Abstract
The invention discloses a compound emulsifier for animal feeds, which is prepared by the raw materials based on the parts by weight as follows: 20-25 parts of sugar esters (SE)-5, 40-60 parts of SE-13 and 20-30 parts of monoglyceride. The emulsifier of the invention has good emulsifying effect and low production cost; in addition, the raw materials are solid powder in the physical form, are free of toxicity and peculiar odors and are convenient to add. The emulsifier of the invention is added into the daily rations of animals for feeding and metabolism tests. In the broiler feeding test, the average daily gain of the broilers is increased by 7.0%, the feed to gain ratio is decreased by 4.44%, the utilization ratio of the crude fat is increased by 1.81% and the utilization ratio of the crude protein is increased by 5.8%. Compared with the feeds using compound agents of single emulsifiers in the prior art, the feeds in the invention enjoys that the production properties and the nutrient utilization ratios are improved to different degrees.
Description
technical field [0001] The invention relates to an emulsifier, in particular to a compound emulsifier for livestock and poultry feed. Background technique [0002] In modern animal husbandry that pursues breeding efficiency, oil, as a high-calorie energy source, has become more and more common in feed. However, the effect of adding oil is often unsatisfactory. Young meat livestock and poultry, various digestive organs are not fully developed, so the digestion and absorption rate of fat is limited, resulting in a huge waste of high-energy feed, increasing the cost of breeding, and increasing environmental pollution. Therefore, it is inevitable to add exogenous emulsifiers that can promote fat digestion and absorption in feed. [0003] At present, soybean lecithin is the most exogenous emulsifier added in feed. The research on emulsifiers that has been carried out has focused on phospholipids and cholate, but the emulsification effect of phospholipids is limited, and the cos...
