Abstract

The invention provides a lactic acid bacteria powder for suckling pigs as well as a preparation method and a using method thereof and belongs to the technical field of microorganism feed additives. The adopted lactic acid bacteria comprise one or more of enterococcus faecalis, enterococcus faecium, pediococcus acidilactici, streptococcus thermophiles, lactobacillus acidophilus, lactobacillus plantarum and lactobacillus casei. The active viable count is 50-1000 hundred million / gram and the water content is 4-8%. When the lactic acid bacteria are ingested by newborn suckling pigs through the way spraying the lactic acid bacteria powder obtained by using the preparation method in mouth cavities of the newborn suckling pigs or on nipples of sows, the death rate of the suckling pigs is reduced; the rate of sick pigs with red or white dysentery is reduced; the weight is increased; the suckling pigs are vivacious and bright in fur; the special effects of the lactic acid bacteria are fully developed.

Description

technical field [0001] The invention belongs to the technical field of microbial feed additives, in particular to a lactic acid bacteria powder for suckling pigs and a preparation method and application method thereof. Background technique [0002] Since the 20th century, a variety of antibiotics and hormones have been widely used as feed additives. Although they have played an indispensable role in livestock and poultry production, disease prevention and promotion of animal growth, due to long-term use and even abuse, the use of antibiotics There are more and more problems in the use, mainly in: drug residues and toxicity; large-scale use of broad-spectrum antibiotics in feeding livestock causes rapid growth of bacterial resistance; long-term use of antibiotics disrupts the microbial community in the microbial system of livestock and poultry Micro-ecological balance, leading to digestive disorders, causing various digestive tract diseases; reducing the immune function of an...
