Detailed explanation-1: -Animal and vegetable fats serve as a concentrated energy source and are the highest energy sources in feedstuffs. Fats contain 2.25 times the calories per gram than protein or carbohydrates. Fats contain 9 calories per gram while protein and carbohydrates contain 4 calories per gram.

Detailed explanation-2: -Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates. Because fats are such an efficient form of energy, the body stores any excess energy as fat.
