“…While not as obvious as S-PEM, S toxicosis as reflected by decreased DMI and ADG is economically detrimental. The effects of increased ethanol coproduct inclusion in feedlot diets on cattle performance has been well reviewed by Klopfenstein et al (2008) and more recently by Galyean et al (2012). determined energy content of DGS (dry, modified, and wet) based on cattle ADG or G:F, and reported net energy content was from 13 to 40 percent greater than that of corn, likely due to the greater fat content of DGS.…”

“…Despite a linear increase in S as DGS inclusion increases, a quadratic effect on ADG is often observed. In comparison to a corn-based finishing diet, ADG increases up to approximately 30% inclusion of wet DGS, and begins to decrease thereafter (Klopfenstein et al, 2008).…”

“…Future research should attempt to profile the SRB and other microbial populations throughout the early finishing period to determine if species shifts or population increases may explain the apparent lag time for peak H 2 S concentrations in cattle fed moderate to high S diets. Klopfenstein et al (2008) and Gaylean et al (2012) have thoroughly reviewed the literature related to potential interactions among grain processing and DGS inclusion rate in feedlot cattle diets on cattle performance, finding minimal interactions when dietary fat was accounted for. However, few studies have focused on the interaction between dietary S concentration and grain processing method.…”

“…Klopfenstein et al (2008) provided a thorough review of the literature related to the effects of distillers grains (DGS) inclusion rate in cattle diets, irrespective of S content, on performance and carcass characteristics. However, S content is one of the major factors limiting inclusion of ethanol co-products in feedlot cattle diets.…”

ABSTRACT:While many cattle feeding areas in the United States have long dealt with high sulfate water, increased feeding of ethanol co-products such as distillers grains with solubles to beef cattle has led to a corresponding increase in dietary sulfur. As a result, sulfur metabolism in the ruminant has been the focus of many research studies over the past ten years, and advances in our knowledge have been made. Excessive sulfur in cattle diets may have implications on trace mineral absorption, dry matter intake, and overall cattle growth. This review will focus on what we have learned about the metabolism of sulfur in the ruminant, including ruminal sulfate reducing bacteria, the role of ruminally available sulfur, factors affecting the production of hydrogen sulfide in the rumen, and the potential mechanisms behind sulfur toxicity in cattle.Additionally, this review will discuss potential strategies to minimize risk of sulfur toxicity when cattle are fed high-sulfur diets, including dietary and management strategies. Further research related to high-sulfur diets including implications for carcass characteristics, meat quality, and animal health will also be discussed. As ethanol production processes continue to change, the nutrient profile of the resulting co-products will as well. Often removal of one nutrient such as oil will result in the concentration of other nutrients such as sulfur. Thus it seems even more likely that a better understanding of sulfur metabolism in the ruminant will be important to beef cattle feeding in the future.

“…When compared with corn, distillers grains are not only less expensive, but also contain up to three times the levels of protein, fibre, and fat (Klopfenstein et al 2008). Hence, distillers grains are used widely in feedlot diets at levels varying from 10% to 80% on a DM basis.…”

Feeding wet distillers grains plus solubles contributes to sarcoplasmic reticulum membrane instability

et al. 2018

Abstract. Feeding wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. It was hypothesised that WDGS in feedlot diets increases PUFA concentration in the sarcoplasmic reticulum (SR) membrane, thereby altering membrane integrity, resulting in more rapid intracellular calcium leakage and improved tenderness. The objective of this study was to evaluate this hypothesis. Ninety-six crossbred steers were fed either a corn-based diet with 0% WDGS or 50% WDGS. Fifteen strip loins per treatment were collected, fabricated into steaks, aged and placed under retail display conditions. Steaks were used to measure tenderness, proteolysis, free calcium concentrations, lipid oxidation, sarcomere length and SR membrane fatty acid, phospholipid lipid, neutral lipid and total lipid profiles. Compared with steaks from steers fed 0% WDGS, steaks from steers fed 50% WDGS were more tender (P < 0.05) and had greater (P < 0.05) free calcium concentrations early post-mortem. Feeding 50% WDGS also tended to increase (P < 0.10) total PUFA concentrations, decrease (P < 0.10) total phospholipid concentration and increase (P < 0.10) total neutral lipid concentration for SR membrane. Steaks from steers fed 0% WDGS had greater (P < 0.05) lipid oxidation (TBARS values) than steaks from steers fed 50% WDGS after extended aging. Although differences in tenderness between the two treatments were detected, there were no corresponding differences (P > 0.10) in sarcomere length or proteolysis. This study showed that feeding WDGS may increase tenderness, possibly by increasing free calcium in muscle early post-mortem. However, the true mechanism that contributes to these differences is still unclear.

Various hydrolyzing enzymes are used in drygrind corn ethanol processes, mainly during liquefaction and saccharification steps, to improve yields of ethanol and/or distillers' corn oil. However, the effects of enzyme addition on characteristics of distillers' dried grains with solubles (DDGS) are not thoroughly understood. In this study, the effects of using acid-stable protease, pectinase, and cellulase enzymes during fermentation on chemical and physical characteristics of DDGS were evaluated, including in vitro digestibility using a pig digestion model. The use of a protease resulted in DDGS with a greater fiber content than the control (36% vs. 22%), as well as reduced protein digestibility (64% vs. 69%). The use of pectinase and cellulase (PC) also increased the fiber content of DDGS (29%) and significantly improved the protein content (27%) and protein digestibility (73%) compared with the other treatments. DDGS treated with hydrolyzing enzymes tended to have a darker color and lower waterholding capacity, but better amino-acid digestibility. Treatments with hydrolyzing enzymes significantly altered the composition and characteristics of DDGS, which strongly indicated that PC mix utilized is an effective combination to add during fermentation to produce high-quality DDGS without undesirable effects on ethanol production. The enzyme-treated DDGS can be an inexpensive and nutrientrich diet supply to the porcine diets; however, effects on cattle and dairy cow diets were beyond the scope of the study.
