Problems solved by technology

At present, soybean lecithin is the main exogenous emulsifier added in feed. The research on emulsifier mainly includes phospholipid and cholate. In addition, there are Tween and Span series products on the market, but the emulsification effect on feed fat is not good. not ideal

Embodiment 1

[0048] Polyglyceryl fatty acid ester 65%, sodium stearyl-2-lactate 15%, sodium saccharin 1.5%, sodium glutamate 1.5%, L-carnitine 1.5%, rice husk powder 0.5% and zeolite powder 15%. The above-mentioned components were weighed and placed in a small horizontal double-shaft paddle stainless steel mixer for 10 minutes to obtain a composite emulsifier.

[0049] To confirm the emulsifying power of the composite emulsifier in Example 1, add 0.1 g of the composite emulsifier to the oil-water mixture (soybean oil: water = 3: 7), homogenize and stir, and observe at room temperature and heat treatment respectively emulsifying power. Under the same conditions, a single emulsifier, sodium stearyl-2-lactate and polyglycerol fatty acid ester were added for homogenization and stirring as a control group.

Abstract

The invention provides a composite emulsifier for animal feed, a use method and application, and belongs to the technical field of emulsifiers. The composite emulsifier is prepared from the followingcomponents in parts by mass: 65 to 70 parts of polyglycerol fatty acid ester, 15 to 20 parts of stearyl-2-sodium lactate, 1.5 to 2.5 parts of a sweetener, 1.5 to 2.5 parts of a flavour enhancer, 1.5 to 2.5 parts of L-carnitine, 0.5 to 1.5 parts of an organic carrier, and 1 to 15 parts of an inorganic carrier. The comosite emulsifier has a stronger emulsifying power to improve piglet growth performance with daily gain increased by 18.42% to 23.68%, daily feed intake increased by 10.52% to 13.16%, feed conversion rate increased by 7.84% to 9.31%, the apparent digestibility of crude fat increasedby 24.19% to 25.53%, the apparent digestibility of crude protein increased by 5.83% to 8.96%, and the apparent digestibility of energy increased by 4.18% to 4.86%.

Description

technical field [0001] The invention belongs to the technical field of emulsifiers, and in particular relates to a compound emulsifier for animal feed, its use method and application. Background technique [0002] The improvement of livestock and poultry productivity and number of herds is achieved through the improvement of breeding technology, management methods and livestock house environment, and the reasonable combination of feed nutrition plays a more important role in it, improving the digestibility of livestock and poultry nutrients and The conversion rate of feed can not only save the feeding cycle and reduce the cost of feed, but also avoid the problem that livestock and poultry cannot fully absorb the nutrients in the feed, and reduce the pollution of manure to the environment. [0003] Pork and pork products are indispensable food on people's table, which directly promotes the rapid development of pig industry. In the whole process of pig raising, the feed and f...
