Winter grazing can help reduce the need for purchased feeds in livestock production systems, when finishing cattle on pasture. Our objective was to evaluate the influence of stocking density and grazing stockpiled forage on performance of yearling st

SUMMARY Nutritionists have been challenged to find alternatives to synthetic methionine use in organic broiler diet formulation. Data do not exist on the ability of commercial broilers to partially meet amino acid requirements by foraging. In the cur

Much hill land pasture in the Appalachians is brush infested. Reclamation procedures which are low cost and require low input are needed to provide hill land pasture owners with ways to maintain production on these lands. A field experiment was carri

Decision making involves several criteria, something not always reflected in models. In this study, profitability, risk and environmental criteria are simultaneuosly used to rank alternative forage-resource production systems. Experimental data for W

Overseeding with red clover (Trifolium pratense L.) and stocking rate are factors that can affect composition and production of hill land pasture. A grazing experiment utilizing yearling beef steers (Bos taurus) was conducted using 3, 4, and 5 yearli

Extended grazing is a management system in which the usual grazing season is lengthened by utilization of hay fields for pasture. Extended grazing systems are a low-input alternative to conventional systems to the extent that they decrease the relian

Estimation of herbage mass is essential in pasture research and in making practical grazing management decisions. Sward height and a capacitance probe were evaluated as non-destructive measures of herbage mass at seven dates from April 16 to July 30

Angus-crossbred steers (n = 216) were used in a 3-yr study to assess the effects of winter stocker growth rate and finishing system on finishing performance and carcass characteristics. During winter months (December to April) steers were randomly al

To establish the effect of sward height, concentrate feeding time, and restricted time for grazing on forage utilization by grazing cattle, 32 crossbred beef (24 Angus and eight Hereford) cows (632 kg BW) and calves (104 kg BW) were grouped by weight
