Embodiment 1

[0014] Example 1: Antibacterial performance experiment of trehalose-montmorillonite nanocomposite

[0015] In this experiment, montmorillonite (M), trehalose (T), and trehalose-montmorillonite nanocomposite (TMNC) were tested on the common Gram-negative bacteria Escherichia coli ( Escherichia. coli , strain source: American Type Culture Collection, number: ATCC25922) and Gram-positive bacteria Staphylococcus aureus ( Staphyloccocus aureus , strain source: American Type Culture Collection, No.: ATCC25923) MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) were studied.

[0016] In this experiment, the two-fold dilution method in test tube broth was used.

[0017] The experimental results are shown in the table below.

[0018]

[0019] It can be seen from the above table that montmorillonite has no antibacterial and bactericidal effects on the two bacteria, trehalose has weak antibacterial properties, and trehalose-montmorillonite nanoco...

Abstract

The invention belongs to the technical field of the application of feed additives, and particularly relates to a novel application of a nano compound as a feed additive. The invention provides a novel application of the trehalose-montmorillonite nano compound as the feed additive, and preferably 1 to 2g / kg of the nano compound is added in the feed. The trehalose-montmorillonite nano compound has a positive effect on killing harmful intestinal bacteria, protecting intestinal mucosa and promoting the growth of animals and can substitute the conventional antibiotic-aureomycin of the feed additive. The trehalose-montmorillonite nano compound has the characteristics of safety and environmental friendliness. Through the application of the trehalose-montmorillonite nano compound, the defect that the antibiotics are widely applied in the breeding industry can be effectively overcome, and a safe animal product conforming to the internal standard can be produced.

Description

technical field [0001] The invention belongs to the technical field of feed additive applications, and in particular relates to a new application of a nanocomposite as a feed additive. Background technique [0002] Feed additives refer to small or trace substances added during feed production, processing and use, which are used in small amounts but have significant effects in feed. Feed additive is an inevitable raw material used in the modern feed industry. It has obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost, and improving animal product quality. [0003] Commonly used feed additives include vitamins, amino acids, antibiotics and other substances. As a safe and reliable natural sugar, trehalose is known as the "sugar of life" in the scientific community due to its non-specific protective effect on a variety of biologically active substances, and is widely used in phar...
