Poster Abstract Bartlett, J. R., E. G. Rhoden,
and V. A. Khan. 2009. Feeding value of wheat and sorghum-sudangrass fertilized
with poultry litter. JEMREST 6b:00-00 Poultry litter (PL) can be used as a low cost fertilizer. It returns nutrients and organic matter to the soil, and builds soil fertility and quality. Poultry litter has been shown to improve the quality of forages as well as increase yields. Reports indicate an increase in protein content of forages compared to commercial fertilizers. A study was conducted to evaluate the production of winter wheat (WW) and sorghum-sudangrass (SSG) using different levels of poultry litter application. Treatments were 0, 2 and 4 tons/acre poultry litter incorporated into the soil. Winter wheat was planted during the fall and harvested in the spring. After WW was harvested, SSG was planted in the same field without further PL application. Sorghum x sudangrass was harvested in the summer. Samples of both forages were analyzed for quality and mineral content. Results showed that PL supplied nutrients produced high quality hay for both forages. Crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) were highest for WW and SSG at 4 tons/acre, while total digestible nutrients (TDN) were highest in the control. There were no significant differences in mineral content (calcium, phosphorus, potassium and magnesium) for both WW and SSG. Overall, results indicated that the application of PL at 2 or 4 tons/acre sustained high production of WW and SSG forages with elevated levels of nutrients that would support animal growth.
