Compound additive for improving intestinal tract health of piglets and preparation method thereof and application thereof

Abstract

The present invention relates to a compound additive for improving the intestinal tract health of piglets and a preparation method thereof and an application thereof, and belongs to the field of feeds. The compound additive comprises chlorella vulgaris powder, L-tryptophan, glutamine dipeptide, enveloped sodium butyrate, ethyl vanillin, white carbon black and a carrier. The selected components ofthe compound additive are all safe and free of harmful residues, and the compound additive can better improve immunity of piglets, improve intestinal health, reduce diarrhea rate and promote healthy growth of the piglets. The preparation method comprises the following steps: firstly, the ethyl vanillin and white carbon black are mixed according to ratios, and then the materials are mixed with thechlorella vulgaris powder, L-tryptophan, glutamine dipeptide, enveloped sodium butyrate and carrier. The method is simple and fast, can fully mix the components, and can enable the compound additive to be stale and lasting in aroma. The compound additive is used for preparing feeds for the piglets, and can obviously improve intestinal immunity of the piglets, repair intestinal mucosa, improve intestinal health, promote nutrient digestion and absorption, reduce diarrhea rate, and thus improve growth performance of the piglets.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a compound additive for improving intestinal health of piglets and its preparation method and application. Background technique [0002] Early weaning technology has been widely used in my country's pig industry. Due to the immature digestive physiological functions of piglets that have just been weaned, when factors such as weaning or food change, piglets often suffer from loss of appetite and weakened digestive function, which leads to intestinal Mucosal damage and intestinal dysfunction lead to reduced digestion and absorption of nutrients and reduced immunity in piglets. Then diarrhea occurs, the feed remuneration decreases, the survival rate of weaned piglets decreases, the growth and development slow down or even stagnate (stiff pigs), what's more leads to the death of piglets, which brings huge economic losses to farmers. [0003] In addition, the homeostatic system for piglets to ...

Then diarrhea occurs, the feed remuneration decreases, the survival rate of weaned piglets decreases, the growth and development slow down or even stagnate (stiff pigs), and what's more leads to the death of piglets, which brings huge economic losses to farmers

[0003] In addition, the homeostasis system for piglets to respond to changes in the external environment is not yet sound, and their own disease resistance is low. They are more sensitive to external stimuli and are vulnerable to the invasion of external pathogenic microorganisms, resulting in death, which also affects the pig industry to a certain extent. development of

[0004] At present, antibiotics are commonly used in production practice to treat problems such as high diarrhea rate and low survival rate of piglets caused by intestinal problems. A series of problems such as residues, which not only pose a threat to the breeding industry, but also affect people's health
