Impact Of Stocking Rate And Grazing Management System On Profit And Pasture Condition
Section 2 of 12
July 1, 1995 - December 31, 2000
Introduction and Specific Objectives

Introduction: This research has compared continuous grazing to a flexible 12-paddock management-intensive system across four stocking rates for each system. Objectives include measurement of animal performance, pasture productivity and quality, species composition of the plant community, impact of grazing treatments on the soil bulk density and nutrient redistribution, and economic analysis of the systems. Year 2000 was the fifth and final year of the grazing study. Final measurements of species composition and nutrient distribution will be made in 2001. The same grazing treatments were applied to the same fields for all five years of the study to assess longer term effects of stocking rate and grazing management.
Specific objectives:
- Determine and model the relationships among forage supply, stocking rate, gain per acre, and average daily gain of yearling cattle either continuously grazing or rotationally grazing a mixed cool season grass-legume pasture.
- Measure the impact of stocking rate and method on pasture plant community.
- Monitor soil bulk density, soil fertility, and nutrient redistribution in each pasture system.
- Assess the impact of stocking rate and method on profitability in a stocker operation.
