Embodiment 1

[0025] Example 1 Preparation method of feed additive X1 containing proanthocyanidins and dietary fiber

[0026] Specifically:

[0027] After crushing and sieving, the masson pine bark from Fujian is cleaned and pulverized, and then passed through a 40-mesh sieve. Emulsify and homogenize. Place the crushed and sieved masson pine bark in clean water at room temperature. The material-to-liquid ratio of the crushed masson pine bark to clean water at room temperature is 1g:10mL. Under the condition of a homogenizing pressure of 60MPa, the emulsification is homogeneous After 6 min, the substrate solution is obtained. Ultrasonic-assisted enzymatic hydrolysis, adding a complex enzyme composed of cellulase, pectinase and protease (1:1:1) to the substrate solution after emulsification and homogenization, where the enzyme activity is the enzyme activity of cellulase 0.5U / mg (at 37°C and pH 5.0, the amount of enzyme required to decompose carboxymethyl cellulose to produce 1μmol of glucose in...

[0035] Example 3 Preparation method of feed additive X3 containing proanthocyanidins and dietary fiber

[0036] Specifically:

[0037] After crushing and sieving, the bark of Masson pine from Yunnan is cleaned and pulverized, and passed through a 60 mesh sieve. Emulsify and homogenize. Put the crushed and sieved masson pine bark in clean water at room temperature. The material-to-liquid ratio of the crushed masson pine bark to clean water at room temperature is 1g:12mL. Under the condition of a homogenizing pressure of 100MPa, emulsify and homogenize. After 10 minutes, the substrate solution is obtained. Ultrasonic-assisted enzymatic hydrolysis, adding a complex enzyme composed of cellulase, pectinase and protease (1:1:1) to the substrate solution after emulsification and homogenization, and the enzyme activity of cellulase is 1.2U / mg , The enzymatic activity of pectinase is 3.0U / mg, and the enzymatic activity of protease is 2000U / mg. The ratio of the composite enzyme to the sub...

Abstract

The invention relates to a feed additive containing proanthocyanidins and dietary fiber, a preparation method thereof and a non-antibiotic piglet feed product. The feed additive is prepared by the following method: smashing and sifting pine bark; emulsifying and homogenizing the sifted pine bark to obtain a substrate solution; subjecting the substrate solution to ultrasonic assisted enzymatic leaching by a composite enzyme consisting of cellulase, pectinase and protease; centrifuging the substrate solution after enzymatic hydrolysis to separate an upper layer supernatant and a lower layer precipitate; purifying the supernatant to obtain proanthocyanidins; fermenting the lower layer precipitate to obtain dietary fiber; and mixing and drying the obtained proanthocyanidins and dietary fiber to obtain the feed additive. The non-antibiotic piglet feed product of the present invention contains an appropriate amount of the feed additive. The feed additive of the invention can improve the digestibility of high nutrient substances, and prevent diarrhea of piglets; the non-antibiotic piglet feed has the characteristics of rich nutrients, high absorption, high utilization, and no antibiotics,can significantly improve the antioxidant capacity of the piglets, improve the intestinal tracts, and improve morphology and microbial flora structure to increase the growth performance of the piglets.

Description

Technical field [0001] The invention belongs to the technical field of animal nutrition and feed processing, and particularly relates to a feed additive containing proanthocyanidins and dietary fiber, a preparation method thereof, and a piglet-free feed product. Background technique [0002] The intestine is the main place for the digestion and absorption of nutrients in the animal body, and it is also an effective barrier for the body to resist the invasion of external pathogens. The intestinal health of young animals at the early stage of birth will directly determine the microflora pattern of adult animals. The solution to the reduction or even replacement of antibiotics in animal feeding needs to start with regulating the intestinal health of young animals. [0003] Maintaining a complete intestinal epithelial structure and function is of great significance for improving animal feed conversion rate, promoting animal growth performance, protecting intestinal barrier function, an...
