Corn or sorghum grain in growing-finishing rations (with and without added copper, Vitamin E, Biotin or Aureo SP-250)

Pigs fed corn gained faster than those fed sorghum grain in one trial. The reverse was true in a second trial. Overall average daily gain figures were almost identical (1.67 lbs. per day for corn; 1.65 lbs. per day for sorghum). Average feed efficiency favored corn slightly (3.03 to 3.10). Adding 250 ppm copper to the diet significantly increased weight gain in one of five trials. Adding either vitamin E, biotin, or Aureo SP-250 did not significantly increase average daily gain or improve feed efficiency. Barrows gained 15% faster than gilts. Crossbred pigs gained 8% faster than the average of all purebreds.; Swine Day, Manhattan, KS, October 1, 197

Two antibiotic combinations with and without Vitamin E or fermentation product in rations for growing pigs

Growing pigs fed ASP-250 from birth to market gained equally as well as those fed TNT. Feed conversion values were quite similar. Adding a fermentation product or vitamin E to rations did not produce consistently better gains or feed efficiency.; Swine Day, Manhattan, KS, October 1, 197

Evaluation of antibacterial preparations on growth rate and feed efficiency of young pigs

Ninety-six young pigs were used to evaluate various antibacterial preparations on rate and efficiency of gain. Each of the antibacterial preparations increased rate of gain over pigs fed the non-medicated basal diet. There were no significant differences in daily gains of pigs fed ASP-250, CSP-250, Lincomix, Mecadox, or Stafac.; Swine Day, Manhattan, KS, November 11, 197

Relationship between body measurements and performance traits in boars

Fourteen body measurements were taken on 259 boars at 65 lbs. and again at 250 lbs. determine the relationship of external body dimensions with certain performance traits. Correlations between body measurements and growth tended to be extremely low for most factors. Our results do not support using body measurements as v1sual indicators of growth. This study suggests that performance testing is still the best way to predict a particular animal’s genetic potential.; Swine Day, Manhattan, KS, November 11, 197

Prevalence and Predictors of Social Support Utilization among Cancer Patients Undergoing Treatment

Background. The purpose of this study was to quantify the prevalence of cancer patients utilizing social support services while undergoing treatment and to identify patient and clinical factors associated with utilization of such services. Methods. This was a cross-sectional study. Surveys were distributed to three cancer clinics at 11 locations in the greater Kansas City metropolitan area in 2010. Study inclusion criteria included being at least 18 years old and undergoing treatment for cancer at the time of survey completion. Results. A total of 465 oncology patients completed surveys. Two-thirds (67.5%, n = 314) were undergoing treatment for cancer and were included in the final analysis. More than half (63.7%, n = 198) were female, and the average age was 58.9 ± 13.3 years. More than one-third (37.4%, n = 117) reported using cancer-related social support services. Additionally, 22% (n = 69) reported not using support services but were interested in learning more about those services. Patients had increased odds of having used support services if they were female (OR = 2.67; 95% CI = 1.47, 4.82), were younger adults, or had stage I-III (OR = 2.67; 95% CI 1.32, 5.26) or stage IV cancer (OR = 2.3; 95% CI 1.14, 4.75) compared to those who did not know their cancer stage. Conclusions. More than one-third of patients reported using social support services. A substantial portion of participants reported not using support services but were interested in learning more about those services. Increasing social support service utilization might be especially important to explore for men, those who do not know their cancer stage, and older adults

Lidar Sensors for Autonomous Landing and Hazard Avoidance

Lidar technology will play an important role in enabling highly ambitious missions being envisioned for exploration of solar system bodies. Currently, NASA is developing a set of advanced lidar sensors, under the Autonomous Landing and Hazard Avoidance (ALHAT) project, aimed at safe landing of robotic and manned vehicles at designated sites with a high degree of precision. These lidar sensors are an Imaging Flash Lidar capable of generating high resolution three-dimensional elevation maps of the terrain, a Doppler Lidar for providing precision vehicle velocity and altitude, and a Laser Altimeter for measuring distance to the ground and ground contours from high altitudes. The capabilities of these lidar sensors have been demonstrated through four helicopter and one fixed-wing aircraft flight test campaigns conducted from 2008 through 2012 during different phases of their development. Recently, prototype versions of these landing lidars have been completed for integration into a rocket-powered terrestrial free-flyer vehicle (Morpheus) being built by NASA Johnson Space Center. Operating in closed-loop with other ALHAT avionics, the viability of the lidars for future landing missions will be demonstrated. This paper describes the ALHAT lidar sensors and assesses their capabilities and impacts on future landing missions

Human Biodistribution and Dosimetry of 11C-CUMI-101, an Agonist Radioligand for Serotonin-1A Receptors in Brain

As a reported agonist,11C-CUMI-101 is believed to selectively bind the G-protein-coupled state of the serotonin-1A (5-HT1A) receptor, thereby providing a measure of the active subset of all 5-HT1A receptors in brain. Although 11C-CUMI-101 has been successfully used to quantify 5-HT1A receptors in human and monkey brain, its radiation exposure has not previously been reported. The purpose of this study was to calculate the radiation exposure to organs of the body based on serial whole-body imaging with positron emission tomography (PET) in human subjects

Will porcine somatotropin (pST) lower pork quality?

The types and diameters of muscle fibers from 30 barrows that had received daily injections of porcine somatotropin (pST) or a placebo and were fed dietary lysine at .6, .8, 1.0 or 1.2% were determined. Fiber data indicated that pST slightly increases the anaerobic metabolic potential of longissimus muscle. The higher levels of lysine caused enlargement of muscle cells. Earlier research has shown that this type of muscle biochemistry contributes to development of PSE muscle. Thus, use of pST in certain strains of pigs may lead to reductions in muscle quality.; Swine Day, Manhattan, KS, November 16, 198

Effects of daily porcine somatotropin administration on tile performance and carcass characteristics of finishing swine

One hundred forty-four pigs (72 barrows and 72 gilts) were utilized in six treatments with six pens each to evaluate four levels of daily porcine somatotropin (pST) injections (0, 1, 3, or 5 mg/d) in combination with diets containing 13 or 16% crude protein (CP). One randomly selected pig from each pen was slaughtered when it reached a weight between 230 and 240 lb. Daily feed intake (ADFI), tenth rib backfat, and estimated percentage of lean pork were reduced in pigs fed the 13% CP diet and injected with 3 mg/d pST compared to pigs fed the same diet and injected daily with a placebo. Feed intake was reduced in pigs fed the 16% CP diet and injected daily with 3 and 5 mg/d pST. Improvement in feed conversion (F/G), tenth rib backfat, and estimated percentage lean pork occurred when pigs fed the 16% CP diet were injected with 1 mg/d, with greater improvements occurring at the 3 and 5 mg/d levels of pST. The improvement in F/G and the greater magnitude of response observed in pigs fed 16% CP diets compared to the response of pigs fed the 13% CP diet indicate that both the performance and carcass characteristics of pigs injected with pST are dependent on the dietary CP content.; Swine Day, Manhattan, KS, November 16, 198
