The effect of light intensity on turkey poult eye morphology

In each of two studies the influence of light intensity on the eye morphology of poults was examined. The light intensity treatments were started on the day of hatching and consisted of 1.1, 11, 110, or 220 lx from incandescent bulbs for 23 hr each day. Eye weight, anterior-posterior diameter, and transverse diameter were significantly increased only in the 1.1 lx treatment of both tests. Under the conditions of this test it was concluded that eye morphology of poults can be changed by low light intensity of 1.1 lx but not 11, 110, or 220 lx.
