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 Jan 2008

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

Summary 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

Dietary Molasses Enhancesruminal Biohydrogenationand Partially Alleviates Diet-Induced Milk Fat Depression (2008), Barry J. Bradford, Evan C. Titgemeyer Jan 2008

Dietary Molasses Enhancesruminal Biohydrogenationand Partially Alleviates Diet-Induced Milk Fat Depression (2008), Barry J. Bradford, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Milk fat depression remains a problem on dairy farms, and in recent years, incorporation of distillers grains (typically with solubles added and often dried) has contributed to this problem on some farms. In this study, we evaluated whether molasses could prevent milk fat depression in cows fed a high-risk diet. Replacing up to 5% of dietary corn with cane molasses linearly increased the yield of short- and medium-chain fatty acids in milk, indicating a positive effect on de novo fatty acid synthesis in a milk fat depression environment. Molasses, however, tended to linearly decrease milk yield and linearly decreased milk …

Estimating Optimal Operationtime Of Korral Kools On Dairycows In A Desert Environment (2008), X.A. Ortiz, John F. Smith, Barry J. Bradford, Joseph P. Harner

Kansas Agricultural Experiment Station Research Reports

Developing management strategies for Korral Kools will help producers provide cooling in the housing area while minimizing the operational cost of the Korral Kools system. Two experiments were conducted at a dairy in Saudi Arabia to evaluate operational time of Korral Kools for multiparous and primiparous dairy cows. For multiparous cows, running time per day of Korral Kools should be continuous, but for primiparous cows, no difference in performance was detected between 21 and 24 hours. However, producers need to be careful when reducing daily operation time of Korral Kools for primiparous cows because elevated core body temperatures were observed …

Opportunities With Low Profilecross Ventilated Freestallfacilities (2008), John F. Smith, Joseph P. Harner, Barry J. Bradford, M.W. Overton

Kansas Agricultural Experiment Station Research Reports

Low profile cross ventilated freestall buildings are one option for dairy cattle housing. These facilities allow producers to control the cows' environment during all seasons of the year. As a result, an environment similar to the thermoneutral zone of a dairy cow is maintained during both summer and winter, resulting in more stable core body temperatures. Low profile cross ventilated facilities allow buildings to be placed closer to the parlor, thus reducing the time cows are away from feed and water. Other advantages include a smaller overall site footprint than naturally ventilated facilities and less critical orientation because naturally ventilated …

Blade Tenderization In Combination With Injection Enhancement Containing An Enzyme Increases Tenderness Of Strip Steaks From Fed Cull Cows (2008), Stacy L. Hutchinson, M.J. Daniel, James J. Higgins, John A. Unruh, Melvin C. Hunt

Kansas Agricultural Experiment Station Research Reports

Cow meat is tougher than meat from young steers and heifers and typically has a less desirable, darker color. It is generally assumed that cow meat will need to be ground or have some form of post-mortem tenderization applied to be merchandized as a whole muscle product. Most cow steaks are fabricated by food service providers for their customers with different specifications for aging and post-mortem tenderization application. Aging, blade tenderization, and injection enhancement are commonly used on cow meat to increase tenderness. It is unknown if an extended aging period is needed in addition to a combination of tenderization …

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.

Restricting Vitamin A In Cattle Diets Improves Beef Carcass Marbling And Usda Quality And Yield Grades (2008), A.M. Arnett, M.J. Daniel, Michael E. Dikeman Jan 2008

Restricting Vitamin A In Cattle Diets Improves Beef Carcass Marbling And Usda Quality And Yield Grades (2008), A.M. Arnett, M.J. Daniel, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Marbling continues to be a major factor affecting profitability for beef producers, processors, retailers, and restaurateurs. However, feeding animals to "˜fatten' is quite inefficient, requiring about 2.25 times more energy than is needed for producing lean muscle. For the cattle feeding industry to be sustainable in the future, increases in marbling must be accomplished without increasing days on feed, slaughter age carcass weight, and fatness and without sacrificing feed efficiency and carcass cutability. A 2002 survey of feedlot nutritionists revealed that most recommended supplementation of vitamin A to feedlot cattle at levels exceeding the guidelines of the National Research Council …

Vitamin A Restriction During Finishing Benefits Beef Retail Color Display Life (2008), M.J. Daniel, A.M. Arnett, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Because the beef industry commonly uses marbling as an indicator of meat palatability, determining the most cost effective methods of increasing quality grade in cattle is a high priority. Previous research showed that weaning calves at around 90 instead of 200 days of age can be beneficial in reducing cow production costs and increasing marbling in feedlot steers. Other studies demonstrated that high levels of vitamin A inhibit development of intramuscular fat. Vitamin A restriction is used commonly in Japanese cattle to increase marbling scores; this stimulated interest in applying this restriction in U.S. beef production systems. However, little research …

Kansas Agricultural Experiment Station Research Reports

Fat supplementation before calving (i.e., prepartum) can alter reproductive performance of beef cows. These effects do not seem to be related to energy or protein content of the supplement. Chemical structures of some plant fats are similar to chemical structures of certain reproductive hormones; moreover, some fats are precursors to prostaglandin production. Prepartum vegetable fat supplementation has been associated with improved reproductive performance by cows and heifers managed for artificial insemination (AI) breeding. The biological basis for this effect is not clearly understood but is believed to reflect the influence of fat supplements on cyclicity, body weight, body condition, and …
