Первые опыты по клеточному разведению бобров


Любви Учим знакомиться и соблазнять
Первые опыты по клеточному разведению бобров были начаты в нашей стране в 30х годах в Воронежском заповеднике (Воронежская область). Работа сотрудников бобровой фермы позволила достаточно полно изучить биологию этого вида, что было необходимо для разработки методов его клеточного разведения.

Большинство самок бобров давало первый приплод в возрасте 3—4 лет. Только очень небольшой процент самок достигал половой зрелости в 2 года. Размножение бобров ограничено сезоном. Спаривания бывают с конца декабря до конца марта. Если самка не оплодотворилась при первом спаривании, охота у нее может повториться через 1415 дней. Спаривание чаще всего проходит ночью. В период гона для бобров необходимо наличие водоема, так как самец кроет самку, находящуюся в воде, подплывая под нее.

Беременность продолжается 105107 дней. Средний размер помета 23 щенка. У диких бобров обнаруживали по 79 эмбрионов. Продолжительность лактации 45—55 дней.

Щенки рождаются хорошо развитыми: они опушены, с прорезавшимися зубами, с открытыми глазами. Средняя масса 450650 г. Примерно до 10дневного возраста они плохо передвигаются в воде и совсем не могут нырять. Рост молодняка продолжается до 34 лет, и к этому времени большинство достигает половой зрелости. Продолжительность жизни 2025 лет. Известны случаи получения приплода от 1819летних самок, но при содержании в клетках большинство живет не более 78 лет.

В связи с относительно поздним половым созреванием и малой плодовитостью воспроизводство стада идет медленно. Содержание бобров затрудняется тем, что для них зимой во время гона необходимо наличие в клетке свободной ото льда воды. Использование естественных водоемов, как это было сделано в первые годы работы в Воронежском заповеднике, для промышленных ферм практически невозможно, так как требуется слишком большая протяженность береговой линии и значительные затруднения вызывает ежедневная очистка ото льда прорубей. Следовательно, для бобров требуются закрытые отапливаемые (для поддержания плюсовой температуры) помещения с проточной водой: бобры калятся в воду и необходима ее регулярная смена.

Питаются бобры исключительно растительной пищей. Им дают небольшое количество концентратов (овес, отруби), зимой корнеплоды, летом траву и весь год древесную растительность.

Разведение бобров не может сейчас дать положительного эффекта, так как нет спроса на продукцию боброводства.
