In modern livestock farming, biosecurity plays a leading role in every factor of safe product production. Maintaining a biosecure farm environment helps prevent the risk of dangerous infectious diseases related to safe food production. All countries exporting livestock products, especially fresh products, must have an origin certified as a biosecure production zone, and Vietnam is also moving toward biosecure livestock farming criteria.
Today, in livestock and poultry farming, digestive health is given top priority and is a concern worldwide. Digestive health depends on many factors, among which the balance of beneficial gut microbiota is key. Only a healthy digestive system can properly metabolize and absorb nutrients from an ideal diet. The number of microorganisms present in an animal's digestive system varies by species and by segment of the digestive tract (stomach, small intestine, duodenum…); the range of microbial strains can also vary, reaching 400–500 different strains, with microbial density fluctuating strongly from 10^1 to 10^12 CFU/ml in digestive fluid. The symbiosis of many microbial strains in the digestive tract helps create an open ecosystem and a balance within the microbial population.
This is the first pilot production project to use native LAB and yeast sources for industrial-scale production of biological products applied in domestic livestock farming. The native LAB source was obtained from the findings of the study "Evaluation of native Lactic bacteria gene sources oriented toward application in food and animal feed," which were mainly isolated from native fresh plant sources, animal digestive systems, and fermented plant and animal sources. Besides their Bacteriocin-producing properties, these lactic strains were also highly regarded for other outstanding characteristics, such as exopolysaccharide production and biofilm-forming ability among LAB strains. Probiotic preparations from L. acidophilus and S. boulardii yeast with clearly traceable strain origins are new products from this research topic. Building on the inherited research results, this pilot production project will develop a formulation process for combining the strains, thereby creating Probiotic biological products for the livestock industry, ensuring safety and reducing livestock production costs.
Nam Viet JSC operates a farm with an area of nearly 100 hectares, with a modern automated farm system using fully imported grandparent-stock pigs and equipment from Denmark. The Nam Viet Research and Technology Application Center has taken on and carried out the project's work, conducting pilot production of Probiotic yeast for use across the company's entire farm system. Through batching, monitoring, and comparative trial rearing, the project has achieved a number of very good results, such as healthier livestock, reduced feed consumption, and reduced veterinary medicine costs. Once the project is completed, and the product has been tested and evaluated through real-world usage results and approved by the scientific evaluation council, the company will complete all procedures in accordance with state regulations to produce and roll out the product widely at an industrial livestock-farming scale nationwide, delivering high economic efficiency, epidemic safety, and contributing to the development and direction of biosecure livestock farming trends in Vietnam's livestock industry.
