Embodiment 1

[0038] 1. The formula of the feed additive is: by mass percentage, 20% of glyceryl monolaurate, 15% of glyceryl dilaurate, 55% of glyceryl monostearate and 10% of carrier (silicon dioxide).

[0039] Juvenile soft-shelled soft-shelled turtles with an initial body weight of (50.23±6.35) g were selected and randomly divided into 2 groups (control group and experimental group), with 20 replicates in each group, and each replication was a breeding pond, and 600 soft-shelled turtles were stocked in each pond. The control group was fed with basal feed, and the experimental group added the above-mentioned feed additives with a mass fraction of 0.5‰ on the basis of basal feed, and the test period was 28 weeks.

[0040] During the experiment, feeding and management were carried out as usual, with free access to water and food, feeding on time every day, and feeding 3 times a day.

Embodiment 2

[0065] 1. Select juvenile soft-shelled soft-shelled soft-shelled turtles with an initial body weight of (50.23±6.35) g, and randomly divide them into 5 groups, with 3 replicates in each group, and each replicate is a breeding pond, and 600 soft-shelled turtles are stocked in each pond. The control group was fed the basic feed, and the experimental groups 1, 2, 3, and 4 added feed additives with a mass fraction of 0.5‰ on the basis of the basic feed. The test period was 29 weeks. The feed additive formulations of experimental groups 1, 2, 3, and 4 are as follows:

[0066] Experimental group 1: in terms of mass percentage, 10% glyceryl monolaurate, 30% glyceryl dilaurate, 50% glyceryl monostearate and 10% carrier (silicon dioxide).

[0067] Experimental group 2: in terms of mass percentage, 30% glyceryl monolaurate, 20% glyceryl dilaurate, 40% glyceryl monostearate and 10% carrier (silicon dioxide).

Abstract

The invention discloses an application of a feed additive to a soft-shelled turtle feed capable of improving meat quality and growing performance of soft-shelled turtles, and belongs to the technicalfield of feed additives. The feed additive comprises 10-45% of glycerol monolaurate, 10-30% of glyceryl dilaurate, 30-55% of glycerol monostearate and 5-15% of a carrier. The glycerol monolaurate, theglyceryl dilaurate, the glycerol monostearate are compounded according to the appropriate content and proportion, so that the feed additive is prepared. The feed additive can be used for trionyx sinensis during growth phase, the growing properties of the trionyx sinensis can be improved, and further, the breeding economic benefits are increased. The feed additive can notably increase the muscle of the trionyx sinensis and the content of crude proteins, the total content of amino acids, the content of necessary amino acids and the content of palatable taste amino acids in turtle edges of the trionyx sinensis can be notably increased, the nutritional quality, the mouth feel and the flavor of the trionyx sinensis are effectively improved, and contradiction between growth rate and quality issolved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the application of feed additives in the preparation of soft-shelled turtle feed for improving the quality of soft-shelled turtle meat and the growth performance of soft-shelled turtles. Background technique [0002] Chinese soft-shelled turtle (Trionyx sinensis), commonly known as soft-shelled turtle, turtle, water fish, etc., is a precious aquatic product loved by the people. It tastes delicious and is a precious raw material for traditional nutrition and health food, with huge economic value. In recent years, the rapid development of Chinese soft-shelled turtle farming has played a positive role in improving people's living standards and earning foreign exchange through exports. However, due to the interests of the Chinese soft-shelled turtle market and the large number of relatives collected by turtle farms, coupled with factors such as the deterioration of the natural...
