Feeds. A full feed of good-quality corn silage supplemented with protein, minerals and Vitamin A will produce from 1.5 to 1.8 pounds of daily gain on a 400- to 500-pound calf. Some grain additions will usually be needed to get 2.0 pounds daily gain.
How much weight does a calf lose at weaning?
Expect 500 to 600 lb calves to lose roughly 50 lbs at weaning. Even when a portion of that is gut fill, if those calves are managed to gain only 1 to 1.5 lbs per head per day during a 45-day preconditioning phase, we essentially get them back to where they started at weaning time – and that's about it.

Can you wean a calf at 3 months?
Some people feed the calves while others just wean them on pasture. Calves 4-5 months of age transition better, as they're used to eating forage.

Several years ago, we did some research in an attempt to reduce milk production in cows by “temporarily” separating weaning-age calves (7 months old) from their dams.
How long does it take for cows to dry up?
The number of days a cow spends dry has a significant impact on milk production in the following lactation. Cows need a dry period lasting between 40 and 70 days to allow for restoration of mammary gland cells. Drying the cow off should be done in time to allow this optimal length of dry period.
