  • Optimal parity distribution – when is the best time to cull sows?
    Dhuyvetter, K.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    The economic impact of alternative sowculling strategies was examined by simulating costs and returns for a farrowing-to-weaning swine operation. Culling strategies considered were to sell sows after parity 1 (P1) ...
  • The optimum isoleucine:lysine ratio in starter diets to maximize growth performance of the early-weaned pig
    James, B.W.; Goodband, R.D.; Tokach, M.D.; Nelssen, J.L.; DeRouchey, J.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    A total of 360 weanling pigs (initially 12.3 lb BW and approximately 18 d of age) was used in a 14-d growth assay to determine the optimal isoleucine:lysine ratio to maximize growth performance. The 12 experimental ...
  • The pH of spray-dried blood meal does not influence nursery pig performance
    DeRouchey, J.M.; Nelssen, J.L.; Tokach, M.D.; Goodband, R.D.; Dritz, S.S.; Woodworth, J.C.; James, B.W.; Webster, M.J.; Real, D.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Two studies were conducted to evaluate the effects of spray-dried blood meal and its pH on nursery pig performance. Spray-dried blood meal pH decreases as storage time increases prior to spray drying. In Exp. 1, addition ...
  • Sorting growing-finishing pigs by weight fails to improve growth performance or weight variation
    O’Quinn, P.R.; Dritz, S.S.; Goodband, R.D.; Tokach, M.D.; Swanson, J.C.; Nelssen, J.L.; Musser, R.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    A trial was conducted to determine the effects of sorting pigs by body weight at placement on growth performance and weight variation at finishing. Unsorted pigs and heavy sorted pigs had higher ADG than medium or light ...
  • Use of infrared thermography to evaluate differences in mean body surface temperature and radiant heat loss in growing pigs
    Loughmiller, J.A.; Spire, M.F.; Tokach, M.D.; Dritz, S.S.; Nelssen, J.L.; Goodband, R.D.; Hogge, S.B.; James, B.W. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Eighty barrows were used in two experiments to determine the relationship between feed intake or dietary energy concentration and mean body surface temperature (MBST) and mean body surface radiant heat loss (MBSL) as ...
  • Variation in the digestiility of amino acids in soybean meal from a single processing plant
    Lee, D.J.; Hancock, J.D.; DeRouchey, J.M.; Maloney, C.A.; Dean, D.W.; Cao, H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Digestibilities of amino acids among samples of soybean meal (SBM) collected during a fall harvest season (4 collections made 15 d apart) were similar, except that true digestibility from tryptophan was lower for a sample ...
