METHODS TO INCREASE PRODUCTIVITY IN NEWLY ARRIVED STOCKER CATTLE

This project seeks to evaluate methods that can increase overall productivity in growing beef stocker cattle.The stocker cattle industry is comprised of newly weaned beef cattle that are grown for a period of time using inexpensive feed resources (pasture and byproducts) prior to entering the feedlot finishing phase (Peel, 2003).In some instances, these animals have been mismanaged prior to weaning (males left intact, poor or no vaccination background, inadequate or unknown pre-weaning nutrition), and steps will need to be taken to add value to these animals (Beck et al., 2013).This project will examine use of direct fed microbial as well as some management strategies (castration methods, forage management, and supplementation decisions) and their effect on the health and performance of stocker cattle.Objective 1.Determine the effects of direct fed microbials on performance and health of cattle received in a dry lot or on pasture.Objective 2.Determine the effect of castration method (banding versus surgical) with or without analgesic on DMI and performance of beef cattle.Objective 3.Determine the effects of backgrounding system (drylot or pasture) on health and performance of newly received beef cattle
