Sprouted barley mats promise concentrate substitution where pasture is absent, yet water accounting is rarely reported. We monitor daily sprout yield, metabolizable energy, and liter-per-kilogram output across three tray designs in commercial fattening barns. Modular vertical stacks improve water productivity without depressing average daily gain over six-week trials.

Pasture-based marketing claims proliferate, but premiums for verified forage feeding remain uncertain. We conduct discrete choice experiments in urban retail channels and estimate part-worth utilities for certification tiers. Results indicate meaningful premiums when traceability is third-party audited, though sensitivity rises during inflationary periods.

Parasitic weeds reduce clover persistence before field scouts notice chlorosis patches. We fly multispectral missions over experimental plots with graded infestation and train gradient-boosted models on texture and red-edge features. Early-season recall exceeds visual scouting, suggesting targeted roguing and seed-lot segregation.

Pelletizing straw and bran fractions could displace imported protein concentrates, yet emissions trade-offs are unclear. We model gate-to-farm impacts for two ration reformulations in coastal dairies, including transport of residues and electricity for pelleting. Scenario analysis shows net reductions when plants sit within 40 km of farms and grid intensity is moderate.

Riparian zones concentrate biomass but suffer compaction when herds linger. We equip herder groups with low-cost loggers and co-design hotspot maps with local committees. Overlaying tracks with biomass transects reveals predictable congregation nodes, enabling negotiated rotation calendars without excluding vulnerable stream buffers.

High-sugar warm-season legumes challenge standard homofermentative inoculants under prolonged wilting. We compare three commercial blends in laboratory mini-silos with delayed sealing to mimic field stress. Heterofermentative treatments improve aerobic stability after opening while limiting dry matter losses relative to untreated controls.

On-farm protein testing remains costly for small cooperatives blending legume and grass cuts. We build partial least squares models from 240 reference lots spanning three harvest windows and validate on independent bales. Cross-validated RMSE supports screening before baling without chromatography, reducing rejection at collection points.
