The present study was conducted to compare the plasma levels of melatonin, ghrelin, steroid hormones, amino acids, expression of hormone receptors (MNTR, GHLR), and amino acid transporters (AAts, 4 nos.) during early (EP, 24-28 weeks) and mid (MP, 32-36 weeks) laying period. Hormones melatonin and ghrelin have been associated with ovarian function in chickens. Till date no reports are available with respect to mentioned physiological parameters on the production performance and their modulation by Se (selenium) treatment in Vanaraja Chickens. Vanaraja chickens at 22 weeks of age were divided equally into two groups. Control group was reared on a basal diet containing 0.3mg of inorganic Se. Treatment group was offered additional 0.3mg of organic Se enriched yeast during EP and MP. When compared between the control groups of EP and MP, the mean level of all the hormones was higher at EP. The expression of all the AAts and MNTR was higher in jejunum, compared to magnum, except for CAT and GHLR during EP. When compared to control group supplementation of selenium increased the level of plasma hormones and amino acids significantly (P < 0.05) during MP. When compared between EP and MP, treatment with Se increased expression of 2-3 number of aats and decreased MNTR in both the tissues significantly at EP, whereas expression of only GHLR increased in magnum. The Se treatment did not cause significant change in the expression of receptors, at MP. In conclusion, additional Se supplementation increased the utilization of hormones and modulation of the physiological parameters was higher in magnum tissue resulting in a beneficial effect on increased egg production (2%), and body weight (P < 0.01) during EP and MP.
