GRAZED CORN RESIDUE IS A LOW-COST FORAGE RESOURCE FOR WINTERING BEEF COWS. WITH APPROPRIATE STOCKING RATES, MATURE, PREGNANT BEEF COWS CAN OFTEN BE WINTERED WITHOUT SUPPLEMENTATION. HOWEVER, COW RESPONSE IS VARIABLE, AND TOOLS ARE LIMITED FOR PREDICTING AND MANAGING VARIABILITY. WE DEVELOPED A STRATEGIC ON-FARM PARTICIPATORY RESEARCH PROJECT TO IDENTIFY KEY AGRONOMIC, ENVIRONMENTAL, AND MANAGEMENT DRIVERS AFFECTING VARIABILITY IN BEEF COW BODY CONDITION RESPONSE WHEN GRAZING CORN RESIDUE AND DEVELOP ADAPTIVE GRAZING MANAGEMENT STRATEGIES TO OVERCOME THE CAUSES OF BEEF COW BODY CONDITION DECLINE. PROJECT OBJECTIVES ARE TO 1) IDENTIFY POTENTIAL AGRONOMIC, ENVIRONMENTAL, AND MANAGEMENT DRIVERS FOR OBSERVED VARIABILITY IN BEEF COW RESPONSE WHEN GRAZING CORN RESIDUE, 2) DEVELOP PREDICTION EQUATIONS FOR ENERGY CONTENT OF CORN HUSKS AND LEAVES, AND 3) DEVELOP ADAPTIVE MANAGEMENT STRATEGIES TO REDUCE VARIABILITY IN BEEF COW BODY CONDITION WHEN GRAZING CORN RESIDUE.THE PROJECT WILL PRODUCE ADAPTIVE GRAZING MANAGEMENT STRATEGIES BY PROVIDING SOLUTIONS PRODUCERS CAN IMPLEMENT TO HELP MITIGATE RISKS OF VARIABLE CORN RESIDUE GRAZING RESPONSE. EXTENSION EDUCATORS AND SPECIALISTS WORKING WITH PRODUCERS THROUGHOUT THE PROJECT WILL ENSURE KEY DRIVERS OF VARIABILITY ARE PROPERLY IDENTIFIED WITH MANAGEMENT STRATEGIES MATCHING LOCAL CONDITIONS WITH SOLUTIONS THAT CAN BE IMPLEMENTED IN AN EFFICIENT, COST-EFFECTIVE MANNER. RESULTS EXPECTED FROM THIS RESEARCH AND EXTENSION PROJECT WILL INCREASE KNOWLEDGE, AWARENESS, AND UNDERSTANDING OF CROP AND LIVESTOCK INTEGRATED PRODUCTIO SYSTEMS, IMPROVE RESILIENCE FOR CATTLE PORDUCERS GRAZING CORN RESIDUE BY DEVELOPING ADAPTIVE GRAZING MANAGAMENT PRACTICES FOR CORN RESIDUE, AND EXPANDING OPPRTUNITIES FOR GRAZING CORN RESIDUE THAT WILL INCREASE RURAL VITALITY AND LIVLIHOODS.
