Degtyar'ov M. Influence of paratypical factors on morphofunctional state of mammary gland and on quality of milk in cows

Object for investigation - cattle. The aim of the investigation - to study morphological state of udder and milk qualities in cows depending on paratypical factors. Methods used: zoohygienic, hematological, mechanical, morphofunctional, histometric. Theoretical and practical results: problems of influence of floors and walls of different constructions, up-to - date sanitary and hygienic methods that increase morphofunctional status of mammary gland, quality of milk in cows, health of heifers and further productivity and resistance to mastitis in first - calf heifers have been studied. Economic efficiency: introduction of floor and wall constructions with the improved thermotechnical characteristics is on the average 96,90 grivans per a years. Introductions of message of udder gives the profit - 336,54 grivans per an animal.
