Problems solved by technology

At present, with the scale of breeding, in order to increase the egg production rate of laying hens and reduce the disease rate of laying hens, various auxins, antibiotics, hormones, etc. are often added to chicken feed, although the egg production rate of laying hens has been improved. , but the taste and nutritional value are far inferior to domestic chicken eggs, and the egg yolk is white, the egg white is thin, and the storage time is short and easy to deteriorate

Embodiment 1

[0024] An additive, calculated in parts by weight, includes the following raw materials:

[0025] 50 parts of lemon peel extract, 32 parts of tea leaves, 12 parts of pig liver and 2 parts of compound enzyme. The compound enzyme is a mixed enzyme of cellulase and neutral protease.

[0026] Lemon peel extract is prepared by the following method:

[0027] Add lemon peel to water for boiling treatment, the boiling time is 20min, then cool to 40°C, beating, then add amylase for enzymatic hydrolysis, the enzymatic hydrolysis time is 3h, then heat up and inactivate, filter, and concentrate the filtrate at low temperature Dried to obtain lemon peel extract. The addition of amylase is 0.5% of lemon peel weight.

[0028] The preparation method of additive, comprises the following steps:

[0029] 1) beating: mixing the tea leaves and pork liver for beating to obtain a slurry;

[0030] 2) Enzymolysis: heat the slurry to 60°C, then add compound enzymes, enzymolyze for 2 hours, then he...

[0032] An additive, calculated in parts by weight, includes the following raw materials:

[0033] 60 parts of lemon peel extract, 30 parts of tea leaves, 6 parts of pig liver and 5 parts of compound enzyme. The compound enzyme is a mixed enzyme of cellulase and neutral protease.

[0034] Lemon peel extract is prepared by the following method:

[0035] Add lemon peel into water for boiling treatment, the boiling time is 30min, then cool to 60°C, beating, then add amylase for enzymolysis, the enzymolysis time is 1h, then heat up and inactivate, filter, and concentrate the filtrate at low temperature Dried to obtain lemon peel extract. The addition of amylase is 0.9% of lemon peel weight.

[0036] The preparation method of additive, comprises the following steps:

[0037] 1) beating: mixing the tea leaves and pork liver for beating to obtain a slurry;

[0038] 2) Enzymolysis: heat the slurry to 54°C, then add complex enzymes, enzymolyze for 3 hours, then heat up and inactiva...

Embodiment 3

[0040] An additive, calculated in parts by weight, includes the following raw materials:

[0041] 54 parts of lemon peel extract, 40 parts of tea leaves, 8 parts of pig liver and 6 parts of compound enzyme. The compound enzyme is a mixed enzyme of cellulase and neutral protease.

[0042] Lemon peel extract is prepared by the following method:

[0043] Add lemon peel to water for boiling treatment, the boiling time is 23min, then cool to 46°C, beating, then add amylase for enzymolysis, the enzymolysis time is 3h, then heat up and inactivate, filter, and concentrate the filtrate at low temperature Dried to obtain lemon peel extract. The addition of amylase is 1.1% of the weight of the lemon peel.

[0044] The preparation method of additive, comprises the following steps:

[0045] 1) beating: mixing the tea leaves and pork liver for beating to obtain a slurry;

[0046] 2) Enzymolysis: heat the slurry to 55°C, then add complex enzymes, enzymolyze for 3 hours, then heat up and...

Abstract

The invention provides a formula feed for improving the stress resistance of laying hens. The formula feed is prepared from, by weight, 500-560 pars of corn, 160-210 parts of cassava, 150-180 parts ofoat bran shell powder, 80-100 parts of scallop powder, 40-50 parts of seaweed powder, 8-15 parts of edible oil, 15-32 parts of additives and 1-3 parts of trace elements, wherein the additives are prepared from, by weight, 50-60 parts of lemon peel extracts, 30-40 parts of tea, 6-12 parts of pig livers and 2-6 parts of a complex enzyme. By means of the feed, not only can the anti-stress ability ofthe laying hens be improved, but also the egg quality can be improved and the laying rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a compound feed for improving stress resistance of laying hens. Background technique [0002] Compound feed is based on different growth stages of animals, different physiological requirements, nutritional needs of different production purposes and on the basis of feed nutritional components, according to scientific formula, a variety of feed raw materials from different sources are processed and pulverized, and uniformly mixed and prepared according to a certain proportion. made feed. [0003] The breeding cycle of laying hens, that is, the cycle from the newly hatched chicks to the final elimination and sale is generally 17 months, divided into two stages: the previous stage is the growth period, that is, from the newly hatched chicks to the start of laying eggs The period is generally 0-5 months, a total of 5 months; the latter stage is the egg-laying period, that is...
