It is less desirable, but acceptable, to vaccinate at weaning. Discuss the best vaccines for your operation with your veterinarian. Calves should be dewormed at least once prior to weaning and again at weaning time. Another idea to minimize stress at weaning is to creep feed calves for a short period prior to weaning. Attempt to limit the creep feeding level to about 0.5 to 1.0 percent of body weight, if possible.
Creep grazing is another option that has been reported to ease the stress of weaning.
Growth-promoting implants are another important way to improve calf performance prior to and following weaning. Calves to be sold in commercial markets will often receive at least one implant early in life and another prior to or at weaning. Good Facilities are Essential. Provide working corral, chutes, alleys and sick pens that permit easy sorting and handling during the weaning period. Quiet and quick handling not only reduces the labor required, but also reduces stress.
