A TOTAL of 28 crossbred wethers were used in two experiments to determine the digestibilty of hydrogenated tallow-, saturated fatty acidsand soybean oil-supplemented diets. Digestibility values for individual fats were determined by subtracting from total dietary lipid and fecal output the dietary and fecal lipids measured with basal diets. In the first experiment addition of 3% flaked, hydroge...

This experiment was conducted to determine whether increasing the net energy (NEL ) of a total mixed ration (TMR) with mainly unsaturated fat from corn distillers dried grains with solubles (DDGS) vs. rumen inert (RI)-saturated fat has similar impacts on animal performance. The experiment was an incomplete Youden square with three treatments and four 28-days periods, completed on a large commer...

Distillers grains (DG), a co-product of ethanol production used as protein and energy supplements in cattle diets, have been shown to increase fecal shedding of Escherichia coli O157:H7, a major foodborne pathogen. The reason for the positive association is not known. Because DG often replaces grain in the diet, decreased starch content and flow to the hindgut may create a favorable environment...

The influence of dietary fatty acid composition on intestinal active and passive transport function, brush border membrane composition, and morphology was examined in rats. Animals fed a semisynthetic diet high in saturated fatty acids demonstrated enhanced in vitro jejunal uptake of decanoic, dodecanoic, palmitic, stearic, and linoleic acid, as well as cholesterol and chenodeoxycholic and taur...

introduction corn has been recently used for producing ethanol fuel in the major corn-producing countries such as the us and brazil. recent diversion of corn for biofuel production along with the increased world's demand for this feedstuff has resulted in unprecedented rise in feed cost for poultry worldwide. alternative grains such as wheat and barley can be successfully replaced for corn in p...
