Problems solved by technology

So far, the shortage and waste of protein feed still exist in the production of compound feed. The typical performance is that the energy of compound feed does not reach the level specified in the standard, and the protein content exceeds the level specified in the standard, resulting in low energy and high protein, and waste. protein

Embodiment 1

[0023] The specific preparation method of earthworm protein:

[0024] Earthworms are used as raw materials to be frozen into powder with liquid nitrogen, then added to water for grinding, heated to 60°C, and the pH value is adjusted to 6.5, then papain and alkaline protease are added, and the hydrolysis reaction is carried out for 12 hours; then adjusted to adjust the pH value to 4.5, and lower the temperature to 40°C, then add acid protease and neutral protease, carry out hydrolysis reaction for 6 hours, and then separate, and the separated liquid is concentrated to obtain the earthworm protein.

Embodiment 2

[0026] The specific preparation method of earthworm protein:

[0027] Earthworms are used as raw materials to be frozen into powder with liquid nitrogen, then added to water for grinding, heated to 70°C, and the pH value is adjusted to 7.0, then papain and alkaline protease are added, and the hydrolysis reaction is carried out for 8 hours; then adjusted to adjust the pH value to 5.5°C, and lower the temperature to 50°C, then add acid protease and neutral protease, carry out hydrolysis reaction for 4 hours, and then separate, and the separated liquid is concentrated to obtain the earthworm protein.

Embodiment 3

[0029] A feed for improving the production performance of laying hens, calculated by weight percentage, comprising the following raw materials:

[0030] 500 parts of corn, 100 parts of soybean meal, 50 parts of wheat, 80 parts of rice bran meal, 90 parts of earthworm protein of Example 1, 20 parts of vegetable oil, 70 parts of peanut meal, 1 part of compound amino acid, 2 parts of compound enzyme, 1 part of trace element, 1 part of phytase and 10 parts of calcium hydrogen phosphate.

[0031] The compound amino acid is a mixture of methionine, threonine and lysine.

[0032] The compound enzyme is composed of cellulase, β-glucanase, xylanase, α-amylase and carrier shell powder.

[0033] Trace elements are composed of ferrous sulfate, zinc sulfate, copper sulfate, manganese sulfate, calcium iodate and stone powder as a carrier.

[0034] The parts by weight of each raw material in the traditional Chinese medicine additive are: 20 parts of Houttuynia cordata, 10 parts of purslane...

Abstract

The invention provides a feed for improving production performance of laying hens. The feed comprises the following raw materials in parts by weight: 400-600 parts of corn, 100-150 parts of soybean meal, 40-60 parts of wheat, 30-60 parts of fish meal, 50-100 parts of earthworm proteins, 10-30 parts of plant oil, 40-60 parts of pig bone meal, 1-3 parts of composite amino acid, 2-4 parts of composite enzymes, 1-2 parts of trace elements, 20-40 parts of a traditional Chinese medicine additive, 0.5-1 part of phytase and 5-10 parts of calcium hydrogen phosphate. The earthworm proteins are preparedby subjecting earthworms to enzymolysis, conducting separation, and concentrating the separated liquid. The traditional Chinese medicine additive comprises the following raw materials: cordate houttuynia, purslane, epimedium herb, baikal skullcap roots, manyprickle acanthopanax roots and codonopsis roots. The feed improves a protein utilization rate, improves digestion functions of laying hens inlater stage, and improves production performance and breeding economic benefits.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to a feed for improving the production performance of laying hens. Background technique [0002] In recent years, with the increase in the number of poultry breeding, the pressure of environmental protection and energy saving is increasing. The pollution of the poultry industry mainly comes from the excreta of nitrogen, phosphorus, trace elements, etc. These substances mainly come from undigested feed in the feed. Nutrients. These harmful substances not only destroy the environment of the chicken house, but also pose a great threat to the health of poultry, increase the incidence of poultry disease, and reduce the economic benefits of poultry farmers. Hazard to human health. [0003] my country is the country with the largest number of laying hens in the world, but the overall production level of laying hens in my country is not high at present, and there is a big gap with the world'...
