Effect of Feeding Coconut Oil Meal on Milk Production and Composition1

Department of Dairy Science, The University of Arizona, Tucson

ABSTRACT

Twelve Holstein cows were used in a switchback feeding trial. Sixty per cent of the ration was supplied by good-quality alfalfa hay, the remaining 40% by one of four concentrates: (a) 15% cotton seed oil meal (control); (b) 3.75% added coconut oil; (c) 31% added coconut oil meal; (d) 3.75% added coconut oil plus 31% coconut oil meal. The rations were fed individually to each cow so that the total feed consumption equalled 110% of Morrison feeding standards for maintenance and production.

Observations were made on production and gross composition of milk, component fatty acids of the milk fat, digestibility of ration, and rumen volatile fatty acid (VFA) production. The following conclusions were made: (a) Rations with coconut oil or coconut oil meal are equivalent to those with cotton seed oil meal for milk production, (b) Rations of this type do not alter gross milk composition, (c) Feeding coconut oil or coconut oil meal increased the amounts of C12 fatty acid in the milk, (d) Digestibilities of the feed and combustible energies were greater in the rations with coconut oil meal or the meal with the oil added, (e) Concentrate mixtures with coconut oil or its meal depressed the total butyrate and valerate content of the rumen fluid.
