Determining the influence of different levels of urea supplementation when beef cows grazing winter pasture are supplemented at different frequencies during the prepartum period

Farmer, C.G.; Cochran, R.C.; Wickersham, T.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)

One hundred sixty spring-calving Hereford × Angus cows grazing low-quality, tallgrass-prairie range during the winter of 2000-2001 were supplemented before calving either daily or three times weekly. The supplement ...
Effect of ruminal versus postruminal administration of degradable protein on utilization of low-quality forage by beef steers

Bandyk, C.A.; Cochran, R.C.; Wickersham, T.A.; Titgemeyer, E.C.; Farmer, C.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)

Twelve ruminally fistulated steers were used to evaluate the effects of supplying a highly degradable protein source (casein) both ruminally and postruminally on intake and digestibility of low-quality native hay. Both ...
Effect of source of carbohydrate and degradable intake protein in supplements on low-quality forage utilization by steers

Arroquy, J.I.; Cochran, R.C.; Wickersham, T.A.; Llewellyn, D.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2002)

Twelve ruminally fistulated steers were used in an experiment to study the impact of the source of carbohydrate (CHO) and degradable intake protein (DIP) in supplements on low-quality forage utilization. Treatments ...
Effect of supplemental carbohydrate type and amount of ruminally degradable protein on utilization of tallgrass-prairie hay by beef steers

Arroguy, J.I.; Cochran, R.C.; Villarreal, M.; Wickersham, T.A.; Llewellyn, D.A.; Titgemeyer, E.C.; Johnson, D.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)

This experiment determined the impact of type of supplemental carbohydrate and amount of supplemental ruminally degradable protein (RDP) on intake and digestion of prairie hay. Fourteen ruminally fistulated beef steers ...
Effects of frequency of supplementation on performance of beef cows grazing winter pasture

Farmer, C.G.; Cochran, R.C.; Simms, D.D.; Klevesahl, E.A.; Wickersham, T.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)

One hundred twenty spring-calving Hereford × Angus cows grazing low-quality tallgrass-prairie forage during the winter of 1998 were fed a 43% crude protein supplement 2, 3, 5, or 7 days a week. Supplement was fed at ...
Effects of frequency of supplementation on the intake and digestion of low-quality forage by beef steers

Farmer, C.G.; Cochran, R.C.; Simms, D.D.; Klevesahl, E.A.; Wickersham, T.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2000)

A 43% CP (dry basis) supplement was fed to 16 ruminally fistulated steers on 2, 3, 5, or 7 days a week. Supplement was offered at .36% BW (dry basis) daily for steers that received supplement every day. For other ...
Influence of low-level fall protein supplementation on forage intake, diet digestion, and selection by beef steers grazing tallgrass-prairie range

Llewellyn, D.A.; Cochran, R.C.; Marston, T.T.; Farmer, C.G.; Wickersham, T.A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)

This study evaluated the effect on forage utilization of providing a limited quantity of a high-protein (40% crude protein) supplement to beef cattle grazing tallgrass prairie during the fall. Sixteen ruminally fistulated ...
Influence of low-level fall supplementation with a self-fed, high-protein supplement and level of winter supplementation on performance of beef cows grazing tallgrass-prairie range

Wickersham, T.A.; Cochran, R.C.; Dhuyvetter, D.V.; Grieger, D.M.; Farmer, C.G. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)

An experiment was conducted to determine the effect of providing a small amount of a high-protein supplement during the fall and effects of increasing subsequent level of winter supplementation on cow-calf performance. One ...
Influence of low-level supplementation with a high-protein feed on performance of beef cows grazing tallgrass-prairie range during the fall

Llewellyn, D.A.; Cochran, R.C.; Martson, T.T.; Grieger, D.M.; Farmer, C.G.; Wickersham, T.A.; Simms, D.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)

An experiment was conducted to evaluate the effect of hand feeding a limited quantity of a high-protein supplement during the fall grazing period on cow and calf performance. The time of initiation of supplementation was ...
Microbial use of recycled urea is dependent on the level and frequency of degradable intake protein supplementation

Wickersham, T.A.; Titgemeyer, E.C.; Cochran, R.C.; Wickersham, E.E.; Moore, E.S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)

Protein supplementation increases utilization (intake and digestion) of low-quality forage and ultimately animal performance. Despite its effectiveness, protein supplementation is often expensive. One strategy to reduce ...
Relative value of ruminally degradable and undegradable protein on the utilization of low-quality prairie hay by steers

Wickersham, T.A.; Cochran, R.C.; Titgemeyer, E.C.; Farmer, C.G.; Klevesahl, E.A.; Arroquy, J.I.; Johnson, D.E.; Gnad, D.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)

An experiment was performed to investigate the impact of providing six levels of ruminally degradable protein (RDP; protein that is available to ruminal microbes) in combination with two levels of ruminally undegradable ...
Supplementation with degradable intake protein increases low-quality forage utilization and microbial use of recycled urea

Wickersham, T.A.; Titgemeyer, E.C.; Cochran, R.C.; Wickersham, E.E.; Gnad, D.P. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)

A common production practice throughout the United States is to supplement protein to cattle consuming low-quality forage (forage with a crude protein content of less than 7%) in order to improve animal performance ...
Supplementation with undegradable intake protein increases utilization of low-quality forage and microbial use of recycled urea

Wickersham, T.A.; Titgemeyer, E.C.; Cochran, R.C.; Wickersham, E.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2007)

Low-quality forage utilization (intake and digestion) is improved by protein supplementation. Typically, the recommendation is to select supplements that are high in degradable intake protein because this fraction of the ...
Timed-insemination of beef heifers using Cosynch with or without MGA

Grieger, D.M.; Wickersham, T.A.; Cochran, R.C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)

Our purpose was to determine if feeding melengesterol acetate (MGA) for 1 week in combination with gonadotropin-releasing hormone (GnRH) and prostaglandin-F2" (PGF) would better synchronize heifers for timed artificial ...
