Abstract

Chlorhydroxyquinoline (CHQ) was fed at levels from 31 to 125 gm./ton of ration to individually fed fattening lambs with variable results. In Trial 1 lambs fed CHQ at a level of 31 gm./ton gained 0.29 lb./day and required 7.50 lb. feed per pound of gain, while controls gained 0.22 lb./day with 8.95 lb. feed needed per pound of gain. A significant increase in rate of gain was also noted with the 62-gm. level. In a second similar experiment no significant differences in rate of gain were observed. Lambs fed 62 gm. CHQ/ton of feed were more efficient in their feed conversion (6.78 vs. 7.97 lb. feed/lb. gain) than the controls. In a third experiment using levels of 0, 31, 62, and 125 gm. CHQ/ton of feed, no significant differences were observed in any of the observations recorded. The possible role of the previous environment is discussed.

A digestion trial comparing rations containing 0 and 62 gm. CHQ/ton revealed no significant differences in digestibility of any of the nutrients studied.
