Abstract

The present invention provides one kind of heat stress resisting feed additive, which is mixture of mint oil coated in beta-cyclodextrin, tea polyphenol and dried old orange peel in the weight proportion among the mint oil, tea polyphenol and dried old orange peel of 1-4 to 4-8 to 100. The feed additive made with natural materials may be applied regularly safely. Adding the feed additive in 0.5-1.0 % into the mixed feed for pig and chicken can lower the rectal temperature of heat stress animal and lower the contents of serum creatine phosphokinase, serum cortisol and serum lactic dehydrogenase, so as to increase feed intake. The heat stress resisting feed additive can raise the productivity of animal and has high marketability.

Description

A kind of anti-heat stress feed additive and application thereof
(1) technical field
The present invention relates to a kind of anti-heat stress feed additive that improves livestock and poultry production performance in thermal environment.
(2) background technology
Heat stress is meant the summation of nonspecific physiological reaction that any requirement that the body that is in the high ambient temperature proposes body thermal environment is done.The not only organism physiology function disorder that changes of livestock and poultry under the heat stress environment, feed intake descends, and also will cause fodder energy to distribute in vivo with efficient and change, and causes degradation under the production performance.Along with developing rapidly of intensification high-density rearing mode, breeding enterprise more and more an urgent demand is alleviated the environmental pressure that summer high temperature brings aquaculture.
Under general working condition, it is unpractical the environment temperatures of livestock and poultry such as being controlled in the hot-zone.Because by strengthening the pig house thermal and insulating performance and adopting environmental control equipment uneconomical economically.In production reality, the temperature controlling range of pig house generally produces obviously influence and is advisable being unlikely to the lives of livestock and poultry and producing.Therefore nutrition regulation must become the important means of control heat stress.State such as Japan and the United States, English scholar has carried out the research in this field 50~seventies at twentieth century.The Chinese scholar starting is late, sets foot in this field from the beginning of the eighties, seeks heat stress and changes to the regularity that animal brings, and discloses the influence of thermal environment to the pig productivity, and the feed addictive (thing) that heat stress influences is alleviated in development.
The anti-heat stress additive (thing) of report is more at present, and vitamin C, vitamin E, electrolyte balance agent, acid supplement, trace element chromium, medicine and biologic product etc. are arranged.But these anti-heat stress additives (thing), also do not have a kind ofly can really possess safety, efficient,, what finally can have be difficult to estimate by the body utilization as VC easy oxidized inefficacy in the interpolation process, and some anti-heat stress medicines use for a long time, are difficult to avoid occurring toxic and side effect and medicament residue.Therefore, natural, the anti-heat stress additive for farm animal feed will have good market prospects efficiently.
(3) summary of the invention
The present invention promptly is for a kind of novel safely and efficiently anti-heat stress feed additive is provided, and purpose is to strengthen the anti-oxidation function of livestock and poultry and improves immunologic function of livestock and birds, regulates the livestock and poultry homeostasis.
For reaching goal of the invention the technical solution used in the present invention be:
Mainly beta-schardinger dextrin-encrusting substance, Tea Polyphenols and the dried orange peel by the peppermint essential oil mixes, and the beta-schardinger dextrin-encrusting substance quality of described peppermint essential oil is in the peppermint essential oil, with the ratio of the quality of Tea Polyphenols, dried orange peel be 1~4: 4~8: 100.
The peppermint essential oil of indication of the present invention is to be made with extra care through operations such as dehydration, distillation, impurity elimination, modulation by the natural raw peppermint oil of high-quality to form; total menthol content (ester value is measured after the acetylation) 78.0~80.0%; L-menthol content 〉=70.0%; contain ester amount (in menthyl acetate) 1.5~3.5%; contain ketone amount (in menthones) 8.5~15.5%, quality meets the relevant index of national GB/T12652-2002 standard.Peppermint essential oil and beta-schardinger dextrin-ratio are 1mL: 6~10g in the beta-schardinger dextrin-encrusting substance of described peppermint essential oil.
The beta-schardinger dextrin-encrusting substance of described peppermint essential oil prepares as follows: the commercial peppermint essential oil and the core ratio of beta-schardinger dextrin-add the ratio of beta-schardinger dextrin-6~10g in every 1ml peppermint essential oil, adding water, to make solid concentration be 18~22%, adding white carbon black makes water content 50~55%, by high pressure homogenizer homogeneous (homogenization pressure 35~45MPa), form uniform and stable material liquid behind the homogeneous at 60~100 ℃ of following fluidized bed dryings, dry about 2h, make water content 8.0~9.5%, promptly get the beta-schardinger dextrin-encrusting substance of described peppermint essential oil.
Described fluidized bed process parameter is as follows:
Temperature control: EAT: 100 ℃; Temperature of charge: 60 ℃; Leaving air temp: 40 ℃;
Whirlwind outlet: 90~95 ℃.
Pressure control: blower export: 4500Pa; Hot-blast stove outlet: 1000~2000Pa; Dry
Tower outlet: 0~150Pa; Whirlwind outlet :-250Pa; The bag hose outlet:
-360Pa。
Described Tea Polyphenols is carried for oneself or is commercial, and catechin content accounts for 60%~80% of Tea Polyphenols total amount.
Described dried orange peel is commercial, and moisture is below 8% during application, and grinding particle size is at 60~80 orders.
Peppermint essential oil (using encrusting substance, with the peppermint essence oil content meter), Tea Polyphenols and three kinds of materials of dried orange peel are made up with 1: 4: 100 mass ratio, and above-mentioned compound is mixed, obtain a kind of novel anti-heat stress feed additive.
Show after deliberation: the peppermint essential oil is used in pig feed by the back by the present technique bag can give full play to the effect of peppermint essential oil, after the peppermint essential oil through wrapping quilt and Tea Polyphenols, dried orange peel make up in certain proportion, has significantly positive combined effect.
Described anti-heat stress feed additive is mainly used in the livestock and poultry anti-heat stress ability that improves.
Described being applied as: described anti-heat stress feed additive is accounted for livestock and poultry by its quality make an addition in the feed, feed after evenly mixing with 0.5~1.0% of mixed feed quality.
Concrete, described livestock and poultry are pig, described being applied as: described anti-heat stress feed additive is accounted for 0.5~1.0% of pig's mixed feed quality by its quality make an addition in the feed, feed after evenly mixing.
Compatibility material peppermint essential oil of the present invention, Tea Polyphenols, dried orange peel all are natural materials, long-term devoid of risk safe in utilization.Interpolation 0.5~1.0% novel anti-heat stress feed additive of the present invention in pig, chicken mixed feed can obviously reduce the rectal temperature of heat stress pig, reduces the content of serum creatine phosphokinase, serum cortisol, serum lactic dehydrogenase (SLDH).Novel anti-heat stress feed additive of the present invention is brought into play its anti-stress effect by adjustment livestock and poultry serum part hormone-content, change serum part biochemical indicator, raising feed intake.Use novel anti-heat stress feed additive of the present invention, can significantly improve the production performance of pig in heat stress environment, have remarkable economic efficiency and social benefit, market prospects are wide.
