As the intensive animal production industry requires the animal to grow fast and efficiently. They have to grow as fast as possible with the minimize amount of feed. So, they need the rich energy's diets for consumption, which is usually supplied by the addition of fats and oils.
By the way, before these fats can be digested, the emulsification by emulsifying agents such as bile acids is needed. This process is necessary because of the digestive tract is an aqueous environment, although fats and oils are lipophilic substances.
In the first stage of fat digestion, fat have to emulsified by bile salts and phospholipids. Because of the fat is insoluble in water, the fat droplets will accumulate into the fat globules in the aqueous environment of the small intestine. To avoid this, fat emulsification by bile salt is needed due to emulsified the large lipid globules into the small lipid droplets.
The reducing in fat globule size is the result in increase the contact surface with lipase for hydrolysis. The fat molecule, Triglyceride, is broken down by lipase into 2 fatty acids and 1 monoglyceride.
After fat hydrolysis, fatty acids and monoglyceride have to mixed with the bile salts and other phospholipids to form the micelle for transport the lipophilic substances in the intestinal lumen and through the unstirred water layer of the enterocytes for nutrient absorption.
However, the young animal cannot produce sufficient amounts of bile acids for efficient emulsification and micelle formation. So, the supplementation of emulsifying agents such as Lysolecithin can be beneficial for nutrient digestion and absorption of young animals.
