Evaluation of Bacillus amyloliquefaciens H57 as a probiotic in livestock using animal nutrition studies and metagenomics (2013-2018)
Abstract
A major problem with animal feed quality is fungal growth during storage. Biological control will be used to reduce this by inoculating feed materials before formulation with Bacillus amyloliquefaciens strain H57 which antagonises growth of the fungi. H57 inoculated hay also produced a probiotic effect on nitrogen metabolism in sheep. Animal nutrition trials of beef and sheep weaners and poultry will assess the effects of formulated, H57 inoculated feeds on weight gain and feed utilisation efficiency particularly of nitrogen, protein and energy. Rapid pyro gene sequencing will assess changes in microbial community structure and function and survival of H57 in the rumen and poultry gastrointestinal tract.
