Nutrient Mass Balance And Performance Of Feedlot Cattle Fed Barley Based Diets In Large Pens In Western Canada, Erin M. Hussey
Department of Animal Science: Dissertations, Theses, and Student Research
Three separate large pen commercial feeding trials with approximately 9,000 heifers with either eight or ten reps/treatment were conducted at a Western Feedlots Ltd.- High River, a commercial feedyard near High River, AB, Canada. For all three experiments, Near Infrared Spectroscopy (NIRS) was used to segregate feed barley. In Exp. 1, barley was segregated based on digestible energy (DE) content as predicted by NIRS and heifers were fed low or high DE barley, or a 50:50 blend of the two. Feeding low DE barley improved weight gain, dry matter intake (DMI), and mortality; with little effect on carcass composition compared …
