- Chicken fat is a quality source of essential fatty acids and an excellent source of energy. Fat has a positive effect on the immune system and plays a beneficial role in stress response. Essential fatty acids are required for proper growth, reproduction, normal skin structure and a healthy coat. Because chicken fat contains virtually no protein, it's use does not cause allergic reactions associated with the use of fresh chicken or chicken meal which contain high amounts of protein.
