The effect of the number of animals per cage on the growth of the rat

1973

Hughes, P. C. R. | Nowak, M.

Animals were bred and reared normally, but at weaning were distributed either singly, in pairs, or 4 to a cage. Measurements of length and weight were made during the growth period. In females there were no differences between the caging regimes, but males kept 4 to a cage were significantly smaller than those kept 2 to a cage or singly.
