Optimizing Ground Beef Lean Sources To Maximize Display Color Life (2008), C. Raines, Melvin C. Hunt, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

It is widely accepted that meat color is the most important influencer of consumers' meat purchasing decisions. Understanding how ground cow meat discolors is, and will continue to be, very important as a large influx of cull dairy cows in the U.S. meat supply is predicted. Optimal management and more timely marketing of cows should result in increased revenue for the beef industry. However, many valuable by-products from cows have been labeled as specified risk materials accompanied by a lost value. Thus, there is an unprecedented need to add value to cow meat. Research characterizing cow muscles and how to …

Kansas Agricultural Experiment Station Research Reports

Beef stocker operators are margin-operators, and rising feed costs force them to consider alternative feeding strategies to reduce production costs. Limit-feeding is a management technique that has positive implications for cost control. In this experiment, we restricted dry matter intake to determine if steers could compensate for a period of dietary restriction during intensive early grazing. This study illustrated that limit-feeding could reduce feed costs for stocker and background operators.

Digestibility Of Dried Distiller’S Grains With Solubles In Steam-Flaked Or Dry-Rolled Corn Diets (2008), M.L. May, M.J. Hands, M.J. Quinn, J.O. Wallace, Leigh W. Murray, Christopher D. Reinhardt, James S. Drouillard Jan 2008

Digestibility Of Dried Distiller’S Grains With Solubles In Steam-Flaked Or Dry-Rolled Corn Diets (2008), M.L. May, M.J. Hands, M.J. Quinn, J.O. Wallace, Leigh W. Murray, Christopher D. Reinhardt, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

In previous experiments, we observed that the nutritional value of dried distiller's grains is less when added to finishing diets made of steam-flaked corn than when added to diets of dry-rolled corn. We hypothesized that effects of grain processing on value of distiller's grains are attributable to differences in the digestion characteristics of grains processed via flaking or dry rolling. In this study, our objective was to evaluate differences in ruminal metabolism and total tract digestion of diets made from dry-rolled or steam-flaked corn with and without dried distiller's grains.

Effects Of Expander Conditioning On The Nutritional Value Of Diets With Dried Distillers Grains With Solubles In Nursery And Finishing Pigs (2008), C Feoli, Terry L. Gugle, S D. Carter, Joe D. Hancock, Keith C. Behnke Jan 2008

Effects Of Expander Conditioning On The Nutritional Value Of Diets With Dried Distillers Grains With Solubles In Nursery And Finishing Pigs (2008), C Feoli, Terry L. Gugle, S D. Carter, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to determine the effects of expander conditioning on nutritional value of diets without and with corn- and sorghum-based dried distillers grains with solubles (DDGS). In Exp. 1, 180 nursery pigs (average weight 29 lb) were assigned to 30 pens. Treatments were arranged as a 3 × 2 factorial with main effects of diet formulation (corn-soybean meal vs. 30% corn- or sorghum-based DDGS) and conditioning (standard steam vs. expander) prior to pelleting. Pigs fed corn-soybean meal diets had better (P<0.005) ADG, F/G, and digestibility of DM, N, and GE than pigs fed diets with DDGS. Diets with corn-based DDGS supported better (P<0.03) ADG, F/G, and digestibility of DM and N than diets with sorghum-based DDGS. Expander processing improved (P<0.009) ADG, F/G, and digestibility of DM, N, and GE compared with standard conditioning. Pigs fed diets with sorghum-based DDGS showed the greatest response in F/G to expander conditioning leading to a DDGS source × conditioning interaction (P<0.008). In Exp. 2, 176 finishing pigs (average weight 164 lb) were assigned to 16 pens. Treatments were arranged as a 2 × 2 factorial with main effects of diet formulation (corn-soybean meal vs. 40% sorghum-based DDGS) and conditioning (standard steam vs. ex-pander) prior to pelleting. Net electrical energy required for feed processing was lower (P<0.001) and production rate was greater (P<0.005) for the corn-soybean meal diets than for diets with DDGS. However, pellet durability was improved (P<0.001) by addition of DDGS to the diets. Pigs fed corn-soybean meal diets had better (P<0.03) overall ADG and F/G than pigs fed diets with DDGS. Expander conditioning did not affect ADG (P>0.83) but improved overall F/G and dressing percentage (P<0.007). In Exp. 3, 192 finishing pigs (average weight 222 lb) were assigned to 16 pens to determine nutrient digestibility. Treatments were the same as in Exp. 2. Feed and water was consumed ad libitum during a 6-d adjustment period; then, feces were collected for 2 d. Corn-soybean meal diets had greater (P<0.001) digestibility of DM, N, and GE than diets with DDGS, and expander conditioning improved (P<0.02) digestibility of DM, N, and GE compared with standard conditioning. However, the improved digestibility of DM with expander conditioning was apparent primarily for the DDGS diets (diet × conditioning interaction, P<0.01). In conclusion, expanding diets improved ADG, F/G, and nutrient digestibility in nursery pigs and F/G, dressing percentage, and nutrient digestibility in finishing pigs fed diets without and with DDGS.; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008

Determining Optimum Flake Density For Feedlot Heifers (2008), M.L. May, M.J. Quinn, Brandon E. Depenbusch, James S. Drouillard Jan 2008

Determining Optimum Flake Density For Feedlot Heifers (2008), M.L. May, M.J. Quinn, Brandon E. Depenbusch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Escalating costs of natural gas and electrical utilities have greatly increased the cost of flaking grain for feedlots. Energy demand for flaking is inversely related to bulk density of flaked grain; the lighter, more highly processed flakes typically require longer steaming times and greater roll pressures, which ultimately decreases mill. Corn is most commonly flaked to a density of about 28 lb/bushel, and published research results indicate that levels less than 28 lb/bushel afford no further advantage with respect to animal performance. Little information is available concerning the relative feed value of grains flaked to heavier bulk densities. Flaking grains …

