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 …

Determining The Accuracy Of Gestation Feed Drops (2008), J D. Schneider, Michael D. Tokach, Steven S. Dritz, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Objective: To determine the accuracy of three different types of gestation feed drops. Materials and methods: Econo, Accu, and Ultra feed drops (Automated Production Systems, Assumption, Illinois) were attached to feed lines at three angles (90Ëš, 75Ëš, and 60Ëš). Feed was collected and weighed at settings of 2, 4, 6, 8, and 10 lb (0.9, 1.8, 2.7, 3.6, and 4.65 kg) for the Econo and Accu feed drops and 2, 4, 6, and 8 lb for the Ultra feed drops. Results: There was a drop type × angle × feed level interaction (P<.01) for the feed settings versus the actual amount dropped. At 90Ëš, the relationship between the feeder setting (x) and actual quantity of feed dropped was best described by the regression equation (1.156x + 0.244) for the Econo, (1.010x + 0.072) for the Accu, and (1.009x + 0.231) for the Ultra feed drops. At 75Ëš, the regression equations were (1.014x — 0.139) for the Econo, (0.997x + 0.057) for the Accu, and (1.005x + 0.156) for the Ultra feed drops. At 60Ëš, the regression equations were (0.689x — 0.076) for the Econo, (0.989x — 0.249) for the Accu, and (0.951x + 0.026) for the Ultra feed drops. Implications: The type of feed drop and its angle relative to the feed line influences the amount of feed dispensed at a feeder setting. The Accu and Ultra feed drops more accurately dispense the correct amount of feed than the Econo feed drops.; Journal of Swine Health and Production; 16; Swine Day, 2008, Kansas State University, Manhattan, KS, 2008

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

Kansas Agricultural Experiment Station Research Reports

Two experiments utilizing a total of 530 pigs were conducted to evaluate the effects of commercial enzymes in diets containing dried distillers grains with solubles (DDGS) on nursery pig growth performance. In Exp. 1, 180 pigs (initially 19.9 lb) were used in a 27-d growth trial to compare the effects of Easyzyme, Hemicell-W, and Porzyme in diets containing 30% DDGS on weanling pig performance. The 5 dietary treatments fed were a positive control (corn-soybean meal-based diet), negative control (diet with 30% corn DDGS), and the negative control diet with either 0.05% Easyzyme, 0.05% Hemicell-W, or 0.05% Porzyme added. Overall (d …

Kansas Agricultural Experiment Station Research Reports

Two experiments were performed to determine the effects of adding an enhanced feed flavor to the creep feed on the proportion of piglets consuming creep feed within litters and preweaning performance (Exp. 1) and the interactive effects of preweaning exposure to the flavor, nursery diet complexity, and flavor addition to nursery diets on postweaning performance (Exp. 2). In Exp. 1, 50 sows (PIC 1050) were blocked according to parity and date of farrowing and allotted to 2 experimental treatments in a randomized complete block design. Treatment 1 was a creep diet with no flavor (negative control), and treatment 2 was …

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
