Dr Stephan Tait: AWMC research and development in Agri-industry

This talk will outline some of the key research activities of the AWMC in Agri-industries and will summarise some key outcomes from a number of projects across the interface of anaerobic technology and nutrient and resource recovery. The intent is to describe the context for current work and to provide a framework for future engagement with agri-industries so that we can effectively harness research and development opportunities for the benefit of participating industries and for a steady supply of funding for future research and development. For the technically-oriented the talk will outline some interesting outcomes of on-farm testing of biological biogas scrubbing technology with comparably minimal capital and operating costs, and of a novel manure solid separation technology called the Z-filter which boasts a very small footprint and excellent solids removal performance with a stackable manure solids cake and filtrate with predominantly dissolved solids. This latter technology was trialled in-line at a commercial piggery to investigate a pond-less manure treatment system with direct reuse of low-quality filtered water for shed cleaning, to minimise water use and overall system cost.

 

Dr Kenn Lu: Diet type formulates hindgut microbiome and leads to variation of nutrition outcomes in pigs

Microbial ecology of hindgut is directly related to host nutrition, welfare and health and can be affected by many environmental factors such as diet. In this study, the influence of diet on microbial ecology of pig hindgut and further affecting the nutrition outcomes were elucidated in well-controlled replicated trials. Microbial community in hindgut was monitored by Illumina Miseq 16S rRNA gene pyrosequencing on faecal samples collected fortnightly over 12 weeks. Microbial communities were driven by diet type towards specific groups of bacteria including lactic acid bacteria. Nutrition outcomes were most benefited from even distribution of LABs formulated by sorghum based diet.
