In a trial of 3 x 3 Latin square design 3 dairy heifers were given 1 litre of a 5.4% solution of glucose, a 25% solution of glucose or a 0 9% solution of NaCl as control. The feed was a completely pelleted diet of lucerne meal and ground maize 6: 4 given to appetite. The increased availability of glucose did not reduce intake of feed. Intraruminal infusions of acetate, propionate, butyrate or a mixture of volatile fatty acids each supplying the same energy was given to 2 cows with fistulae, fed to appetite on a pelleted diet, and to 2 cows given long lucerne hay. On both diets voluntary intake of feed was reduced by any of the infusions.
