Objectives of this project are to determine how animal performance, metabolism, digestibility, and wool and carcass characteristics of growing lambs and kids are affected by replacing protein (cottonseed meal) and energy (milo) feeds with DDG. Trials 1 and 2 (Period 1; Spring and Summer, 2008) will evaluate use of DDG on lamb and kid performance and wool and carcass characteristics. Trials 3 and 4 (Period 2; Fall, 2008) will evaluate the use of DDG on feed digestibility and nutrient metabolism in small ruminants.
Results from these trials will assist nutritionists in establishing a level of DDG that can be safely and efficiently fed to lambs and goats in growing rations. This knowledge should greatly increase the use of DDG since this study will quantifying positive and negative affects associated with feeding DDG, which are high in phosphorus, sulfur, and fat. If DDG can effectively replace a portion of a protein or energy feed source, then it will become a more viable feed alternative when formulating feed rations. We believe that DDG will enhance animal performance in this study, which will increase utilization and value of this by-product.
