Kansas Agricultural Experiment Station Research Reports
Two trials were conducted to evaluate the effect of high dietary levels of trace minerals on performance and health of stressed calves. In trial 1, 221 Brahman crossbred steers (674 l b, 1/8 to 1/4 Brahman) were used to evaluate the effect of copper (Cu) and zinc (Zn) supplementation on performance and immune response. The steers were shipped from northern Texas to the KSU Beef Research Un it with an 18-hour transit time.
