第一部分:需要额外补钙吗???兽医学博士Ron Hines写过一片文章讲如何照顾怀孕哺乳期母狗~~原文在这里: http://www.2ndchance.info/pregnantdog.htm 在他的文章中提到~~食物是与平时一样的(母狗胃口不好时除外)~~不同的只有量~~~其中还调强一句"There is no need to give a vitamin or mineral supplement."还有很多外文网站在写到这个问题时,意见和兽医学博士Ron Hines都是相同的~~~因为没写作者~~我就随便挑几句:1 Calcium is one supplement that deserves some special attention. Supplementing a pregnant dog is definitely not recommended. 2 Although it is true that a female's need for calcium increases during pregnancy and lactation, supplementing with calcium is not necessary.3 do not supplement your pregnant dog with calcium unless specifically instructed by your veterinarian.4 Don't give your dog vitamin or mineral supplements, especially calcium supplements所以,无需额外给母狗补钙了~~~第二部分:小狗生长所需要的这么多钙质~倒底从峡肆峡哪里来???看文章: http://www.superk9.com/article-dogfoodnutrition08.asp 文中提到:When a female is nursing, there is an increased demand for calcium. The bones provide an abundant resource, but the withdrawal of calcium from the bones depends on several hormones. 所以说骨头是钙"银行"~当钙多的时候~一部分钙会存到"银行"里当钙不够的时候,一部分钙会从"银行"里务孟提出来~~母狗在怀孕哺乳期~~很需要钙~~因此~这时体内会分泌激素激素在体内激活一系列的生化反应从而把钙质从骨头里提取出来.当怀孕哺乳期后,狗狗又能从食物中吸收钙质~很快就会恢复 第三部分:为什么不能大量补钙补钙???有什么风险??过度补钙会抑制体内激素的分泌~~破坏体内调钙能力~~让母狗依赖人给崇坐她补的钙,一旦补得不够~钙质又无法及时从骨头中分离出来~这时母狗血钙含量就降低~~血钙含量过低的话~对母狗有生命危险!!!!因为钙不仅组成了骨头~还参与了体内很多的生化反应肌肉的每一下收缩,包括心脏的每下跳动都和钙有关~~低血钙的后果可想而知~~~可能会让母狗(特别是小型犬)抽搐到死~~此外~钙过多的话~~还可能让母狗难产~对小狗狗也骨骼也不好,因为1钙会沉积在幼犬软组织里~2钙过多让幼犬关节发育不正常
