Interpretive Summary: Commercial poultry operations use wood chips and/or grain residues as bedding material for the birds. The combination of bedding material and the manure from the chickens is called litter. Chicken litter is typically spread on fields as a fertilizer for crop growth. This study looked at how the nutrient content in grasses of pastures was affected by many years of chicken litter application. Samples of grass from four pastures in Arkansas and Oklahoma were sampled periodically over two years. It was found that most of the time the grass had enough of the major nutrients needed for proper nutrition of pregnant or lactating beef cows. However, there were some times of the year when some minerals were lacking. This research shows that ranchers should provide mineral supplement that contains magnesium and copper to beef cows to make sure that the cows have enough of these key minerals. This research is important to ranchers who fertilize their pastures with chicken litter as it shows that some mineral supplementation is necessary to keep their herds healthy.
