Novel poultry micro-ecological preparation and preparation method thereof

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.
