A composite preparation for reducing a diarrhea rate of weaned piglets and a preparing method thereof

Abstract

A composite preparation for reducing a diarrhea rate of weaned piglets is disclosed. The composite preparation is prepared by mixing an oligosaccharide-acidifier solution and a probiotic fermentation liquor according to a volume ratio of 1:(3-5). Each mL of the oligosaccharide-acidifier solution contains 2500-3500 mug of oxalic acid, 30-60 mug of tartaric acid, 50-100 mug of malic acid, 4000-5500 mug of lactic acid, 2500-4000 mug of citric acid, 0.05-0.2 g of glucose, 0.05-0.1 g of isomaltooligosaccharide, 0.02-0.06 g of fructooligosaccharide and 0.08-0.15 g of chitosan oligosaccharide. The probiotic fermentation liquor is prepared by mixing a mixed fermentation liquor of lactobacillus plantarum and pediococcus pentosaceus and a clostridium butyricum fermentation liquor according to a volume ratio of (2-4):1. A preparing method of the composite preparation is also disclosed. The composite preparation reduces the diarrhea rate of weaned piglets, reduces the death rate of piglets, and boosts productive performance and immunity of piglets.

Description

technical field [0001] The invention relates to a compound preparation for reducing the diarrhea rate of weaned piglets and a preparation method thereof. Background technique [0002] In recent years, my country's pig industry has developed very rapidly, and the management and scale of breeding have been improved. With the improvement of pig production technology, some countries and regions with developed pig farming have gradually popularized early weaning technology for piglets, but premature weaning will cause nutritional, environmental and psychological stress in piglets, resulting in poor feed intake reduction, stunted growth, weight loss, diarrhea, and even death. According to reports, piglets below 30kg have an annual diarrhea incidence rate of 46.5% and a mortality rate of 10.3%. Therefore, how to prevent and treat diarrhea in weaned piglets has become one of the urgent tasks of the current pig industry. [0003] So far, in the prevention and treatment of weaned p...

Problems solved by technology

[0003] So far, in the prevention and treatment of weaned piglet diarrhea in China, drugs such as antibiotics are directly injected or added to the feed. With the emergence of a large number of drug-resistant strains, it is often found that the existing chemical drugs are not effective in controlling diarrhea, and these drugs Extensive use of large-scale use may easily cause drug residues in animal products, which will accumulate in the human body and seriously threaten human health; although vaccine immunization can increase the antibody content in sow milk, the duration of the antibody is short, and it is not enough to protect piglets throughout the growth stage Diarrhea does not occur, and the serotype of Escherichia coli is complex and constantly changing, even if the piglets are immunized, there is little effect; Chinese herbal medicines are slow in efficacy, large in dosage, and poor in palatability, which limits their application in weaned piglet diets; high copper, high Trace elements such as zinc are also used, but they are prone to residues, large pollution, and easy to cause heavy metal poisoning; enzyme preparations are also used, but the action point is too single to solve the diarrhea caused by intestinal flora imbalance
