Effect of the Ingestion of Porrocaecum (Codworm) on Growth, Voluntary Intake and Feed Efficiency of Beagle Pups

In a series of four feeding trials involving 94 beagle pups, it was shown that supplementation of a control ration with codworms at levels up to 80 per day (equivalent to 80 per 1000 Calories of intake), did not significantly impair the efficiency of feed utilization or induce any deterioration in the general health of the pups. Digestibility of this control ration, which consisted of dog meal plus a meat source, was not significantly altered by the addition of 20 codworms to the daily intake of each pup.
