Cattle weights can be highly variable and are influenced by many factors, including time of weighing, ambient temperature, feed intake, and cattle handling. A protocol of limit feeding has been in use since the 1980s that was designed to reduce variation in gut fill due to differences in intakes. Cattle are penned and fed a 50% hay, 50% wet corn gluten feed(More)
Smooth bromegrass pasture beef growing systems: Fertilization strategies and economic analysis" (2012). ABSTRACT In recent years, prices for N fertilizer have increased dramatically, reducing net returns of fertilized pasture systems. A 5-yr study from 2005 to 2009 was conducted to evaluate management strategies and relative differences in profitability for(More)
"Comparison of wet and dry distillers grains plus solubles to corn as an energy source in forage-based diets" (2016). ABSTRACT Four experiments compared wet or dry distillers grains plus solubles (WDGS or DDGS) to corn as energy sources in forage-based diets. In Exp. 1, 66 individually fed steers (268 kg of initial BW) were fed a 60:40 blend of sorghum(More)
Increased corn prices over the past decade have altered land use away from traditional forage in favor of corn. Accordingly, beef and dairy producers have had to adopt nontraditional forage resources into their production systems, many of which have become available as a result of increased corn production. Corn residues have become more available due to(More)
Chlorella sorokiniana CS-01, UTEX 1230 and UTEX 2714 were maintained in 10% anaerobic digester effluent (ADE) from cattle manure digestion and compared with algal cultivation in Bold's Basal Medium (BBM). Biomass of CS-01 and UTEX 1230 in ADE produced similar or greater than 280mg/L after 21days in BBM, however, UTEX 2714 growth in ADE was suppressed by(More)
1. Introduction Climate change due to anthropogenic greenhouse gas (GHG) emissions is causing a range of environmental challenges and corresponding mitigation policies (Karl et al., 2009; Ell-erman and Buchner, 2007). Global GHG emissions from livestock production were recently estimated to be 18% of an-thropogenic GHGs (Steinfeld et al., 2006), which is(More)
