Estimating The Effects Weather, Dry Matter Intake, And Body Weight On Daily Water Intake In Weaned Calves, Z. S. Mcdaniel, M. G. Gonda, C. L. Wright
SDSU Beef Day 2020 Summary Publication
Water is an essential nutrient and is required for growth, metabolism, lactation, and reproduction. However, water requirements for beef cattle have not been studied extensively since the 1950’s. The genetic potential for beef cattle has changed considerably since then. With the change in genetics, beef producers have observed increases in average daily gain and final body weight. The need for updated water requirements for beef cattle has also been exacerbated by global climate variability, drought conditions, and the need for efficient use of water resources. Given the increased productivity of cattle today relative to those of decades ago, increased water …

Sdsu Beef 2020 Increases Beef Industry Knowledge For Participants, C. Bakker, K. Underwood, J. K. Grubbs, J. Walker, C. Wright, K. Olson, W. Rusche, A. Blair
SDSU Beef Day 2020 Summary Publication
The objective of this study was to evaluate the effectiveness of the SDSU Beef 2020 program on increasing participant knowledge and impacting production practices. Unlike the pork or poultry industries, the US beef industry is not vertically integrated, and as a result the beef supply is managed by producers in a variety of roles. While these producers are knowledgeable about their specific sector, some may not be as familiar with the other aspects of beef production. South Dakota State University hosts an Extension program entitled Beef 2020 with the goal of bridging this knowledge gap.

Grazing Behavior, Forage Quality, And Intake Rates Of Livestock Grazing Pastures Occupied By Prairie Dogs, Jameson R. Brennan, Ken Olson, Patricia Johnson, Janna Block, Chris Schauer
SDSU Beef Day 2020 Summary Publication
Prairie dogs can reduce the carrying capacity on rangelands by up to 50% through direct consumption of vegetation and by clipping plants to improve predator detection. Studies have shown that forage quality and digestibility are greater on prairie dog towns than off-town, however research is lacking that quantifies rates of forage and nutrition intake by cattle grazing pastures occupied by prairie dogs. The objectives of this study were to 1) evaluate relationships between on- and off-town plant communities and cattle grazing locations to identify trends in livestock grazing behavior throughout the growing season, 2) evaluate diet nutrient composition and intake …
