A low -protein biological feed and its preparation method
A biological feed, low-protein technology, applied in the direction of animal feed, animal feed, additional food elements, etc., can solve the problem that animal feed cannot meet the requirements of pig growth performance and low protein content at the same time, so as to reduce the level of feed protein and reduce the protein content. Beneficial to health and the effect of reducing urine output

Embodiment 1
[0088] The low-protein biological feed described in this embodiment is more suitable for pigs in the growth stage. Its formula is as follows: 75.58 kg of corn, 15.5 kg of soybean meal, 3.8 kg of bran, 1 kg of soybean oil, 0.55 kg of stone powder, and 1 kg of calcium hydrogen phosphate , salt 0.4kg, premix 0.6kg, compound probiotics 1kg, L-lysine 0.35kg, DL-methionine 0.08kg, L-tryptophan 0.04kg, L-threonine 0.1kg; The weight ratio of butyric acid bacteria, lactobacillus fermentum and bacillus subtilis in the probiotics is 2*10 3 :1:10.
[0089] Among them, the premix suitable for the diet of pigs in the growth stage contains vitamin A, 5,512IU, vitamin D per 1kg diet 3 , 2,200IU, vitamin E, 64IU, vitamin K 3 , 2.2mg, vitamin B 12 , 27.6 μg, vitamin B 2 , 5.5mg, vitamin B 5 , 13.8mg, Niacin, 30.3mg, Choline Chloride, 551mg, Manganese, 100mg, Iron, 100mg, Zinc, 100mg, Copper, 150mg, Iodine, 0.3mg, Cesium, 0.3mg.
[0090] Take the above-mentioned raw materials and mix them ...
Embodiment 2
[0092] The low-protein biological feed described in this embodiment is more suitable for the ration of pigs in the fattening stage, and its formula is as follows: 7 kg of corn, 10 kg of soybean meal, 8 kg of bran, 0 kg of soybean oil, 0.55 kg of stone powder, 0.85 kg of calcium hydrogen phosphate, and salt 0.4kg, premix 0.6kg, compound probiotics 1kg, L-lysine 0.3kg, DL-methionine 0.08kg, L-tryptophan 0.05 kg, L-threonine 0.12kg; The weight ratio of butyric acid bacteria, lactobacillus fermentum and bacillus subtilis in the ecological preparation is 2*10 3 :1:10.
[0093] Among them, the premix suitable for the diet of pigs in the growth stage contains vitamin A, 2,512IU, vitamin D per 1kg of diet 3 , 1,200IU, Vitamin E, 34IU, Vitamin K 3 , 1.5mg, Vitamin B 12 , 17.6 μg, Vitamin B 2 , 2.5mg, vitamin B 5 , 6.8mg, Niacin, 20.3mg, Choline Chloride, , 351mg, Manganese, 100mg, Iron, 100mg, Zinc, 100mg, Copper, 35mg, Iodine, 0.3mg, Cesium, 0.3mg.
[0094] Take the above-mentio...
Embodiment 3
[0096] The low-protein biological feed described in this example has the following formula: 72 parts of corn, 18 parts of soybean meal, 3 parts of bran, 1.5 parts of soybean oil, 0.4 part of stone powder, 1.5 parts of calcium hydrogen phosphate, 0.3 part of table salt, and 0.6 part of premix , 1 part of compound microecological preparation, 0.6 part of L-lysine, 0.05 part of DL-methionine, 0.08 part of L-tryptophan, 0.08 part of L-threonine; the butyric acid bacteria, fermented lactic acid The weight ratio of Bacillus and Bacillus subtilis is 0.2*10 3 :5:1. The premix formula is selected from the content disclosed in Example 1 or Example 2 according to what kind of ration the feed in this example is used for. Compared with the feed protein level of conventional feed, the feed in this embodiment has reduced by 4%, which greatly reduces the discharge of nitrogen source excrement, improves the utilization rate of nitrogen source, and can also significantly improve the growth per...
