  • Davis, Duane L.; Robl, J.M.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Control of estrus in gilts is theoretically possible by feeding a progestogen for 18 consecutive days. During the feeding period the progestogen suppresses estrus in all gilts and when withdrawn from the feed, all animals ...
  • Davis, Duane L.; Robl, J.M.; Nelssen, Jim L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Replacement gilts frequently do not fit smoothly into existing breeding and farrowing schedules because time of estrus cannot be predicted. Being able to program replacement gilts into a breeding herd would improve management, ...
  • Noll, M.T.; Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Four experiments involving 140 pigs were conducted to evaluate cow colostrum and twice-a-day feeding in artificial rearing of baby pigs. Piglets were allowed to nurse the sow for 15 hours after birth and allotted by litter ...
  • Allee, G.L.; Schoneweis, D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    One hundred fifty crossbred pigs averaging 21 lbs. initially were used to evaluate the effects of Banminth or Tramisol on performance of pigs housed in worm-contaminated dirt lots. Neither anthelmintic significantly affected ...
  • Myers, S.M.; Dikeman, Michael E.; Riley, Jack G. (Kansas State University. Agricultural Experiment Station, 1979)
    Analysis of traditional and later-maturing cattle types fed under accelerated (placed directly on the finishing ration) and conventional (back grounded on a growing ration before finishing) system, indicated large differences ...
  • Pruitt, J.; Schalles, R.R.; Harbers, L.H.; Owensby, Clenton E.; Smith, E.F. (Kansas State University. Agricultural Experiment Station, 1979)
    Polled Hereford cows on native Flint Hills pasture not supplemented until February lost more weight from December to February, lost less from February to May, and were in poorer condition before calving than cows supplemented ...
  • Thulin, A.J.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Ninety-six Yorkshire pigs, weaned at 5 to 6 weeks of age and averaging 9.5 kg (20.9 lbs.) were used to determine the effects of diets with increased fiber from oats, beet pulp, wheat bran, alfalfa meal or wheat shorts on ...
  • Schalles, R.R.; Fleck, A.T.; Kiracofe, G.H.; Corah, L.R. (Kansas State University. Agricultural Experiment Station, 1979)
    Heifers with faster gain the first and second winter (weaning to yearling and 18 months to 2 years old) had better production and reproduction than heifers with low or moderate gains. Gains during the first winter (weaning ...
  • Trotter, M.; Allee, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    A feeding trial and two phosphorus balance studies were conducted to compare the availabilities of phosphorus from high-moisture sorghum grain treated with propionic acid (1.2% acid, 23% moisture), grain stored in an oxygen ...
  • Fink, L.; Corah, L.; Kiracofe, G.; McKee, M. (Kansas State University. Agricultural Experiment Station, 1979)
    Forty-nine Simmental X Hereford and Hereford calves (24 bulls and 25 steers) were used to study the effect of Ralgro on growth, carcass traits, sex drive, sperm production, and development of sex organs. Approximately half ...
  • Thulin, A.J.; Allee, G.L.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Two hundred fifty eight, five-week old weanling pigs were used to evaluate various levels of dietary oats and oat hulls in swine diets by performance and incidence of diarrhea in pigs weaned at approximately 5 to 6 weeks ...
  • Sprott, L.R.; Corah, L.R.; Kiracofe, G.H.; McKee, M.; Schwartz, F.L. (Kansas State University. Agricultural Experiment Station, 1979)
    Heifers were given either one or two Ralgro implants or one DES implants during the suckling period with no obvious effect on later reproductive performance when the heifers were bred as yearlings. However, conception rates ...
  • Bartley, E.; Herod, E.; Bechtle, R.; Sapienza, D.; Brent, B. (Kansas State University. Agricultural Experiment Station, 1979)
    A series of artificial-rumen studies tested effects of Rumensin and lasalocid on rumen fermentation. At concentrations of 22, 44, and 66 ppm both depressed microbial protein synthesis. Both severely inhibited protein ...
  • Trotter, M.; Allee, G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Two feeding trials and three phosphorus balance studies were conducted to compare the effect of steam pelleting, extruding, and grinding on phosphorus availability. The results indicate that steam pelleting or extruding ...
  • Allee, G.L.; Schoneweis, D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Two trials using 216 pigs were conducted to evaluate effects various water medications have on performance and feed and water consumption by pigs weaned at 3 and 4 weeks of age. Water medication had no effect on pig ...
  • Corah, L.; Kiracofe, G.; McKee, M.; Schalles, R.R. (Kansas State University. Agricultural Experiment Station, 1979)
    Two years of research with nine herds indicated one of two yearling bulls with a herd usually will sire most of the calves. In six of the nine cases, the bull we pre-evaluated as most sexually active was the sire of the ...
  • Thulin, A.J.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    Two trials were conducted to evaluate the management practice of comingling litters one week before weaning to help reduce weaning stress. Pigs which were comingled before weaning gained slightly faster the first two weeks ...
  • Allee, G.L.; Nichols, David A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
    One hundred sixty Yorkshire barrows and gilts were used to evaluate supplemental heat and various types of hovers for finishing pigs during December, 1978, and January, 1979. Hovers constructed of plywood, straw, and plywood ...
  • Allee, G.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1979)
