Probiotic composition for livestock and poultry

Abstract

A probiotic composition used for livestock and poultry can overcome micro dysbiosis, decreased disease resistance and production performance of livestock and poultry, and the side effects like drug resistance and drug residue which are caused by using antibiotics and chemical drugs in a large amount for a long time in feed. The probiotic composition contains effective components with the following weight portions: 3 to 10 portions of Lactobacillus acidophilus, 2 to 6 portions of yeast, 1 to 8 portions of bacillus subtilis, 3 to 8 portions of Bifidobacterium longum, 2 to 5 portions of bacillus licheniformis, and 1 to 4 portions of aspergillus oryzae and vector. The weight ratio of probiotic to vector is 2:7, and the content of the active compositions are that: greater than or equal to 8 billion / g of Lactobacillus acidophilus, greater than or equal to 7 billion / g of yeast, greater than or equal to 9 billion / g of bacillus subtilis, greater than or equal to 9 billion / g of Bifidobacterium longum, greater than or equal to 6 billion / g of bacillus licheniformis and greater than or equal to 6 billion / g of aspergillus oryzae, respectively. The probiotic composition of the invention can reduce lead content in animal products, achieve the purpose of producing green and harmless animal products, promote growth and development of animal and increase animal digestibility to feed.

Description

technical field [0001] The invention relates to a probiotic composition added to livestock and poultry rations, which can obviously improve the growth performance of livestock and poultry and produce green and pollution-free animal products. technical background [0002] Antibiotics have been used as veterinary drugs and feed additives for many years due to their advantages such as broad antibacterial spectrum. However, the long-term and large-scale use of antibiotics has led to the imbalance of normal flora in the digestive tract of livestock and poultry, resulting in side effects such as drug resistance, decreased immune function, and drug residues in livestock products, resulting in a decrease in the quality of livestock and poultry products, which seriously restricts the productivity of livestock and poultry. It poses a greater threat to food safety. For this reason, researchers at home and abroad have begun to develop and apply probiotics that are non-toxic, non-pollut...
