One In The Hand Worth Two In The Bush? Reproductive Effort Of Young Males Is Not Affected By The Presence Of Adult Males, Kevin L. Monteith, Kyle B. Monteith, Jonathan A. Jenks, Rhiannon P. Jakopak

Natural Resource Management Faculty Publications

Reproduction is a costly endeavor, and most large, long-lived, and iteroparous mammals exhibit conservative life-history tactics wherein an individual may forego or abandon a reproduction event for the sake of survival. Nevertheless, risks and benefits associated with reproduction are not equal across males and females, nor across their life. Whereas expenditure for females is associated with rearing young (e.g., lactation), expenditure for males occurs with securing mating opportunities. Young males may be more successful when dominant males are lacking, but it is less clear whether—and at what cost—young males will expend effort when those opportunities arise. We designed an experiment …

Causal Explanations For The Evolution Of ‘Low Gear’ Locomotion In Insular Ruminants, Roberto Rozzi, Sara Varela, Pere Bover, Jeff Martin

Natural Resource Management Faculty Publications

Aim: Mammals on islands often undergo remarkable evolutionary changes. The acquisition of ‘low gear’ locomotion, namely short and robust limb elements, has been typically associated with the island syndrome in large mammals and, especially, ruminants. Here we provide an investigative framework to examine biotic and abiotic selective factors hypothesized to influence evolution of this peculiar type of gait. Location: Islands worldwide.
Taxon: Bovidae.
Methods: We calculated response variables associated with ‘low gear’ locomotion in 21 extinct and extant insular bovids. We assembled data on the physiography of 11 islands and on life history and ecological traits of the focal taxa. …

Heavy Winter Patch Grazing As An Alternative To Prescribed Burning On The Northern Great Plains, Jameson R. Brennan, Patricia Johnson, Ken Olson, Jennifer Lutze

SDSU Beef Day 2020 Summary Publication

Among management systems intended to increase heterogeneity on the landscape, patch burn grazing (PBG) is by far the most prominent and researched method. Though prescribed burning is seen as a healthy disturbance in grassland ecosystems, many landowners in the Northern Great Plains have an aversion to fire. This is due to safety and liability concerns as well as concerns over forage losses and limitations of labor, equipment, and insurance to successfully carry out prescribed burns. Therefore, there is a critical need to evaluate alternative, non-fire management strategies that will encourage rangeland heterogeneity. A study was conducted in 2017-2018 at the …

Evaluation Of Variation Attributable To Lab And Technician For Measurements Of Beef Carcass Traits Made Using Ultrasound, B. Schmidt, M.D. Macneil, M. G. Gonda

SDSU Beef Day 2020 Summary Publication

National cattle genetic evaluations assume technician and imaging lab do not contribute to phenotypic variation when measuring carcass traits by ultrasound. The objective of this study was to estimate variance components of ultrasound carcass measurements, specifically variance contributed by ultrasound technician and imaging laboratory. Accounting for technician and imaging lab variation may increase accuracy of genetic predictions for carcass traits. Ultrasound carcass predictions for ribeye area (REA), percent intramuscular fat (IMF), and backfat (BF) were provided by the American Angus Association (AAA; n=281,982 animals), American Hereford Association (AHA; n=49,602), and American Simmental Association (ASA; n=59,576) for a total of 391,160 …

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.
