Physiological And Behavioural Evaluation Of Common Anaesthesia Practices In The Rainbow Trout, Kieran C. Pounder, Jennifer L. Mitchell, Jack S. Thomson, Tom G. Pottinger, Lynne U. Sneddon
Anesthesia and Analgesia Collection
Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a widely-used model species with relevance to both aquaculture and natural ecosystems. This study sought to establish the relative acute impact of commonly used anaesthetics on rainbow trout when used for anaesthesia or euthanasia by exploring their effects on aversion behaviour and stress physiology. Five widely used anaesthetics were investigated at two concentrations reflective of common laboratory practises: MS-222, benzocaine, 2-phenoxyethanol, …

Light weight stocker calves often experience health problems shortly after arrival to feeding facilities. Preventative health programs are routinely administered to calves upon arrival to reduce the incidence of Bovine Respiratory Disease. The major route of vaccine administration in cattle is via injection through either intramuscular or subcutaneous routes. Several products have been introduced that utilize the intranasal route of vaccine administration. There are several reasons why intranasal vaccine administration may be more beneficial: 1) Intranasal vaccine administration alleviates concerns that injections pose for Beef Quality Assurance programs. 2) Intranasal vaccine administration may be less stressful on the animal. 3) …

Intermittent Feeding Of Tylan Reduces Use Of In-Feed Antibiotics While Still Controlling Incidence Of Liver Abscesses In Finishing Steers, H. C. Muller, R. G. Amachawadi, H. M. Scott, J. S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Liver abscesses are a cause of concern for many feedlots across the country as they lead to a decrease in feedlot performance of finishing cattle as well as a decrease in the final carcass value. Loss in carcass value is due to not only the abscessed liver being condemned, but also due to trim loss associated with the condemned liver. The macrolide drug tylosin phosphate is the drug of choice for metaphylactic treatment of liver abscesses in feedlot cattle. The Food and Drug Administration approved the drug for over-the-counter use, however, from January 2017 all medically important (used in human …

Kansas Agricultural Experiment Station Research Reports
Ambulatory electrocardiogram monitoring, in the form of Holter monitoring, has been used in human and veterinary medicine for decades as an aid in the diagnosis and determination of appropriate therapy of heart rhythm disturbances. Within veterinary medicine, Holter monitors have been primarily used in companion animal species, yet little attention has been given to food animal species. Moreover, the heart rhythm in clinically normal cattle fed high concentrate diets and housed outdoors in confined drylot facilities has not been previously reported. In order to properly identify pathologic arrhythmias in cattle, the normal rhythm and arrhythmia prevalence in healthy cattle should …

Evaluation Of Trace Mineral Sources On Newly Arrived Stocker Cattle, C. S. Weibert, W. R. Hollenbeck, S. B. Laudert, J. D. Kubick, Dale Blasi
Kansas Agricultural Experiment Station Research Reports
Light weight stocker calves experience variable degrees of physiological and psychological stressors as they are assembled from various marketing points and transported to their destination. Susceptibility to disease in young, long hauled calves is greatly enhanced and the consequence of sickness is a major cause for poor production outcomes. Enhanced nutritional trace mineral programs that contain zinc, copper, and manganese from organic or hydroxy sources may be more efficacious as a means of minimizing disease or realizing improved performance than the sulfate form of these respective trace minerals.

Supplemental Zinc Sulfate Interacts With Optaflexx In Feedlot Heifers, C. L. Van Bibber-Krueger, R. G. Amachawadi, H. M. Scott, J. M. Gonzalez, J. S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Optaflexx is a beta-adrenergic agonist, and is fed to cattle during the final 28 to 42 days on feed to improve growth rate and feed efficiency. Beta-adrenergic agonists are repartitioning agents that stimulate muscle deposition at the expense of fat deposition. Zinc is a trace mineral element that functions as an important component of many enzyme systems, including those associated with nucleic acid synthesis and metabolism of proteins and carbohydrates, thus making it an essential nutrient for growth. The purpose of this study was to evaluate growth, carcass characteristics, and plasma urea nitrogen concentrations in finishing heifers supplemented with Optaflexx …

Flake Density, Roll Diameter, And Flake Moisture All Influence Starch Availability Of Steam-Flaked Corn, E. F. Schwandt, M. E. Hubbert, D. U. Thomson, Christopher Vahl, S. J. Bartle, C. D. Reinhardt
Kansas Agricultural Experiment Station Research Reports
Steam-flaked corn is commonly fed in feedlot finishing diets because steam-flaking improves starch availability and nutrient utilization, thus improving the overall feeding value of corn. In most operations which utilize steam-flaked corn, grain is processed to a pre-determined flake density by setting the rolls to a specific separation distance and using tension to hold rolls together. Flaked grain is most often produced to a bulk density between 24 and 32 lb/bu, with a common recommendation of 27 lb/bu for corn; however, flake density among steam-flakers within a single mill and among feedlots can vary greatly. Flaking to a similar density …

Kansas Agricultural Experiment Station Research Reports
Lactic acid spray washes are widely used as an antimicrobial intervention in the beef industry. Sprays are typically applied to the exterior of carcasses and subprimal cuts to reduce or eliminate potential pathogenic bacteria. While the efficacy of these washes has been proven, other questions remain about their effect on color attributes of meat when applied to subprimal cuts. The objective of this study was to determine the effect of a lactic acid subprimal wash on the color stability of beef chuck rolls.

