    Twenty-six Polled Hereford and Simmental-cross heifers that had not cycled by the beginning of the breeding season were given an ear implant and injected with an estrogen-progestogen compound. The implant was removed after ...
  • Stewat, R.E.; Mee, M.O.; Rettmer, I.; Stevenson, Jeffrey S. (Kansas Agricultural Experiment Station, 1992)
    Low thyroid activity (hypothyroidism) has been reported to decrease sexual behavior associated with reproduction in several species. Using estradiol benzoate (EB) and progesterone (P ), we attempted to induce 4 estrus ...
  • 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 ...
  • Stokka, Gerald L.; Brandt, Robert T., Jr.; Edwards, A.J.; Spire, M.F.; Smith, J.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1993)
    Twenty-four finishing steers (758 lb) were subcutaneously vaccinated and revaccinated 31 days later with 1) sterile saline, 2) a clostridial perfringens C&D toxoid, or 3) a 7-way clostridial bacterin-toxoid to evaluate ...
  • 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, ...
  • Goodband, Robert D.; Langbein, Kari Beth; Tokach, Michael D.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2013)
    A total of 1,188 finishing pigs (PIC 337 × 1050, initially 80.1 lb) were used in a 92-d experiment to determine the influence of providing phytase above that needed to meet the P requirement for growth performance and ...
