The comparative estimation of growth and development young cows is given, to dairy efficiency and morphofunctional properties of an udder first-calf cows, received from manufacturers Holstein and Red-and-white cattle Swedish breeds for perfection of red-and-white cattle. It is established that intensity of growth at young cows does not decrease to 18-month's age, and first-calf cows in dairy efficiency and morphofunctional to properties surpass thoroughbred animals of redand-white breed.
Дана сравнительная оценка роста и развития телочек, молочной продуктивности и морфофун-циональных свойств вымени первотелок, полученных от производителей красно-пестрой голштинской и шведской пород для совершенствования красно-пестрого скота. Установлено, что интенсивность роста у телочек до 18-месячного возраста не снижается, а по молочной продуктивности и морфофункциональным свойствам первотелки превосходят чистопородных животных красно-пестрой породы.
