Effects Of Modified Tall Oil And Creatine Monohydrate On Growth Performance, Carcass Characteristics, And Meat Quality Of Growing-Finishing Barrows (1999), P R. O'Quinn, B S. Andrews, J C. Woodworth, Robert D. Goodband, John A. Unruh, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

A trial was conducted to evaluate the effects of modified tall oil (MTO; .50% of the diet) and creatine monohydrate (CMH; 25 g/pig/day for 10 days prior to slaughter) on performance, carcass characteristics, and meat quality of finishing barrows. Feeding MTO improved ADG and F/G during the growing phase and improved F/G over the entire trial and during the 10 day CMH loading period. Feeding MTO reduced backfat, but neither CMH nor MTO affected other carcass characteristics or meat quality measures at 24 h postmortem. These data suggest that MTO improves performance and reduces backfat with little effect on meat …

Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Bacon Characteristics (1999), A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach Jan 1999

Influence Of Dietary Supplementation Of Modified Tall Oil, Chromium Nicotinate, And L-Carnitine On Bacon Characteristics (1999), A T. Waylan, P R. O'Quinn, J C. Woodworth, K Q. Owen, John A. Unruh, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred (PIC) gilts were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet), chromium nicotinate (0 or 50 ppb), and L-carnitine (0 or 50 ppm) on bacon quality characteristics. Supplementation of MTO improved bacon slice firmness. Dietary additions of MTO, chromium nicotinate, and L-carnitine to diets for growing and finishing swine had minimal effects on other bacon characteristics. Therefore, producers probably can take advantage of any improvements in production or carcass cutability from these feed supplements without affecting bacon quality.; Swine Day, Manhattan, KS, November 18, 1999

On-Farm Salmonella Testing: Perspectives Of Pork Producers (1999), D R. Mark, Michael A. Boland, John A. Fox

Kansas Agricultural Experiment Station Research Reports

Pork producers in Kansas were surveyed to determine their attitudes regarding onfarm Salmonella testing and to provide estimates ofthe costs ofcollecting hide, fecal, or blood samples from live pigs. Veterinarians and Cooperative Extension Service personnel were cited most frequently as the most preferred groups for monitoring and verification. Results ofthe survey indicate that pork producers may be willing to conduct on-farm Salmonella testing, if they can recover the costs of sample collection. The sampling costs ranged from $1.76 to $4.72 per pig, depending on the method of sample collection.; Swine Day, Manhattan, KS, November 18, 1999

Kansas Agricultural Experiment Station Research Reports

Three hundred twenty, 24 lb nursery pigs were fed for 19 days to compare the effects of increasing dietary lysine from L-Iysine HCl (L-Lys) or Peptide Plusâ„¢ (PP) on growth performance. Three dietary treatments (1.025, 1.15, and 1.275% lysine) were each formulated with L-Lys and PP. Negative and positive control corn-soybean meal-based diets were formulated to .90 and 1.275% lysine, respectively. Increasing dietary lysine to 1.275% from L-Lys or PP resulted in increased performance; however, pigs fed the positive control diet had the best overall performance.; Swine Day, Manhattan, KS, November 18, 1999

Infrared Thermography Of Swine Body Surface Temperatures And Associated Rectal Temperatures During An Acute Respiratory Disease Challenge (1999), J A. Loughmiller, M F. Spire, B W. Fenwick, S Hogge, J Foster, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

An acute Actinobacillus pleuropneumonia challenge was used to study changes in rectal and radiant surface temperatures over 18 h. From 3.5 to 15 h after challenge, rectal temperatures were elevated in challenged pigs compared to nonchallenged controls. From 6 through 18 h after challenge, infrared surface temperature was higher for challenged pigs versus control nonchallenged pigs. Correlation coefficient analysis indicated that surface temperature and rectal temperature were moderately correlated. These results indicate that infrared thermography will detect changes in body surface temperature associated with the acute phase febrile response and has potential as a diagnostic tool for assessing systemic changes …

Sources Of Variability In Fed-Cattle Grid Pricing (1999), J.L. Graff, Ted C. Schroeder Jan 1999