Packaging Atmospheres And Injection Enhancement Affect Beef Tenderness And Sensory Traits, J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Case-ready meat provides many benefits, including quality and safety. Meat packaged in high-oxygen (HiO2) modified atmosphere packaging (MAP) has a desirable bright red display color but may have increased off- flavors and decreased tenderness. According to several international research reports, steaks aged and packaged in HiO2 MAP had more off-flavor, including warmed-over flavor, and were less tender and juicy than steaks aged in vacuum packaging (VP). Research at Kansas State University found that injection-enhanced beef quadriceps muscles packaged in HiO2 MAP were less tender and had more offflavors than those in ultra-low oxygen MAP. Detrimental effects of O2 on tenderness …

Heifers Sired By Bulls With Low Residual Feed Intake Estimated Breeding Values Have Lower Residual Feed Intake Than Heifers Sired By Bulls With High Residual Feed Intake Estimated Breeding Values (2008), J. Minick Bormann, Daniel W. Moser, T.T. Marston

Kansas Agricultural Experiment Station Research Reports

Feed is one of the largest costs in a cow/calf or feedlot operation. However, very little data is available to aid producers in genetically improving their herd for feed efficiency. In Australia, bull tests record individual feed intakes, which are used to calculate Estimated Breeding Values (EBV) (analogous to EPD) for residual feed intake (RFI). Residual feed intake measures the degree to which feed intake deviates from expected levels based on the animal size and rate of gain. Negative values are good; they indicate the animal ate less than expected for its size and growth rate. Our objective was to …

Dried Distiller’S Grains In Steam-Flaked Corn Finishing Diets With Decreased Roughage Levels (2008), M.L. May, M.J. Quinn, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, James S. Drouillard Jan 2008

Dried Distiller’S Grains In Steam-Flaked Corn Finishing Diets With Decreased Roughage Levels (2008), M.L. May, M.J. Quinn, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Distiller's grains are the primary coproduct derived from fuel ethanol production. As the fuel ethanol industry expands into the High Plains, distiller's grains are becoming increasingly available as an alternative feed for livestock. Optimizing the use of distiller's grains in flaked grain rations is important to maintaining a competitive advantage among feedlot producers in this region. Because distiller's grains are relatively high in fiber, it is conceivable that the level of roughages in feedlot diets could be reduced when distiller's grains are fed to cattle. Roughages normally have low energy density; therefore, the cost per unit of energy from roughages …

Influence Of Glycerol And Added Fat On Finishing Pig Performance (2008), A W. Duttlinger, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz Jan 2008

Influence Of Glycerol And Added Fat On Finishing Pig Performance (2008), A W. Duttlinger, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A 28-d study was conducted to determine the influence of dietary glycerol on grow-finish pig performance. The experiment was conducted at a commercial swine research facility in southwest Minnesota. A total of 1,093 pigs (initially 171.3 lb, PIC) were blocked by weight and randomly allotted to 1 of 6 dietary treatments. Pigs were fed corn-soybean meal-based diets. The treatments were arranged in a 2 × 3 factorial with main effects of glycerol (0, 2.5, or 5%) and added fat (0 or 6%). Overall (d 0 to 28), there was a fat × glycerol interaction (P<0.04) for ADFI. When 5% glycerol was added to diets without added fat, ADFI decreased; however, ADFI did not change when glycerol was added to diets containing 6% added fat. Pigs fed diets with added fat had improved (P<0.01) ADG and F/G compared with pigs fed diets with no added fat. Increasing glycerol decreased ADG (linear, P<0.02) and ADFI (linear, P<0.04) and tended (linear, P<0.08) to worsen F/G, a result of the negative effect of adding glycerol to diets without fat. In conclusion, 6% added fat improved ADG and F/G, but the glycerol used in this study decreased ADG and ADFI when added to diets without added fat.; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008

Kansas Agricultural Experiment Station Research Reports

A total of 48 gilts (initially 211 lb) were used to evaluate the effects of ractopamine HCl and α-lipoic acid on finishing pig performance and carcass characteristics. Pigs were blocked by weight and randomly allotted to 1 of 4 dietary treatments in a 22-d experi-ment. Pigs were fed corn-soybean meal-based diets. Treatments were arranged as a 2 × 2 factorial with main effects of ractopamine HCl (0 or 9 g/ton) and α-lipoic acid (0 or 300 ppm). For overall growth performance (d 0 to 22), ADG tended (P<0.09) to be greater for pigs fed ractopamine HCl. Although F/G improved (P<0.01) for pigs fed ractopamine HCl, there was a trend (P<0.07) for an interaction between ractopamine HCl and α-lipoic acid. For pigs fed diets without ractopamine HCl, added α-lipoic acid numerically improved F/G, whereas in pigs fed ractopamine HCl, added α-lipoic acid numerically worsened F/G. Average final weight tended (P<0.06) to be greater for pigs fed ractopamine HCl. No other differences in growth performance were observed. For the comparison of carcass characteristics, average live weight, HCW, yield, loin eye area at the 10th rib, and standardized fat-free lean were increased (P<0.04) for pigs fed ractopamine HCl. Average backfat thickness tended (P<0.06) to decrease for pigs fed ractopamine HCl. Tenth-rib backfat increased (P<0.05) for pigs fed α-lipoic acid, and the percent fat-free lean of pigs fed α-lipoic acid tended (P<0.10) to decrease as a result. In conclusion, the growth performance and carcass characteristics of pigs fed ractopamine HCl were improved. Feeding 300 ppm of α-lipoic acid did not affect growth performance but did tend to increase carcass fat content.; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008
