The invention relates to a production method of poultry feed, in particular to a production method of early-stage crushed feed for young poultry.
Background
The chick feed appearing on the market at present is all the granule material, and the granule material is unfavorable for chick to eat and digest and absorb, and traditional chick feeding mode is: the broken rice grains are 7 days old, so that the rice can be conveniently eaten and digested; or directly feeding the granular feed produced by a ring mould with the diameter of 2.0mm-2.2mm for 4 weeks. Although the problem that the young birds are difficult to feed with the large granulated feed is solved, the nutrition is single from the aspect of nutrition balance of the young birds, particularly the young birds which are just born are low in disease resistance rate, and if the nutrition is unbalanced, the feed intake is insufficient, the feeding problems of low survival rate, slow growth and the like are easily caused. The feed produced by the ring die with the aperture of 2.0-2.2mm meets the nutritional requirements of young poultry for growth through a specific feed proportion, but the problems of slow weight gain, high material-weight ratio and high production cost of the young poultry with the age of 0-2 weeks can occur. In conclusion, the feed specially aiming at the young poultry of 0-2 weeks old is lacked in the market at present, the feeding and nutrition requirements of the young poultry cannot be met, the death rate of the young poultry is high, the weight gain is low, and the improvement of the production benefit of poultry cultivation is not facilitated.
Disclosure of Invention
The invention aims to provide a production method of early-stage broken feed for young birds, which aims to overcome the defects of unbalanced nutrition and low survival rate of the young birds in the early stage of the young birds in the prior art, and is particularly suitable for the young birds of 0-2 weeks old.
The purpose of the invention can be realized by the following technical scheme:
a production method of early-stage crushed material of young poultry comprises the following steps:

(2) mixing: feeding the raw material components into a mixer for mixing;
(3) granulating and forming: preparing the uniformly mixed powder into granules by using a ring die granulator, and cooling by using a counter-flow cooler;
(4) crushing and sieving: crushing and screening the granular materials by adopting a poultry material crushing and screening machine to obtain young poultry feed with the particle size of 4-12 meshes;
(5) bagging and storing.
Further, the aperture of the ring die granulator is 3.8mm, and the length-diameter ratio is 1: 14; the water content of the cooled granular material is +/-0.5%, and the temperature is 0-5 ℃ higher than the normal temperature.
Further, the temperature of the ring die granulator is 85-90 ℃, and the steam pressure is 3-4.5 kg.
Further, the impurity removal comprises air separation impurity removal and magnetic separation iron removal.
Further, the pulverized raw material was sieved using a sieve having an aperture of 2.0 mm.
The aspect ratio is the ratio of the thickness of the ring mode to its pore size.
Further, the young poultry feed comprises the following raw material components in parts by weight: 55 parts of second-level corn; 29 parts of 46% soybean meal; 1 part of rice bran; 4 parts of puffed soybeans; 4 parts of wheat middling; 1 part of soybean oil; 1 part of stone powder; 1 part of calcium hydrophosphate.

Example 3
This example is an experimental comparison of the crushed material of example 1 and the existing feed for feeding ducklings of the same age of day.
The comparative test is as follows: 60 ducklings (age of 1 day) with the same age of day are selected and randomly divided into three groups of 20 ducklings. Feeding by comparing granular material group, broken rice group and broken material group, and weighing after feeding for 14 days.
Wherein the granular material is produced by directly using a ring die with the diameter of 2.0mm-2.2 mm;
broken rice is the material after the rice grains are broken;
the crushed material is the material obtained by granulating in the ring die granulator of example 1 and then crushing by the crusher.
The test data are as follows:
as can be seen from the results of the tests,
if the ducklings of 0-2 weeks old are directly fed by the granular feed produced by the ring die with the diameter of 2.0-2.2mm, the feed weight ratio of the ducklings is larger, which indicates that the absorption efficiency of the feed is not high;
if the granulated feed and the broken rice grains are used for feeding simultaneously, the survival rate and the material weight ratio are improved, but a certain gap still exists compared with the single broken feed of the invention.
Example 4
This example is an experimental example, in which crushed material with a particle size smaller than 12 meshes is used to feed ducklings (age of 1 day) with the same age of day, and the specific experimental process is as follows: 40 ducklings (age of 1 day) with the same age of day are selected and randomly divided into two groups of 20 ducklings. The crushed material and the small crushed material with the grain size of less than 12 meshes in the embodiment 1 of the invention are respectively fed, and the crushed material and the small crushed material are weighed after being fed for 14 days.
The test data are as follows:
it can be seen that if a smaller size is used, such as the 0.6mm pellet feed of chinese patent CN 109717316a, the smaller size is not conducive to weight gain and survival of the ducklings, as can be seen from the data in example 4: the material weight ratio of the small crushed materials is extremely high, because the feed intake habit of the poultry feed cannot feed too small feed, so that waste is caused; and under the condition of the same feeding frequency, the feeding time is 2 times of that of the crushed material, so that the energy of the young poultry is excessively consumed, and the growth is influenced. For example: the crushed duck can be eaten for 50 times, and the fine crushed duck can be eaten only after 100 times of eating.
