W053-A Sampling Of Thoughts And Opinions On Electronic Identification, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Over the years, the Center for Profitable Agriculture (CPA) has been involved with the USDA “Value-Added Development Grant” (VADG) program in various and numerous ways. In 2003, the Tennessee Farm Bureau Federation submitted a proposal to the VADG program for funding to assist in the development of a beef cattle marketing alliance in a 14-county area of the Upper Cumberland region of Tennessee. The project was funded for implementation through March 2005, and the CPA was included in the project as a cooperating partner.

One of the primary roles of the CPA in the project was to conduct an assessment …

Use Of Corn Co-Products In Soybean Hull-Based Feedlot Receiving Diets, Chad J. Mueller, Donald L. Boggs

South Dakota Beef Report, 2005

The use of different supplemental protein sources with soybean hulls in receiving cattle diets were evaluated using 200 Angus steer calves. Diets contained either corn and soybean meal (C-SBM), or soybean hulls with soybean meal (H-SBM), dried corn gluten feed (H-DCGF) or dried distillers grains plus solubles (H-DDGS). The replacement of corn (C-SBM) with soybean hulls (H-SBM) stimulated intake within the first 14 d of the receiving period and throughout the entire growing period (52 d). Supplementing soybean hulls with corn origin protein (COP) versus soybean meal did not result in any performance differences throughout the feeding period. Within the …

Sdsu Cow/Calf Teaching And Research Unit, Dick Pruitt, Kevin Vanderwal, Anna Drew

South Dakota Beef Report, 2005

The SDSU Cow/Calf Unit (CCU) provides cattle and facilities for numerous Animal Science and Range Science classes and a variety of research projects. The CCU also provides cattle for the SDSU Little International, Block & Bridle Club activities, numerous judging team workouts, and other activities that bring potential students to the SDSU campus. Kevin VanderWal and Anna Drew along with part-time student employees, manage the herd, collect research data, and assist with numerous beef cattle activities throughout the year.

Effects Of Grazing Residues Or Feeding Corn From A Corn Rootworm-Protected Hybrid (Mon 863) Compared With Reference Hybrids On Animal Performance And Carcass Characteristics, K. J. Vander Pol, Galen E. Erickson, N. D. Robbins, L. L. Berger, C. B. Wilson, Terry J. Klopfenstein, E. P. Stanisiewski, G. F. Hartnell

Department of Animal Science: Faculty Publications

One grazing and two feeding experiments were conducted to compare the feeding value of corn residue or corn grain from a genetically enhanced corn hybrid (corn rootworm-protected; event MON 863) with nontransgenic, commercially available, reference hybrids. In Exp. 1, two 13.7-ha fields, containing corn residues from either a genetically enhanced corn rootworm- protected hybrid (MON 863), or a near-isogenic, nontransgenic control hybrid (CON) were divided into four equal-sized paddocks. Sixty-four steer calves (262 ± 15 kg) were stratified by BW and assigned randomly to paddock to achieve a stocking rate of 0.43 ha/steer for 60 d, with eight steers per …

Pb1749-Mineral Nutrition Of Beef Cattle, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

The mineral status of the brood-cow herd affects reproduction, growth, milk production and health. All of these can affect profitability, yet the cost of improving mineral status is low compared to production returns.

This publication’s focus is on “mineral optimization,” which emphasizes the dynamics of minerals in living tissue. Cattle have evolved an elegant system for storing and retrieving minerals from various body stores as they are needed. The success of this system depends upon reliable replenishment from dietary sources.

Effectiveness Of Dried Distillers Grains With Solubles As A Replacement For Oilseed Meal In Supplements For Cattle Consuming Poor Quality Forage, Heidi Doering-Resch, Cody Wright, Kent Tjardes, George Perry, Kelly Bruns, Bradley Rops

South Dakota Beef Report, 2005

A two-year study was conducted at the South Dakota State University Southeast Research Farm in Beresford, SD, to determine the effects of feeding supplemental dried distillers grains with solubles (DDGS) on the performance of mid-gestation and non-gestating, non-lactating beef cows. Ninety-six gestating beef cows (initial BW = 1276.4 ± 22.2; initial BCS = 4.7 ± 0.09) and 96 non-gestating, non-lactating beef cows (initial BW = 1214.0 ± 20.8; initial BCS = 5.4 ± 0.10) were used for year 1 and year 2, respectively. Cows were stratified by weight and allocated to one of 15 pens. Pens were then randomly assigned …
