soybean has higher protein content. The fat content of meats varies with the specie.
Chicken and tilapia have the lowest fat content while beef and lamb have the
highest. Egg and milk products also vary with the specie. Milk from cows and goats
have similar nutritional components while milk from Indian buffalo and sheep tend
to have much higher fat and carbohydrate contents. The values shown in Figure 7.32
for pork, lamb, and beef are for a composite of trimmed retail cuts. The values for
duck, goose, and tilapia are for whole, fresh raw meat. Chicken is represented by
values for raw breast meat of broilers. The values for eggs in Figure 7.33 are for
whole, fresh eggs, and for milk only values for whole, fluid milk are given.

CONCLUSIONS
Farm animals provide food, clothing, and power to humans. In the most direct form, we
consume various parts and products such as meat, eggs, and milk to provide high-quality
protein in our diets. Many animal products provide articles of clothing made from wool
and leather. Farmers use many types of animals to till the soil and carry produce from the
farm to markets. Animals often utilize food materials not directly usable by humans such
as grass or coarse grains, therefore avoiding direct competition for food. Some animal
diseases can be passed to humans and sanitation is essential at all stages of production.
