Abstract
Aquatic weeds from Cayuga Lake in New York were included as 10% or 20% dry weight of rations which were fed to growing pigs for 69 days. The animals gained weight at a rate comparable to those on a basal diet or a diet in which an equivalent weight of alfalfa replaced the aquatic plants. The feed efficiency (kg ration consumed/kg wt gained) of the aquatic rations was significantly lower, probably because of the lower nutritive value of the aquatic plants. Polychlorinated biphenyls (PCBs) were found in the aquatic plants (0.59 ppm, dry weight) and in the pig fat of those fed the aquatic ration. Hepatic microsomal mixed function oxidase activity was not significantly different in the animals fed the various treatment rations. Histopathologic examination of animal tissues revealed no lesions or abnormalities which could be attributed to the diets.
