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...

Abstract

The invention relates to low-protein biological feeds, which comprise the following components in parts by weight: 72 to 85 parts of corns, 6 to 18 parts of soybean meal, 3 to 6 parts of wheat bran, 0 to 1.5 parts of soybean oil, 0.4 to 0.8 part of limestone, 0.5 to 1.5 parts of calcium hydrogen phosphate, 0.3 to 0.6 part of table salt, 0.6 part of premix, 1 part of compound microecological preparation, 0.2 to 0.6 part of L-lysine, 0.05 to 0.12 part of DL-methionine, 0.03 to 0.08 part of L-tryptophan and 0.08 to 0.13 part of L-threonine, wherein the compound microecological preparation comprises butyric acid bacteria, fermentative lactobacillus and bacillus subtilis. According to the low-protein biological feeds, the utilization rate of a nitrogen source in animal feeds can be remarkably increased, the emission of the nitrogen source is reduced, the growth performance of animals can be improved, and remarkable technical effects are achieved.

Description

technical field [0001] The invention relates to an animal feed, in particular to a low-protein biological feed and a preparation method thereof. Background technique [0002] With the continuous expansion of the scale of my country's aquaculture industry, many problems caused by the aquaculture industry are becoming more and more serious. Among them, the problem of environmental pollution is the most serious, and the pollution of nitrogen sources is the most serious. Due to the large scale of the breeding industry, the amount of animal excrement produced is huge, especially the discharge of nitrogen sources. For the total nitrogen intake of fattening pigs in the growing period, about 15% is excreted in the form of manure nitrogen, and about 50% It is excreted in the form of urine nitrogen, and nearly 52% of the nitrogen in feces and urine is discharged into the atmosphere in the form of odor, and 48% enters the soil, which is very serious to the pollution of the environment....
