I had 5 cows calve within the last month and 3 of them seem to be getting really thin, calves seem to be harder on them this year for some reason, 2 are 3yr olds 1 7yr old they get grain, pasture( even though its just starting to grow) saving the other pasture for hay, sweet feed. I feel like Im lacking mineral. I have heard Mineralyx is a good one. I like the like tubs. Now and then been throwing the girls some alalfa, plus they get round bales. When can you worm with new calves? What else or different should I feed? :???:
