Witold Brudnicki, Benedykt Skoczylas, Ryszard Jabłoński
The research investigated 56 adult individuals of racoon dog, including 27 males and 29 females. The research of the selected features of same parts of the alimentary canal and liver in racoon dog allowed to define absolute length and capacity of intestine as a whole as well as of its respective sections, as well as the capacity of stomach and the liver weight. The parameters of relative length of intestine at its respective sections calculated against the body length as well as the relative capacity of the intestine and stomach calculated against the body weight of animals show similar values and there were observed no significant differences between them, which means that the proportions of the length and capacity in both sexes are similar, while the differences in absolute parameters result from animal body size differences. The present research shows the racoon dog intestine’s metrical features point to some adaptation to the intake of considerable amounts of plant feed.
Key words: metrical features, alimentary canal, liver, dog.
