Novel poultry micro-ecological preparation and preparation method thereof

Abstract

The invention relates to a novel poultry micro-ecological preparation and a preparation method of the novel poultry micro-ecological preparation. The preparation comprises following components in part by weight: 0.8-3.5 parts of vitamin A, 0.2-0.8 part of vitamin D, 2-8 parts of vitamin E, 0.2-1.2 parts of vitamin K, 0.1-0.9 part of vitamin B1, 0.2-0.8 part of vitamin B2, 0.1-0.7 part of vitamin B6, 0.08-0.5 part of vitamin B12, 2-5 parts of nicotinamide, 0.8-3.5 parts of calcium pantothenate, 0.02-0.4 part of folic acid, 0.2-1.2 parts of biotin, 0.02-2 parts of vitamin C, 1.3-32 parts of enterococcus faecium, 27-155 parts of bacillus subtilis, 75-210 parts of oligosaccharide, 150-400 parts of pine needle meal and 400-600 parts of bentonite. The novel poultry micro-ecological preparation can improve daily gain, feed intake, feed conversation efficiency of young poultry, reduces death and culling rate of the young poultry, and improves reproductive performance of breeding poultry, laying rate, fertilization rate of hatching eggs, hatching rate, and healthy rate of the young poultry. According to the invention, as double-layer shallow coating is performed to enterococcus faecium, the stress resistance of enterococcus faecium is improved.

Description

Technical field [0001] The patent of the present invention relates to a preparation method of probiotics, especially a preparation method of a novel probiotics for poultry. Background technique [0002] After decades of continuous development of poultry farming in my country, the amount of poultry breeding has been increasing, and the output has also been rising. In 2011, the total output of poultry meat exceeded 16 million tons, and the total output of poultry eggs was 28.11 million tons, an increase of 1.8% over the previous year. However, even though my country is the world's second largest producer of poultry meat next to the United States, and poultry egg production accounts for more than 40% of the world's total output, my country's poultry breeding level is still in a relatively primitive state. Our poultry meat consumption is relatively low. In 2011, the per capita consumption of chicken meat was only 12kg, far lower than the 42.2kg in the United States, 40.6kg in S...

AI Technical Summary

Problems solved by technology

[0008] The main problems in the application of existing microecological preparations are: ① live bacteria preparations are easily inactivated during feed processing and transportation; , it is difficult to have a sufficient amount to reach the intestinal tract or settle in the intestinal tract to play a role; ③The growth rate is slow, and it is difficult to be in a dominant position in the competition with harmful intestinal microorganisms; ④The strain is single, lack of compatibility research, and the effect is one-sided

These three types of Lactobacillus have strong tolerance to the environment in the digestive tract and have good acid production effects, but the strains are single and the effects are similar, so they cannot complement each other and have no obvious effect on improving feed utilization.

Patent 201010517542.8 is a microecological preparation composed of live butyric acid bacteria and an acceptable carrier. Butyric acid bacteria can produce butyric acid, enzymes and vitamins, and has a good ability to promote the digestion and absorption of nutrients, but butyric acid bacteria are resistant to bile salts in the intestinal tract. The tolerance of butyric acid bacteria is not yet clear, so the activity of butyric acid bacteria in the digestive tract remains to be studied
