ABSTRACT
After 10 days depletion period with niacin free diet, weanling rats were repleted with either reference diets containing niacin at four levels (2, 4, 8 and 12 mg/kg diet) or test diets containing test material at two levels as source of niacin. Gains in body weight and hepatic pyridine nucleotides content increased with increase in niacin intake. The correlation coefficient for hepatic pyridine nucleotides content and niacin intake was 0.98, whereas for weight gain and niacin intake was 0.89. Dried skim milk and pearl millet were taken as test materials. Dried skim milk with most of its niacin in free form showed 98% niacin equivalent to be bioavailable whereas in pearl millet niacin was in bound form and bioavailability equivalent was only 48 per cent.
