Laying hen feed additive and preparation method thereof

Abstract

The invention discloses a laying hen feed additive and a preparation method thereof. The laying hen feed additive is prepared from the following raw materials: crataegus pinnatifida bunge, allicin, glycyrrhiza uralensis fisch, cinnamon, leonurus japonicus houtt, kudzuvine roots, eclipta prostrate, forsythia suspensa (thunb.) vahl, gardenia jasminoides ellis, calcium hydrogen phosphate, compound vitamin, zinc sulfate, ferrous sulfate, manganese sulfate, potassium iodide, cobalt chloride and corn flour. The prepared laying hen feed additive and a laying hen feed are fed so that the gastrointestinal function and the ovarian function of laying hens can be enhanced and the self immunity is improved; the taste of eggs is obviously improved and the eggs are easy to digest and absorb; the nutritional value and the health effect of the eggs are remarkably enhanced; and when the laying hens are fed by cages, the difference of the quality of the eggs and the quality of domestic eggs is obviously reduced.

Description

technical field [0001] The invention relates to a feed, in particular to a feed additive for laying hens and a preparation method thereof. Background technique [0002] Laying hens refer to the laying hens that are specially raised to lay eggs to supply eggs. Laying eggs are the main source of income for raising laying hens. Different from broiler chickens, the main issue of people raising laying hens is to improve the quality of eggs and maintain or increase egg production, rather than to improve the quality of laying chickens. [0003] At present, with the development of intensive farming industry, the scale of laying hen farming is getting larger and larger. Almost all laying hen breeding companies use compound feed. Due to long-term use of the same raw materials, laying hens have changed the habit of obtaining various foods in a natural state, resulting in eggs that are much less flavorful than traditional native eggs and taste Rough, the nutritional value is also grea...

AI Technical Summary

Problems solved by technology

Almost all laying hen breeding companies use compound feed. Due to long-term use of the same raw materials, laying hens have changed the habit of obtaining various foods in a natural state, resulting in eggs that are much less flavorful than traditional native eggs and taste Rough, the nutritional value is also greatly reduced

The high-density intensive breeding mode also makes the ecological system structure of the breeding environment single, and the resistance of laying hens is weak. Once a disease occurs, it is very easy to cross-infect and spread on a large scale, causing huge economic losses to farmers.

In order to cope with various diseases, farmers have to use a large amount of chemicals and antibiotics. However, the negative effects of these drugs are also very obvious, not only changing the normal composition of the intestinal flora of laying hens, but also leading to the imbalance of the micro-ecological environment in the intestinal tract , also makes the drug remain in the organism, hindering the healthy development of the pollution-free laying hen breeding industry
