Abstract
The invention discloses a granulum fodder with the diameter of 2.0 mm, and a preparation method of the granulum fodder. The granulum fodder is 2.0 mm in diameter, 0.5-2.0 d in length, and 1-3.0 kg in rigidity. According to the invention, a 420 stainless steel ring die with the diameter of 2.0 mm and the ratio of compression of 1:(5-8) is adopted; and a 420 stainless steel ring die with the diameter of 3.0-4.5 mm and the ratio of compression of 1:(5-10) is adopted. Tests show that the scheme is feasible. According to the invention, the following advantages are achieved: the granulum fodder with the diameter smaller than 2.0 mm can completely replace crushed materials, and moreover, the product quality is more stable, and the production efficiency is improved. During the using of the granulum fodder, the food consumption and the growth effect of the broiler chicken at the early stage are not affected, the crowd uniformity can be better improved, the sick chicken amount can be reduced, and the mortality and elimination rate is also reduced, and therefore, a better cultivation benefit is brought to farmers.
Description
Technical field
The present invention relates to the granule feed and replace broken feed, particularly meat chick early stage and mid-term feed granule feed the preparation method.
Background technology
In traditional broiler fodder is made, to broiler growth early stage (0-25 age in days) feed because of the search for food characteristic of aspect of broiler growth stage, the bulky grain feed of can not searching for food, often adopt broken material, and broken material is through the first granulation material of modified granulation (granularity generally adopts ￠ 3.0mm to reach with the molded work of pressed on ring) by mixed powder, and then become the broken material of suitable particle size according to the stage crushing of feeding, can produce the screenings of a part lower than granulometry in the process of making at broken material, this part screenings is according to technological design, tending to enter storehouse to be granulated granulates again.Through a large amount of the detection, find, cause the separation of a part of feed ingredient because of the grading meeting in broken material manufacturing process, thereby cause the broken material finished product nutritive index of output unbalanced, the product coefficient of variation of different parts is larger, because nutritional labeling makes a variation larger, often cause product to cause in actual use brooding chicken body condition difference, thereby affect the whole uniformity, finally can affect the result of use of product.
Be subject to the impact of conventional feed technique, for a long time meat chick early stage mixed feed and mid-term the transition stage mixed feed, often all adopt the feed of broken state, the characteristic of searching for food to adapt to this stage meat chick, meet the needs that it is searched for food.In the sample detecting process of the broken material randomness to produced, tend to occur that broken material detects the situation of index even part index number not up to standard severe overweight, as meat chick mixed feed 510 in early stage, sometimes detect the situation that the crude protein the possibility of result there will be 16-17%, also likely there will be detected value is more than 22%, and the formula Design standard is 20%, although the repetition measurement result is still like this.Such situation appears, be limited to that wet-chemical detection means in the past falls behind and the actual conditions of inefficiency, it is defective that we tend to be judged as this batch of product, can not dispatch from the factory, and search reason, and found that the formula execution accurately, do not find to mix the storehouse phenomenon simultaneously yet, the mixer mixture homogeneity is also up to standard, and final reason but can't effectively be analyzed out.
By means of the efficient detectability of near-infrared fast and stable, carried out the sample detecting of frequent property for the whole production process of broken material, the testing result of finding its near-infrared scanning of broken material sample that the different parts of same batch (date of manufacture is consistent) is taked but shows between each sample and often has larger difference, crude protein and the cinder aspect that grades particularly, exist indivedual values to depart from normal value larger, batch between, the coefficient of variation is too high, and standard deviation is extraordinary.
The main cause of analyzing this results abnormity of appearance may be the separation that the product after granulating causes composition after crushing and screening, the spy samples detection to the classifying screen screenings for this reason, find that the way it goes, as quality testing under 510 classification sieves is surveyed the not enough 17%(formula Design of crude protein value >=20% as a result).
Also for batch particulate material, carrying out the detection of the frequent property of multiple spot, find that particulate material stability is apparently higher than broken material simultaneously.
By comparative analysis, it is to cause exactly the separation of part material component in shattering process that basic identification causes the unsettled main cause of broken material quality, thereby has affected the stability of product, has also changed the mixture homogeneity effect of expection.
Broken material is granulated again because there being the part screenings to be back to storehouse to be granulated in addition, will certainly reduce production efficiency than particulate material, as broiler growth mixed feed 510 broken materials in early stage, its screenings refluxes and generally accounts for the 25-30% of particulate material, and its classifying screen backflow of broiler growth mixed feed in mid-term 511 broken materials also can account for the 20-25% of particle.Simultaneously the repeated high temperature granulating because refluxing, cause certain loss to part thermal sensitivity nutritional labeling, also easily causes unstable (the flower material, black material many) of product appearance state, may cause the market complaint.
Since the particulate material effect stability is apparently higher than broken material, if being wanted to mate particulate material by granularity with it, broken material replaces, just can solve the problem of product stability.Traditional meat chick material is made the material type, it is generally the broken material that the 0-21 age in days adopts the 1.5-3.0mm granularity, before needing to be replaced with stage of 511 particulate material before and after broiler growth to 21 age in days, often can adopt again granularity 511 broken materials (granularity 2.0-4.0mm) larger than 510 granularities to realize transition, and the ring mould of making broken material is all generally the above ring mould of 3.0mm.According to broiler growth early stage and primary stage in the mid-term characteristic of searching for food to the feed size, attempt using the thinner ring mould of granularity to carry out the production particulate material and replace whether broken material is feasible has become the problem of our research.But use small-bore ring mould production granule fowl material instead and be applied to the broken material that growth material in early stage replaces conventional type, also be not seen at present report in industry and carry out, if success of the test, can solve the unsettled situation of broken material quality, reduce the frequency and quantity that defective material returns machine, also can enhance productivity to a certain extent.
Summary of the invention
Unstable in order to solve the broken material quality, the actual conditions that production efficiency is low, adopt the granule material of suitable particle size to replace broken material, both improved product stability, also improved production efficiency, reduced time machine quantity of defective work, also can be the user reliable and stable product is provided simultaneously.The invention provides a kind of ￠ 2.0mm meat chick early stage and mid-term the granule feed replace the preparation method of broken feed.
