Bullit; where are you located? the biggest thing is are you going to have a dozen or so calves to sell at a time or are you going to have 50 that you can market them for their "special" qualities. What sells in your area?
I will try to keep this short but everyone knows I get into explanations. Here in Va black is king and black baldies are very good. Anything red, limis, our red polls, and including red angus, takes a hit. Char crosses that are smokey WITH A BLACK NOSE will do nearly as good. Shorthorn, straight herefords, straight char with the pink noses, speckled calves, will take a hit and GOD FORBID it has any ear on it......dum de dum dum.....
Dairy steers will run .80 to 1.00 a lb year in and year out. Dairy crosses will do maybe a little better but if it has the "fineness" of dairy, especially jersey, then it is considered dairy. Due to the large number of dairy farms, holstein steers have their niche and some former dairy farmers do well feeding out holstein steers. Still, they are dairy.
I have several dairy and dairy x cows. I like my dairy and milking cows, and have been involved with dairy most of my life. We also run a commercial beef farm and have mostly angus and crosses and have some herefords, some red cows, and char x and even a few speckled park. We sell a few sides of beef and always use our "odd" colored calves for beef.
Right now I have 4 dairy cows as nurse cows in the barn ; a jersey, an old guernsey, and 2 that are 3/4 jersey 1/4 holstein. the jersey has 2 good teats and has 2 calves, and an attitude problem that has determined this is her 2nd and last time as a nurse cow; the guernsey has 2 (and a third one partly on her) calves on her; one of the 3/4 jerseys has 3 good teats and has 3 calves on her. The other 3/4 jersey has 3 - 4 month old calves on her and she comes in because she is a first calf heifer and can use extra grain, and takes the 3rd calf from the guernsey and it nurses her also. I am weaning her 3 older calves and this cow will let anything nurse her; so she shares the one with the guernsey, and I caught 2 of my bottle babies also nursing her. So as soon as I move her 3 older calves I will let her feed whoever she wants. I also have 3 "bottle babies". And as I said, I have caught 2 of them stealing off the nurse cows while in the lot during the day.
You have to have a market for the calves; or understand that you will get less for the calves. But, I figure it this way; and this is just a general average on an average year. A good beef cow will produce one calf. At 500 lbs, that calf is worth say 1.50 lb. S750.00. Costs in the neighborhood of $450. to keep the cow. These are average figures..... So if you are lucky you make $300. over the cost of keeping the cow. Take out death losses, all other stuff, add another $100 in costs, so you make $200 per calf.
My nurse cow has a beef cross calf. Weaned at 400lbs at $1.00 lb that is $400.. She raises 2 additional calves. Same deal, weaned at 400 lbs @ $1.00 equals $400. each. She has produced $1200 worth of calves. I paid $50.00 each for the additional calves, so $100. She gets grain for the first 4 months so an additional $200 to feed her. So, it is costing 450 plus 200, plus 100 for 2 additional calves. If you figure the additional 100 for various extra costs that is $850. on the cow and she has produced $1200 worth of calves so I am making $350 per cow....
My thoughts are that 2 calves pay for expenses and the third calf is profit.
This is figuring on the average to low side of returns for the calves when weaned. Any pure jersey calves will sell as good as a holstein in the spring at 500 lbs or so for people who know jersey beef and want something to run for 6-8 months on their back few acres and put in the freezer. I get 1.00 lb for jersey steers right out of the pasture. More when I sold jersey beef delivered to the butcher. But then you are dealing with the "john q. public" and that can be a pain.
Any 1/2 dairy 1/2 beef heifers I raise up for cows. They will milk and raise a real nice calf. Bred beef the calf usually will look pretty beefy ( it is 3/4) but occasionally they will show more dairy. Some of the 1/2 dairy cows will have too much udder and I will put a second calf on them and grain them some for 6-8 weeks til the calves get going real good and so the cow won't lose too much condition. Then she goes on pasture with the rest of the beef herd and the 2 calves are hers. They will often wean at 4-500 lbs, and so will bring 800 to 1,000 for 2 calves at the 1.00 lb. Anything more is just gravy.
If you like fooling with dairy cows like I do, it is a way I can have my milk cows and not be stuck into a 2x a day milking or going full dairy and all the b.s. that is in the industry. I breed some AI so can get dairy calves out of my better cows and 1/2 beef out of the others. There are some that have lousy dispositions, some that once you get an extra calf or 2 on them they are their calves, and don't mess with them; and some that will let any and all that want a meal to suck.
I get my calves DIRECTLY off a dairy/dairies and I know they have had colostrum. Yes it helps that I am a milk tester and have sources. But, many dairies around here have someone that gets all their calves. Pay a set price, big, little, twins, the buyer takes them all. It averages out and the dairy farmer doesn't have to deal with making a trip to the market and all the hassle. Most dairies that you develop a relationship with will make sure that the calves get a feeding or 2 of colostrum, because you will spread it around if they sell sickly calves that always die.
There are other little tricks to the trade but this is long enough for now....
