    Gross, histological and biometrical studies on oviduct of guinea fowl (Numida meleagris)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-07) Kanchana, R.; Singh, Balwinder
    The present study was conducted on five birds of non-laying guinea fowl of 6 months of age and two laying guinea fowl of 10 months of age envisaged for gross morphological, histological and biometrical studies. The left oviduct of all five non- laying birds was small, less developed, gross demarcation of oviduct into various regions as infundibulum, magnum, isthmus, shell gland and vagina was not possible. The left oviduct of all laying birds was fully developed and differentiated into infundibulum, magnum, isthmus, shell gland and vagina. The mucosal folds in all segments of oviduct of non-laying birds were short and small, lined by pseudo stratified columnar ciliated epithelium. Lamina propria of last segment of non-laying birds showed tubular glands, all other segments were devoid of glands. Lamina propria sub mucosa was composed of collagen, reticular and elastic fibers. Distinction between inner circular and outer longitudinal muscle layers in tunica muscularis were lacking in all segments of non-laying birds. Mucosal folds were primary, secondary and tertiary in the infundibulum, primary and secondary branching in the isthmus, shell gland and vagina. Infundibulum,magnum, shell gland and vagina were lined by pseudo stratified columnar ciliated epithelium. Isthmus was lined by pseudo stratified columnar epithelium. Tunica muscularis was most developed in vagina and least developed in infundibulum. Distinction between inner circular and outer longitudinal muscle layers in tunica muscularis were lacking in infundibulum and magnum, but this distinction were observed clearly in isthmus, shell gland and vaginal regions.
