Description

Broiler feed for improving gizzard size

Technical Field

The invention relates to the technical field of animal feed, in particular to broiler feed for improving gizzard size.

Background

The broiler feed is prepared from two types of powder and granules in the current market. The existing powder has the defects of high powder content (15-25%), low feed intake and slow weight gain, but has the advantages of large gizzard, healthy intestinal tract, low requirement on processing equipment and low processing cost; compared with powder, the granule has the advantages of low powder content (below 4 percent), easy ingestion, small gizzards, fast digestion, easy occurrence of intestinal tract problems, relatively high process requirements, granulation equipment and high processing cost.

Disclosure of Invention

In view of the above, the invention aims to provide a broiler feed capable of improving the gizzard size, and simultaneously has the advantages of granules and powder.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the broiler feed for improving the gizzard size comprises the following components in percentage by mass: 55-60% of corn, 4-7% of soybean oil, 15-25% of soybean meal, 2-5% of corn protein powder, 2-5% of peanut meal, 1-3% of rapeseed meal, 1-5% of vinasse, 1-4% of rice bran, 1-1.5% of mountain flour, 1-1.5% of calcium hydrophosphate, 0.2-0.4% of salt, 0.1% of choline chloride, 0.7% of various amino acids, 0.05% of compound vitamin, 0.1% of various trace elements, 0.1% of probiotics, 0.1% of acid preparation and 0.03% of plant essential oil.

The preparation process of the broiler feed for improving the gizzard size comprises the following steps:

1) crushing raw materials: crushing corns, wherein the aperture of a screen of a crusher is 5-8 mm, and after crushing, sieving the corns by a 10-mesh screen, and dividing the corns into two parts, namely an upper part and a lower part, which are 10 meshes; crushing the bean pulp, the peanut pulp and the vinasse, wherein the mesh opening of a crusher is 2.0mm, and sieving is not needed after crushing; other raw materials do not need to be crushed;

2) and (3) granulating: pulverizing corn, sieving with 10 mesh sieve, mixing with pulverized raw materials of other raw materials and raw materials not requiring pulverization according to formula ratio, and making into granule;

3) mixing: pulverizing semen Maydis, sieving with 10 mesh sieve, mixing with soybean oil and granule.

Compared with the prior art, the broiler feed for improving the gizzard size has the following advantages:

the broiler feed for improving the gizzard size has the advantages of granules and powder, is low in powder content, high in feed intake, large in gizzard size, low in manufacturing cost relative to the granules, superior to the powder and the granules in feed performance, and lower in meat manufacturing cost than the powder and the granules.

Detailed Description

Unless defined otherwise, technical terms used in the following examples have the same meanings as commonly understood by one of ordinary skill in the art to which the present invention belongs. The test reagents used in the following examples, unless otherwise specified, are all conventional biochemical reagents; the experimental methods are conventional methods unless otherwise specified.
