Abstract
The invention discloses application of zinc decanoic acid as a feed additive and as a growth promoter for feed, especially as a high dose ZnO substitute for swine feeding. The invention through a series of experiments proves that zinc decanoic acid can reduce the dosage of ZnO nearly by 80% in swine feed to achieve the same production performance, and even if in the required range of concentration of traditional nutritional zinc ions, the zinc decanoic acid also can significantly improve the production performance of pigs and chickens. Zinc decanoic acid can significantly reduce the application of zinc in animal husbandry, reduce production cost, reduce the toxic and side effect of high zinc and reduce environmental pollution, and is a zinc compound with unique advantage of growth promotion.
Description
Technical field:
The invention belongs to livestock and poultry cultivation field, be specifically related to capric acid zinc as the application of feed addictive or the application of feeding growth promoter, especially the application of high dose zinc oxide substitute for pig.
Background technology:
Zinc is one of essential trace element of animal.The zinc of nutritional need supplements mainly with the zinc of the inorganic form such as zinc sulfate in feed.After also finding that high dose zinc oxide high dose wean pig feed adds and can reduce diarrhea rate, improves daily gain texts at the beginning of the 1990s age, at global feedstuff industry, generally apply and come.But the Heavy-Metal-Contaminated Environments problem that a large amount of zinc sulfate and the application of high dose zinc oxide bring is also paid attention to gradually.From in recent years, European Union has forbidden high dose zinc oxide.Although China's wean pig feed allows to use the zinc of 2250ppm, this is also makeshift.Therefore efficiently, the novel fodder of safety and environmental protection is that Modern Animal Husbandry development is required with zinc product-derived.
Summary of the invention:
The object of this invention is to provide capric acid zinc in the application as feed addictive, the especially application by high dose zinc oxide substitute as pig.
The present invention found through experiments, and 150ppm capric acid zinc (calculating with zinc ion, lower same) can reach the improvement of 750ppm zinc oxide (calculating with zinc ion, lower same) to test pig production performance.As can be seen here, of the present invention using capric acid zinc can be the zinc ion low dosage in the situation that as additive, its growth promotion performance reaches the level of high dose zinc oxide.
Capric acid zinc of the present invention can be used as feeding high dose zinc oxide substitute and is applied in animal feed additive, plays anti diar rhea, somatotrophic effect, as promoting animal growth agent, and anti-diarrhea agents, as animal feed additive, apply.
In addition, even the present invention finds first within the scope of the additive capacity of nutritional need level, the promotion growth of capric acid zinc is significantly better than same dosage zinc ion donor, as the effect of the compounds such as zinc sulfate, make capric acid zinc can be applicable to effective promotion growth (being less than within the scope of 150ppm zinc ion concentration) of other stages of swine rearing and other animal varieties, and with the zinc sulfate of dosage or other zinc compounds without this effect.
Described capric acid zinc be capric acid with the amount of zinc material than the salt of 2:1.
Described animal is preferably pig, the cultivated animals such as broiler chicken, duck.
Described capric acid zinc (calculating with zinc ion, lower same), its additive capacity in animal feed is 15～2250ppm, preferred dose is 15～450ppm.
Described animal feed is preferably perfect compound feed.
The present invention has proved that by series of experiments capric acid zinc applies the consumption that can reduce nearly 80% zinc oxide in pig feed, also can reach identical production performance, can significantly reduce the application of zinc in animal husbandry, can reduce production costs, reduce the toxic and side effect of high zinc, and reduce environmental pollution, be the zinc compound that possesses unique anti diar rhea and growth promotion advantage.
Therefore, the invention provides capric acid zinc as the application of feed addictive and the application of feeding growth promoter, especially as the unique advantage of the application of the feeding high dose zinc oxide of pig substitute.
The specific embodiment:
Following examples are to further illustrate of the present invention, rather than limitation of the present invention.
Embodiment 1: capric acid zinc synthetic
Under room temperature, in 1L beaker, add 400ml water, open stir add 7.6g NaOH (96%, 0.1818mol), make to dissolve completely, then add 30g capric acid (MW:172.27,0.174mol), after stirring 1h, drip zinc sulfate (MW:287.56,0.091mol) the about 15min of the aqueous solution (26.2g white vitriol+100ml water) adds, and standing 1h after continuation stirring 3h, filters, wash three times, drain, in 50 ℃ of baking ovens, more than dry 8h, obtain capric acid zinc product powder.
Get capric acid zinc product 0.10g with after 100ml0.1M HCl dissolving, by GC method, measure the content of capric acid in solution, with atom absorption method, measure the content of zinc element in solution simultaneously.In result capric acid zinc product, the molecule mol ratio of zinc ion and capric acid is 1:2, and the structural formula of capric acid zinc is suc as formula shown in one.
