Method for preparing formula feed for broiler chicken in early stage

Abstract

The invention provides a method for preparing a formula feed for broiler chicken in the early stage. The formula feed is prepared from the following raw materials in parts by weight: 50-58 percent of corn, 8-12 percent of bran, 25-28 percent of soybean meal, 1-3 percent of DDGS, 0.5-1 percent of plant oil, 1-1.5 percent of shell powder, 0.3-0.6 percent of edible salt and 4-6 percent of mixed batch, wherein the mixed batch comprises astragalus membranaceus, lonicera japonica, hypericum monogynum, coptis chinensis, fructus forsythiae, radix isatidis, cyrtomium fortunei, pine needle meal, codonopsis pilosula and licorice root. The method comprises the following steps of conducting superfine grinding on the traditional Chinese medicinal materials, and adding an ethanol solution to the mixture; boiling the mixture with strong fire, conducting insulation with slow fire, conducting cooling and filtering, and concentrating the filtrate; adding white granulated sugar, and conducting boiling, cooling the mixture to a normal temperature, and inoculating lactobacillus, tea fungus and bifidobacterium; conducting fermentation for 96-120 hours until white fungal mass grows out, concentrating and drying the bacterial liquid at a low temperature, conducting embedding, and conducting granulation and cooling at a high temperature to prepare a granular feed which is the formula feed for broiler chicken in the early stage. The formula feed can be used for supplying amino acids and trace elements for growth of broiler chicken, has the effects of increasing the number of effective microbial communities in intestinal tracts, improving immunity, enhancing disease resistance of chicken bodies and promoting healthy growth of broiler chicken, and has the advantages of high content of viable organisms and no residue.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a preparation method of pre-broiler compound feed. Background technique [0002] With the rapid development of modern society and the continuous improvement of people's living standards, chicken has become an indispensable source of protein in every family's life. The early stage is the most important link in the growth stage of broilers. If this stage is not controlled well, it will Seriously affect the quality of chicken, the survival rate of chicks, the uniformity of slaughter and the total weight of slaughter. In order to increase the growth rate, it is very common to use high-energy methods in the preparation of feed. However, it also brings some problems to broilers, such as indigestion, metabolic disorders, etc., which reduces feed remuneration and causes chicks to die. The farming industry produces huge economic losses. [0003] Feed is extremely critical to th...

Problems solved by technology

In order to increase the growth rate, it is very common to use high-energy methods in the preparation of feed. However, it also brings some problems to broilers, such as indigestion, metabolic disorders, etc., which reduces feed remuneration and causes chicks to die. Aquaculture produces huge economic losses

[0003] Feed is extremely critical to the growth rate of broilers in the early stage. Considering the prevention and control of diseases in the early growth process of broilers in the prior art, some feed additives have appeared, but these product additions are mainly hormone drugs or other Additives, such as antibiotics, hormones, high-copper additives, etc., have solved some problems in the short term, but in fact lead to a sharp decline in chicken quality, and more importantly, they will cause great public harm to human health; in addition, long-term The use of these additives will lead to drug resistance in chickens, and is not conducive to the digestion and absorption of chickens, poor palatability and many other problems
