Abstract
The present invention relates to the field of animal nutrition, and particularly relates to a trace element premix feed and weaned piglet compound feed. The trace element premix feed does not contain copper sulfate, but contains copper citrate. The compound feed can decrease the amount of copper used in the feed by more than 88%, improve average daily gain (ADG), average daily feed intake (ADFI) and feed to gain ratio (F/G) of piglets compared with high dose copper sulfate, increase lysozyme concentration of serum by more than 50.62%, reduce diarrhea rate of piglets by more than 66.67%, and decrease fecal copper content by more than 88.76%; the above data has highly significant differences (P<0.01) compared with the control group.
Description
Technical field
The present invention relates to Animal nutrition field, particularly a kind of weanling pig trace element premixing feed and mixed feed.
Background technology
Copper is the required trace element of animal, at promotion growth of animal with improve in immunity of organism and have important function.1945, Brude studied discovery first, and the copper sulphate adding high dose can significantly improve the production performance of pig.After this, high-copper just widely uses in animal feed.At present, in Weanling pig compound feed, the addition of copper, up to 150 ~ 200mg/kg, is more than 10 times of normal needs.
High dose uses copper sulphate, all there is great potential safety hazard to animal self, ecological environment and animal products.If use high-copper in feed, then need to add high ferro and high zinc compatibility with it, this just easily causes copper in animal's liver, Zn content exceeds standard, even produce liver sex change, occur poisoning symptom.After animal consumption high-copper, most copper ion directly can not be excreted by absorbing, and copper is non-degradable material, if accumulated in water body and soil for a long time, and can the heavy damage ecological balance.The oxide precursor that copper still enlivens, high-copper can accelerate muscle lipid oxidation, threatens animal products safety.Therefore, high-copper has become the another large suffering after diet relaying antibiotic.
In order to solve all drawbacks that high doses applied copper sulphate in actual production brings, developing organic copper has become current research focus.The copper of the organic copper that feed and breeding enterprise use now mainly protein form and amino acid form, however this kind of organic copper to add cost high, detection method is complicated, promotes difficulty larger.Research finds, citric acid can be used as ligand and copper generation chelation, formation steady chemical structure, the copper citrate that biological value is high, thus promotes that enteron aisle is to the absorption of copper.Thus a kind of weanling pig trace element premixing feed containing copper citrate and mixed feed is developed, to filling up, domestic feeding copper citrate is blank, promote the update of feeding organic copper, promote feed industry transition and upgrade and ensure that animal husbandry sustainable health development is significant.
Summary of the invention
In view of this, the invention provides a kind of weanling pig trace element premixing feed and mixed feed.This mixed feed, can reduce Feed Copper consumption more than 88%, compared with high dose copper sulphate, can improve piglet average daily gain (ADG), average daily ingestion amount (ADFI) and feed-weight ratio (F/G); Improve serum lysozyme concentration more than 50.62%; Reduce grice diarrhoea rate more than 66.67%; Reduce excrement copper content more than 88.76%.
In order to realize foregoing invention object, the invention provides following technical scheme:
