Document Summary
Macronutrients and micronutrients are usually given to animals via supplementation rather than in their feed. Microbes in the rumen can create protein from non-protein nitrogen such as urea. There are three general classifications of feedstuffs: energy: generally high in carbohydrates and fats, protein: high in amino acids, protein, and non-protein nitrogen, roughage: high in fiber and bulk. Good for the health of the gi tract. Silage and haylage (fermented and high in moisture) Silage contains more moisture than haylage and is made from grain crops. Functional feeds are those which have physiological benefits in addition to those that are provided by nutrient function. Vitamin c and vitamin e have antioxidant activities. Green tea has been shown to reduce cholesterol. Functional feeds help reduce the antibiotic load going into the food chain. Low folate levels can cause spina bifida in babies. This is not a concern for ruminants because the microbes in the rumen produce it along with other b vitamins.
