Evaluation of Long-Acting Eprinomectin Compared to Conventional Anthelmintics in Cow/Calf Production
… were greater (P0.20) between CON and treated cows. Day 14 BCS tended (P=0.07) to be greater for CON compared to treated cows. Also, BCS was greater (P=0.01) and hair coat score was lower (P</p>

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
… forages to fill the summer slump gap in production of cool-season grasses. Small plot experiments were initiated in summer of 2008 in Kentland Farm, Northern Piedmont AREC and Shenandoah AREC, Virginia. Treatments included endophyte-infected tall fescue (KY31 E+), endophyte free tall …

Economic analyses of the effects of calving season on beef cow-calf-forage systems
Important implications of the study are: beef cow-calf production is competitive over a wide range of beef prices and it may increase farm returns to feed small amounts of corn silage rather than grow additional pasture even when the weaned steer calf-corn ratio is quite low.

Forage Utilization and Nitrogen Management of Tall Fescue Stockpiled for Winter Grazing
… offers a beneficial environment for stocker and cow-calf production. Abundant tall fescue grass offers a feed source that has been underutilized. These studies evaluated how nitrogen rate and source can affect yield and nutritional quality of fall stockpiled tall fescue, and how grazing methods …

Evaluation of hay-type and grazing tolerant alfalfa cultivars in season-long or complementary rotational stocking systems for beef cows
<p>Legume persistence and forage and cow-calf production were evaluated on rotationally stocked pastures in either a season-long or complementary system. In 1997, six 2.02 hectare pastures were seeded with smooth bromegrass (SB), a mixture of a grazing tolerant (GT) alfalfa and SB, or a mixture of …

Modeling Greenhouse Gas Emissions and Net Return Implications for Cow-Calf Producers in the Ozark Highlands
<p>Cow-calf producers in the Ozark Highlands region are under continuous pressure to improve economic efficiency. Additionally, estimating greenhouse gas (GHG) emissions from cow-calf and forage production processes may become increasingly important as policy makers seek to mitigate or reduce …

Program Feeding Strategies for Reducing Costs of Wintering Beef Cows
… evaluate program-fed diets for maintaining beef cows. The largest expense in a cow/calf production system is the cost associated with maintaining the producing cow through the winter months. This research focused on evaluating the performance, financial, and environmental impacts of using …

Modifying a Cow-Calf Biophysical Simulation Model for Analyses of Alternative Enterprises
<p>Cow-calf producers in the United States, tasked with providing beef calves for the beef industry, have had a multitude of difficulties to overcome in recent years. Producers in northwest Arkansas were negatively impacted by high hay prices coupled with low beef cattle market prices due to severe …

Supplementation Strategies for Growing and Finishing Beef Cattle on Tall Fescue Pastures in the Southeast
… consistent rainfall allow for abundant forage production. Tall fescue dominated pastures in this region provide a high-quality forage source to support consistent cattle growth and production. Furthermore, the nearly year-round grazing potential serves as a cost-effective feed source. …
