kg for greasy fleece weight. Ten discrete generations of selection were simulated. Each group contained 8 flocks (initial differences between flocks being entirely genetic), one of which was the nucleus flock (containing 12.5% of all. The nucleus flock received 7% of from each contributing flock.
