Decoquinate should be added to calf starters. Due to low and variable starter intake, coccidiosis prevention can be compromised. Once calves are weaned and their rumens are functional, shifting to an ionophore can prevent cocci and improve feed efficiency. Monensin has received label clearance for the prevention and control of coccidosis in confinement animals. Pelleted protein supplements avoid fines, dustiness, and separation problems.
Research results with higher levels of undegraded protein and fat are variable.
Field response to heat-treated soybeans has been encouraging. The use of a nipple bottle feeder for calf starter can encourage early intake, but waste can be a problem. Forage should be fed prior to weaning. Haylage can replace hay if it is fresh, palatable, and mold-free. An optimal dry cow feeding program is critical to calf survival and development.
