The articles is about the history of animals breeding. Which has a very long history in which farm animals where breed for human benefits. Using a process called selection, in the articles selection refers to the genetic improvement of animals with artificial selection. Recently the practice of animal breeding has become more sophisticated, increasing the speed of production traits. For example, the rate of growth (increased) in animals. However there’s also been some well documented evidence of negative fertility and health issues in high yielding dairy cattle. The author of this article is trying to explore the questions surrounding breeding and welfare. Concluding that there is a better need for an understanding of genotype and the environments effect on health and welfare traits in order to get breeding programs to improve environmental fit in animals.
