[QUOTE="inyati13, post: 1001494, member: 17767"] GRF, think of it this way, for the uterus or vagina to prolapse there has to be a weakness in the connective tissue, anatomy of the organ or physiology of the reproductive system. It would be easy to say that the prolapse is due to a failure of the connective tissue, etc. But the deeper analysis would be that the failure is the result of genes that dictate how the connective tissue is formed and built into the cow. Thus, in the end, there is a snip of DNA that is not doing a good job. Your vet may be correct in so far as saying the uterus prolapsed because the connective tissue that holds it in place failed. But remember, those chemicals that make up that connective tissue are coded in the DNA in the nucleus of the cell. Messenger RNA carries the information to the cytoplasma of the cell and instructs the cell how to make the building blocks of the connective tissue. If that DNA does not transmit a high quality message, then the connective tissue is not as good in the cow that prolapsed as it is in the cow in the next stall that does not have the compromised DNA snip. The cow you reference probably has genes that do not do their job well. I know this is not written as you would get it from a molecular biology or cellular physiology text but the idea is there. Hope I made it clear enough that the message comes across. [/QUOTE]
