Kansas Agricultural Experiment Station Research Reports

A total of 1,160 barrows (PIC, initially 68.4 lb) were used in a 97-d study to determine the influence of glycerol and dried distillers grains with solubles (DDGS) on growing-finishing pig performance, carcass characteristics, and fat quality. Pigs were blocked by weight and randomly allotted to 1 of 6 dietary treatments with 7 replications per treatment. Pigs were fed corn-soybean meal-based diets arranged in a 2 × 3 factorial with main effects of glycerol (0, 2.5, or 5%) and DDGS (0 or 20%). Overall (d 0 to 97), there were no glycerol × DDGS interactions (P>0.12) for growth performance, …

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 …

Resynchronized Pregnancyrates In Dairy Cattle: Timingof Gonadotropin-Releasinghormone Injection Before Timedartificial Insemination (2008), C.A. Martel, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Lactating dairy cows and replacement virgin heifers of unknown pregnancy status were treated with either gonadotropin-releasing hormone (GnRH) or saline to initiate a resynchronization program that was continued 7 days later when a not-pregnant diagnosis was determined. Nonpregnant cattle were administered prostaglandin F2αand then either injected with GnRH 56 hours later and artificially inseminated (AI) by appointment at 72 hours or injected and inseminated concurrently at 72 hours. Injection of GnRH at 56 hours produced more pregnancies than injection of GnRH at 72 hours when AI was administered at 72 hours in both treatments (30.9 vs. 15.2%). Further, starting the …

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

Kansas Agricultural Experiment Station Research Reports

Several meat quality traits affect consumers' overall purchase decisions and satisfaction with meat products, but color is the major factor affecting purchasing decisions. According to some researchers, tenderness is the most important palatability attribute in consumers' overall eating experience. Case-ready packaging in the meat industry is growing at a rapid rate and generally includes modified atmosphere packaging (MAP) with specific gases. Advantages of MAP include use of a centralized location, improved sanitation control, more consistent products, and increased marketing flexibility. Packaging beef in highoxygen (HiO2) MAP results in a desirable bright red lean color but can have detrimental effects on …

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 …

Kansas Agricultural Experiment Station Research Reports

Distiller's grains have been used extensively in the U.S. Corn Belt, where producers commonly feed dry-rolled or highmoisture corn. Fuel ethanol production is expanding into the High Plains, where most feedlots flake grain. Compared with dry- rolled corn, steam-flaked corn usually increases or has no change in average daily gain, yields lower dry matter intake and results in 12 to 16% improvement in efficiency. Previous research at Kansas State University and elsewhere suggests that the value of distiller's grains is different in flaked grain diets than in dry-rolled diets. We think this might be due to lower rumen pH when …

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 …

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 …

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 …

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 …

Nutrient Balance Of A Commercial Feedlot (2008), S.Q. Jones, J.M. Ham, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

The ability to develop nutrient balance for a livestock operation is important for maintaining a long-term sustainable production system and for compliance with current and future environmental regulations. Producers invest considerable financial resources in farm inputs, primarily feed and livestock. When animals leave the farm, they retain a portion of the feed nutrients they consumed, but the majority of consumed nutrients are excreted. Once excreted, certain compounds in the manure volatilize, which lowers the manure nutrient content and diminishes economic value of the manure as fertilizer. In addition, these volatile compounds can create air quality concerns. Operations designated as concentrated …

Kansas Agricultural Experiment Station Research Reports

Poor grazing distribution is a major problem on rangelands of the western United States. Grazing animals tend to congregate in areas near water, shade, and level terrain. These areas typically become overgrazed, while less preferred areas of pasture remain undergrazed. Solutions to localized overgrazing include cross-fencing and water development; however, most land managers are unwilling to bear the expense associated with these strategies. Most types of supplements, including mineral supplements, have potential to lure cattle into under-utilized areas of range and pasture. Cows spend up to 40% of their time within 650 yards of self-fed supplements, but relationships between terrain …

Bovine respiratory disease (BRD) is the most economically devastating feedlot disease. Risk factors associated with incidence of BRD include: 1) stress associated with maternal separation; 2) stress associated with introduction to an unfamiliar environment; 3) low feed intake associated with the introduction of novel feedstuffs into the diet; 4) exposure to novel pathogens upon transport to a feeding facility and commingling with unfamiliar cattle; and 5) inappropriately administered respiratory disease vaccination programs. Management practices collectively referred to as preconditioning are thought to minimize carcass damage resulting from BRD. Preconditioning management attempts to eliminate or reduce risk factors for respiratory disease …

Distiller’S Grain Market Price Relationships, Discovery, And Risk Management (2008), T.W. Van Winkle, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

The substantial increase in corn use by the ethanol refinery industry (Figure 1) has resulted in livestock producers, especially cattle feeders, substituting distiller's grain (DG) for corn in feed rations. DG futures markets do not exist, but actively traded corn and soybean meal (SBM) futures are the most probable markets for hedging DG price risk. Therefore, the ability to offset DG price risk using corn and SBM futures is incorporated into analysis to quantify the strength of price relationships. If DG prices and corn or SBM futures prices are strongly related, then a viable cross hedging opportunity might exist. If …

Kansas Agricultural Experiment Station Research Reports

Rapid expansion of fuel ethanol production in the High Plains, where feedlots commonly use steam-flaked corn diets, has popularized substituting dried distiller's grains with solubles (DDGS) for a portion of the steam- flaked corn. Most of the starch in corn is removed during ethanol production. The residual material is rich in fiber, ruminal undegradable protein, and fat. Adding roughage to high-concentrate finishing diets helps maintain ruminal function by stimulating salivation, rumination, and gut motility. The source and level of roughage can influence dry matter intake. Our objective was to examine ruminal fermentation characteristics and diet digestibility when steam-flaked corn-based finishing …

Kansas Agricultural Experiment Station Research Reports

Dried distiller's grains with solubles (DDGS) are the main byproduct of dry milling, the process used most frequently for fuel ethanol production. DDGS consist of the spent grains following ethanol distillation and are high in protein, fat, fiber, and minerals. Alfalfa hay and corn silage are roughages most commonly included in feedlot diets and are one of the most expensive ingredients in feedlot diets on an energy basis. Comparing use of alfalfa hay and corn silage in conjunction with DDGS can provide useful information on how to obtain maximum benefit from these ingredients. Our objective was to evaluate the use …

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.

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 …

Kansas Agricultural Experiment Station Research Reports

A novel diet formulation strategy incorporating wet corn gluten feed at 47% of diet dry matter was evaluated in late-lactation cows. Diets were formulated for similar protein and energy concentrations with dramatic differences in forage sources. Milk fat and protein concentrations increased with the high wet corn gluten feed inclusion rate, and this diet tended to increase milk fat yield. The preliminary work indicates that very low cost rations incorporating wet corn gluten feed may be formulated to maintain milk production, at least in late-lactation cows.; Dairy Day, 2008, Kansas State University, Manhattan, KS, 2008; Dairy Research, 2008 is known …
