Fermented liquid suckling pig feed and preparation method thereof

Abstract

The present invention discloses a fermented liquid suckling pig feed and a preparation method thereof. The preparation method comprises the following steps: conducting expanding culture of yeast and lactic acid bacteria respectively to obtain the seed yeast solution and the seed lactic acid bacteria solution; smashing the plant raw materials, and then adding the seed yeast solution, seed lactic acid bacteria solution and water into the smashed materials to conduct a mixed fermentation and obtain a liquid mixed fermentation product; firstly smashing the non-fermented raw materials, then adding the smashed non-fermented raw materials into the liquid mixed fermentation product, and mixing evenly to obtain the suckling pig feed. The fermented liquid suckling pig feed does not add any antibiotics, is rich in glucose, lactic acid, small peptides, yeast culture product, amino acids, vitamins and minerals, and has the characteristics of having balanced nutrition, good palatability, easy digestion, good absorption and low anti-nutritional factors. The suckling pig feed can enable the suckling pig to have a smooth transition from being fed by breast milk to being fed by liquid feed, thus achieving the effect of reducing the suckling pig diarrhea rate and improving the suckling pig survival rate.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a fermented liquid suckling pig feed and a preparation method thereof. Background technique [0002] Piglets face the challenge of "weaning stress syndrome" during the weaning period. Controlling pathogenic bacteria and improving feed digestibility are important management techniques to prevent diarrhea. For a long time, even at this stage, people are used to adding antibiotics, high copper, and high zinc to feed to control diarrhea. However, with the large-scale and intensive development of the aquaculture industry, the problems of antibiotic resistance, heavy metal residues and environmental pollution have attracted more and more attention. Today, when food safety is of great concern, many countries have banned the use of antibiotics in feed. [0003] Most of the feeds for suckling pigs on the market are powder or pellets, and there are more or less the following problems in th...

AI Technical Summary

Problems solved by technology

[0003] Most of the feeds for suckling pigs on the market are powder or pellets, and there are more or less the following problems in the application process: First, the gap between solid feed and breast milk is large, not only the effect of teaching the trough is poor, but also the piglets do not adapt to it after weaning. , resulting in low feed intake, insufficient nutrient intake, and high mortality; second, in order to prevent diarrhea, solid feed is usually added with antibiotics, which is not conducive to the health and growth of piglets, and does not meet the requirements of national safe and healthy breeding

Third, solid pellet feed has to go through processes such as crushing, puffing, and granulation, which destroys a lot of nutrients and consumes a lot of energy, which does not meet the national energy conservation requirements.
