Embodiment 1

[0041] The formula of the feed additive is: in terms of mass percentage, 50% of glyceryl monolaurate, 20% of glyceryl dilaurate and 30% of maltodextrin.

[0042] According to the principle of similar body weight and similar genetic basis, 360 90-day-old fattening pigs (half male and female) were selected and randomly divided into 4 groups: control group, test group 1, test group 2 and test group 3, with 3 pigs in each group Repeat, 30 heads per repetition. The control group was fed the basic feed, and the test group 1, the test group 2 and the test group 3 added the above-mentioned feed additives with mass fractions of 0.05%, 0.1%, and 0.2% respectively on the basis of the basic fattening pig feed, and the test period was 60 days.

[0043] The temperature of the feedlot was recorded every day during the experiment. Carry out feeding and management according to the routine, keep the house clean and dry, drink water freely, eat food freely, feed on time every day, feed 3 times ...

Embodiment 2

[0050] The formula of the feed additive is: by weight percentage, 30% of glyceryl monolaurate, 10% of glyceryl dilaurate and 60% of silicon dioxide.

[0051] According to the principle of similar body weight and similar genetic basis, 240 90-day-old fattening pigs (half male and female) were selected and randomly divided into 4 groups: control group, test group 1, test group 2 and test group 3, with 3 pigs in each group Repeat, 20 heads per repetition. The control group was fed the basic feed, and the test group 1, the test group 2 and the test group 3 added the above-mentioned feed additives with mass fractions of 0.05%, 0.1%, and 0.2% respectively on the basis of the basic fattening pig feed, and the test period was 60 days.

Embodiment 3

[0071] The formula of the feed additive is: by weight percentage, 30% of glyceryl monolaurate, 30% of glyceryl dilaurate and 40% of silicon dioxide.

[0072] According to the principle of similar body weight and similar genetic basis, 240 90-day-old fattening pigs (half male and female) were selected and randomly divided into 4 groups: control group, test group 1, test group 2 and test group 3, with 3 pigs in each group Repeat, 20 heads per repetition.

Abstract

The invention discloses application of an additive composition in preparation of swine fattening feed for improving the pork quality or growth performance, and belongs to the technical field of feed additives. The additive composition is prepared from the following components in percentage by mass: 20-50 percent of glyceryl monolaurate, 10-40 percent of dilaurin and 20-60 percent of carrier. By compounding glyceryl monolaurate and dilaurin according to proper content and proportion, the additive composition used in swine fattening phase can be used for improving the growth performance in the fattening phase and increasing cultivation economic benefit. The feed additive can remarkably improve the redness and intramuscular fat of pork and accelerate digestion and absorption of exogenous nutrients, so that the nutritional quality of pork can be improved, and the cooked pork has better flavor. The feed additive guarantees safe and harmless meat product quality, brings safety protection to swine production, and has a great application value.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the application of an additive composition in the preparation of fattening pig feed for improving pork quality or growth performance. Background technique [0002] Fattening is the most important link in the breeding industry, which directly affects the economic benefits of farmers. At present, livestock fattening is realized by optimizing feed formula. The traditional fattening pig feed focuses on fattening time and feed conversion rate, and pays less attention to pork quality. With people's attention to food safety and human health, the requirements for meat products have changed, and it is urgent to market green, safe, nutritious, and flavorful products. Therefore, it is necessary to develop safe, efficient, and green functional ingredients Feed additives are used in the breeding of fattening pigs. [0003] The Chinese invention patent application document with the a...
