Suddenly on our September test MUN dropped to less than 9. What factors could contribute to this? ANSWER: Fall feeding and new crops being made make this a very common scenario. Most pro ducers that test MUN monthly see the correlation between constant MUN values and their success in maintaining a constant diet fed to their cows. There ate a few things that can happen within the cow’s diet that Fire Hall. Hunlsdale 7pm 7 pm can soil the plan. One is so simple that we often overlook it Moisture changes within the forage part of the diet can change mote than the dry matter intake. Make sure diets get adjusted for this change but also consider this thought: typical Pennsylvania forage is some sort of hay crop silage. There is tremendous variation in moisture levels as hay crop is ensiled in trenches, tower silos, bags, and wraps. Typical protein tests can be vety similar regardless moisture but often the soluble or dcgrable pro tein changes with moisture content Moisture levels lower than 50 percent and those higher than 60 percent, even though crude protein remains the same, can be quite dif ferent in what rumen bugs have available to them. As a rule of thumb, when mois ture levels decrease the soluble or degradable protions also decrease. Veiy wet forages also show higher soluble or degradable portions. The farm was advised to look at changes in this part of the diet and indeed haylage has dropped from 65 percent 50 percent moisture as feed from their bunk. Soluble pro tein levels on the wetter feed were 64 percent and on the drier feed, 56 percent. This change resulted in less available protein for use by rumen bugs, less milk produced, and MUN values were drastically reduced. Sometimes changes occur in our cows and we can only react to them. This dietary change was not planned but nevertheless had a large impact on the cows. We can use this to build a plan for the MANHEIM ARTHUR AUKER • 717-665-6627 RICHFIELD SAMUEL KNOUSE • 717-463-2885 SALEM DONALD EMEL* 609-769-1577 THOMPSONTOWN ROGER SANER • 717-535-5307 WYALUSING ANDY CAMPBELL • 717-363-2133 Lancaster Farming, Saturday, November 7, 1998-A2] Number one yield performer in the 109-113 day range.

America’s down to earth seed company future that allows us to anticipate performance changes that arc trig gered by feed changes. Simply put, if I had haylage that remains top quality, but changes occur in the protein fractions and moisture content, I would do what is necessary to head off perfor mance changes in the cows. MUN in this instance not only gave us a diagnostic tool for today’s production, but we have found that by knowing what drives MUN in the diet can help us ward off potential negative trends in production. Don’t be satisfied with accept able MUN values but instead use constant testing and relate MUN with diet changes. By doing so, I bcleivc the 4-pound loss on 260 cows for an undetermined length of time could be avoided. Isn’t the risk of losing $l5O dai ly worth testing for and learning to use MUN? I think it is. Use the tools available along with your farm advisors, to help avoid a potential loss. Better yet, develop an aggres sive attitude toward DHIA records and force yourself to act and not just react.
