Abstract
The invention discloses trace element premixing feed for a suckling piglet. 100-250g of ferrous bisglycinate chelate, 100-200g of zinc glycinate, 100-350g of copper glycine, 50-150g of manganese sulfate, 0.25-0.75g of potassium iodide and 35-100g of yeast selenium and the balance of premixing feed carrier are contained in the premixing feed per kilogram; In the premixing feed, contents of various trace elements are more balanced through reasonably and completely preparing the various trace elements, thereby effectively promoting the growth of the suckling piglet, improving the utilization ratio and the health state of the feed and simultaneously and remarkably reducing the pressure of heavy metal to environmental pollution.
Description
Technical field
The present invention relates to a kind of feed addictive, especially a kind of trace element premixing feed for suckling piglet.
Background technology
A large amount of tests confirm to add high-copper in diet (130～250mg/kg) (copper sulphate forms) can be accelerated growth in piglets, improve efficiency of feed utilization and immunity, but discover that high-copper can reduce pig absorbing iron, zinc.Therefore, when using high-copper, to add the iron (150～170mg/kg) and zinc (150～170mg/kg) of high dose simultaneously.Cause the feed palatability to descend so on the one hand, on the other hand, iron zinc can not absorb in vivo, excretes, and causes environmental pollution.Amino acid trace element chelated thing is as a kind of novel non-pollution feed addictive, good palatability, the absorptivity height, simultaneously can promote growth of animal, reduce food consumption, improve efficiency of feed utilization, and have certain sterilization and improve the effect of animal immune function, thereby become the Recent study focus, but research all is result of use and the addition that is limited to a certain trace element, causes between the trace element proportioning unreasonable.
Summary of the invention
The technical problem to be solved in the present invention provides reasonable mixture ratio trace element premixing feed for suckling piglet between a kind of trace element.
For solving the problems of the technologies described above, contain in every kilogram of premix of the present invention: ferrous bisglycinate chelate 100～250 grams, glycine zine 100～200 grams, cupric glycinate 100～350 grams, manganese sulfate 50～150 grams, KI 0.25～0.75 gram, yeast selenium 35～100 grams, surplus is a premix carrier.
Preferred premix carrier is zeolite powder or bentonite.
Adopt the beneficial effect that technique scheme produced to be: the present invention is by rationally, prepare various trace elements (copper, iron, zinc etc.) comprehensively, wherein iron, copper, zinc, manganese, iodine, Se content are respectively 10-25g/kg, 25-40g/kg, 10-25g/kg, 15-25mg/kg, 150-550mg/kg, 50-150mg/kg, make the content balance more between each trace element, thereby effectively promote newborn growth in piglets, improve efficiency of feed utilization and health status, significantly reduce heavy metal environmental pollution pressure simultaneously.
Use this prescription, can substitute newborn piglet high-copper microelement pre-mix material fully, piglet production performance, the price of deed, health status increase, particularly copper, iron, zinc discharge rate reduce more than 50%, alleviate the pollution of heavy metal greatly to environment, can obtain the economical, societal benefits bumper harvests, meet national security healthy aquaculture policy.
Use ferrous bisglycinate chelate, glycine zine, cupric glycinate, yeast selenium fully as raw material, substitute inorganic salts with organic trace element, proportioning is safer, reasonable.
