We all know that soybean phospholipid oil powder can improve the growth efficiency and feed conversion rate, so you know why, here are experts at home and abroad to answer this question through experiments.
1. Studies at home and abroad show that piglets' emulsifying ability to fat is weak due to the lack of bile secretion within 14 days after weaning. Adding soybean phospholipid oil powder to piglet feed can improve the digestibility of crude protein and energy, reduce diarrhea caused by dyspepsia, promote metabolism, improve weight gain and feed conversion rate. Gunther (1994) showed that the daily gain of piglets increased by 9.5% and the feed to weight ratio decreased by 7.5% when 0.2% soybean phospholipid oil powder was added to the diets of weaned piglets, and the daily gain increased by 17.1% and the feed to weight ratio decreased by 12% when 0.6% was added. The experiment of glycidylcholine (2000) on Weaned Piglets showed that the daily gain of piglets increased by 6.8% and the feed saved by 5.4%. Adding it to the growing pig diet has the same effect. Li Li (1999) showed that the daily gain of growing pigs increased by 7% when 5% soybean phospholipid oil was added to the diet.
2. It has been confirmed that the addition of soybean phospholipid oil powder can significantly improve the digestibility of non milk fat in artificial milk. The average daily gain of the experimental group was 870-880 g / D in 5 months, which was 53% - 64% higher than that of the control group. At the same time, adding soybean phospholipid oil powder and fat to the feed can solve the problems of metabolic disorder and growth retardation when the calves are fed with synthetic diets of casein, lactose, minerals and vitamins.
3。 It has been reported that adding soybean phospholipid oil powder to broiler feed can improve the growth of broiler, increase the storage of vitamin A in liver and promote the growth of bone。 The experiment of Geng Qinghui (1996) showed that adding 2% modified soybean phospholipid oil powder to broiler diet could increase the weight gain by 7% ~ 10% and feed return by 5% ~ 8%; feeding feed containing 1。5% soybean phospholipid oil powder to laying hens could increase the egg production rate by 9。9% and feed return by 9。2%。 Chang Kai Cheng (1998) used concentrated soybean phospholipid oil powder to replace 3% of the oil in the diet of laying hens。 Adding soybean phospholipid oil powder to the diet of laying hens increased egg production by 7。1% and reduced protein consumption by 7。2%。
4。 In the rapid growth of aquatic fish after hatching, abundant soybean phospholipid oil powder is needed to form cell components。 When the biosynthesis of soybean phospholipid oil powder can not fully meet the needs of larvae, soybean phospholipid oil powder needs to be added to feed。 In addition, the soybean phospholipid oil powder in the feed can promote the utilization of cholesterol by crustaceans and improve the growth and survival rate of crustaceans。 The demand of soybean phospholipid oil powder is different in different growth period of shrimp。 Because young shrimp can not synthesize enough soybean phospholipid oil powder for growth and metabolism, the demand of young shrimp for soybean phospholipid oil powder is high。 Abramo et al。 (1981) showed that lobster needs egg soybean phospholipid oil powder to ensure its survival during shelling。 Japanese scientists pointed out that the diet containing 0。5% - 1% soybean phospholipid oil powder is necessary for the growth and survival of juvenile shrimp。 Xue Yongrui et al。 (1989) showed that adding 2% modified soybean phospholipid oil powder to carp feed increased 30。7% compared with the control group, reduced feed coefficient by 0。21 and feed cost by 9。63%。 Poston (1990) added 4% or 8% soybean phospholipid oil powder to the feed, which significantly reduced the feed coefficient of Atlantic salmon。 Kanagana et al。 (1985) reported that adding 1% soybean phospholipid oil powder to shrimp feed can improve the growth rate and survival rate of shrimp。
Although soybean phospholipid oil powder has many advantages, it should be used to determine the appropriate amount of phospholipid according to the amount of phospholipid originally contained in the feed, the size of animals, the content of fat and saturated fatty acid in the feed, the cost of the feed, the type and concentration of phospholipid.
