[QUOTE="KNERSIE, post: 1044345, member: 4353"] ZMT, I'll try to simplify it as much as possible... Firstly you need an outstanding individual that approximates your ideal, usually it will be a well proven sire. You mate him to cows that will address weaknesses the sire might have (the more uniform the cows the faster the results) You continue breeding this same sire to the same cows for as long as he is available. The resulting calves will be halfsibs. You use the best of the halfsib bulls and breed it to his halfsib heifers with the hope to produce a better bull than himself or his sire. Once you find a good linebred bull continue to use him on his relatives until he outbreeds himself and give you yet a better bull prospect. The ideal is to concentrate the already good traits of the original sire by keeping his 50% influence consistant through halfsib matings. Don't exceed that 50% influence if you can help it, as 50% is the natural relationship an offspring has of each parent. The crux of the matter is to cull hard, use only the best bull calf and don't keep any heifers with faults or undesireable traits. Remember you'll eventually get everything that you've specifically selected for AND THAT YOU DIDN'T SPECIFICALLY SELECTED AGAINST! The good thing is you can still sell your culls at market value making the risk much smaller as is the popular believe. [/QUOTE]
