[QUOTE="Idaman, post: 804543, member: 14119"] These cows were linebred for 130 years, at least 40 years longer than the L1s without ever having any genetic defects so that is probably not the reason they almost went extinct. There were lots of Hereford lines that either went extinct or nearly so in the size rush of the 80s. Colorado Dominos, Zato Heirs, Onwards, and I could go on all night. These cattle had just been through one of the worst winters in recent area history and at least 6 of their former herd members died in that winter. The owner simply didn't have the funds to take care of them. The 1600 mile haul plus a 7 day breakdown in 100 degree weather and the change in climate were the culprits as they arrived with the pnuemonia. After we cleared the pnuemonia we immediately flushed them and got a surprizing number of No.1s. The one that foundered had the most lung damage from the pnuemonia and has been very delicate ever since. The ET center located closest to where these cows came from said in their history they had never had as bad luck as the spring following that winter. By mid summer their success rate returned. She foundered on very good straight grass pasture. The day we gave the first Lute shot we had to remove them from a semi wet soft ground pasture and drive them down a gravel road where we had set up a special corral and breeding box for their stimulants and AI service. 24 hours after that drive 2 came down with footrot. We called the ET vet and he said that they probably wouldn't breed but we could try to salvage something with CIDRs which we did. One fot rot sufferer flushed 5 eggs and the other one had failed to come in heat although she had produced in an earlier flush. They have survived against incredible odds and conditions which makes me have tremendous faith in them. Not only the above but every one of them were produced by a cow that was at least 11 years old al the time each cow was born. If these conditions are the ones of a pampered donor then I need to start all over after 60 years. The point however remains that with very small numbers you can have some very unique challenges.
