so not worth the hassle? would it not increase profits by a fair bit?
It's a serious hassle to put a new calf on a cow who has lost her calf. Sometimes it will work, but sometimes it will fail. The cow will puck hell out of the new calf. You'll have to hold the cow in a crush or gate for several weeks in order to get her used to the new calf. Even when you think that the cow has taken to the new calf and let them out to grass you will often find that the cow won't let the calf suck.
If you were going to double suck, then the best option would be to have the second calf on hand when the cow is calving. Tie his legs and have him lying down. Cover him in the cow's fluids - water bag fluid, after birth etc. and lay the 2 calves in front of the cow's head to let her lick them and think that she calved both of them. Leave the calf tied until the cow's own calf has sucked and claimed his share of the beastings. It's a lot of work though and can be dangerous. Then 2 calves sucking a cow can be very hard on the cow - if she is a good milker she will burn the fat off her back to keep the 2 calves supplied with milk. She could get poor and she may struggle to go back in calf.
A story for you. I was selling a bull at a sale last year and the guy with the bull in the stall beside me started talking about his bull and asking about mine. Mine was a nice young bull, off a heifer, but she had lots of milk. His was the same age as mine, but looked unreal. really well fed and filled out. He told me that when his was born, the cow had no milk at all, so he had to buy a dairy cow for €1500. All he wanted to talk about was money. What did i think my bull was worth, how much it had cost me to put him this far? I told him that I would be happy selling mine at €2500. I'd have €700 or €800 out of him at that. He said that he needed €3000 for his because he was a better bull than mine. I said surely you'll need more than that to have him clear. Not at all he said, I'd be clear at €2000. He got mad with me when i went through my figures and then went through his:
€600 for feeding my cow for the year. Bull ate €600 worth of meal. Testing, grooming, ai straw, transport etc.
For yer man: €600 for feeding the calf's mother. €1500 to buy the dairy cow which didn't go back in calf and got very poor and was valued at about €800 at this stage, €600 for feeding the dairy cow. Meal €600. testing, grooming, ai straw, transport, etc.
My bull cost me about €1800. His bull cost him €3000 to get that far. He was raging mad with me for pointing out these figures to him. Anyway, it was a poor enough sale and I let mine go for €2200. He was in the ring just before mine and got the top price of the day for Limousin Bull of €2500.
He got his picture in the paper, but it cost him at least €500 for the pleasure.
Cattle are not always what they appear to be.
