摘要：

Crossbred chicks 8 day old were used to investigate the availability of vitamin B-6 from yellow corn, solvent-extracted soybean meals (SBM) and autoclaved, full-fat soybeans (Harosoy variety). The corn was either nonroasted or roasted to temperatures of 80.degree., 120.degree. and 160.degree. C. Using a standard curve procedure with growth as the criterion, the concentration (ppm) of available vitamin B-6 was estimated to be 2.68, 3.15, 2.99, 2.22, 4.67, 4.95 and 3.32 for nonroasted corn, 80.degree. C corn, 120.degree. C corn, 160.degree. C corn, SBM, dehulled SBM and autoclaved Harosoy, respectively. The chick''s requirement for available vitamin B-6 was estimated to be 1.1 ppm. Chick growth was observed to be a better indicator of available vitamin B-6 activity than blood glutamic-oxalacetic transaminase activity.
