Developing Accurate Spatial Maps Of Cotton Fiber Quality Parameters, Gretchen F. Sassenrath Apr 2008

Developing Accurate Spatial Maps Of Cotton Fiber Quality Parameters, Gretchen F. Sassenrath

Conference on Applied Statistics in Agriculture

Awareness of the importance of cotton fiber quality (Gossypium, L. sps.) has increased as advances in spinning technology require better quality cotton fiber. Recent advances in geospatial information sciences allow an improved ability to study the extent and causes of spatial variability in fiber parameters. However, these studies are often harvested by hand and ginned on small research gins. Fiber quality from cotton lint harvested and ginned in this manner is different from that machine-harvested and ginned on production-scale equipment. The objective of this study was to develop a method of correcting for error introduced into cotton fiber quality parameters …

Nonlinear Mixed Models To Evaluate Effects Of Environment Conditions, Hair Coat, And Anchor Length On Body Temperature During Afternoon Milking Of Holstein Cows In Hawaii, N Aitha, A. M. Parkhurst, C. N. Lee, P. E. Hillman

Conference on Applied Statistics in Agriculture

A hot thermal environment is one factor that causes loss of activity, productivity and even death in cows. One reason may be the effect of hair coat (black or white) on body temperature during different activities and environment conditions. In this study, we attempt to characterize the relationship between body temperature over time using activity, physiological and environmental effects with a nonlinear regression model. The fixed and mixed versions of models are examined. We also examine the effect of the measuring device, anchor length (long or short). Environmental effects, such as, air temperature, thermal heat index (THI), relative humidity, solar …

A Two-Stage Approach For Estimating The Effect Of Dna Methylation On Differential Expression Using Tiling Array Technology, Suk-Young Yoo, R. W. Doerge Apr 2008

A Two-Stage Approach For Estimating The Effect Of Dna Methylation On Differential Expression Using Tiling Array Technology, Suk-Young Yoo, R. W. Doerge

Conference on Applied Statistics in Agriculture

Epigenetics is the study of heritable alterations in gene function without changing the DNA sequence itself. It is known that epigenetic modifications such as DNA methylation and histone modifications are highly correlated with the regulation of gene expression. A twostage analysis is proposed that employs a hidden Markov model and a linear model to evaluate differential expression as related to DNA methylation for the purpose of examining the effects of DNA methylation on gene regulation using tiling array technology. In the first stage, a hidden Markov model (HMM) is employed to estimate the methylation status per tile by utilizing information …

Spatial Clustering Using The Likelihood Function, April Kerby, David Marx, Ashok Samal, Viacheslav Adamchuk Apr 2008

Spatial Clustering Using The Likelihood Function, April Kerby, David Marx, Ashok Samal, Viacheslav Adamchuk

Conference on Applied Statistics in Agriculture

Clustering has been widely used as a tool to group multivariate observations that have similar characteristics. However, most attempts at formulating a method to group similar multivariate observations while taking into account their spatial location are relatively ad hoc and do not account for the underlying spatial structure of the variables measured [12, 13, 14]. This paper proposes a method to spatially cluster similar observations based on the likelihood function. The geographic or spatial location of the observations can be incorporated into the likelihood of the multivariate normal distribution through the variance-covariance matrix. The variance-covariance matrix can be computed using …

Modeling Seasonal Wine Grape Development Using A Mixture Technique, William J. Price, Bahman Shafii, Paul E. Blom, Julie M. Tarara, Nick Dokoozlian, Luis J. Sanchez Apr 2008

Modeling Seasonal Wine Grape Development Using A Mixture Technique, William J. Price, Bahman Shafii, Paul E. Blom, Julie M. Tarara, Nick Dokoozlian, Luis J. Sanchez

Conference on Applied Statistics in Agriculture

Biological growth data typically display an increasing sigmoidal pattern over time. Grape development is no exception and shows a similar general trend. A detailed examination of the growth process in grapes, however, reveals a few systematic deviations from this pattern. Specifically, grape development is often characterized by localized areas of growth plateaus leading to an overall growth pattern referred to as a double sigmoidal curve. Capturing and characterizing these local changes in growth is important as they represent important phases in grape development such as veraison. This paper utilizes a model adapted from the technique of mixture models to estimate …

Comparisons Of Two Symmetric Density Function Solutions Of Aphid Population Growth Models, J. H. Matis, T. R. Kiffey, W. Van Der Werf, A. C. Costamagna, T. I. Matis, G. J. Michels Jr Apr 2008

Comparisons Of Two Symmetric Density Function Solutions Of Aphid Population Growth Models, J. H. Matis, T. R. Kiffey, W. Van Der Werf, A. C. Costamagna, T. I. Matis, G. J. Michels Jr

Conference on Applied Statistics in Agriculture

Aphids are among the world's most devastating crop pests, and their population trajectories in field crops are characterized by rapid boom and bust, under the influence of bottom up (host plant) and top down (natural enemy) forces. Theoretical development in aphid growth trajectory modeling has recently advanced quite significantly, and the logistic and normal probability density functions have been found to provide analytical solutions to mechanistic models of the aphid population growth dynamics. The logistic or hyperbolic secant squared model captures a growth trajectory shaped by negative feedback of the aphid population on itself, due to the accumulation of adverse …

Statistical Issues In The Normalizationof Multi-Species Microarray Data, John R. Stevens, Balasubramanian Ganesan, Prerak Desai, Sweta Rajan, Bart C. Weimer

