Answer:Dairy- This is the one animal food that contains carbohydrate. Milk, cheese, and yogurt contain naturally-occurring lactose. If dairy (like yogurt) is sweetened, then it will also contain added sugar like sucrose (white cane sugar) or fructose and glucose (honey and/or HFCS).
The main source of carbohydrates in livestock feed are grains such as oats, wheat, barley, corn, sorghum etc. forages and hay. Fats are an important part of the animal diet; nevertheless, they are needed in small amounts.
