Introduction of soybean phospholipid oil and application of broiler feed
With the rapid growth of the livestock and feed industries, competition in the feed market has become more intense. Soybean phospholipid oil, as an energy source that can replace vegetable oil and lower feed costs, is gaining popularity among manufacturers and aquaculture farmers. Extracted from the byproducts of soybean oil production, this oil contains 1.2%-3.2% phospholipids. It is a complex mixture of esters made from glycerin, fatty acids, choline, or ethanolamine, and is soluble in oils and non-polar solvents. Its composition includes lecithin (about 34.2%), cephalin (about 19.7%), inositol phospholipid (about 16.0%), phosphonate serine (about 15.8%), phosphatidic acid (about 3.6%), and other phospholipids (about 10.7%). These compounds play a vital role in biological functions and are essential for maintaining cell membrane integrity and metabolic processes.
Soybean phospholipid oil typically appears as a dark yellow or reddish-brown viscous liquid. Its general composition includes: soybean oil at 35-40%, lecithin (PC) at 19-21%, cephalin (PE) at 8-21%, phosphatidylinositol (PI) at 20-21%, phosphatidic acid (PA) at 6-11%, other phospholipids at 7-11%, sterols and other compounds at 2-5%, carbohydrates at 5%, and water below 1%. This oil is rich in unsaturated fatty acids, which contribute to its nutritional value and functional properties.
Phospholipids are complex lipids composed of a polyhydric alcohol, fatty acids, and phosphate groups. They often combine with nitrogen-containing compounds like choline, forming important bioactive molecules. In soybeans, when the nitrogen compound is choline, it forms lecithin; if it's ethanolamine, it becomes cephalin. These phospholipids have both hydrophilic and hydrophobic regions, giving them natural emulsifying properties. From a nutritional standpoint, they are essential for cellular function, supporting the structure and function of cell membranes, promoting lipid metabolism, and aiding in the absorption of fat-soluble vitamins.
In broiler feed applications, soybean phospholipid oil offers several benefits. It improves palatability, reduces stress, and enhances weight gain by about 10% when added at 2%-6%. It also helps the body use stored fat more efficiently, increasing energy utilization and reducing abdominal fat accumulation. By replacing animal fats, it minimizes issues related to rancidity and impurities, lowering overall costs. Additionally, it supports protein utilization and reduces the need for methionine and choline. Studies show that adding 2.0%-3.0% phospholipid oil can increase daily weight gain by 7.7%-10.8% and improve survival rates.
When using soybean phospholipid oil as a feed additive, quality standards must be met, such as water content below 22%, acetone insolubles above 45%, and acid value below 5.5. The recommended addition rate for broilers is generally around 2%, depending on the original phospholipid content and other dietary factors.
Proper handling is crucial. Due to its high viscosity, it should be mixed gradually and not added in large amounts at once. In cold weather, it may solidify and should be warmed to 40-50°C before mixing. Because it is prone to oxidation, it is best used shortly after mixing. Antioxidants like 0.1% anti-oxyquine can help reduce the risk of ascites in later stages. Also, while it promotes rapid growth, it may lead to increased mortality due to excessive fat deposition. Adding sodium bicarbonate or multivitamins can help mitigate these effects. Finally, since it increases energy density, other nutrients like calcium, vitamin B12, and amino acids should be adjusted to maintain balanced nutrition.
