Comparison of steer feedlot performance and carcass trait uniformly by method of sorting

Houghton, P.L.; Simms, D.D.; Higgins, James J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Long yearling steers (n=997) of various biological types from two origins were used to test performance and carcass trait uniformity of unsorted cattle, visually sorted cattle, and cattle sorted by ultrasound and hip ...
Cow/calf profitability: case studies of Kansas cattle producers

Simms, D.D.; Marston, T.T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Cost/return analyses of 56 Kansas cow/calf operations were summarized to determine the major factors influencing 1987 and 1988 cow herd profitability. Gross returns and costs on a per cow unit basis were extremely variable. ...
Effects of dietary energy on reproductive function and production in suckled beef cows

Perry, R.C.; Corah, L.R.; Beal, W.E.; Kiracofe, G.H.; Cochran, R.C.; Simms, D.D.; Brethour, J.R.; Stevenson, Jeffrey S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Twenty-eight Hereford x Angus cows were utilized to determine the effects of dietary energy level before and after calving on reproductive function and production in suckled beef cows. Low levels of dietary energy before ...
Effects of Finaplix® Synovex-S®, and Ralgro® implants, singularly or in combinations, on performance, carcass traits, and longissimus palatability of Holstein steers

Apple, J.K.; Simms, D.D.; Kuhl, Gerry L.; Dikeman, Michael E.; Kastner, Curtis L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Over the entire feeding period (249 d). Finaplix® (F) plus Synovex-S® (S)-implanted steers had higher (P<.05) daily gains than F+Ralgro® (R), F; and control (C) steers. All treatments produced higher (P<.05) daily gains ...
Relationship of milk production in Angus and Simmental cows with milk expected progeny differences (EPDs) and calf weaning weight

Marston, T.T.; Simms, D.D.; Schalles, R.R.; Zoellner, K.O.; Martin, L.C.; Fink, G.M. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Spring and fall calving Angus (n==86) and Simmental (n==96) cows at three different locations in Kansas were used to evaluate the relationships between milk production, Milk Expected Progeny Difference (Milk EPD), and ...
