Hey there Red -- I see you are thinking --that's GOOD ! hehehe
Bottom line for these two products --
1) Lutelyse -- a prostoglandin product derived from natural sources - those things that occur naturally in catlle.
Dosage -- comes in a 30 ml - "6" dose bottle -- thus giving you a 5ml injection per dose. Dinoprost Tromethalene (SP) is the drug in the mix.
Will at times cause the cow to fail to ovulate OR fail to fully regress the CL on the ovary due to over use or lack of repsonse. Most cows do work well with this, but over doing it will reduce the efficacy of the product some what.
2) Estrumate -- a prostoglandin product derived from "Synthetic" sources, in other words -- made in the lab.
Doseage -- this comes in a 20 ml bottle -- with "10" doses per botle -- meaning you use 2ml per dose in stead of the larger 5ml for Lutelyse.
Cows can not -- "NOT" - get immune to the synthetic formulation used here, unlike the natural form of Lutelyse.
Ovualtion will almost always be of a better , more rapid and full regression of the CL and thus result in better release of fllicular fluids and the supporting structures of the follicle. In other words, I feel it just works better over time and with many many cows. If you check the Cl's like we do in ET, the cows from the Estrumate induction will have -- on average - a better quality and larger CL. Of course there are always excetions to that rule, you will still get a few that fail to ovulate -- but there is always a reason. Some herds are better than others for stress reduction and nutrition, and this is no different -- the better job we do going into it -- the better the result!
Now that everyt one is fully and completely confused -- I will simply say that I prefer Estrumate in my ET practice every time over Lutelyse, some times you just have to do alot to see the difference, but it is a substantial difference over time!
Hope all this helps you out there -- tell hubby not to worry -- I won't intentionaly brain wash you -- at least not competely!! hehehehe
PS - - DL thanks -- you were typing and posting as I was typing mine -- so if there is a major difference -- all I can say is -- OOOOOPS
Basicly we think the same however -- and my comments are from years of use -- not totally scientific, but in house, it has been pretty plainly written on the wall over time. In theory -- yes they should both be the same!
