  • Effects of weaning age on costs and revenue in three-site production
    Main, R.G.; Dritz, S.S.; Tokach, M.D.; Goodband, R.D.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Two trials were completed to determine the effects of weaning age on growing pig costs and revenue within a three-site production system. Cost and revenue were measured by applying operationally dependant information to ...
  • Effects of weaning age on pig performance in three-site production
    Main, R.G.; Dritz, S.S.; Tokach, M.D.; Goodband, R.D.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Two trials (n = 5,728 weaned pigs) were conducted to determine the effects of weaning age (12 to 21.5 days) on pig performance in a three-site production system. The second trial also examined the effects of modifying nursery ...
  • Effects of weaning age on post-weaning belly nosing behavior and umbilical lesions
    Main, R.G.; Dritz, S.S.; Goodband, R.D.; Tokach, M.D.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Pigs (n=2272) were weaned at 12, 15, 18, or 21 days of age to determine the effect of weaning age on post-weaning belly nosing behavior and associated umbilical lesions. A reduction (quadratic, P<0.01) in belly ...
  • Linear effects of increasing weaning age in three-site production
    Main, R.G.; Dritz, S.S.; Tokach, M.D.; Goodband, R.D.; Nelssen, J.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)
    Two studies were conducted to measure the biologic and economic effects of weaning age in a three-site production system. Wean-to-finish growth and financial performance improved linearly as weaning age increased up ...
