The resulting treatment ration contained 2% more NDF and 2% less NFC (of the ration dry matter). Small changes can produce big results! During the first period of the test, cows on the treatment diet produced milk with 0.5% higher fat test (3.5 more pounds of 4% Fat Corrected Milk per day), a statistically significant effect. After 2 months, the treatment and control groups were switched. The effect of switching diet was pronounced. Removing NutriFiber silage from their ration reduced fat test by 0.35%. Adding NutriFiber silage increased fat test by 0.35%. A clear demonstration of the value of NutriFiber!
