Feeding Calcium Salts of Fatty Acids to Lactating Cows

Abstract

Digestibility and production responses to feeding Ca salts of fatty acids were determined in lactating cows. Cows 120 d in milk were fed 4% of DM as Ca salts of fatty acids using chromium oxide mordanted corn silage as unabsorbed reference substance. Digestion of DM and N did not change, fatty acid digestion increased, and Ca percentage absorption decreased. Milk and milk fat production were enhanced.
