Kansas Agricultural Experiment Station Research Reports
A total of 180 nursery pigs (PIC 327 × 1050, initially 25.2 lb BW) were used in a 21-d trial to evaluate the effects of increasing dietary wheat middlings on growth performance. Pens of pigs were balanced by initial BW and were randomly allotted to 1 of 5 dietary treatments with 6 replications per treatment. The 5 corn-soybean meal-based diets contained 0, 5, 10, 15 or 20% wheat middlings. Overall (d 0 to 21), pigs fed increasing wheat middlings had decreased ADG (linear, P<0 .05) and ADFI (linear, P<0 .005), but F/G was not affected by dietary wheat middlings. Despite the linear decrease in ADG and ADFI, the biggest reduction in performance was not observed until wheat middlings increased beyond 15% of the diet. This suggests that in some cases, the slight decrease in ADG with a low inclusion of wheat middlings (<15%) to the diet might be economically justified, so its inclusion needs to be evaluated on an income over feed costs basis.; Swine Day, Manhattan, KS, November 17, 2011

Kansas Agricultural Experiment Station Research Reports
Deoxynivalenol (DON), also known as vomitoxin, was prevalent in the 2009 U.S. corn crop and subsequently present in dried distillers grains with solubles (DDGS), in which DON levels are about 3 times higher than the original corn source. One method shown to reduce DON levels was by increasing moisture and temperature when sodium bisulfite was added to DON-contaminated corn (Young et al., 19874). Therefore, a pilot study aimed first to replicate these results by placing DON-contaminated DDGS in an autoclave (60 min at 250°F) in the presence of sodium metabisulfite (SMB). The study used 6 treatments: (1) control, (2) 0.5% …

Dietary Sulfur Concentration Has No Effect On In Vitro Fermentative Activity Of Ruminal Mixed Microorganisms, S. Uwituze, Larry C. Hollis, James S. Drouillard
Kansas Agricultural Experiment Station Research Reports
We previously reported that elevated concentrations of dietary sulfur (0.65% sulfur, dry basis) in finishing diets containing dried distillers grains with solubles decreased dry matter intake and average daily gains of feedlot cattle. Furthermore, high dietary sulfur concentrations yielded lower ruminal concentrations of volatile fatty acids, but were associated with increased ruminal ammonia concentrations and improved total tract digestibility of the diet. The objective of this study was to investigate, in culture tubes, effects of added sulfur on in vitro dry matter disappearance, volatile fatty acid profiles, and ammonia concentrations from substrates containing different sulfur concentrations when fermented by mixed …
