Plokhinsky. reliability heritability correlation determined Student's t-test. Then studying it established that births average 10.61 heads, milkness — 51.34 kg, months 156.72 kg. Hereat coefficient variability on 12.95%, 8.41%, 10.02%. 15.00%, 20.00%, 25.00% (P > 0.999). between months, respectively, r = +0.769 + 0.474, 0.754 under probability infallible prognoses P 0.999.
