[0038] The invention provides a preparation method of acidified calcium salt fermented feed for livestock and poultry, which comprises the following steps: mixing calcium source and citric acid concentrate to obtain acidified calcium salt fermented feed for livestock and poultry.
[0039] In the present invention, the calcium source is calcium lactate and / or calcium citrate; in the present invention, the preparation method of the citric acid concentrate comprises: pulverizing starch-containing products or beating sugar-containing products to obtain enzymatic hydrolysis raw materials ; Mix the enzymatic hydrolysis raw material with water to prepare slurry, add amylase to enzymatic hydrolysis, liquefaction and saccharification to obtain saccharification liquid with slag; add citric acid-producing bacteria to the saccharification liquid with slag and ferment for 62-70 hours at 29-31°C Afterwards, centrifuge or filter the fermented liquid, collect the liquid phase component as citr...

[0055] A preparation method of acidified calcium salt fermented feed for livestock and poultry, comprising the following steps:
[0056] Crush 150kg of broken rice, add 1050kg of water to make slurry, add 0.18kg of liquefying enzyme and glucoamylase to enzymatically hydrolyze, liquefy and saccharify when the temperature rises to 95°C, and obtain 40kg of sugar slag wet base and 1157kg of slag-free saccharification liquid after solid-liquid separation; no slag After high-temperature sterilization and cooling of the saccharified liquid, 20 kg of lactic acid-producing bacteria seed liquid was added, and calcium hydroxide solution was added to control pH 6.0 at 49 ° C. After anaerobic fermentation for 55 hours, 1245 kg of calcium lactate fermentation liquid containing bacteria and lactic acid was obtained.
[0057] After heating 1245kg of calcium lactate fermentation liquid containing bacteria and lactic acid to 80°C, use solid-liquid separation equipment to separate the solid-liqui...

[0062] A preparation method of acidified calcium salt fermented feed for livestock and poultry, comprising the following steps:
[0063] Grind 150kg of corn, add 1050kg of water to make slurry, add 0.16kg of liquefying enzyme and glucoamylase to enzymatically hydrolyze, liquefy and saccharify when the temperature rises to 95°C, and obtain 120kg of sugar residue wet base and 1080kg of residue-free saccharification liquid after solid-liquid separation; residue-free saccharification Add 50kg of lactic acid-producing bacteria seed liquid after liquid high-temperature sterilization and cooling, flow calcium hydroxide solution to control pH5.9 at 48°C, and after anaerobic fermentation for 55 hours, 1120kg of calcium lactate fermentation liquid containing bacterium and lactic acid was obtained.
[0064] After heating 1120kg of calcium lactate fermentation broth containing bacteria and lactic acid to 80°C, use solid-liquid separation equipment to separate the solid-liquid of the calciu...
