Abstract

Додатну і статистично вірогідну кореляцію встановлено між селекційним індексом за типом екстер’єру батьків і їх потомків (r = +0,364 ± 0,0503 – +0,611 ± 0,0396), а також між оцінкою за типом екстер’єру в балах батьків і їх дочок (r = +0,210 ± 0,049 – +0,586 ± 0,033). Додатна і статистично вірогідна кореляція встановлена між оцінкою вимені дочок батьків бугаїв і дочок бугаїв (r = +0,408 ± 0,049) і матерів бугаїв та дочок бугаїв (r = +0,381 ± 0,049).

Низький від’ємний коефіцієнт кореляції встановлено між розміром тіла дочок бугаїв і їхньою молочною продуктивністю за 305 днів першої лактації: -0,095 ± 0,0513; молочний жир – +0,003 ± 0,0518; білок – +0,055 ± 0,0516.
