Fall born replacement heifers have been (or soon will be) weaned and will be at a very critical growing period. It is important that they grow at about 1.5 pounds per day from weaning until the start of the breeding season. Currently summer pastures are green, growing, and adequate in protein content. However, warm season pastures such as native grass or bermudagrass can be expected to be declining in forage quality in the hot, dry days of July, August, and September. Also these grasses will be reaching plant maturity which accelerates the decline in protein content.
