Application Of Technology For Maximizing Lean Growth (1989), Robert D. Goodband Jan 1989

Application Of Technology For Maximizing Lean Growth (1989), Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

The swine industry is at a crossroads that either mayor may not change the way we produce pork in the future. As we head into the 90's, we are entering a new era in terms of growth promotion and carcass modification,which will produce overnight what would have taken generations to select for. Of the compounds tested, porcine somatotropin (pST) has the most potential to alter the structure of the swine industry. Many fear the application of this technology because of potential increases in pork production displacing and leading to fewer producers. Because pork quality will be improved tremendously (50% reduction …

Effect Of Diet Particle Size On Utilization Of Sunflower Oil Seeds In Nursery Pig Diets (1989), G E. Fitzner, T L. Weeden, Robert H. Hines, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

One hundred ninety-two weanling pigs were fed diets containing 15 or 25% sunflower oil seeds that were ground using a hammermill equipped with either a 1/8 or 3/16 in. screen. Average daily gain (ADG) of pigs fed the 25% sunflower seed diet ground through a 1/8 in. screen was similar to ADG of pigs fed the control diet or that with 15% sunflower seeds, although there was a reduction in ADFI. This indicates that finely ground sunflower seeds can be utilized in nursery pig diets up to 25% with no impairment in performance.; Swine Day, Manhattan, KS, November 16, 1989
