Ленинградский тип высшее достижение в селекции молочного скота России

Abstract

На основе использования лучшего отечественного и мирового генофонда (голштинской породы) создан новый высокопродуктивный, конкурентоспособный тип черно-пестрого скота, не уступающий европейским аналогам, с генетическим потенциалом более 10 000 кг молока за лактацию. Наибольший генетический прогресс обеспечило поглотительное скрещивание черно-пестрых коров с голштинскими быками-производителями. В результате селекционной работы удой за последние 10 лет повысился на 3700 кг, содержание белка в молоке на 0,06 %. Возраст первого осеменения снизился на 3 месяца, живая масса при первом осеменении составила 417 кг (+44 кг), возраст первого отела 24…26 мес.

On the basis of crossing of the best native and world genofond (holstein breed) the new, highly productive, competitive type of the black and white cattle which is not conceding to the European analogues, with genetic potential more than 10000 kg of milk for lactation was created and introduced to manufacture
