Weaned piglet feed and preparation method thereof

Abstract

The invention discloses a weaned piglet feed and a preparation method thereof, and the weaned piglet feed comprises the following raw materials by weight: 45-55 parts of corn; 10 to 20 parts of puffed corn; 8-12 parts of bran; 10 to 15 parts of soybean meal; 6-10 parts of fermented soybean meal; 1-2 parts of soybean oil; 2-6 parts of a premix; wherein the mass ratio of the soybean meal to the fermented soybean meal is (1.5-1.7): 1, the fermented soybean meal contains lactic acid bacteria, saccharomycetes and acetic bacteria, and the total viable count content reaches 200 cfu / g or above. A certain amount of fermented soybean meal is added into the feed, the problem of nutritional diarrhea of the piglets can be solved by reducing the use amount of the soybean meal, and meanwhile growth and development of the piglets are promoted through nutritional components and beneficial bacteria of the fermented soybean meal.

Description

technical field [0001] The present application relates to the technical field of pig feed, more specifically, it relates to a feed for weaned 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. There...

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
