Liquid state composite microecological preparation for pigling and preparation method thereof

Abstract

The invention provides a liquid state composite microecological preparation for pigling and a preparation method thereof. Per milliliter of the liquid state composite microecological preparation contains lactic acid bacteria, whose live bacteria number is equal to or more than 2x107CFU, 30-60mg of Chitosan oligosaccharide, 0-60mg of vitamin C, 0-45mg of sodium butyrate and 0-60mg of L-glutamine. The preparation method comprises the followings steps: a MRS medium is used for cultivating lactic acid bacteria till the content of the target live bacteria is higher than or equal to 2x109CFU/ml, vitamin C, sodium butyrate, L-glutamine and Chitosan oligosaccharide are dissolved in a the microecological preparation liquid of the medium according to formula amount, a uniform mixing is carried out, and the composite microecological preparation liquid is obtained. According to characteristics of pigling intestinal flora growth and sucking pig breeding management, Chitosan oligosaccharide is used for enhancing stability of the microecological preparation, especially the stability of lactic acid bacteria, and a high efficiency liquid state composite microecological preparation is developed.

Description

technical field [0001] The invention belongs to the field of functional additives for pig breeding, and in particular relates to a liquid composite microecological preparation for piglets and a preparation method thereof. Background technique [0002] The intestinal flora of piglets is unstable and prone to change within 2 weeks after birth. Bacilli and enteric streptococci first appear in the colon, followed by bifidobacteria and become the dominant bacteria. Influenced by anaerobic bacteria, mainly bifidobacteria; during the weaning period, the intestinal flora is very unstable, the lactobacillus linearly decreases, and the Escherichia coli linearly increases; two weeks after weaning, the intestinal flora is stable, and the Predominantly obligate anaerobes. According to the above-mentioned characteristics of intestinal flora development of piglets, the intestinal flora system from birth to 2 weeks after weaning is extremely imperfect, and the imbalance of intestinal flo...

Problems solved by technology

[0005] The above patents are all solid products, and the Lactobacillus in solid form is in a dormant state and is easy to survive

However, for newborn piglets that do not eat solid feed, supplementary feeding is difficult; at the same time, there is a wide range of supplementary doses, and when piglets suffer from disease, feed intake decreases, and adding feed ratios may make piglets unable to eat to a sufficient dose
