Supplementing Distillers Grains In Extensive Beef Cattle Systems, Kelsey Rolfe
Supplementing Distillers Grains In Extensive Beef Cattle Systems, Kelsey Rolfe
Department of Animal Science: Dissertations, Theses, and Student Research
A 3-yr study evaluated effects of supplementing modified wet distillers grains with solubles during summer grazing and subsequent feedlot sorting on long yearling steers. During summer grazing, supplemented steers had greater ADG and were more profitable than non-supplemented steers. At feedlot entry, supplemented steers were 48 kg heavier than non-supplemented steers. Feed efficiency and DMI were not different between supplementation treatments during finishing. Supplemented steers were fed 24 fewer days to reach a similar 12th rib fat thickness, had greater LM area, and lower marbling compared to non-supplemented steers. Overall profitability favored supplementing steers because less expensive summer gains …

The effects of stable flies on growing calves were examined using fly cages attached to the animals. Dry matter intake, DM digestibility (DMD), and behavioral responses of calves were monitored. Nine Holstein calves were exposed to 3 levels of stable flies (0, 10, 100 flies/animal) 3 times daily for 30 min. The study consisted of a 4-period crossover design; each period included 5-d adaptation, 7-d exposure, and 5-d postexposure. Calves were weighed at the beginning and end of each period. Feed consumption was continuously recorded. Fecal samples taken during and after exposure were used to determine DMD. Three calves were …
