Researchers at the University of Kentucky review research that shows young heifers exposed to more hours of light were more feed-efficient; had increased lean-tissue growth; and produced more milk early in their first lactations.
Farm magazines are buzzing with news about reduced lignin alfalfa varieties. Alforex Seeds is marketing two Hi-Gest® varieties for 2015 (one with a fall dormancy rating of 3 which is suitable for Northern regions) and Monsanto planning the sale of HarvXtra™, a glyphosate-resistant alfalfa, for 2016. Where does this new technology fit on your farm? That will depend on how you intend on using reduced lignin alfalfa, and also whether you seed a forage grass with alfalfa.

Good forage crops place a high demand for potassium on the soil’s nutrient supplying power. Potassium is critical for growing high yield, high quality alfalfa, helping maximize animal performance and profitability.
