It was found that in different age periods of heifers of the Ukrainian black-spotted dairy breed by growth intensity significantly (P < 0,01) analogues of the Ukrainian red dairy breed prevailed, and the coefficient of variation with age on this basis decreased for both breeds
The coefficients of recurrence of live weight of the studied heifers, which are quite significant at high probabilities, were revealed, which indicates the possibility of effective early selection
Summary
THE GROWTH AND REPRODUCTIVE ABILITY OF HEIFERS AND FIRST-CALF COWS UKRAINIAN RED AND BLACK-SPOTTED DAIRY BREEDS IN THE CONDITIONS OF THE CENTRAL REGION OF UKRAINE G. Метою наших досліджень було вивчення динаміки живої маси і відтворної здатності телиць і корів-первісток українських червоної та чорно-рябої молочних порід та рівня їх зв’язку. Вивчались показники росту: жива маса у 3-, 6-, 9- ,12- та 15-місячному віці, при І-му осіменінні.
