Abstract
Objectives were to determine the effects of adding 3 g/d of Aspergillus oryzae fermentation extract to diets with or without 5.6% added tallow. Twenty-eight Holstein cows ( = 98 d of lactation) were assigned to a randomized block experiment in a 2 × 2 factorial arrangement of treatments. Treatments were the basal diet 1) without tallow or extract, 2) with extract but no tallow, 3) with tallow but no extract, and 4) with tallow and extract. Milk production, dry matter intake, 3.5% fat corrected milk, digestibility of neutral detergent fiber in the total tract were depressed for cows fed tallow. Addition of fermentation extract did not stimulate fiber digestion or milk production of cows fed diets with or without fat. Addition of extract did not overcome depression of fiber digestibility by cows fed tallow.Keywords
