Embodiment 1

[0019] A feed additive that is conducive to more litters for pregnant sows, comprising the following components by weight: 99 parts of Chinese herbal medicine and 1 part of vitamin; wherein, the Chinese herbal medicine is composed of the following components by mass percentage: Houttuynia 20 -40%, Radix isatidis 30-40% and Scutellaria 30-40%; the vitamins are composed of vitamin A and vitamin D 3 And vitamin E is composed of 5:1:3 by weight.

[0020] As a preferred embodiment of the embodiment, the Chinese herbal medicine is composed of Houttuynia cordata, Radix isatidis and Scutellaria baicalensis in a weight ratio of 1:1:1.

Embodiment 2

[0022] A preparation method of a feed additive that is conducive to more litters of pregnant sows, including the following steps:

[0023] Step 1. Weigh out the houttuynia cordata, Radix isatidis and Scutellaria baicalensis by weight in Example 1, and cut the houttuynia cordata. After the isatis root and scutellaria are treated with oblique slices, the cut off Houttuynia cordata, Radix isatidis and Scutellaria baicalensis oblique slice materials It is mixed and crushed by an ultra-fine pulverizer. The time taken to pulverize the Chinese herbal medicine into ultra-fine powder is different depending on the part where the Chinese herbal medicine is used. The final crushing mesh is greater than or equal to 300 meshes to prepare the Chinese herbal medicine raw material;

[0024] Step 2: Weigh Vitamin A and Vitamin D in Example 1 by weight 3 And vitamin E, in a three-dimensional mixer, fully mix with the Chinese herbal medicine raw materials prepared in step 1, and mix for 15-20 minutes t...

Embodiment 3

[0030] The Yuanxiang black pig was selected as the experimental breeding pig. The hybrid advantage of this pig is that the meat is fragrant and tender, the marbled meat is more, and the growth rate is slower. It takes about 8-9 months to reach 100 kg. The main color of the whole body is black, and the lean carcass rate is higher.

[0031] Twenty sows with roughly the same parity and mating time were selected in turn, and experimental groups 1, 2, 3 and blank control groups were set up respectively. The product prepared in Example 2 (in which Houttuynia cordata, Radix isatidis, and Scutellaria baicalensis in a weight ratio of 1:1:1) were added to the daily feed of sows at a ratio of 0.5%, 1%, and 1.5%, and 3 were fed month. During this period, the blue ear vaccine will be injected.
