Effect of Arsanilic Acid on Growing Chicks

Abstract

Fifty-one White Leghorn X Rhode Island Red hybrid chicks of our experiment station from 3 days to 9 weeks of age, were fed a ration containing arsanilic acid at a rate of 100mg per kg of the basal diet. The compostion of the ration is shown in figure 1.(Arsanilic acid used was a product of the Toshiba-Seiyaku Co., Ltd.)
At 3 weeks of age, the mean body weight of the chicks fed the ration containing arsanilic acid was 20g heavier than that of chicks fed the same ration without addition of arsanilic acid (P<0.01). The increase of body weight was 727g in the former after 9 weeks, treatment, while it was in 619g the latter at the same period (P<.01).
It was clearly shown in the present experiment that arsanilic acid had a growth-promoting effect on chicks when used as feed additive.
