  • Effects of a heat-stable yeast product in pelleted diets for weanling pigs
    Maloney, C.A.; Hancock, J.D.; Hines, R.H.; Cao, H.; Nemecek, C.S.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    The results from two experiments showed that a heat-stable yeast product survived well in diets that were steam conditioned at 158 to 176°F and pelletized. Also, inclusion of .2% yeast product resulted in a greater rate ...
  • Effects of conditioners (standard, long term, and expander) on pellet quality and growth performance in nursery pigs
    Johnston, S.L.; Hines, R.H.; Hancock, J.D.; Behnke, K.C.; Maloney, C.A.; Traylor, S.L.; Sorrell, S.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    In our first experiment, digestibilities for DM, N, and GE were greater and F/G was better for pigs fed pelleted diets than for pigs fed meal diets. However, we observed no advantages in ADG or F/G with long-term conditioning. ...
  • Effects of diet manipulation on growth performance, carcass characteristics, and meat quality of intact male pigs
    Maloney, C.A.; Hines, R.H.; Hancock, J.D.; Cao, H.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Castrates were predictably less efficient, had greater ADFI, and tended to have more BF than contemporary boars. Castration decreased detection of boar taint, but alterations of dietary CP, pH, and antimicrobial level from ...
  • Effects of dietary electrolyte balance on sow and litter performance, blood chemistry, and urine chemistry in lactating sows
    DeRouchey, J.M.; Hancock, J.D.; Hines, R.H.; Maloney, C.A.; Lee, D.J.; Dean, D.W.; Cao, H.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Decreasing the dietary electrolyte balance (dEB) in diets for lactating sows from 500 to 100 mEq/kg increased piglet survivability but had no effect on litter weight gain. Decreased dEB reduced pH and bacteria in the ...
  • Effects of expanded whole soybeans on growth performance and nutrient digestibility in nursery pigs
    Cao, H.; Hancock, J.D.; Hines, R.H.; Behnke, K.C.; Jiang, J.M.; Park, J.S.; Froetschner, J.R.; Maloney, C.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    As expected, ADG, ADFI, F/G, and digestibility of DM and N were improved in nursery pigs when cone pressure was increased during dry and moist expanding of whole soybeans. These response were quadratic for the most part, ...
  • Effects of expander conditioning of corn- and sorghum-based diets on pellet quality and performance in finishing pigs and lactating sows
    Johnston, S.L.; Hancock, J.D.; Hines, R.H.; Behnke, K.C.; Kennedy, G.A.; Maloney, C.A.; Traylor, S.L.; Sorrell, S.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Pellet durability index was similar for sorghum- vs com-based diets but was greater for expander-conditioned pellets than standard-conditioned pellets. For finishing pigs, ADG, F/G, and carcass measurenlents were similar ...
  • Effects of free fatty acid concentrations in choice white grease on growth performance and nutrient digestibility in weanling pigs
    DeRouchey, J.M.; Hancock, J.D.; Hines, R.H.; Cao, H.; Maloney, C.A.; Dean, D.W.; Lee, D.J.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    As much as 53% free fatty acids in choice white grease did not adversely affect piglet performance. Thus, concentration of free fatty acids, if they are not otherwise damaged or rancid, is not an acceptable measure of ...
  • Effects of inorganic and organic acids on urine pH in lactating sows
    DeRouchey, J.M.; Hancock, J.D.; Hines, R.H.; Coa, H.; Lee, J.; Maloney, C.A.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Some swine practitioners are advocating the use of dietary acidifiers to reduce urine pH and, thereby, reduce the incidence of urinary tract infections. In our experiment, sows fed an inorganic (phosphoric) acid had lower ...
  • Effects of rancidity in choice white grease on growth performance and nutrient digestibility in weanling pigs
    DeRouchey, J.M.; Hancock, J.D.; Hines, R.H.; Cao, H.; Maloney, C.A.; Dean, D.W.; Lee, D.J.; Park, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)
    Our data suggest that adding slightly rancid choice white grease with peroxide values of 40 mEq/kg and less and p-anisidine values of 10.6 and less to diets will not decrease growth performance in nursery pigs. However, reduced ...
  • Enzyme additions to sorghum-based diets for finishing pigs
    Park, J.S.; Hancock, J.D.; Hines, R.H.; Maloney, C.A.; DeRouchey, J.M.; Cao, H.; Lee, D.J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Three experiments were conducted to determine the effects of a sorghum-specific enzyme supplementation on growth performance of finishing pigs. Although positive trends occurred, the sorghum-specific enzymes used in our ...
  • Expander processing and enzymes for a wheat-based diet for finishing pigs
    Park, J.S.; Hancock, J.D.; Hines, R.H.; Behnke, K.C.; Kennedy, G.A.; DeRouchey, J.D.; Lee, D.J.; Maloney, C.A.; Cao, H, (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1998)
    Overall ADG and ADFI were not affected, but feed efficiency was improved with pelleting and further improvements resulted from expander processing. In a second experiment, enzyme supplementation to mash, but not pelleted, ...
  • 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 ...
