THE EFFECT OF HEAT AND MOISTURE ON THE FEEDING VALUE OF PILCHARD MEAL By WILLlA\1 B. LA\JHAM. Jr. and HUGO W '1L50N, Research Report 3, U"'I rLD STATES C.OVCRNML" r PR INTING OI"FICE WA.':>HINGTO;>l : 1~42
The fish meals produced today have in general proved to be excellent sources of protein for the balancing of farm-animal rations. Some potential users, however, have refrained from feeding these products because of reports implying that fish meals, when fed to farm animals and poultry, have cause symptoms of toxicity.
It was considered possible that the meals suspected of producing toxic symptoms may have been subjected to conditions after manufacture that had altered them in an unsatisfactory manner. Therefore, the effect of excessive heat and humidity to simulate extremely unsatisfactory storage conditions was studied with pilchard meal.
Pilchard meal was incorporated into otherwise purified diets containing as much as 25 percent of protein; of which more than 95 percent had been derived from pilchard meal. When these diets were fed to rats and chicks it was found that the excess heat and high humidity had not adversely altered the nutritive value of the meal. This indicates that fish meals can be used liberally in farm-animal rations as a source of minerals and superior protein, provided ordinary care is used to balance properly the ration for the other essential food elements.
