| Abstract: | Some measures in selection and assortative mating were discussed in this paper. In order to avoid inbreeding depression, the sum of generations which is from mating pairs to common ancester should be above 6. The coffecient of inbreeding should be controlled strictly under 4 %. Those measures could prevent cattle population depression and increase productive levels entirely and gain the best benifit. |
