Feed additive for improving lactation performance of lactating sows and preparation method thereof

Abstract

The invention discloses a feed additive for improving the lactation performance of lactating sows and a preparation method thereof. The feed additive consists of the following components in part by weight: 50 to 60 parts of cowherb seed, 5 to 8 parts of dandelion, 8 to 10 parts of atractylis, 5 to 8 parts of akebia stem, 5 parts of astragalus, 5 pars of liquoric root, and the balance of zeolite powders. After being mixed, cowherb seed, dandelion, atractylis, akebia stem, astragalus and liquoric root are subjected to cell-level fine grinding to enable the grain diameter of the mixture to be 25-40 microns. Then zeolite powders are added in the mixture to be uniformly mixed. The feed additive for improving the lactation performance of the lactating sows has the advantages of obvious improvement on the lactation performance of the lactating sows (lactation yield and lactic quality), low addition volume, good effect, no residue, and no toxic or side effects.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving the lactation performance of lactating sows, with Wangbuliu as the main body. Background technique [0002] Breast milk is the main source of nutrients for piglets from birth to weaning, and the quality and quantity of breast milk determine the survival rate and growth rate of piglets. The low lactation ability of sows can directly lead to nutritional deficiencies, growth retardation, and increased mortality in piglets, affect piglets' weaning weight, aggravate piglets' weaning stress, and affect subsequent growth and development. Therefore, the basic goal of the sow during lactation is to ensure that the sow takes in sufficient nutrients, secretes sufficient milk, and maintains a proper body condition, so that the sow can go into estrus and ovulate normally after the piglets are weaned, and enter the next reproductive cycle. According to data, compared with the l...

Problems solved by technology

Since the use of Chinese herbal medicines is still based on experience and traditional formulas, coupled with the backwardness of traditional research methods and production techniques, Chinese herbal medicines in China have not been well utilized and developed, especially in the feed additive industry. Widespread, and its effectiveness questioned

There are several major problems restricting the large-scale application of Chinese herbal medicine feed additives: (1) High addition ratio: because the traditional method uses ordinary crushing, the medicinal effect in plants cannot be quickly absorbed and utilized by animals, so people often use high additions. The addition of 0.5% to 5% will lead to higher costs, and the high addition will lead to poor palatability of the feed, and animals will eat less or refuse to eat; (2) slow drug effect and serious waste: traditional Chinese medicine works through the overall effect , it can’t reach the level of western medicine in treating the symptoms at all, because the plant directly enters the gastrointestinal tract, and the active ingredients in the plant can only be finally absorbed and utilized by animals after passing through the plant cell wall

As confirmed by the Novelty Check Workstation (Z09) of the Ministry of Education, there is no report on feed additives that improve the lactation performance of lactating sows, with Wang Buliu as the main ingredient
