Abstract

This article synthesizes evidence on how screw-extrusion followed by pelleting can tailor compound feeds to improve nutrient use in ruminants. Extrusion can produce pellets with targeted density and fluid stability by altering starch gelatinization, protein functionality, and fiber structure, potentially shifting rumen degradation kinetics and nutrient flow to the intestine. This article identifies extruder settings needed to achieve the desired pellet density and fluid stability for rumen control, and defines and evaluates ruminant-specific physical properties of extruded feed pellets.

Abstract

Presentation of preliminary findings from a feed trial conducted winter 2024, where the effect of feeding lactating dairy cows a 100% ensiled grass pulp diet was measured on production parameters, GHG-emissions, behaviour and metabolic markers, compared to regular whole plant silage from the same ley and harvest dates
