Why is genetic selection important in animal breeding?

Genetic selection is crucial in animal breeding because it targets specific traits that enhance the overall performance and wellbeing of livestock. The approach allows breeders to choose individuals with desirable characteristics—such as improved growth rates, enhanced feed efficiency, better reproductive performance, and greater resistance to diseases. By selecting for these traits, breeders can produce offspring that not only grow faster and healthier but also require less feed input relative to their body mass, ultimately leading to improved productivity and sustainability in animal agriculture.

Selecting for traits related to health and disease resistance is particularly important, as it can lead to healthier herds and flocks, reducing the need for medical interventions and potentially lowering production costs. This selective breeding creates a cumulative effect over generations, resulting in animals that are more productive and better adapted to their environments, which is vital for meeting increasing food demands. Through this method, genetic selection plays a significant role in ensuring the success and efficiency of animal production systems.
