Forty rats were used to examine the effect of plane of nutrition on the growth response of rate to castration. Rats were offered 8, 12, 16 or 20 g/rat/day of a commercial small animal feed.

The results indicated that the effect of castration on growth of rats may be attributable almost entirely to an effect on appetite.
