| Research Abstract |
To clarify the effects of light on growth hormone secretion in cattle, GH secretory patterns under various lighting conditions were determined. The present study showed that GH secretion has an ultradian rhythm with 6-h interval in this species and that photic stimulation can alter the secretory rhythm. It is possible that appropriate control of lighting conditions improves productivity of cattle via GH secretion in animal industry.
