Embodiment 1
[0031] A preparation method of a liquid feed, the liquid feed is made of the following raw materials in terms of mass fraction: 40% corn (corn for suckling pigs), 15% peeled soybean meal, 10% instant soybean meal, 4% super steam fish meal, plasma protein Powder 5%, whey powder 8%, whole milk powder 6%, glucose 2%, sucrose 4%, lysine 0.5%, calcium hydrogen phosphate 0.8%, fat powder 0.5%, monosodium glutamate 0.2% and premix 4% (Here the premix adopts the premix conventionally added in the feed).
[0032] The preparation method comprises the following steps:
[0033] 1. Grinding: Grinding the large particle raw materials (here, corn and peeled soybean meal) in the feed formula, specifically, using a pulverizer to pulverize, and the pulverizing particle size is controlled at 0.5-1.5mm (here, a diameter of Φ1.0 is used). sieve plate to control particle size).

Abstract
The invention provides a preparation method of a liquid feed. The preparation method comprises the following steps of performing crushing; performing enzymolysis: performing enzymolysis treatment on raw materials needing to be fermented, through high-temperature amylase, so as to obtain feed liquid after enzymolysis; performing fermentation: performing anaerobic fermentation treatment on the feedliquid through lactic acid bacteria, neutral protease and acid protease so as to obtain fermented feed liquid; performing mixing: adding surplus raw materials to the fermented feed liquid so as to obtain mixed feed liquid; and performing acid adjustment: detecting the pH value of the mixed feed liquid, and after the pH value conforms to requirements, obtaining the liquid feed. The liquid feed prepared by the preparation method disclosed by the invention is rich in lactic acid, small peptide, complex enzymes, immunoglobulin and the like, has the characteristics of being balanced in nutrition, good in palatability, high in digestibility and the like, and can effectively alleviate weaning stress syndromes of piglets, so that the growth properties of weaned piglets can be improved, and the mortality rate of the weaned piglets can be reduced. The invention also discloses an application of the liquid feed. The liquid feed is mainly applied to the weaned piglets, so that the growth propertiesof the piglets are better, and the survival rate of the piglets is higher.
Description
technical field [0001] The invention relates to the fields of biotechnology and feed technology, in particular to a preparation method and application of liquid feed. Background technique [0002] In order to improve the production efficiency of sows and the utilization rate of pens, most pig farms now adopt the early weaning production technology of piglets. Weaning stress syndrome in piglets with low food intake, stunted growth, reduced immunity, and high mortality. [0003] In order to prevent diarrhea in weaned piglets, my country currently generally adopts a plan of adding a large amount of antibiotics and high zinc to the feed. Although this method effectively controls the diarrhea of weaned piglets, the feed intake of piglets after weaning is low, growth is hindered, and immunity is reduced. Symptoms are still not effectively resolved. [0004] With the development of scale and intensification of the breeding industry, antibiotic resistance, heavy metal residues an...
