  • Effect of heifer source on reproductive performance, culling, marketing and profitability for a commercial heifer development program
    Lynch, J.M.; Lamb, G.C.; Grieger, D.M.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    A commercial heifer development operation purchased 483 weanling Angus × Hereford heifers from 11 sources. Heifers were fed a common silage-based diet through an initial developmental period and retained or culled based ...
  • Effect of urea level in protein supplements on performance by beef cows consuming low-quality, tallgrass-prairie forage
    Woods, B.C.; Cochran, R.C.; Mathis, C.P.; Heldt, J.S.; Olson, K.C.; Titgemeyer, E.C.; Grieger, D.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    One hundred thirty two Hereford × Angus cows grazing tallgrass-prairie range during winter were used to evaluate the effects of varying the amount of supplemental degradable intake protein (DIP) derived from urea on ...
  • 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 ...
  • Milking twice daily in the presence of a cow’s own calf fails to prolong postpartum anestrus
    Lamb, G.C.; Lynch, J.M.; Miller, B.L.; Grieger, D.M.; Stevenson, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    Six treatment s were initiated approximately 15 days after calving: 1) calf was weaned permanently from its dam (calf weaned; CW); 2) calf was present continuously with its dam but contact with the udder was prohibited ...
  • A novel estrus-synchronization program for anestrous and cycling, suckled, beef cows
    Forbes, W.L.; Corah, L.R.; Grieger, D.M.; Thompson, K.E.; Lamb, G.C.; Stevenson, J.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    We used four herds at three Kansas ranches to evaluate the potential of two new estrus synchronization strategies to increase estrus expression and fertility of 911 crossbred suckled beef cows. The treatments included: ...
  • Reproductive performance of replacement heifers implanted as young calves or at weaning
    Grieger, D.M.; Corah, L.R.; Spell, A.R.; Cook, D.L.; Butine, M.D.; Anderson, K. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    This study evaluated the effect of implanting potential replacement heifers (n=548) with Component E-C® (10 mg of estradiol and 100 mg of progesterone) between 45 and 120 days of age or at weaning (200 days of age) ...
