Rate of absorption of hexoestrol from the ear of sheep

Abstract

Pellets containing varying ratios of hexoestrol to lactose were implanted into ears of sheep, and the proportion of hexoestrol absorbed during periods of 7 to 56 days, was determined. The results of two factorial experiments showed that absorption was more rapid when pellets were placed in the base of the ear and that absorption from individual pellets was not influenced by implanting in pairs. In addition, hexoestrol in pellets containing high proportions of lactose to hexoestrol was more rapidly absorbed than in those containing small proportions of lactose.
