Excellent discussion and education related to Beef Nutrition.  This is the first of a two part series were we talk about protein and energy needs of cows and heifers during different times of year and reproduction.  We also discussed knowing your hay.  This discussion included hay testing, understanding test results, sampling, important results to make decisions on supplementation, examples of hay tested after the recent wildfires, testing variations and types of hay, risk avoidance from prussic acid and nitrates in certain hay, and frost/drought issues that might impact these risk factors.  Dr. Jason Smith, Extension Beef Cattle Specialist with Texas A&M AgriLife Extension led the discussion and provided outstanding information.   We will be following this program up with the second program focused on decisions on supplementation and feed sources available.  This should be a great followup to this program.
