The trace element premixed feed comprises the following raw materials: basic cupric chloride, basic zinc chloride, hydroxymethionine manganese, hydroxymethionine iron, hydroxymethionine zinc, yeast selenium, calcium iodate, cobalt chloride, mineral oil, calcium stearate, ethoxyquinoline and the balance of medical stone powder. The reasonable combination application of all components of the trace element premixed feed can meet requirements of piglets, promote the growth rate of the piglets, and reduce the diarrhea incidence rate of the piglets; and the mixing uniformity of the trace element premixed feed is improved, and the pollution to environment by trace elements in feces of piglets is reduced.
Description
Technical field
The invention belongs to pig and use the premix technical field, be specifically related to a kind of piglet trace element premixing feed.
Background technology
Direction develops and the genetic potential of piglet growth speed and meat productivity improves to intensifying along with pig industry production; In order to satisfy piglet requirement higher in industrial aquaculture to trace element; Addition as the iron of trace element, copper, manganese, zinc, iodine, selenium, cobalt is also increasingly high, and mostly adds with the form of inorganic salts; The trace element that adds with inorganic states in the daily ration can not satisfy the needs of animal, and more mineral matter is excreted, and causes environmental pollution.
In traditional piglet trace element premixing feed prescription, each element main source is the inorganic salts of Sulfates, exists problems such as absorption rate is low, big for environment pollution; Particularly pig industry adopts the zinc oxide control grice diarrhoea of high dose not only to influence other trace elements absorbed in recent years, and piglet growth of later stage speed is also caused certain influence.It is bad and mix uneven problem that minimum iodine, the cobalt of addition exists free-running property in the preparation technology of traditional trace element premixing feed.So, how to develop piglet trace element premixing feed safe, efficient, environmental protection and be called the research focus.
Summary of the invention
The object of the present invention is to provide a kind of piglet trace element premixing feed and preparation method thereof.
The present invention adopts following technical scheme:
A kind of piglet trace element premixing feed is characterized in that being made up of the raw material of following mass percent: the medical stone powder of basic copper chloride 3-6%, basic zinc chloride 4-6%, hydroxy methionine manganese 8-12%, hydroxy methionine iron 12-18%, methionine hydroxy zinc 12-16%, yeast selenium 5-8%, calcium iodate 0.02-0.04%, cobalt chloride 0.05-0.08%, mineral oil 0.2-0.5%, ethoxyquinoline 0.02-0.05%, calcium stearate 0.0014-0.0024% and surplus.
The granularity of medical stone powder is the 60-80 order.
The preparation method of piglet trace element premixing feed, (1) calcium iodate preliminary treatment takes by weighing calcium iodate, adds the calcium stearate of calcium iodate quality 1/50, and being crushed to granularity is the 100-120 order; (2) cobalt chloride preliminary treatment takes by weighing cobalt chloride, adds the calcium stearate of cobalt chloride quality 1/50, and being crushed to granularity is the 100-120 order; (3) the medical stone powder is added in the mixer, sprayed into simultaneously mineral oil 2-3 minute, mineral oil is evenly distributed on the medical stone powder, then other raw materials are added in the mixer, mixed 6-12 minute.
When piglet trace element premixing feed of the present invention used, piglet perfect compound feed per ton added 3-5 kilogram piglet trace element premixing feed of the present invention, directly fed after mixing or processed pellet and feed.
The reasonable use of components such as the basic copper chloride among the present invention, basic zinc chloride and hydroxy methionine iron, methionine hydroxy zinc, hydroxy methionine manganese has not only reduced the generation of grice diarrhoea rate, has also reduced the pollution to environment and soil; Calcium iodate and cobalt chloride are handled mixing free-running property and the mixture homogeneity that has improved iodine and cobalt through adding calcium stearate and ball mill; Mineral oil can stop the barrier action of moisture, makes the moisture absorption of not getting damp of dry sulfate, can prevent and treat the electrostatic interaction of dust pollution and particulate generation simultaneously; Medical stone contains aluminum silicate (feldspar), and adsorption capacity and bearing capacity are stronger, efficiently solves the problem of mobile difference of trace element premixing feed and easy caking, has improved the mixture homogeneity of trace element premixing feed.The reasonable combination of the various components of piglet trace element premixing feed of the present invention is used can satisfy the demand of piglet, promoting that function is remarkable on the piglet growth speed, also can effectively reduce the generation of grice diarrhoea rate and the pressure of environmental pollution.
