  • Effect of monensin on weight gain, growth traits, and semen characteristics in yearling beef bulls
    Peters, C.W.; Laudert, S.B.; Corah, L.R.; Nichols, D.A.; Krehbiel, C.L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    Feeding the ionophore monensin to yearling beef bulls improved (P<.05) weight gain by 4.2%. Final hip height was similar between treatments, but bulls fed monensin had almost 1 cm greater (P<.01) scrotal circumference ...

  • Fertility after timed breeding using GnRH, PGF2, and norgestomet
    Thompson, K.E.; Stevenson, J.S.; Grieger, D.M.; Lamb, G.C.; Marple, T.J.; Corah, L.R.; Nichols, D.A.; McKee, R.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    At the KSU Purebred Unit, 164 purebred Angus, Hereford, and Simmental cows were used to test a new estrus-synchronization program using GnRH, PGF2, and norgestomet. Cows were inseminated after detected estrus, or in ...
  • Pregnancy rates in heifers and suckled beef cows after synchronized ovulation using PGF2", GnRH, and norgestomet
    Hoffman, D.P.; Stevenson, J.S.; Krehbiel, C.L.; Nichols, D.A.; McKee, R.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1996)
    Suckled cows and virgin heifers received a novel treatment that included PGF 2", GnRH, and norgestomet, with the objective of inducing estrus in prepubertal heifers and anestrous suckled cows, as well as synchronizing ...
  • Pregnancy rates in virgin heifers and suckled beef cows after synchronized ovulation using PGF2", norgestomet, and GnRH
    Hoffman, D.P.; Stevenson, J.S.; Krehbiel, C.L.; Nichols, D.A.; McKee, R.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1995)
    One disadvantage of most estrous synchronization programs is their inability to induce cycling in prepubertal heifers and anestrous suckled beef cows. Suckled cows and virgin heifers were treated with PG F2", ...
  • Ruminal effects of Rumensin during cold stress
    Robinson, J.B.; Ames, D.R.; Nichols, D.A. (Kansas State University. Agricultural Experiment Station, 1982)
    Two trials were conducted to determine the effects of Rumensin in cold-stressed cattle. Steers fed diets with and without Rumensin were exposed to cold stress (0 C) and thermoneutrality (20 C). Rumen volatile fatty acids ...
  • Using sprinklers to improve performance of heat-stressed feedlot cattle
    Nichols, D.A.; Ames, D.R.; Robinson, J.B. (Kansas State University. Agricultural Experiment Station, 1982)
    During a 56-day test, four pens of finishing cattle were sprinkled when dry-bulb temperatures exceeded 80 F. The performance of the cattle was compared with that of cattle in pens not sprinkled. Cattle in sprinkled pens ...
