The Relative Values of Green Oat-Sprouts, Green Alfalfa, and Cod Liver Oil, in the Prevention of Rickets in Growing Chicks

The experiments on which the data contained in this paper are based were suggested by the fact that various kinds of green feeds, which have been found to prevent rickets in mammals, did not, in similar quantities, prevent rickets in growing chicks. 1 On the other hand, both ultra-violet light and cod liver oil have proved effective in preventing rickets in growing chicks and mammals. In view of these facts it was determined to conduct an experiment to determine the relative values of green oat-sprouts, green alfalfa and cod liver oil in preventing rickets in growing chicks, both in the presence and absence of ultra-violet light and direct sunlight. EXPERIMENTAL For this purpose, nine lots of day-old chicks, 25 chicks in each lot, were used. These lots were divided into three groups of three lots each, and each chick was banded. Each lot was confined in a separate pen. The nine . . .
