I kind of got lost in the translation...but...i think i got...first time calver, no milk in the front...right wrong...let me know
anyhow, some new mommas are real tight on sharing the milk with the milker. Some things which work to get them to drop the milk...and i prefer one over the other...
a shot of oxytocin 5-20 minutes before milking. Never seen a cow or heifer able to hold milk with this...vet recommended...works like a charm. If there is milk in there, she will have not choice but to give it up.
The second, and i have never tried it, but i am told it works well...a crack over the head...the guy who told me said he used a hammer. My first thought was give me a hammer and lets see if it works on you...Anyways the idea is to give her something else to think about other than holding the milk. I'm of the personal opinion that once you start milking her she will more than likely give you something to think about for a long while.
If she is a dud in those quarters after the oxytocin, your best bet is to ship the cow post weaning. It is a good chance that this cow puts the energy into herself rather than the calf. This would be evident by the cow being in the best shape or close to the top in the herd of the best shape even if you are in a drought area. That feed conversion to calf might not be that good and there is a good chance the two fronts could be full of fatty deposits. This means, in a year or so, her breed back will also be affected because a good condition, or rather over conditioned cow will not come around as regular as a decent condition cow with a decent calf. A calf should be between 50-60% of the cow's weight at wean time.
Now i understand that the drought will bring the cow down in conditon, but compare her with the rest of your herd. If she is in better shape than the rest, and if her calf is either the same or of poor quality...she is and will always convert the energy for herself before her calf.
The other thing is, how did you feed her when she was a weaned heifer? Heifers which have been fed heavy hot feed from weaning to breeding have a tendancy to develope this energy conversion crapper more often than not. Pushed fed overconditioned heifers will not breed back on time once that first calf hits the ground. And usually by year 4 is on the cull list.
We have not experienced drought like you have. But we have experienced feed shortages due to overland flooding, and in my book that is just as bad. We had to cull out alot of the cows due to the feed shortage since we were not willing to buy. The one thing the vet said when we preg tested...get rid of the poor converters. The ones who put it into themselves and not the calf. If feed shortage is your problem, then get rid of the free loaders.