Coarse Marbled Beef Is Juicier And More Flavorful Than Fine Or Medium Marbled Beef, K. R. Vierck, J. M. Gonzalez, T. A. Houser, E. A. Boyle, T. G. O'Quinn
Kansas Agricultural Experiment Station Research Reports
Beef palatability and eating experience is driven primarily by U.S. Department of Agriculture quality grade and marbling levels. Beef USDA quality grade consists of both marbling levels and maturity. Conventionally, marbling texture has not been a consideration of quality grades. Currently, only one study has assessed the effects of marbling texture on beef palatability. Despite this, preferences for fine or medium marbling exist with both packers and retailers, as approximately 75% of branded beef programs under the supervision of USDA-AMS require fine or medium textured marbling, which equates to losses of premiums for packers and producers (USDA, 2016). The objective …

Kansas Agricultural Experiment Station Research Reports
Ground beef is considered one of the major sources of animal protein in the U.S., accounting for approximately 40% of beef consumption per capita (USDA, 2011). Consumers’ concern about animal welfare, sustainable production, and low fat products has influenced purchasing decisions, resulting in an increased demand for grass-fed ground beef (U.S. Department of Agriculture, Agricultural Marketing Service, 2007). Grass-fed cattle are fed natural based forages or grass-hay, thus resulting in a higher deposition of omega-3 fatty acids in meat. Meat from grain-fed cattle has a lower omega-3 content due to the saturated and monounsaturated fatty acid profile found in a …

Kansas Agricultural Experiment Station Research Reports
Bull breeding soundness evaluations are often performed as a critical component of beef cow herd management to ensure that herd bulls have adequate semen quality, are physically capable of enduring the breeding season, and to determine the serving capacity per bull. Currently, there are approximately 30.3 million beef cows and 2.1 million bulls in the U.S. Depending on the breeding soundness evaluation failure rate, there are likely several hundred thousand bulls which will enter the beef market annually and a portion will be young bulls with the potential to be fed and sold to produce saleable meat of choice or …

Kansas Agricultural Experiment Station Research Reports
Liver abscesses are a significant problem in the United States’ cattle feeding industry, costing the industry an estimated $15.9 million annually in liver condemnation, trim losses, and reduced carcass weights and quality grades. Recent reported incidence rates of liver abscesses at slaughter range from 10 to 20%. Liver abscess incidence may be influenced by a number of factors including: breed, gender, diet, days on feed, cattle type, season, and geographical location. Liver abscesses typically occur secondary to rumen insults caused by acidosis or rumenitis. It has been proposed that pathogens associated with liver abscess formation enter the blood stream through …

Split Suckling, Birth Order, And Birth Weight Affects Colostrum Intake And Pre-Weaning Weight Gain, J. Morton, A. Langemeier, T. Rathbun, D. L. Davis
Kansas Agricultural Experiment Station Research Reports
Thirty sows (DNA Line 241, n = 10/treatment) and litters (sired by Line 600, pigs n = 412) were used to determine the effects of split suckling on immunocrit, colostrum intake, and growth of low birth weight pigs and pigs that farrow last in the birth order. Three treatments were used 1) control, all pigs suckled ad libitum; 2) weight based, the heaviest 6 pigs were removed for 1.5 h; or 3) birth order based, the first half of the litter was removed for 1.5 h. Over all litters, heavier pigs at birth had greater (P < 0.01) colostrum intake and pigs born in the last half of the litter had lower (P < 0.01) immunocrits (a measure of circulating immunoglobulins) than pigs born in the first half of the litter. Removing the heaviest 6 pigs for 1.5 h beginning 6 h after farrowing resulted in increased (P < 0.05) weight gain by d 7. A tendency (P = 0.15) for treatment × birth order interactions suggests that split suckling increased colostrum intake for the later born pigs.

A total of 529 litters of pigs (PIC TR4 × (Fast LW × PIC L02)) were used to examine the effect of sow lactation crate size on nursing pig litter performance and survivability. The sow portion of the farrowing crate was maintained at a constant length and width of 7.4 and 2.0 ft, respectively. To form the treatments, crate width was adjusted accordingly, taking space away from one sow’s crate to give it to another allowing for 3 crate widths: 4.8 (small), 5.4 (medium), and 6.0 ft (large). This allowed for blocks of 3 crates, where each treatment was represented. …
