Sow feed additive with lactation promoting function as well as feed and application thereof

Abstract

The invention provides a sow feed additive with a lactation promoting function, as well as a feed containing the additive and application of the feed. The additive consists of the following components in parts by weight: 600 to 800 parts of pilose asiabell root, 600 to 800 parts of astragalus root, 100 to 200 parts of angelica dahurica, 100 to 200 parts of dwarf lilyturf root, 100 to 200 parts of ricepaper pith, 200 to 300 parts of pangolin and 100 to 200 parts of platycodon grandiflorum. According to the physiological characteristics of lactating sows and the compatible regulation, the feed can be used for promoting the postpartum recovery of the sows and promoting lactation and is low in feeding quantity, 0.2 to 0.5 gram of the feed is fed for 100 kilograms of sow every day, and the milk yield is obviously promoted after two days.

technical field [0001] The invention relates to a feed additive, in particular to a sow feed additive with lactating function, and also to feed containing the feed additive and its application. Background technique [0002] Pigs are mammals, sows get their name because they can secrete milk through mammary glands after giving birth. In order to improve economic efficiency, the farrowing weight of sows is often increased by feeding farrowing-promoting feeds. However, too many litters lead to insufficient milk supply of sows, which affects the quality of piglets, mainly manifested as slow growth and low immunity. Therefore, providing sufficient sow milk for piglets is a technical problem to be solved urgently. In the prior art, chemical additives or Chinese herbal medicines are mainly used to promote lactation. Chemical additives promote lactation quickly, but have certain side effects, which affect the health of sows. The Chinese patent No. 200910103691.7 discloses a Chine...
