9 AM - Administrative report – Adel Shirmohammadi

9:40 AM – Dave Combs – WI report – Assessing fiber digestion total tract ndf digestibility (ttndfdig) model, a way to predict fiber digestibility, in vitro evaluation to predict total tract digestibility

Have focused on standardized rumen fluid, rumen bugs are primed by taking the collected rumen fluid to and adding nutrients to get the bugs into the log growth phase and then using the stimulated bugs for in vitro work, this has reduced run-run variation

Evaluating low lignin alfalfa, and alkali treatment of corn stover and corn silage

Effect of dextrose and starch on enteric methane emission

10 AM – Joe’s report

10:30 AM – Al’s report – new version of IFSM released, no major changes, just cleaning up of coding.

Have added update on VOC from silage and bedded pack option

There is now a carbon cycling focus

Dairy Agroecosystems work group – (DAWG) – TX, PA, MN, WI, ID – quantify reactive N losses in dairy systems

Sustainable Dairy (CAP) – WI – NIFS funded multi-state grant – GHG emission and mitigation BMPs

Sustainable beef – major focus, most of carbon footprint is associated with the grazing part of the management system

Would Al consider hosting the meeting in 2017, yes.
