Problems solved by technology

However, in broiler chicken farming, in order to shorten the breeding cycle, reduce mortality, and reduce costs, most chicken farmers will choose to add antibiotics and other drugs to the feed, resulting in the emergence of drug resistance or drug resistance in chickens, and the endogenous Sexual infection, reduction of chicken immune function, decline of disease resistance, antibiotic residues in chicken, etc.

Embodiment 1

[0029] Taking 1 ton of broiler feed additive as an example, the amount of semi-finished Bacillus licheniformis used is 35 billion / g, the amount of semi-finished Bacillus subtilis is 35 billion / g, and the amount of semi-finished Enterococcus faecium is 100 billion / g. The amount of coccus semi-finished product is 100 billion / g.

[0030] (1) Weigh a certain amount of Enterococcus faecium and Streptococcus faecalis and mix evenly. The weighing amount is 5 billion / g as an example, and 50kg should be weighed respectively;

[0031] (2) Then weigh a certain amount of Bacillus licheniformis and Bacillus subtilis, mix them evenly, take 10 billion / g as an example, and weigh 1000*100 / 350=285.7kg;

[0032] (3) Weigh and add a certain amount of xylanase and polysaccharide, mix and mix well, the amount to be weighed is 10% as an example, weigh 100kg;

[0033] (4) The balance is talcum powder, after mixing thoroughly, pack it separately. The weighing amount is 1000-285.7-285.7-50-50-100-100...

Embodiment 2

[0035] Taking 500 kg of broiler feed additives as an example, add 44.44 kg of Bacillus licheniformis 90 billion / g, add 50 kg of Bacillus subtilis 100 billion / g, add 16.67 kg of Enterococcus faecium 150 billion / g, add 12.5 kg of Streptococcus faecalis 200 billion / g kg, 100kg of yeast cell wall polysaccharide, 50kg of xylanase, and 226.39kg of talcum powder were added. In the obtained additive, Bacillus licheniformis 8 billion / g, Bacillus subtilis 10 billion / g, Enterococcus faecium 5 billion / g, and Streptococcus faecalis 5 billion / g. It can be applied to broiler chickens aged 3 to 5 weeks.

Embodiment 3

[0037] Take 1 ton of broiler feed additives as an example, add 136.84kg of Bacillus licheniformis 95 billion / g, add 83.33kg of Bacillus subtilis 120 billion / g, add 53.33kg of Enterococcus faecium 150 billion / g, add 200 billion / g of Streptococcus faecalis 20kg, 250kg of yeast cell wall polysaccharide, 50kg of xylanase, and 406.5kg of talcum powder. Among the obtained additives, Bacillus licheniformis 13 billion / g, Bacillus subtilis 10 billion / g; Enterococcus faecium 8 billion / g; Streptococcus faecalis 4 billion / g. It is applied to broiler chickens aged 1 to 3 weeks.

Abstract

Belonging to the technical field of feed additive formulation design, the invention specifically relates to a novel green broiler chicken feed additive, which has a formula composed of a probiotic composition, xylanase, polysaccharide and a carrier. Application of the feed additive in broiler chicken breeding can obviously enhance the daily gain of broiler chickens, raise the utilization efficiency of broiler chickens on daily ration, reduce the feed meat ratio, improve the growth performance of broiler chickens, and is free of drug resistance, drug residual and other problems, so that the chicken meat quality is good.

Description

technical field [0001] The invention belongs to the technical field of formula design of feed additives, in particular to broiler feed additives and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for meat is increasing day by day, and the voice of green food is getting higher and higher. However, in broiler chicken farming, in order to shorten the breeding cycle, reduce mortality, and reduce costs, most chicken farmers will choose to add antibiotics and other drugs to the feed, resulting in the emergence of drug resistance or drug resistance in chickens, and the endogenous Sexual infection, reduction of chicken immune function, decline of disease resistance, antibiotic residues in chicken, etc. Therefore, the emergence of new antibiotic substitutes has become an inevitable trend-probiotics. At present, the breeding cycle of broilers is generally about 38-45 days. If the breeding cyc...
