The present invention provides application of the eucommia leaf extract in preparing the feed addictive for improving female rabbit reproductive performance.The present invention is using New Zealand mother rabbit as research object, study influence of the eucommia leaf extract to its reproductive performance, eucommia leaf extract provided by the invention contains Cortex Eucommiae chlorogenic acid, eucommia bark flavone and eucommia bark polycose, has effects that antibacterial, resisting stress, anti-oxidant, removing free radical, promotes intestinal beneficial bacterium proliferation, improves immunity of organisms and promote heat and prevent miscarriage.The present invention shows that eucommia leaf extract is added in Brood doe daily ration can significantly improve female rabbit reproductive performance, increase economic benefit by experimental studies results.
Description
Technical field
The invention belongs to animal feed additive technical fields, and in particular to eucommia leaf extract is being prepared for improving mother
Application in the feed addictive of rabbit reproductive performance.
Background technology
Rabbit reproductive capacity is that rabbit produces the most important first purpose, and female rabbit reproductive capacity is directly related to the height of production level
Low and economic benefit quality, therefore it is enlarged reproduction and the basis increased economic efficiency to improve reproductive capacity.
From eucommia leaf extract is extracted by natural folium cortex eucommiae, to various pathogens and infection of the upper respiratory tract Causative virus etc.
With significant inhibiting effect.Extracorporeal bacteria inhibitor test shows can be to staphylococcus aureus, beta streptococcus, Escherichia coli
There is good inhibiting effect with typhoid bacillus etc..In addition can also strengthen immunity, remove free radical and other effects.In addition, flavones,
Polysaccharide isoreactivity ingredient, it is different to immune system, internal system, central nervous system, the circulatory system and urinary system
The adjustment effect of degree.
Invention content
The object of the present invention is to provide eucommia leaf extracts to prepare the feed addition for improving female rabbit reproductive performance
Application in agent.Using New Zealand mother rabbit as research object, influence of the research eucommia leaf extract to its reproductive performance is the present invention
Effectiveness of the eucommia leaf extract in terms of improving female rabbit reproductive capacity provides scientific basis.
For achieving the above object, the present invention is achieved by the following scheme：
The present invention provides application of the eucommia leaf extract in preparing the additive for improving female rabbit reproductive performance.
Further：The eucommia leaf extract contains following components：Cortex Eucommiae chlorogenic acid 3%-8%, eucommia bark flavone 8%-
16% and eucommia bark polycose 20%-40%.
Further：The preparation method of the eucommia leaf extract includes the following steps：It takes folium cortex eucommiae to be extracted with water, extracts
55-65 DEG C of temperature, extraction time 2-4h, is then filtered, and filtrate is taken to be concentrated in vacuo to proportion 1.2 at 60 DEG C, through spraying
The eucommia leaf extract is made in drying tower spray drying.
Further：Additive amount of the eucommia leaf extract in female rabbit daily ration is 150g/t-250g/t.
Further：After adding 200g/t eucommia leaf extracts in female rabbit daily ration, the nest production for significantly improving female rabbit is living young
Number.
Further：After adding 200g/t eucommia leaf extracts in female rabbit daily ration, the weigth at birth of female rabbit is significantly improved.
Further：After adding 200g/t eucommia leaf extracts in female rabbit daily ration, the 21 age in days nests of female rabbit are significantly improved
Weight.
Further：After adding 200g/t eucommia leaf extracts in female rabbit daily ration, the 30 age in days nests of female rabbit are significantly improved
Weight.
Further：After adding 200g/t eucommia leaf extracts in female rabbit daily ration, the farrowing rate of female rabbit is significantly improved.
Compared with prior art, it advantages of the present invention and has the technical effect that：Eucommia leaf extract provided by the invention is containing Du
Secondary chlorogenic acid, eucommia bark flavone and eucommia bark polycose have antibacterial, resisting stress, anti-oxidant, remove free radical, promote intestinal beneficial bacterium
Proliferation improves immunity of organisms, the effect of promoting heat and prevent miscarriage.The present invention is shown by experimental studies results in Reproductive Female
Eucommia leaf extract is added in rabbit daily ration can significantly improve female rabbit reproductive performance, increase economic benefit.
Specific implementation mode
Further detailed description is done to technical scheme of the present invention with reference to specific embodiment.
Embodiment 1
1 material and method
Selection, grouping and the experimental period of 1.1 experiment rabbits
Select age and weight close, the first-born is normal, the New Zealand mother rabbit 120 of genital tract health after childbirth, random point
It is rented for control group and experiment, every group 60, every group of 3 repetitions, it is each to repeat 20.Control group fed basal diet, test group
The same basal diet of feeding addition 200g/t eucommia leaf extracts.Experiment is since after the first-born childbirth, the wean of the second fetus rabbit
When terminate, 105 days experimental periods.
1.2 test periods, place and trial target
Test period：2 months 21-June 5 in 2014,105 days experimental periods.
Test site：Sichuan Agricultural University's teaching and scientific research warren.
The preparation method of the eucommia leaf extract includes the following steps：Folium cortex eucommiae is taken to be extracted with water, Extracting temperature 55-65
DEG C, then extraction time 2-4h is filtered, filtrate is taken (to select this temperature extraction, it is possible to reduce the damage of chlorogenic acid at 60 DEG C
Lose, and recovery rate highest) be concentrated in vacuo to proportion 1.2 (be concentrated to the solution of this proportion, the time used in spray drying is most short, because
For chlorogenic acid pyrolytic, the spray drying used time is short, and chlorogenic acid moment spray drying is not lost, and energy saving) spray-dried tower
The eucommia leaf extract is made in spray drying.
Eucommia leaf extract obtained contains：Chlorogenic acid 5%, eucommia bark polycose 20%, eucommia bark flavone 8%, by quality ratio.
1.3 experimental design
It is designed using single-factor random experiment, the feed of feeding is identical with trophic level, control group fed basal diet, examination
Test a group addition 200g/t eucommia leaf extracts.
1.4 Diet Formulas and trophic level
1 Diet Formula of table and trophic level
1.5 feeding managements are measured with experiment
Every morning 8 cleanings, 9 points start to feed.Free choice feeding and free water.
Start to feed after the childbirth of the first tire of female rabbit, the wean of 30 age in days of young rabbit, postweaning estrus breeding.Using spontaneous estrus,
Human assistance is bred.The rabbit of heat breeds in 15 days after wean, still continues to breed in 15 days if returning feelings after breeding, after 15 days not
