Беременность нутрий


Беременность нутрий

Для оплодотворения самки достаточно 3—4 покрытий. Овуляция у нутрий провоцированная и происходит только после спаривания. Как уже указывалось, нутрии могут давать приплод в любое время года. Состояние половой охоты у самок нутрий повторяется через 25—30 дней, причем возможны небольшие отклонения в ту или иную сторону.

В первую половину беременности в яичниках самок можно наблюдать хорошо развитые желтые тела. Но уже со второй половины начинается их обратное развитие, и в ряде случаев у только что родивших самок их уже нельзя обнаружить. В связи с этим у нутрий часто в конце беременности уже есть некоторое количество созревших фолликулов, в результате чего на 1—3й день после щенения самка может прийти в охоту и быть оплодотворенной. Но развитие фолликулов в период беременности наблюдается не у всех самок, сразу после щенения, по данным ряда хозяйств, оплодотворяется только 10—20 % самок, а большинство имеет полноценную охоту только через 2550 дней.

Беременность продолжается 126—137 дней, и ко времени щенения у самок, совмещающих беременность с лактацией, молодняк уже успевает перейти на самостоятельный образ жизни.
У самцов начальные стадии сперматогенеза можно наблюдать по достижении ими 33,5месячного возраста. Половая зрелость наступает в 4—6 месяцев (в зависимости от условий), но к покрытию самок их обычно допускают только в возрасте 8—10 месяцев.

При наблюдениях за нутриями на воле в период их акклиматизации в зимние месяцы, когда условия резко ухудшались, нередко встречались самцы с семенниками в стадии дегенерации, не способные оплодотворять самок. В клеточных же условиях при нормальном кормлении самцы активны весь год.

Тем не менее их надо периодически проверять, особенно при содержании с группой самок: иногда самцы оказываются не способными покрывать их или из-за выпадения пениса, что чаще всего бывает в результате травматических повреждений, или из-за образования на нем кольца из налипших волос. Одного самца можно держать с группой в 10—15 самок.
