Lysophospholipids (LPL) are very important to the needs of the cells of living organisms, as they are an essential component of the cells as well as their major role in meeting the energy needs of the epithelial cells of the poultry intestine, and the chicks do not achieve maximum benefit from fat due to the lack of bile salts, so adding fat emulsions to the diet is very necessary to fill those Nutritional needs, in ruminants also lysophospholipids improve the production of cows and sheep. Many studies have indicated an improvement in the quality of milk and meat produced from both cows and sheep, as LPL allows ruminants to consume balanced food that meets all nutritional needs and thus stabilizes the rumen environment with fewer fluctuations in the pH value rumen, ammonia concentrate, and rumen fermentation to achieve a high yield, with no or little live weight loss over the lactation period and a low incidence of rumen acidosis. In addition to the great role of LPL in the metabolism of fats, proteins, and minerals, this review will highlight the studies that dealt with the effect of LPL in poultry and ruminants.
