This is the type of post that you can come away with "2" possible end results.
1) Be tactfull and diplomatic, and possibly end up being liked and well thought of -- OR
2) Just be honest and stick a foot and half your leg into your mouth --
I am going to try to be some place in between~~ hehehe
First off -- THANKS to SRU for that nice refferal -- we sure enjoyed having Shae here last year -- all in all she did you pretty proud! Thanks SRU!!!
JIT has made some VERY good points, and I see most of them all the time. In my own herd , we had a cow we called Gramma -- I swear you could squirt the semen at her as she walked by you and get her bred, and back up WEEKS doing it. We decided to flush that good cow -- and as JIT said you just never know. You would feel as though that cow would be a gangbuster donor seeing how fertile she was -- WRONG. Believe me folks, fertility takes a whole new twist when it comes to the "Physiology" end of reproduction. I have deffinately noticed that the cows who appear to be the best looking with fertile history hardly ever make the best donors. Those cows who may not stand out in the herd, but produce better calves then themselves every time are your best GENETIC donors, but then may not be good egg producers either. Gramma flushed twice, with 2 and 4 eggs. She them promptly re-bred every year after and gained at least 2 weeks per year doing it! Go figure!
Year in and year out, I am amazed at how a cow who would not breed A-I, failed to the bull as well, and then because she made such good calves came in here as a donor. Almost every one of those cows would CRANK the eggs out -- with apparent ease. It is still after all a game, and the odds are in the favor of the cow! We can make changes as JIT said, but only to a point. They do have to help us out -- most of them do ust fine, others are a real frustration for both owner and me as well!
NOW -- (Inserting foot) After many years in this fine business, I must admit that I have had quit a few Shorthorns come here, and with the exception of a few -- they just never did AVERAGE as well as other breeds do. Especially the clubby bred type -- if they are really thick and muscular looking, it almost takes help from above to get them to work out right. Although I have had from -0- to 32 on Shorthorns, the average will be closer to 5-6.
Some breeds (Simmi's for example) need to be low dosed or you get huge responses, with most of them being bad from lack of ability to either fertilize or just take care of them. They have to be handled easily dose wise or you could flat destroy the cows. Any one ever felt an overy the size of a football???? I went to a place once where the owner decided to do it HIS way -- using his neighbors tips to super the donor. He never told me till later he had failed to use my dose schedule. I got ready to flush his cow - a Sim-An 5 year old -- and when I reached into her there was NO ROOM for my arm for all the ovarian size in there. I almost fell over with shock -- embarrassed as heck thinking I had really screwed her up! She would have had OVER 50-60 eggs - meybe even 100, but she had no chance to ever get them collected. I managed to fully flush that cow, and I only found 11 eggs -- ALL unfertile. What happened??? The overies bascily imploded -- the fimbria (Funnel around the ovary that cathes the eggs) could not expand large enough to even begin to collect them all, and for that matter -- were so stretched out of shape -- she was going to be permanently scared over -- she never rebred either.
I looked at that guy like I was waiting to be shot -- THEN he told me what he did -- my first reaction was anger -- I actually yelled at him for a few seconds, then I stopped and simply said -- I am sorry your cow could be sterile, I am sorry you didn't listen to me -- and I hope you call a different guy the next time. That is totally uncalled for folks, he simply did not know what he was about to do by listening to his Einstein neighbor -- he called a year later and apologized!!
Back to story -- Shorties -- on AVERAGE -- will be somewhat less productive in ET than some other breeds, but that does NOT mean that they do not do well. Some times we can PLAY with them like JIT said, and hit thier hot spot. Some just do not flush well at all - ever. I will let SRU tell his story if he feels the needs here -- it was interesting right ??
One thing I must add here is this -- I always ask if possible, that the donors can come here fo rme to work with. I have a rather unique way of doing them, and I have NO problem breeding them at 2 in the morning if need be. I breed ONE time, using 2 units of semen. Timing is everything for fertilization, and here at least -- the donors are 100 feet form my bedroom window!!! hehehe So my point is this, even with a rather smaller number of eggs, if you don't get there on time, you won't even getr them fertilized. With rare exception, we very seldom have a bad batch of eggs from these cows. Alot of things go into this, so if any ony one is a little under experienced at it -- it can get frustrating REAL quick!
This why I get called WINDY on occasion, so I will stop here -- probably didn't even answer your question but ut was fun trying! Better luck on your donors from here on -- smile JIT -- that cow of yours in unique!
