Tom O’ Callaghan - explains the excellent benefits of a pasture-based diet in cows to a society that is increasingly interested in incorporating more natural ingredients into their daily diet. Tom O’ Callaghan set out to look at the effect of cow diet on raw milk composition and quality through the ‘Profiling Milk from Grass Project’ - a Teagasc funded project with support from the APC Microbiome Institute in Cork. The goal was to assess the effects of different feeding systems on the composition, quality, sensory and characteristics of milk and dairy products.
