Question 7 (3 points) ? Listen Which of the following statements about fiber is incorrect? Humans cannot extract energy from fiber. Fibrin the diet slows the passage of food through the intestines. Fiberscrapes the wall of the digestive tract, stimulating mucus secretion and aiding in the digestion of other molecules. The cellulose in celery stalks and lettuce leaves is a type of fiber. Dietary fiber reduces the risk of colon cancer.

Step 1
While humans cannot digest fiber like they do with other nutrients, some types of fiber can be fermented by bacteria in the gut to produce short-chain fatty acids, which can provide some energy to the body. Show more…

Select the FALSE statements below about feeding carbohydrates: Select 4 correct answer(s) Vegetables and cereals are low lignin, grasses intermediate and legumes higher. Easily digestible carbohydrates can be added to the diet quickly without any digestion problems. To much fat in a ruminant diet can bind fiber and increase cellulose digestion. Late pregnant animals, especially those with multiple fetuses or that are overly fat, may get ketosis from lack of energy in the diet. Lactating animals have higher energy needs than non-lactating. Disaccharides can be readily absorbed by the gut of any age animal. The 'scratch factor' concept says that long stemmed fiber can stimulate digestion and movement of the rumen so older non-ruminant animals are more feed efficient.
