Distillers grains as an energy source and effect of drying on protein availability
نویسنده
چکیده
The use of distillers byproducts as energy sources would expand the market for these byproducts. Drying of these byproducts may produce changes that affect the nutritional value. A series of experiments was conducted to evaluate distillers byproducts as an energy source for finishing cattle and to compare wet vs. dried byproducts. The energy value of wet distillers byproducts was 132 to 174% the value of dry rolled corn for finishing cattle when the byproducts were fed as 40% of the diet dry matter. Distillers dried grains plus solubles were 130% the energy value of corn. Acid detergent insoluble nitrogen level of the dried grains did not affect feeding value. Distillers dried grains plus solubles were equal in protein value to wet byproducts when fed to growing calves. Acid detergent insoluble nitrogen level did not affect protein utilization of dried distillers byproducts.

Wet corn distillers byproducts compared with dried corn distillers grains with solubles as a source of protein and energy for ruminants.
Five trials investigated the feeding value of wet and dried corn distillers byproducts as a source of protein and energy for growing and finishing cattle and investigated the effect of heat damage on the feeding value of dried distillers byproducts. In a calf growth trial, no differences in rate of gain or protein efficiency were observed among calves fed wet distillers byproducts (wet distille...
متن کاملPreservation and Feeding of Wet Distillers Grains to Dairy Cattle
Distillers’ grains continue to be one of the most readily available co-products in use in the Midwest. Its price is driven not only by that of other concentrate feeds (such as corn and soybean meal) but also by supply and demand. Its popularity has increased in recent years among dairy producers, grain elevators, and nutritionists due to its high nutrient density, competitive price, and availab...
متن کاملEffect of Different Inclusion Level of Condensed Distillers Solubles Ratios and Oil Content on Amino Acid Digestibility of Corn Distillers Dried Grains with Solubles in Growing Pigs
The purpose of this experiment was to determine and compare the digestibility of crude protein (CP) and amino acids (AA) in full-oil (no oil extracted) and de-oiled (oil extracted) corn distillers dried grains with solubles (DDGS) with different condensed distillers solubles (CDS) ratios. Six barrows (29.6±2.3 kg) fitted with ileal T-cannula were allotted into a 6×6 Latin square design. Each pe...
متن کاملCan We Feed More Distillers Grains?
Distillers grains is a very good protein source (>30% crude protein) which is high in ruminally undegradable protein and is very good energy source (NEL ~1.02 Mcal/lb of dry matter; [DM]) for lactating cows and growing cattle. The modest fat concentration (10 to 12% of DM) and the readily digestible fiber (39% neutral detergent fiber; NDF) contribute to the high energy in distillers grains. The...
متن کاملUtilization of DDGS by Cattle
Distillers grains with solubles (DDGS), the major byproduct of ethanol production, is a good protein and energy feed for cattle. The DDGS can be fed wet or dried with animal performance usually similar when fed as wet or dried products; however, some research results favored the wet products. Cattle diets can contain DDGS as replacements for portions of both concentrates and forages, although D...
