Abstract

The invention relates to the field of livestock feed additives, and discloses an additive for feed for weaned pigs as well as a preparation method and an application of the additive. 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 [0001] The invention relates to the field of feed additives for pigs and livestock, in particular to a feed additive for weaned piglets and its preparation method and application. Background technique [0002] False Kungfu ( Piper sarmentosum ), is a plant of the genus Piper, which is widely distributed in India, Vietnam, Indonesia, the Philippines, Papua New Guinea, Malaysia, and Yunnan, Guizhou, Fujian, Tibet, Guangdong, Guangxi and other places in mainland China. Investigations and studies have shown that in the ecological environment system dominated by artificial natural rubber forests in Hainan Province, the distribution and occupancy of pseudo betel plants occupy the largest community of shade-tolerant plant species, and the distribution is relatively wide. [0003] According to reports, various tissues such as the roots, stems, leaves, and fruit ears of the betel have the effect of detoxifying and treating sores. Taking it internally can effectively ...
