龟鳖与禽鸟类一样,靠产卵繁衍后代,其卵壳富含钙质,如钙缺乏,会形成软壳卵,而软壳卵极易弄破,不能孵出幼仔。 钙在龟鳖机体内,以集中在骨骼和牙板中,参与骨骼与血液组成。如钙不足,会使牙板和骨骼发生钙转化障碍,肌肉神经失去正常兴奋性,所产之卵变成软壳卵,失去孵化利用价值。 亲龟亲鳖不缺钙时,所产卵的外表为
Turtle turtles and birds, multiply offspring by laying eggs, the egg shell is rich in calcium, such as calcium deficiency, the formation of soft-shelled eggs, soft-shelled eggs and easy to break, can not hatch young. Calcium in turtle body, to focus on bone and dental board, to participate in bone and blood composition. Such as calcium deficiency, will make dental board and bone calcium conversion disorders, loss of normal excitability of the muscle nerves, the eggs produced into soft-shelled eggs, loss of hatch utilization value. Pro-turtle pro-turtle is not calcium, the appearance of the eggs
