№ 1 - 2014 ЗАКЛЮЧЕНИЕ Таким образом, венозное русло у коз зааненской породы в постнатальном онтогенезе состоит из парной поверхностной каудальной надчревной вены, от которой ответвляются каудальная вена и вена основания молочной железы. <...> Они собирают венозную кровь от краниальной и каудальной частей молочной железы коз. <...> Затем, отток венозной крови от молочной железы коз зааненской породы осуществляется по наружной срамной вене, сопровождающей одноименную артерию. <...> SUMARRY Vazorentgenoanatomichesky researches of a mammary gland of goats of zaanensky breed during the different periods of post-natal ontogenesis are conducted. <...> The main sources of outflow of blood from a mammary gland on three age groups are established. <...> As material for research the mammary gland from 30 females of goats of zaanensky breed aged from two weeks till two years delivered to chair of anatomy of animals from kozovodchesky economy of JSC Prinevskoye served. <...> By results of research it was for the first time revealed that the main venous highway in a mammary gland of goats of zaanensky breed is the pair superficial truncus pudendoepigastricus from which the caudalis vein and a vein of basis of a mammary gland branch off. <...> They collect a blue blood from cranialis and caudalis parts of a mammary gland of goats. <...> Then, outflow of a blue blood from a mammary gland of goats of zaanensky breed is carried out on the pudenda externi vein accompanying the artery of the same name. <...> Further, blood flows in a caudalis hollow vein and an external hypodermic vein. <...> All veins are, as a rule, doubled, settle down parallel to the arterial vessels of the same name <...>
