Energy is one of the most important factors in animal nutrition and feed fats are often added for this purpose. However, young chickens and piglets cannot always deal with high amounts of fats in their diet. Adding biological emulsifiers, cal led phospholipids, might be the solution, says Yuyun Mu.
Conclusion
Dietary supplementation of PLs has proven to be effective in improving fat digestion and nutrient utilisation, and consequently in improving growth performance, particularly in broilers and weaning piglets. Discrepancy in the responses of animals to added PLs is most likely attributed to differences in ages of animals, dietary fat type and level, compositions and levels of added PLs, dietary compositions and nutrient levels. PLs are recommended to be supplemented into feeds for young piglets and chicks, containing a higher level of feed fats/oils, as well as a higher level of saturated fats.
