DR. H. C. GIVENS, State Veterinarian.

The following is a resume of the work accomplished during December 928 in cooperation with the United States Bureau of Animal Industry nd various counties in the State:

Parasites of hogs cause enormous annual losses to the hog industry in Virginia. The parasites responsible for these losses are principally round worms, thornhead worms, lung worms, and kidney worms. The first losses encountered are the result of these worms attacking pigs early in life and the death of many pigs. The second loss is the stunting of the pigs while very young which causes growth and gain to be slow and consequently expensive. The third loss that is encountered is at the time the hogs are sold when they are not nearly as large as they should be and when slaughtered valuable portions of their carcasses are unfit for fool and are condemed because they are infested with parasites.

Kidney worms which are found at the time of slaughter imbedded in the carcasses of the hogs in the region of the kidneys are the ones responsible for the greatest losses. These worms often cause hogs to be so badly discolored and emaciated that the entire carcass is unfit for food and more frequently infest the leaf lard and tenderloin to the extent that large portions of these valuable parts of the carcass must be trimmed as unfit for food. Kidney worms by interfering with the normal circulation of the blood often causes enlargement and hardening of the liver of hogs to the extent that the liver at the time of slaughter is unfit for food and must be condemned.

Buyers of hogs are aware of this loss which must be encountered at the time of slaughter when they buy the hogs and therefore pay the hog producers from one-fourth to one-half a cent per pound less than they would pay if the hogs were not known to be in this condition; therefore, the producers of hogs are the ones who suffer and should be the ones to remedy the situation.

Parasites in hogs may be successfully combatted by taking the sows before farrowing time to clean ground which has not been occupied by hogs for more than a year and allowing the pigs to be farrowed and kept on this clean ground until they are four months old. Under no condition must the pigs be allowed to visit the old premises and hog lots contaminated with worm eggs.
