Abstract

Extract

Most investigators agree that, to be fully effective against cobalt deficiency disease, soluble cobalt compounds should be administered frequently. According to Lee (Citation1950) “Complete control of acute deficiency may be achieved by drenching once each week with 7 mg of cobalt … but 35 mg administered once in five weeks merely delays the onset of symptoms …”. Osborne et al. (Citation1954) and O'Moore (Citation1957) gave experimental doses of 14 mg fortnightly to lambs exposed to cobalt deficiency conditions and demonstrated significantly increased growth rates of treated animals as compared with untreated controls. However, it is doubtful whether those workers obtained complete remission of the disease with the treatment given, since Stewart et al. (Citation1955) made a direct comparison of the efficiency of 7 mg doses given weekly with that of 14 mg doses given fortnightly, and found that, on the latter regimen, lambs grew at a much slower rate than did those on the former.
