Embodiment 1

[0016] A kind of pollution-free laying hen feed, the said pollution-free laying hen feed contains eucalyptus leaf extract of 0.2% and wormwood powder of 3.5% by mass.

[0017] Further, the preparation method of the eucalyptus leaf extract comprises the following steps:

[0018] (1) Wash and chop eucalyptus leaves, add a compound enzyme solution with 8 times the mass fraction of eucalyptus leaves, enzymolyze at 33°C for 1.8 hours, then heat to boiling, keep warm for 15 minutes, and then filter to obtain filtrate and filter residue;

[0019] (2) Soak the ethanol solution of the above-mentioned filter residue plus 6 times of the filter residue at 55°C for 3 hours, then filter, recover ethanol, and obtain an ethanol extract;

[0020] (3) Combining the filtrate and the ethanol extract to obtain the eucalyptus extract, and then freeze-drying to obtain the eucalyptus extract.

[0021] Further, the mass percentage of the compound enzyme in the compound enzyme liquid is 5.5%.

Abstract

The invention discloses a harmless laying hen feed, and relates to the technical field of chicken breeding. The harmless laying hen feed comprises, in percentage by mass, 0.2-0.3% of a eucalyptus leafextract and 3.5-6.8% of argy wormwood powder. By adopting a rationally proportioned feed formula, the harmless laying hen feed has richer feed nutrients. Thus, growth cycle of laying hens fed with the feed is shortened by about 10 days with egg yield increased by about 15%.

Description

technical field [0001] The invention belongs to the technical field of chicken breeding, and in particular relates to a pollution-free laying hen feed. Background technique [0002] At present, the additives in laying hen feed on the market are mostly antibiotics, chemical synthetic drugs, hormones, etc. The chickens raised by these additives generally have toxic and harmful substances, hormones and antibiotic residues, and the ratio of calcium to phosphorus, amino acid ratio and The ratio of energy to protein is seriously unbalanced, and other nutrients need to be artificially added again to improve, which greatly increases the cost of feed. Contents of the invention [0003] The purpose of the invention is to provide a kind of pollution-free laying hen feed aiming at the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A pollution-free laying hen feed contains 0.2-0.3% of eucalyptus leaf extract and 3.5-6...
