Localization of Phosphatases, Oxidoreductases and Esterases in Different Segments of Oviduct in Laying Punjab White Quail

The present study was conducted to observe the distribution pattern of phosphatases, oxidoreductases and esterases in different segments of oviduct in Punjab white quail. The study depicted that the activity of alkaline phosphatase was moderate to strong in propria submucosa of all the segments of the oviduct, while negligible to weak in other layers.The SDH, LDH and G-6-PD activity was weak to moderate in lamina epithelialis in all segments except magnum where it was negligible to weak. NADH had stronger reaction in lamina epithelialis of infundibulum,whereas NADPH showed weak to moderate activity in lamina epithelialis and moderate in propria submucosa of infundibulum and magnum.The reaction of non specific esterase in lamina epithelialis was weak to moderate in the infundibulum, magnum, uterus and vagina whereas moderate to strong activity in isthmus while propria submucosa showed moderate activity in infundibulum, uterus and vagina and weak in magnum and isthmus. The infundibular, magnal and sperm host glands showed weak to moderate activity of different enzymes studied. The variation in enzymatic activity may be correlated with the reproductive status of the Punjab white quail. * Corresponding author KEYWORDS
