[0018] Example 1
[0019] The present invention uses microecological fermentation technology to process food processing leftovers into enzyme preparations, and uses liquid enzyme preparations to add dry matter to make proteases as feed additives. The method for feeding livestock and poultry to prevent environmental pollution includes the following steps:
[0020] 1. Crush the leftovers of food processing bread and pastry into a paste, then put it into the Bacillus natto fermentation tank to deep ferment to make a cow mouth-like liquid enzyme preparation, and use the feed hygiene index to detect the standard after use.
[0021] 2. Add soybean meal to enzyme preparation at a ratio of 1:1, ferment at 38°C for 48 hours, and dry the powder at a low temperature below 50°C into 60 mesh powder. Test the total number of bacteria, crude protein content, enzyme activity, total number of bacteria, Heavy metal arsenic mg / kg (calculated as As) <5.0, lead mg / kg (calculated as Pb) ≤ 10.0, cadmium mg...
Example Embodiment
[0022] Example 2
[0023] The method of the present invention for processing the leftovers of processed meat products into proteases as feed additives to feed livestock and poultry to prevent and control environmental pollution includes the following steps:
[0024] The leftovers, bones, minced meat, and expired food in the meat processing process are cooked and broken into 20 meshes, and then loaded into the fermentation tank with Lactobacillus acidophilus for deep fermentation. After passing the national feed standard test, the solid-liquid separation, and the liquid is added Wheat bran, adjust humidity at 50%-60%, anaerobic fermentation at 38℃ for 48 hours, then add wheat bran according to 1:1, dry at low temperature below 50℃, crush into 60 mesh powder, package for use after protease testing is qualified.
Example Embodiment
[0025] Example 3
[0026] The present invention processes leftovers, fruit peels, vegetable leaves and other organic matter in the fruit processing process into proteases as feed additives. The method for feeding livestock and poultry to prevent environmental pollution includes the following steps:
[0027] The leftovers from the fruit processing process, the fruit, peel, vegetable leaves and other organic matter are crushed and put into the fermentation tank with Enterococcus faecium for deep fermentation. When the test is qualified, use the liquid that becomes cow mouth water-like drawing 1:1 to add wheat bran and stir. Uniform anaerobic fermentation at 38°C for 48 hours, mix well with the fermented wheat bran at a ratio of 1:1, dry at a temperature below 50°C, smash into 60 mesh powdered protease, and pack it for later use after passing the test, which can be used as garbage A series of products, such as flavour agent, waste degrading powder, food waste starter, lactic acid bact...
