A study has been made of the effect of the boiled extract of Venerupis philippinarum upon 6-month growth of chicks fed ad libitum and upon egg production during the molting season. In growth assay were used female Single comb white Leghorn chicks hatched from eggs obtained from hens fed a normal diet. As shown in Fig. 1 the boiled extract given at 2-3% dry basis levels for 6 months showed a marked effect on the growth. The hens which had been fed practical ration containing fish meal were used for the egg production test. It has clearly been shown that the addition of the boiled extract at a 3.4% dry basis level prevented a reduction in the egg production during the molting season and was able to cut the consumption of fish meal at least 10 per cent (Fig. 2 & Tabble 3).
