Arup Kalita, Pranab Chandra Kalita and Probal Jyoti Doley

ABSTRACT

The morphology and morphometry of the urinary system was conducted on each of six adult Mizo local pigs of either sex. The adult body weight of the animals was recorded between 27.0 to 38.0 Kg. The kidneys of Mizo local pigs were brown coloured, smooth surfaced and bean-shaped. They were flattened dorsoventrally, elongated with slightly pointed poles. The left kidney was located little cranial than the right one. The cranial extremity of the right kidney had no contact with the liver. The renal pelvis was funnel shaped and divided into cranial and caudal major calyces. The major calyces give off eight to twelve numbers of minor calyces. Each of the minor calyx contained a renal papilla. The renal pyramids were distinct and renal columns were present between the pyramids. The length of the ureter was slightly longer in the left side than the right in both male and female animals. The urinary bladder of Zovawk was large and oval shaped in empty condition. The caudal part of the female urethra was fused with the vagina and produced a corresponding elevation of the floor of the vagina. The male urethra was divided into pelvic and penile parts.
