Feed additive for increasing yield of poultry and preparation method of feed additive

Abstract

The invention discloses a feed additive for poultry yield increase and a preparation method thereof, and belongs to the field of feed additives, and the feed additive is prepared from the following raw materials in parts by weight: 10-13 parts of polygonum cuspidatum, 8-11 parts of salvia miltiorrhiza, 6-9 parts of semen cuscutae, 6-9 parts of angelica sinensis, 6-9 parts of ligusticum wallichii, 6-9 parts of oyster, 5-8 parts of sanguisorba officinalis, 6-9 parts of cistanche, 2-5 parts of clove, 5-8 parts of radix paeoniae alba, 2-5 parts of eucommia ulmoides, 4-7 parts of bighead atractylodes rhizome, 3-5 parts of glossy privet fruit, 5-8 parts of astragalus membranaceus, 1-4 parts of malt, 2-5 parts of hawthorn and 2-5 parts of dendrobe. The preparation method comprises the following steps: weighing the raw materials in parts by weight, crushing and sieving to obtain mixed medicine powder; adding a solution into the mixed medicine powder for extraction, and collecting filtrate; and carrying out reduced pressure distillation on the filtrate, concentrating and drying. The additive amount of the feed additive disclosed by the invention in the feed is 0.5-1.5%, and the feed additive can be directly used. The feed can improve the egg laying performance of poultry and promote yield increase.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a feed additive for increasing production of poultry and a preparation method thereof. Background technique [0002] With the gradual scale and intensification of the breeding industry, a series of problems will also appear in the breeding process for poultry. A considerable part has not yet perfected the biological safety system, and the breeding environment is relatively harsh. Infestation, maternal diseases, immunosuppressive diseases, and the application of inferior vaccines seriously affect the egg production rate of poultry and further affect the economic benefits of poultry farming. At present, most of the feed additives are antibiotics, chemical synthetic drugs, vitamins, trace elements and hormones, etc. Poultry fed with these additives generally have drug residues and side effects. Therefore, in the process of raising poultry, it is necessary to solve the problem of how t...
