种间杂交是利用不同种的动物进行杂交,但在畜牧业中广泛地进行种间杂交问题,则还是在开始。采用这种杂交方法的第一个目的在于获得能被利用的种间杂种,因为牲畜在杂交的情况下,往往能使后代生活力提高和对不同环境条件的适应能力加强。种间杂交不仅可以将两个杂交类型的特性结合在一起,同时还可以引起各种新特性的产生,因此种间杂交的第二个目的,是可以育成具有新品质的动物新种。在畜牧业的实践中,种间杂交往往会发生杂交后代的不能生育的现象,同时事实也是并不是任何种都可以和其他的种进行杂交,这是因为种与种之间在解剖、生理和生殖机能上有着差异,这些差异有时是很大的。种间不能进 Interspecific hybridization is the use of different species of animal hybridization, but in the livestock husbandry, interspecific hybridization is still the beginning. The first purpose of using this hybridization method is to obtain interspecific hybrids that can be exploited because, as a result of crossbreeding, livestock tend to have increased viability and ability to adapt to different environmental conditions. Interspecific hybridization can not only combine the characteristics of the two hybrid types, but also can lead to various new features. Therefore, the second purpose of interspecific hybridization is to breed new animal species with new qualities. In the practice of animal husbandry, interspecific crossbreeding often results in the non-fertility of crossbred offspring. At the same time, it is not the case that any species can be crossed with other species due to differences in anatomy, physiology and Reproductive performance differences, these differences are sometimes great. Can not enter between species
