| Abstract: | Based on the beneficial trait, which is defined two component traits making up feed efficlency by price. A method for drawing up selection index aiming at improving feed efficiency is discussed in this paper. It avoids so many troubles from directly selecting feed efficiency,simultanously, settles the questions to draw up selection index for the kind of ratio tralts, |
