Description
Technical field
The present invention relates to feed additive field more particularly to a kind of additions reducing Feed Copper, zinc usage amount
Agent and its production technology.
Background technology
Feed addictive refers to a small amount of or micro substance added during Feed Manufacturing processing, use, feed addition
Dosage is seldom in feed but effect is notable for agent.Feed addictive is the raw material that modern feed industry necessarily uses, to strengthening base
Plinth feed nutritive value improves breeding performonce fo animals, ensures animal health, saves feed cost, improves the side such as livestock products quality
Face has obvious effects on.Zinc oxide as a kind of common feed addictive, play the role of it is very positive, such as research shows that
2500-4000mg/kg zinc is added in early-weaned piglets daily ration, can significantly reduce the diarrhea rate of piglet.But with oxidation
Zinc also brings the problem of series in the application of feed, for example high zinc can inhibit piglet to the absorption of iron, reduces the immune of piglet
Ability leads to slightly long random, the skin tarnish of piglet hair.Most important is exactly the common zinc oxide that conventional method is process,
It is often accompanied by heavy metals exceeding standard, the problems such as absorptivity is low, a large amount of unabsorbed zinc oxide are excreted with excrement, to soil, water
Body etc. causes seriously to pollute.
Research shows that adding the copper sulphate of 250mg/kg in feed, there is 95% or more copper ion to be absorbed and utilized, it is a large amount of in this way
Copper by metabolic cycles, a part is deposited in body tissue, and significant fraction is excreted（90%）, this is not only resulted in
Animal body slow poisoning, tissue residue increase the waste with resource, it is often more important that animal tissue remains and a large amount of excretion meetings
Very important influence and harm are come to the mankind and entire ecological chain health care belt.
Clay-activity copper with poultry, aquatic products and other animals, can improve as feed addictive first Application
Intestinal flora；By controlling pathogenic flora and the growth of beneficial bacterium being promoted to prevent flora imbalance；Promote digestion and absorbs；Reduce poultry
Heavy metal pollution in fowl breeding process, is good for the environment in this way, has very big utilization background.
Invention content
The object of the present invention is to provide it is a kind of reduce Feed Copper, zinc usage amount additive, the use of the additive
