In a dry grind ethanol plant, approximately 0.84kg of dried distillers' grains with solubles (DDGS) is produced per liter of ethanol. The distillers' grains contain the unhydrolyzed and unprocessed cellulosic fraction of corn kernels, which could be further converted to ethanol or other valuable bioproducts by applying cellulose conversion technology. Its compositional variability is one of the...

Rate and efficiency of gain were not affected by adding as much as 20% distillers dried grains in isocaloric diets for nursery pigs or 30% in isocaloric diets for finishing pigs. These results demonstrate that the previously suggested maximums of 5% distillers dried grains in nursery diets and 10% distillers dried grains in finishing diets are too conservative. Finally, because the 20% (nursery...

This study compared diets supplemented with distillers dried grains plus solubles originating from whiskey distilling with those from fuel alcohol production or soybean meal. Forty-eight cows in mid and early lactation were offered a different dietary treatment in each of three 28-d periods. Dietary design included three supplements at 14 or 18% CP of dietary DM, with or without blood meal. Add...

Twelve multiparous Holstein cows averaging 57 d (36 to 77 d) postpartum at the start of the experiment were utilized in a replicated 4 x 4 Latin square design. Dietary protein supplements were 1) soybean meal, 2) soybean meal plus ruminally protected Lys and Met, 3) corn distillers grains, and 4) corn distillers grains plus ruminally protected Lys and Met. Dry matter intakes were lower for cows...

During the mid 1990s a potentially serious, chronic syndrome was reported in well-managed beef and dairy herds from unrelated parts of South Africa. Farmers reported that it manifested as various combinations of decreased production, decreased weaning masses, apparent immune breakdown in previously immunocompetent animals, increased reproductive disorders, various mineral imbalances in non-defi...

Molasses meal is a popular stock feed which is manufactured from two by-products of the sugar milling process, namely cane flour and molasses. Cane flour, or pulp, is prepared from bagasse by separating the pithy fraction and then drying and milling it. In this form it is capable of absorbing up to four times its own weight of molasses. One such stock feed, produced in Natal, is made up of 75% ...

Blocks containing urea were provided to groups of penned sheep fed ad libitum on roughage of either 2.3 % or 5.1 % crude protein content and the results were compared with unsupplemented groups. One block contained 7.1% urea with finely ground sorghum, distillers solubles, common salt and rock phosphate. The other block contained 30.070 urea with common salt, rock phosphate, molasses and pollar...

The application of ion-exclusion chromatography to desugarization of molasses has been investigated in the beet sugar industry for many years and is now being applied routinely to sucrose recovery. Recent work on the desugarization of molasses from cane processing has been carried out and a large-scale system is under construction. Ion-exclusion chromatographic processes are very efficient for ...

A survey has been carried out on the composition of final molasses from South African sugar factories. Regional and seasonal trends in various parameters have been noted, and the degree of exhaustion of the molasses has been commented upon. Included in the survey are data on the nonsucrose constituents of molasses, and the inorganic ash components. Comparisons are made with a similar survey con...
