Large granules is an effective way to optimize cow performance: Research

Granule size has a major impact on the degree of rumen-protection of fat supplements according to research by Volac Wilmar Feed Ingredients at the National University of Singapore. The physical nature of calcium salt supplements is a key factor in the success of delivery of fatty acids through the rumen in their active form to dairy cows.

Dr Richard Kirkland, Global Technical Manager for Volac Wilmar Feed Ingredients has said that rumen-protected fats are manufactured to avoid reductions in fibre digestibility and avoid bio-hydrogenation of unsaturated fatty acids. He explained that selecting the Megalac calcium salt brand, which has been manufactured to have a higher proportion of large granules, is an effective way to optimize cow performance by improving fatty acid supply.

According to Professor John Newbold, PhD, Professor of Dairy Nutrition at Scotland’s Rural College, individual fatty acids have their effects on milk yield, milk fat content, body condition score and fertility at different periods of lactation. Dr Kirkland said Rumen-protected fat supplementation not only helps meet energy requirements, but also supports specific areas of performance.

To maximize returns from specific milk contracts, fatty acids should be selected depending on the stage of lactation, individual farm challenges and contract requirements.
