牛蛙是变温动物,当水温下降到6～12℃时开始冬眠。此期管理应注意以下三点: 一、越冬前要保膘牛蛙进入冬眠后,潜伏在水底或洞穴中不进食,依靠皮肤呼吸水中的溶氧和体内蓄积的养料来维持低微的新陈代谢。所以,在冬眠前应抓紧促膘,每天应投足营养价值高且较全面的饲料,有条件的可增喂一些蝇蛆、泥鳅等,保证牛蛙吃饱吃好,以便蓄积冬眠所需的养料,
Bullfrog is a warm-blooded animal, when the water temperature dropped to 6 ~ 12 ℃ began to hibernate. This period management should pay attention to the following three points: First, before the winter to protect the bullfrog into hibernation, lurking in the bottom or caves do not eat, relying on skin oxygen in the breathing water and the accumulation of nutrients to maintain low micro metabolism. Therefore, we should pay close attention to the hibernation before hibernation, should be cast daily nutritional value of high enough and more comprehensive feed, conditional feeding some fly maggots, loach, etc., to ensure full eating bullfrog, in order to accumulate the nutrients needed for hibernation ,
