Problems solved by technology

[0003] Traditionally used antibiotics are about to be banned due to unfavorable factors such as drug resistance residues, so seeking alternatives to antibiotics is a hot topic in pig farming
Studies have reported that prebiotics, organic acids, probiotics, oligosaccharides, high copper and high zinc, etc. can alleviate a series of problems such as growth retardation caused by weaning stress, but these methods have high costs, immature technologies, Problems such as unstable effects

preparation example 1

[0064] A preparation method of plant extract, comprising the following steps:

[0065] Mix and pulverize 30kg of Pulsatilla pulsatillae, 15kg of honeysuckle, 8kg of licorice, 5kg of black plum and 10kg of Cortex Phellodendri, and sieve to obtain a plant powder with a particle size of ≤75 μm;

[0066] Put the plant powder into a sealed tank, pass in water vapor, and keep it at a pressure of 2 MPa and a temperature of 150°C for 5 minutes;

[0067] Put the autoclaved plant powder in a 75% ethanol solution for ultrasonic extraction, the ultrasonic power is 90W, the temperature is 40°C, and the extraction is 30min;

[0068] After extraction, the plant extract is obtained by membrane filtration and spray drying.

Abstract

The invention discloses a piglet plant feed and a preparation method thereof, and the piglet plant feed comprises the following raw materials in parts by weight: 45-55 parts of corn, 10-20 parts of puffed corn, 10-20 parts of soybean meal, 6-15 parts of fermented soybean meal, 1-2 parts of soybean oil, 2-6 parts of a premix and 2-6 parts of a plant additive. The preparation method comprises the following steps: S1, crushing and mixing corn, puffed corn, soybean meal, fermented soybean meal, soybean oil, a premix and a plant additive in proportion to obtain a mixture; s2, granulating, cooling and screening the mixture to obtain a finished product. The plant additive composed of the bacillus coagulans and the plant extract is added into the feed, so that the rewriting rate of the piglets can be reduced, and the growth speed of the piglets can be increased.

Description

technical field [0001] The present application relates to the technical field of pig feed, more specifically, it relates to a plant feed for piglets and a preparation method thereof. Background technique [0002] In the process of modern pig production, the best weaning time for piglets should be 25 to 30 days old. Among them, weaning will cause nutritional, environmental and psychological stress in piglets, resulting in decreased appetite, reduced feed intake, and affected growth and development. , weight loss, diarrhea, and eventually death. Since the digestive tract and enzymes of piglets are not yet fully developed, there is less gastric acid secretion and low enzyme activity. When piglets are weaned, they have not adapted to the antigenic substance or the intestinal tract has not yet established immune tolerance, which will induce diarrhea. [0003] Traditionally used antibiotics are about to be banned due to unfavorable factors such as drug-resistant residues. Theref...
