Problems solved by technology

[0005] However, the existing antibiotic-free fermented feed is generally based on raw grains or concentrated feeds based on raw grains as the fermentation substrate. The cost of raw grains is high, and the supply of sources is insufficient. Raw grain-based concentrated feed has high energy. On the basis of the feed utilization rate and conversion rate of the existing pigs, there is also a lot of raw grain energy that cannot be used in the feed. The fermented feed without antibiotics passes through the pig's stomach, and this part of energy is difficult to recover and reuse. utilization, which results in a waste of food resources

Embodiment 1

[0031] The low-cost fermented feed for pigs without antibiotics of the present embodiment is prepared by the following method:

[0032] 1) Take the shiitake mushroom sticks after picking the 4th batch of shiitake mushrooms, and culture them in an environment with a temperature of 20°C and a humidity of 85% for 7 days (let the mushroom mycelium in the mushroom sticks grow freely), and the mushroom sticks have a large number of bacteria After the filaments grow out, take out the fungus sticks, tear off the plastic fungus bag on the surface, break up the fungus sticks and remove impurities (soil and moldy parts), air-dry and dry to a water content of 14%, crush and pass through a 10-mesh sieve to obtain shiitake mushroom chaff;

[0033] 2) According to the following mass percentages, mix the champignons obtained in step 1) with potato dregs, corn flour, and soybean meal to prepare a fermentation substrate: 28% of shiitake chaff, 32% of potato dregs, 12% of cornmeal, 18% of soybea...

Embodiment 2

[0040] The low-cost fermented feed for pigs without antibiotics of the present embodiment is prepared by the following method:

[0041] 1) Take the shiitake mushroom sticks of the 4th batch of shiitake mushrooms after picking, and culture them in an environment with a temperature of 25°C and a humidity of 80% for 7 days (let the mushroom mycelium in the mushroom sticks grow freely), and the mushroom sticks have a large number of bacteria After the filaments grow out, take out the fungus sticks, tear off the plastic fungus bag on the surface, break up the fungus sticks and remove impurities (soil and moldy parts), air-dry and dry to a water content of 14%, crush and pass through a 15-mesh sieve to obtain shiitake mushroom chaff;

[0042] 2) According to the following mass percentages, the champignons of mushrooms obtained in step 1) are mixed evenly with potato dregs, corn flour, and soybean meal to prepare a fermentation substrate: 32% of shiitake mushroom chaff, 28% of potato...

Embodiment 3

[0049] The low-cost fermented feed for pigs without antibiotics of the present embodiment is prepared by the following method:

[0050] 1) Take the shiitake mushroom sticks that have been picked for the 4th batch of shiitake mushrooms, and culture them in an environment with a temperature of 22°C and a humidity of 83% for 7 days (let the mushroom mycelium in the mushroom sticks grow freely), and the mushroom sticks have a large number of bacteria After the filaments grow, take out the fungus sticks, tear off the plastic fungus bag on the surface, break up the fungus sticks and remove impurities (soil and moldy parts), air-dry and dry to a water content of 14%, crush and pass through a 20-mesh sieve to obtain shiitake mushroom chaff;

[0051] 2) According to the following mass percentages, the mushroom chaff obtained in step 1) is mixed with potato dregs, corn flour, and soybean meal to prepare a fermentation substrate: 30% of shiitake mushroom chaff, 30% of potato residue, 15%...

Abstract

The invention discloses a low-cost antibiotic-free fermented feed for pigs and a fattening pig feed. The fermented feed is prepared by the following method: 1) placing fungus bags or fungus sticks with lentinus edodes picked in an environment at a temperature of 20-25 DEG C and humidity of 80-85% for culturing for 7 days, and taking out and treating the cultured material to obtain lentinus edodesfungus residues; 2) mixing the obtained lentinus edodes fungus residues with potato residues, corn powder and soybean meal to prepare a fermentation substrate; 3) mixing a composite bacterial agent, acomplex enzyme preparation, brown sugar and water to obtain mixed bacterial strains; and 4) mixing the obtained fermentation substrate with the obtained mixed strains to obtain a fermentation mixturein a fermentation tank, and conducting fermentation at 32-38 DEG C for 90-96h. The fermented feed is adopted to prepare the fattening pig feed, so that the daily weight gain of market pigs is improved, the feed ratio is reduced, the utilization rate and conversion rate of the feed are high, the cost is low, and the feeding effect is good; and the fattening pig feed improves the dressing percentage and lean meat percentage of market pigs, does not contain antibiotic, and improves the quality of pork.

Description

technical field [0001] The invention belongs to the technical field of pig feed, in particular to a low-cost fermented feed for pigs without antibiotics and feed for fattening pigs. Background technique [0002] In the process of livestock and poultry farming, it is common to use antibiotics as feed additives to improve animal health and increase the conversion rate of animals to feed. The application of antibiotics in animal husbandry accounts for about half of the total use of antibiotics. Long-term addition of antibiotics and other drugs to feed during animal husbandry production can cause the emergence of drug-resistant strains, drug residues in livestock and poultry products such as meat, eggs, and milk, and environmental pollution, causing serious harm to human health and public health safety. [0003] With the development of society and economy, people pay more and more attention to issues such as food safety, public health and environmental protection. Under this bac...
