Several questions raised... I'll try to fill in the gaps.
First off the cow was prolaps... uterous comes out during a difficult calving, in this case breed too small to a bull too big & the calf had its hoofs in the wrong place to come out right. Means the animal is not going to live without extensive surgery that most rancher are unwilling to mess with, because she is likely to do it again. Don't know what the process would be to sell it to a dog food place. People who have this herd... well they don't need the money, lets put it that way. So a gift cow to the preacher or a couple of $$ from the rendering truck, neither will effect their top or bottom line noticably. (& no they are not members of my church, just great people who approve of the work we are doing.)
After I was done I took the 4 quarters to the local High School which has a meat cooler (FFA makes a few bucks every fall come elk season). The FFA teacher is a friend of mine & so he hung the meat for me very close to a week. The $50 is a gift back to the FFA for hanging & then the boys cut it up for me. (actually $25 & a pizza, but who is counting?)
I got the meat back from them today. Our grinder is not here yet (finally got to order our own) so the meat was just frozen in ziplocks. Ended up with 152 lbs (+/-). 1/3 of live weight rings about true to me. Biggest whitetail I've shot gave me 83 lbs of meat and live weight was over 200 lbs for sure. The school will only bone out, no bone cutting, so no ribs, no fancy steaks, etc. What we need though are roasts and ground beef so this works great for us. I think if I was to do the boneing / ribs & stuff the actual useable would have been up just a tad, maybe 200 lbs = 600 lb live weight. Not sure how detailed the boys got I guess, but I'm not complaining either.
As to the quality... we had the first roast tonight. Having lived most of my life in good beef country South Dakota, I have tasted the whole range of good to bad beef. Honestly I was concerned what 2 days of prolaps would do to her. This roast was never frozen. Small roast, maybe 2-3 lbs. We put it in a marinade for 2 hours just to be sure & then slow cooked it at about 350. No worries, it was good. Not "cut it with a dull spoon & watch it fall off" good, but a crockpot would make it that way. It had a nice consistency, solild, but not chewy. Taste was fine. Certainly not the highest quality ever, but absolutely no complaints either! Next one will not get masked by marinade.
God Bless,