Conference on Applied Statistics in Agriculture

Several species of bacteria are involved in the production of cheese, including Lactobacillus brevis and Lactococcus lactis. A custom-designed Affymetrix microarray was recently developed to study gene expression in three organisms on a single chip. This array contains only perfect match features for the coding and non-coding regions in the genomes of all three sequences. The multi-species nature of this array version raises interesting questions regarding the preprocessing or normalization strategies for the analysis of gene expression data. We present and evaluate several possible strategies using both cDNA dilution data and experimental expression data from a repeated measures design. The …

Multi-Trait Qtl Mapping Using A Structural Equation Model, Xiaojuan Mi, Kent M. Eskridge, Dong Wang Apr 2008

Multi-Trait Qtl Mapping Using A Structural Equation Model, Xiaojuan Mi, Kent M. Eskridge, Dong Wang

Conference on Applied Statistics in Agriculture

Research on mapping quantitative trait loci (QTL) often results in data on a number of traits that have well established causal relationships. Many multi-trait QTL mapping methods, taking into account the correlation among the multiple traits, have been developed to improve the statistical power of the test for QTL and the precision of parameter estimation. However none of these methods are capable of incorporating the causal structure among the traits with the consequence that genetic functions of the QTL may not be fully understood. Structural equation modeling (SEM) allows researchers to explicitly characterize the causal structure among the variables and …

Dynamic Clustering Of Cell-Cycle Microarray Data, Lingling An, R. W. Doerge Apr 2008

Dynamic Clustering Of Cell-Cycle Microarray Data, Lingling An, R. W. Doerge

Conference on Applied Statistics in Agriculture

The cell cycle is a crucial series of events that are repeated over time, allowing the cell to grow, duplicate, and split. Cell-cycle systems play an important role in cancer and other biological processes. Using gene expression data gained from microarray technology it is possible to group or cluster genes that are involved in the cell-cycle for the purpose of exploring their functional co-regulation. Typically, the goal of clustering methods as applied to gene expression data is to place genes with similar expression patterns or profiles into the same group or cluster for the purpose of inferring the function of …

Testing Variance Components By Two Jackknife Methods, Jixiang Wu, Johnie N. Jenkins, Jack C. Mccarty Apr 2008

Testing Variance Components By Two Jackknife Methods, Jixiang Wu, Johnie N. Jenkins, Jack C. Mccarty

Conference on Applied Statistics in Agriculture

The jackknife method, a resampling technique, has been widely used for statistical tests for years. The pseudo value based jackknife method (defined as pseudo jackknife method) is commonly used to reduce the bias for an estimate; however, sometimes it could result in large variation for an estimate and thus reduce the power for parameters of interest. In this study, a non-pseudo value based jackknife method (defined as non-pseudo jackknife method) was used for testing variance components under mixed linear models. We compared this non-pseudo value based jackknife method and the pseudo value based method by simulation regarding their biases, Type …

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

Blade Tenderization In Combination With Injection Enhancement Containing An Enzyme Increases Tenderness Of Strip Steaks From Fed Cull Cows, 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 …

Packaging Atmospheres Alter Beef Tenderness, Fresh Color Stability, And Internal Cooked Color, J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt

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 …

Packaging Atmospheres And Injection Enhancement Affect Beef Tenderness And Sensory Traits, J.P. Grobbel, Michael E. Dikeman, George A. Milliken, Melvin C. Hunt Jan 2008

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 …

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

Vitamin A Restriction During Finishing Benefits Beef Retail Color Display Life, 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 …

Restricted Feeding Improves Performance Of Growing Steers During Subsequent Grazing On Native Flint Hills Pasture, C.O. Anglin, M.P. Epp, R.D. Derstein, B.B. Barnhardt, Dale A. Blasi, K. C. Olson, Christopher D. Reinhardt Jan 2008

Restricted Feeding Improves Performance Of Growing Steers During Subsequent Grazing On Native Flint Hills Pasture, C.O. Anglin, M.P. Epp, R.D. Derstein, B.B. Barnhardt, Dale A. Blasi, K. C. Olson, Christopher D. Reinhardt

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.

Crude Glycerin In Steam-Flaked Corn-Based Diets For Beef Cattle, G.L. Parsons, M.K. Shelor, James S. Drouillard Jan 2008

Crude Glycerin In Steam-Flaked Corn-Based Diets For Beef Cattle, G.L. Parsons, M.K. Shelor, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Plant oils contain large amounts of triglycerides that will react to a catalyst, such as methanol. The transesterification reaction between the oil and alcohol will produce approximately 10% crude glycerin and 90% biodiesel. Crude glycerin is distilled for use in human products such as soaps, cosmetics, and moisturizers, but the usefulness of glycerin as a feed source for livestock is unclear. Rapid expansion of the biodiesel industry has created excess supplies of crude glycerin. It is thought that glycerin can be used in ruminant diets to decrease feed costs, but crude glycerin from biodiesel production can contain various levels of …

Dried Distiller’S Grains With Solubles In Steam-Flaked Or Dry-Rolled Corn Diets With Reduced Roughage Levels, M.L. May, M.L. Hands, M.J. Quinn, J.O. Wallace, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, Christopher D. Reinhardt, James S. Drouillard Jan 2008

Dried Distiller’S Grains With Solubles In Steam-Flaked Or Dry-Rolled Corn Diets With Reduced Roughage Levels, M.L. May, M.L. Hands, M.J. Quinn, J.O. Wallace, K.K. Karges, M.L. Gibson, Brandon E. Depenbusch, Christopher D. Reinhardt, James S. Drouillard

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 …

Dried Distiller’S Grains In Steam-Flaked Corn Finishing Diets With Decreased Roughage Levels, 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, 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
