Morphology of mammary gland in doggesses during lactation period

Cover Page

Abstract


Mammary gland morphology studies were carried out on 12 lactating doggesses at the age of 2-8 years old at the Departament of Animal Anatomy and Physiology of Kostroma Agricultural Academy in 2006-2008. The mammary hillocks forming the multiple gland have been found to vary in macro- and microscopic parameters during lactation. The morphometric charasteristics of groin and abdominal mammary hillocks are 1,5 times as high as those of cranial ones.The parenchima-stroma ratio is an interior characteristic of mammary gland determining its functioning.The proportion of connective tissue to glandular tissue is 1 to 2 in the groin hillocks, 1 to 1,5 in the abdominal, and 1 to 0,7 in the cranial ones. Alveola are lined mostly with cubic, and also cylindrical and flat epitelium.
