Piper sarmentosum extract and carriers are added to the additive, the prepared feed additive can be directly added to the feed for the weaned pigs, accordingly, the growth performance of the weaned pigs can be improved, the antioxidation, anti-inflammatory and immunity ability of the weaned pigs is enhanced, the application is convenient, and the effect is remarkable. With adding of the additive for the feed for the weaned pigs, the working difficulty of feeding of the weaned pigs is reduced, and the feeding cost is saved.
Description
Technical field
The present invention relates to pig domestic animal feed additive field, refer to a kind of feed additive for weaning piglet and its preparation method and application especially.
Background technology
Jia Betel (
piper sarmentosum), be the plant of Piperaceae Piper, be distributed widely in the ground such as Yunnan, Guizhou, Fujian, Tibet, Guangdong, Guangxi of India, Vietnam, Indonesia, Philippine, Papua New Guinea, Malaysia and China's Mainland.Investigation shows, in Hainan Province based in the Eco-Environment System of artificial natural rubber woods, false Betel plant distributions occupancy volume, in occupation of the maximum group in shade plants kind, distributes comparatively extensive.
It is reported that each tissues such as ， Jia Betel root, stem, leaf, fruit ear have detoxification sore treatment effect, take orally and effectively can treat the illnesss such as abdominal distension, enteritis, diarrhea, rheumatalgia, external application can treat hemorrhage, become silted up blue or green and the pernio etc. that wound causes.Recent study shows, Folium Piperis sarmentosi water-soluble extractive has anti-inflammatory activity, and the amides compound in its extract has significantly anti-oxidant, resistive connection nuclearity effect.
Weaned piglet is a vital stage in feeding piglet process.In wean process, owing to progressively adding feed in food, the incidence of the diseases such as grice diarrhoea increases greatly, and growth performance reduces greatly, has had a strong impact on growing of piglet.Therefore, improve weanling pig intestinal immunity for early-weaned piglets spend smoothly early weaning close most important.
Summary of the invention
The present invention proposes a kind of feed additive for weaning piglet and its preparation method and application, there is the effect improving weanling pig immunity, improve piglet growth performance.
Technical scheme of the present invention is achieved in that
A kind of feed additive for weaning piglet, comprises following component: Jia Betel extract and carrier.
Further, described Jia Betel extract formulation, comprises component: Jia Betel extract 1-3 part of following parts by weight, carrier 1-3 part.
Further, described carrier is silica or calcium carbonate.
Further, described Jia Betel extract is made as dry in the shade Folium Piperis sarmentosi sheet supercritical carbon dioxide extraction method or soxhlet extraction and obtains Jia Betel extract.
The preparation method of described feed additive for weaning piglet, comprises the following steps:
Get formula ratio Jia Betel extract and carrier, mix, obtain feed additive for weaning piglet of the present invention.
Described feed additive for weaning piglet improves the application on the feed of Growth Performance of Weaning Piglets in preparation.