Sources Of Variability In Fed-Cattle Grid Pricing (1999), J.L. Graff, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Price variability among carcasses increases with a change from live-weight to dressedweight to grid pricing. Grid pricing has the largest price variability, because the price for each carcass is influenced by all of the components of the grid, rather than all cattle selling for the same live or dressed price. Therefore, producers selling on a grid need to have knowledge about the expected carcass merit of their cattle. We used data on 11,703 head of cattle to determine which grid pricing components influence price variability the most and to measure how much price variability increases from grid pricing, relative to …

Vegetative Filters For Improving Environmental Quality (1999), P.K. Kalita, Joseph P. Harner Jan 1999

Vegetative Filters For Improving Environmental Quality (1999), P.K. Kalita, Joseph P. Harner

Kansas Agricultural Experiment Station Research Reports

Nonpoint source pollution from agricultural areas has been recognized as a major contributor of surface and groundwater quality problems. Sediments, pesticide and nutrient runoffs, and microbial pathogens from farmlands may severely affect quality of water resources. A majority of Kansas river basins contains high concentrations of fecal coliforms, nitrogen, phosphorus, and sediments. The use of vegetative filters strips (VFS) has been identified as one of the best management practices to reduce pollutant concentrations in surface water sources. Vegetation planted between pollutant sources and receiving water accomplishes this by filtration, deposition, infiltration, adsorption, volatilization, plant uptake, and decomposition processes. The effectiveness …

Selection Response For Feed Conversion And Growth Traits In Polled Hereford Cattle (1999), J.B. Jr. Glaze, R.R. Schalles Jan 1999

Selection Response For Feed Conversion And Growth Traits In Polled Hereford Cattle (1999), J.B. Jr. Glaze, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Direct and correlated responses to selection for improved feed conversion were estimated from performance records of 1459 Polled Hereford cattle born from the spring of 1967 through the spring of 1979. Data were analyzed using a multiple-trait, derivative-free, restricted maximum likelihood (MTDFREML) procedure. A full animal model was used to calculate genetic and phenotypic (co)variances. The withinherd breeding values that resulted from the solution of the mixed model equations were regressed on year to create selection response curves. Feed conversion was shown to respond favorably to direct selection, with feed/gain changing -.005 per year.

Market Hog Price Discovery (1999), Ted C. Schroeder, J Mintert

Kansas Agricultural Experiment Station Research Reports

Cash hog markets are declining in importance, and use of formula pricing of market hogs is increasing. Producers need more information to assist them in price discovery and formula price negotiations with pork packers. Lean hog futures and pork wholesale plus by-product values offer useful pricing information for producers. However, using these markets as sources ofprice information is not without challenges. This report highlights issues involved in hog market price discovery and examines the usefulness of lean hog futures and wholesale pork values in price discovery.; Swine Day, Manhattan, KS, November 18, 1999

Examination Of Stocking Density And Marketing Strategies In A Commercial Production Environment (1999), Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

The influence of stocking density (7.4 or 6.6 sq ft per pig) and marketing strategy (0, 1, or 2 sorts before closeout) was examined in a commercial production environment. No interaction between stocking density and marketing strategy was observed. Higher stocking density had no negative effects on growth performance or carcass characteristics. The major advantage of one or two sorts was a reduction in sort loss of $.27/cwt carcass ($.52/pig) compared to no sorts. No differences were found between one and two sorts under the packer matrix used in this study.; Swine Day, Manhattan, KS, November 18, 1999

Regardless of fat source, MTO improved belly firmness but did not influence growth performance. Gilts were leaner, had increased loin muscle area, and had softer bellies compared to barrows. Added fat decreased ADFI and improved F/G. Pigs fed PF had the best F/G, but the fattest carcasses and softest loins and bellies.; …

Kansas Agricultural Experiment Station Research Reports

Seventy-two crossbred (PIC) barrows were used to determine the influence of feeding modified tall oil (MTO, 0 or .5% of diet) and vitamin E (0, 10, or 50 IU/lb of feed) on display color stability, Warner-Bratzler shear, and sensory panel traits of pork chops. Feeding MTO in combination with high levels of vitamin E to pigs during both the growing and finishing phases improved display color stability and delayed lipid oxidation of the pork loin chops without affecting tenderness and sensory evaluations. Therefore, feeding swine MTO (.5%) with high levels of vitamin E (50 IU/lb of feed) can increase the …
