BACKGROUND To reduce the environmental impacts of the aviation sector as air traffic grows steadily, the aviation industry has paid increasing attention to bio-based alternative jet fuels (AJFs), which may provide lower life-cycle petroleum consumption and greenhouse gas (GHG) emissions than petroleum jet fuel. This study presents well-to-wake (WTWa) results for four emerging AJFs: ethanol-to-j...

Two randomized complete block design experiments with a factorial arrangement of treatments were conducted to study the effects of corn processing method and inclusion of sorghum wet distillers grain plus solubles (SWDGS) in beef cattle finishing diets. In Exp. 1, 160 crossbred steers (primarily British x Continental breeding; initial BW = 397.6 +/- 29.4 kg) were fed diets based on dry-rolled (...

Corn gluten meal (CGM) is a major coproduct of corn wet milling; it has value because of high protein. However, variation in composition and high P content reduce market value. Data that characterize gluten streams would be helpful in identifying key processing steps that could be modified to improve the quality of CGM and increase processing efficiency. Few data are published in the literature...

Two experiments were conducted to evaluate combinations of wet corn gluten feed (WCGF) and barley, as well as the particle size of dry-rolled barley and corn, in finishing steer diets containing WCGF. In Exp. 1, 144 crossbred steers (initial BW = 298.9 +/- 1.4 kg) were used to evaluate barley (0.566 kg/L and 23.5% NDF for whole barley) and WCGF combinations in finishing diets containing 0, 17, ...

Feeding increased concentrations of distillers dried grains with solubles (DDGS) to ruminants has been avoided due to risks of S toxicity and concerns about animal performance. The objective of this study was to evaluate the influence of feeding an increasing concentration of DDGS and corn processing method on animal performance, incidence of polioencephalomalacia (PEM), and concentration of H(...

Lambs were assigned to a 2x2 factorial design with corn or barley fed either whole or rolled. Hay was fed for ad libitum intake while concentrates were fed in similar amounts. Dry matter intake of hay, ADG, the gain:feed ratio, and warm carcass weight (WCW) were higher (P<0.05) for lambs fed corn than for those fed barley. Cereal processing had no effect (P>0.05) on hay dry matter intake, ADG, ...

Two hundred sixty four yearling heifers (781 ± 35 lb) were blocked by weight in a 2X2 factorial arrangement of treatments to determine effects of 20% corn wet distiller’s grains plus soluble (WDGS) on animal performance in steam-flaked corn (SFC) and dry-rolled corn (DRC) based finishing diets. No corn processing method by WDGS inclusion interactions were detected (P ≥ 0.29). Heifers consuming ...

Several experiments were conducted to evaluate the variation in nutrient content and digestibility among different commercial samples of DDGS, the effects of different processing methods and feed additives on the bioavailability of P in DDGS and the effect of new processing technologies on the nutritional value of DDGS for poultry. The nutrient composition varied substantially among DDGS sample...

Determination of available lysine was used to assess the heat damage produced during the processing of cereals for infant foods. The infant cereals analysed were: wheat, 7 and 8 cereals, rice, rice±corn, rice±corn±soy and oat. Lysine losses during the toasting of ̄ours ranged between 14 and 29%. Roller-drying treatment caused considerable heat damage, with a 53% decrease of available lysine in ...

Corn silage is a major forage crop in Idaho, supporting its dairy industry. Corn silage produces more digestible energy per acre than other forages. Nutritionally, corn silage is palatable when ensiled properly, and high in energy because it typically contains 50% corn grain. Digestibility of starch declines as the kernel matures. Effective roller processing of corn silage ensures that most of ...
