Since 2004, fertilizer prices have doubled due to increases in energy prices for production and increased demand for N fertilizer due to high grain prices. This leads to questioning the cost effectiveness of increasing forage production with N fertilizer. At the same time, an increase in ethanol production creates an increase in the production of by-products of the ethanol industry, such as distillers grains. Distillers grains have been shown to be an excellent feed for ruminants both as a supplement while grazing and as part of a complete diet in the feedlot. Distillers grains provide protein, fat, and highly digestible …

The objective of this experiment was to evaluate the effect of a beef animal’s physiological status on forage intake. The experiment was repeated over two years with six replications of three treatments per year: cow-calf pair (CC; BW = 629 kg), dry cow (DC; BW = 503 kg), and yearling steer (S; BW = 305 kg). The cow and calf were treated as one unit, with cow BW and calf BW comprising CC BW. Calves were approximately 42 d of age and weighing 73 kg at the start of each year. Animals were housed in individual pens and fed high …
