    The American Society of Agricultural and Biological Engineers (ASABE) publishes a standard for identifying particle size by sieving (ASABE S319.4). However, this standard includes a number of options that allow the test ...
  • Kropf, Donald H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1989)
    The word "improved" in a commercial sense means "altered product characteristics to meet the consumers' real and perceived needs." The pork industry in the 90's must progress toward offering products designed to meet ...
  • Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1990)
    Particle size reduction has a great impact on efficiency of feed utilization. Decreasing particle size improves digestibility of nutrients by increasing surface area and allowing for greater interaction with digestive ...

    A total of 198 nursery age pigs were used to evaluate the difference in the occurrence of injection site abscesses between needle-free jet injection and conventional needle-and-syringe injection systems. Pigs were fed for ...
  • Davis, Duane L.; Stevenson, Jeffrey S.; Minton, J. Ernest (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Management and biological factors combine to limit litter size in swine herds. With present technology, improving litter size depends upon increasing the number born in the first litter and prolonging sow longevity. Methods ...
  • Richert, B.T.; Goodband, Robert D.; Tokach, Michael D.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    One hundred eighty-five sows were used to evaluate effects of the interrelationship between isoleucine and valine on sow and litter performance. Litter weight and weight gain at weaning increased as dietary valine, isoleucine, ...
  • Stevenson, Jeffrey S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Our objective was to determine the effectiveness of inducing estrus during lactation by reducing the nursing load of the sow between 2 and 4 weeks after farrowing. lactating sows were separated from their litters for ...
  • Goodband, Robert D.; Nelssen, Jim L.; Tokach, Michael D.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    We tested a probiotic/trace mineral mixture using a bacterial challenge model in high-health status pigs. We examined the influence of the mixture on growth performance, hematologic parameters, haptoglobin concentration, ...
  • Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    A total of 956 sows was used to determine the influence of a single injection of beta carotene, vitamin A, or the combination of beta carotene and vitamin A at weaning on subsequent reproductive performance. At weaning, ...
  • Laurin, J.L.; Richard, R.D.; Keesecker, D.R.; Goodband, Robert D.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1991)
    An on-farm field study utilizing 287 crossbred sows was conducted to investigate the influence of additional dietary lysine during lactation on sow and litter performance. At farrowing, sows were randomly assigned to one ...
