Statistical analysis was conducted using analysis of variance for main effects of diet treatment, season and pen. The 80 day feeding periods were closely associated with summer, fall, winter and spring respectively. This project was supported by the North Dakota Agricultural Products Utilization Commission, North Dakota Waxy Corn Growers, and the North Dakota Buffalo Association. Results and Discussion Results by period are presented in table 2. As fed intake and feed costs per pound gain are reported in table 4.
Prices assigned are theoretical but reflect relationships in price of the commodities used.
Each producer will have to calculate his own feed costs based on local prices and feed intake of his animals. The relative cost of feed in relation to animal performance remains the major issue in all feedlot enterprises. Improved gains do not always offset increased costs. The relatively low cost of a screenings based diet is not always taken to greatest advantage if pelleting costs and feed waste are significant. References Anderson, V. L. and Dennis Sexhus.
