preparation example Construction

[0042] In an optional embodiment, the preparation method includes: drying Liushenqu, Muxiang, Magnolia officinalis, Shijunzi, Suanzaoren, raw hawthorn, chicken's gold, and Codonopsis pilosula in an oven at 65-85°C, and drying the The dried product is pulverized, and the pulverized product is passed through a 380-420 mesh sieve and then mixed with gamma-aminobutyric acid, tryptophan and yeast nucleic acid according to the parts by weight.

[0043] In addition, the embodiment of the present invention also provides the application of the feed additive for increasing the blood IGF-I concentration and promoting growth of weaned piglets as described in the foregoing embodiments in feeding weaned piglets.

[0044] In an optional embodiment, the feed additive is added into a basal ration to feed weaned piglets, and the addition ratio of the feed additive in the basal ration is 0.3wt%-0.8wt%. It should be noted that the basal diet is a prior art, used for raising weaned piglets, and is...

Embodiment 1

[0047] The present embodiment provides a kind of feed additive that improves blood IGF-1 concentration of weaned piglets and promotes growth, according to parts by weight, the raw material of described feed additive is made up of following components:

[0048] Composed of 5 parts of Liushenqu, 4 parts of Muxiang, 2 parts of Magnolia officinalis, 6 parts of Shijunzi, 5 parts of Suanzaoren, 5 parts of Raw Hawthorn, 5 parts of Chicken Neijin and 6 parts of Dangshen.

Embodiment 2

[0050] This embodiment provides a kind of feed additive that improves blood IGF-1 concentration and growth promotion of weaned piglets, and it is roughly the same as the feed additive in Example 1, the difference is:

[0051] The feed additive also includes 10 parts of gamma-aminobutyric acid.

Abstract

The invention discloses a feed additive for increasing blood IGF-I concentration and promoting growth of weaned piglets, and a preparation method and application of the feed additive. The feed additive comprises massa medicata fermentata, banksia rose, mangnolia officinalis, rangoon creeper fruits, semen ziziphi spinosae, raw hawthorn, membranes of chicken gizzards and dangshen roots. Weaning stress of piglets can be effectively improved, and the problems of growth retardation and physical decline of piglets caused by weaning can be avoided and reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed additive for increasing blood IGF-I concentration and promoting growth of weaned piglets, and a preparation method and application thereof. Background technique [0002] When piglets are weaned, weaning stress will be induced, which will easily lead to a decline in physical fitness and affect growth and development. Existing piglet weaning methods include a one-time weaning method, which means that when the piglet reaches the weaning age, the mother and piglet are separated at one time to achieve the purpose of weaning. Although this weaning method is simple and convenient, and can promote rapid estrus of sows after weaning, the disadvantage is that after weaning suddenly, it will induce weaning stress and affect the growth and development of piglets. [0003] How to effectively avoid or reduce piglet weaning stress is one of the urgent problems to be solved today. Content...
