Fat granule size is key to reduced rumen breakdown

摘要

Protected fat specialist Volac Wilmar is warning dairy producers who feed high energy fatty acid supplements to satisfy the early lactation demands ofhigh yielding cows that the degree of protection is critical in ensuring the product is not broken down in the rumen with adverse consequences.According to the company, typical basal diets have 3-3.5% fat in the dry matter, but high yielders need 6-8% fat in the DM to meet requirements, or600-800g fat supplement a day.
