摘　　要：为了研究哺乳动物生殖对策,以母猪生殖记录为研究对象,对母猪不同胎次间产仔数的变化等进行研究。研究发现,在母猪的不同胎次间存在一定规律。通过优化每次繁殖过程所产生后代的数量,结果将身为发现哺乳动物对外界环境的感知和自适应机制奠定基础。Inorder to studymam malian reproductive strategies,we studied the sow reproductive records,which contained the research of different parities between litter size of sows change and so on.This study found that existing strategies indifferent parity sows,and sows will optimize the offsp ringnumber of each breeding process.The results will lay the foun-dation for the discovery of mammalian perception and adaptive mechanisms for the external environment.
