Из ярок18-мес. возраста сформировано три группы по 15 голов в каждой. В случную кампанию эти ярки случены с подопытными козликами. Результаты исследования показали, что проверка племенных качеств козликов с оценкой их потомства в 4-мес. возрасте позволяет раньше выявить улучшателей и тем самым уменьшить затраты на содержание козлов, являющихся нейтральными или ухудшателями, а главное повысить качество потомства, получаемого от козлов-улучшателей.</p></abstract><trans-abstract xml:lang="en"><p>3 goats aged 7 months were selected.

The results of the study showed that the test of breeding qualities of goats with an assessment of their off spring in 4 months.
