[QUOTE="igrowgrass, post: 1079990, member: 21530"] I want to share this with all of you, because some people don't understand how genetics work on a basic level. Inbreeding, in and of itself, has no ill effect on cattle. Your cattle have a pool of genes. These are all the traits that are floating around inside the DNA. Some are dominant, some are recessive, some are co-dominant, some are other weird things. But basically, the pool contains all of the possible traits that your animal could pass on to its offspring. When you breed two animals together that are not related the pool of genes is vast and the bad genes are spread out all over the place. The chance of the bad genes, like infertility, lameness, etc popping up are very low. When you selectively breed your cattle for performance you are working hard to get all of the bad genes out of the pool. Scientifically, if you could get all of the bad genes out of the pool and you only had good genes for the cattle to pass on to their offspring you could breed brother and sister forever and ever with no ill effects. Thus, if you work hard, cull hard, and don't breed animals with any visible deficiencies you are strengthening and cleaning your gene pool. The cleaner the gene pool is, the less that in breeding will effect the quality of your cattle. In fact, if you have REEEEEEEEALLY high quality animals, line breeding or in breeding will actually help to "lock in" certain desirable traits. I think that people are geared to believe that all in breeding is bad. It isn't. Its only bad when the gene pool is dirty. I used to breed rats as a hobby. I owned pythons and started raising rats to feed them. Then I started breeding rats to sell to other people. Before you know it I was selling thousands of them per month. It became a business. They are mature at 16 weeks, and gestation is only around 23 days. You can go through so many generations so quickly that you can really see how all of this plays out. I have lines of rats that you can breed brother and sister and they will produce 10-12 identical offspring where all will be healthy and perfect. Its a matter of cleaning the gene pool before you start in breeding. [/QUOTE]
