Document Summary

Glucose is the primary subunit in most carbohydrates. Glucose is the primary building block in most plants. Comprise up to 70% of the dry matter of forages, as much as 80% in grains. Dry matter basis assumes no water is present - 100% dry matter. Because nutrients are found in the dry matter portion of feeds, the quantity of nutrients will not change when water is added or removed. However, the percentage of nutrient present in the feed will change if water is added or removed. Animals can get calories from carbs and from fats and from proteins. Carbs are plentiful and cheap in the us. So carbs (rather than fats and proteins) are included in animal diets as a source of energy. In fact carbs are the most abundant nutrient in many animal diets. Composed of carbon (c), hydrogen (h), and oxygen (o) Found in such plants as sugar cane and sugar beets.
