THE COMPARISON OF FUNDIC GLANDS, INTESTINAL GLANDS AND VILⅡ OF JEJUNUM,AND COLONIC GLANDS BETWEEN NORTHEASTERN NATIVE AND HARBIN WHITE PIGS

But at unit length, the number of fundic glands in newborn and 15kg body weight native, piglets were significantly more than that of Harbin white. All other diffirenes were not significant. In the Jejunum, the number of intestinal glands and villi at unit length of Northeastern native breed was not significantly different from that of Harbin white.

So far as the changes of height ofvilii of both breeds were concerned, the newborn piglets were all significantly greater than ones of 15kg, 30kg stages. And the height of 30kg was zreater than that of 15kg. The number and height of the colonic glande at 30kg. Stage were significantly different between the tow breeds.
