Отбор


Основными приемами селекционной работы являются отбор и подбор. Цель отбора — выделить зверей, отличающихся наилучшей аследственностью и устойчиво передающих в данных условиях положительные, хозяйственно полезные признаки потомству. Создание разнообразных пород животных, выведение зверей с большей или меньшей длиной волосяного покрова, увеличение интенсивности серебристости у лисиц, изменение оттенков окраски — все это результат тщательного отбора племенных зверей с незначительными, но нужными отклонениями от средних показателей.

При проведении отбора в стадо следует включать таких зверей, которые не только сами отличаются высокими показателями хозяйственно важных признаков, но и устойчиво передают их потомству. Особое внимание следует обратить на зверей со значительными наследственно обусловленными изменениями — мутациями.

При отборе необходимо всесторонне, достаточно точно оценить каждое животное по комплексу признаков, причем особое внимание обращают на те показатели, улучшение которых в данном хозяйстве является первоочередной задачей. На племя оставляют лучших по этим показателям зверей, даже получивших несколько более низкую оценку по другим, менее важным, признакам. Иногда в хозяйстве комплектуют несколько групп, в каждую из которых входят сходные звери, лучшие по одномудвум признакам, но недостаточно хорошие по другим. Например, в одну группу выделяют зверей наиболее крупных и с самой темной окраской, но со средними показателями опушения, а в другую крупных, с отличным опушением, но худших по окраске. При подборе пар в каждой группе закрепляют имеющиеся положительные качества и одновременно ведут работу по улучшению недостаточно хороших.
