The Effects of Various Photoperiods on Development of Adrenal Gland in Chicks
Abstract
This study was carried out to investigate the effects of various photoperiods on development of adrenal gland in chicks. The study population was consisted of 144 broiler (ROS 308) chicks. As soon as they hatched, the sex of chicks were determined. The chicks were divided into two groups as male and female. Then the chicks were assigned into two photoperiod groups as 16 hours (16L-8D) and 24 hours (24L-0D). In this study, a total of 288 adrenal glands morphologic characteristics such as the diameters and weights were measured. In the morphologic analysis, right and left adrenal gland weight of the first and eighth days old chicks were statistically different from related aged chicks in 24 h photoperiod group (P<0.05). In addition, left adrenal gland width of 14 and 42 days old animals in 16 hours photoperiod group (16L-8D) and in 24 hours photoperiod group (24L-0D) were significantly increased compared with control group (P<0.01). Right adrenal gland weight of males groups were heavier than females groups (P<0.01).
