摘　　要：Julia语言是高性能、动态编译的高级计算机语言,具有极强的灵活性,适合于解决数值和科学计算问题,拥有与传统的静态型语言相媲美的执行速度,Julia语言的开发目的是创建一个功能强大、易用性好和高效的单一语言环境。在动物育种中使用Julia语言可以编写语法简洁,且运行速度接近于Fortran或C++编写的程序。该文提供了7个动物育种中常用程序的Julia代码及示例,包括计算分子血缘相关矩阵(A)、分子血缘相关逆矩阵(A-)、近交系数、设计矩阵、分块矩阵,混合模型方程组(MME)和基因组关系矩阵(G)。这些代码可以为编写动物育种实用程序及相关教学活动奠定基础。Julia is a high-performance, high-level dynamic programming language for technical computing.It is a flexible dynamic language, appropriating for numerical and scientific computing,with execution compara- ble to traditional statically-typed languages.Julia aims to create an quite unusual combination of power, ease-of-use,and efficiency in a single language.The reasons why I have a preference for Julia in animal breeding are ：speed and nice syntax.The paper offers 7 source codes in research of animal breeding,includ- ing calculating additive relationship matrix or numerator relationship matrix（A）,inverse of additive relation- ship matrix（A-）,inbreeding coefficient,design matrix,block or direct matrix,mixed model equation（MME）, and genomic relationship matrix coefficients（G）.These programs can be used as a basis for practices of ani- mal breeding and also used for education in animal science.
