• Finish calving

• Keep calving area clean and well drained, move healthy pairs out to large pastures 3 days after calving
• Ear tag all calves at birth; castrate and implant male calves in commercial herds
• Give selenium and vitamin A & D injections to newborn calves
• Feed cows supplemental energy after calving; some protein may be needed also
• Keep high quality, high magnesium, high selenium minerals available
• All bulls need a breeding soundness exam at least 30 days before start of breeding season
• Fertilize pastures and hay fields according to soil tests

• Creep graze calves while on cows
