Fats contain how many times more energy than carbohydrates?

• A. 1.5 times more
• B. 2.25 times more
• C. 3 times more
• D. 2 times more

Answer: (B)

Fats contain approximately 2.25 times more energy than carbohydrates. This is due to the chemical structure and composition of fats compared to carbohydrates. Fats, or lipids, are composed of long chains of carbon and hydrogen atoms and provide about 9 calories per gram, while carbohydrates provide about 4 calories per gram. The higher number of bonds in fats means they can store more energy, which is why they are a dense source of energy for the body. This energy density is crucial for animals, including swine, as it allows for efficient energy storage and utilization. Understanding the energy content of these macronutrients helps in formulating diets that meet the energy needs of swine for growth, reproduction, and overall health.
