Replacement Of Grazed Forage With Wdgs And Poor Quality Hay And Straw Mixtures, Sandra B. Villasanti
Department of Animal Science: Dissertations, Theses, and Student Research
A grazing study was conducted at the University of Nebraska Gudmundsen Sandhills Laboratory from mid-June to late-August across two years (2009 and 2010) to evaluate the effects of supplementation with mixtures of wet distillers grains (WDGS) and straw or hay on grazed forage intake. Twenty 1 ha paddocks replicated over two blocks were randomly assigned to one of four treatments: Control (CON) at the recommended stocking rate (1.68 AUM/ha in 2009 and 1.64 AUM/ha in 2010), and three double stocked treatments supplemented with 60% straw and 40% WDGS (STRAW), 60% hay and 40% WDGS (LOW), and 70% hay and 30% …

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 …
