Production and application technology of probiotics to improve growth performance of farm animals and decrease ammonia concentration of manure
2022.06.30
In response to the important issues of climate change and net zero emissions, reducing carbon emissions from livestock farming is one of the important goals of agricultural production. Adding probiotics to the feed to improve feed efficiency is indeed a feasible measure for carbon reduction. This technology is to screen and identify potential probiotic isolates from the livestock production environment. After molecular analysis, the isolates are confirmed to be positive listed microorganisms in feed additives, and the analyses on their important characteristics are completed including the comparison of important decomposing enzyme activities (protease, lipase, α-amylase, β-glucanase and xylanase), animal validation tests and sporulation production condition tests. Therefore, this R&D technology can provide high-quality probiotic products for industrial selection and application.
The isolate screened by this technique has been identified and named Bacillus subtilis TLRI 211-1. In the analysis of the activity of important decomposing enzymes, it was shown by the comparison of the size of the transparent area of the enzyme decomposition substrate around the colony of the culture plate that the TLRI 211-1 strain had better activity performance than the commercial product A strain.
