This causes a large economic loss because calves can efficiently convert feed to gain at this age. Also, heifers that will be bred as yearlings only have approximately five months before breeding, and must get off to a good start at weaning.
Many feedlots use high energy receiving rations for calves shipped from Florida.
Many Florida cattle producers do not use high energy weaning feeds because they are concerned with acidosis and health related problems developing in the calves. However, high energy feeds can be used successfully with favorable economics because high roughage and high energy weaning feeds are often sold for a similar price. Each group was placed on a one acre bahiagrass pasture. Pastures were not fertilized, and forage availability was limiting. Two groups each were assigned to a high roughage or a high energy feed.
