Animal Line

LINE OF ANIMALS

**Line of animals (syn. L. inbred, L. pure)** is a special type of line in which all descendants are obtained by crossing individual pairs with each other in order to consolidate the characteristics necessary for the breeder in the resulting offspring.

The concept of “animal line” does not have a precise definition in legislation. However, the term is widely used in animal husbandry to refer to groups of genetically related animals with certain characteristics. This article will discuss the features of using lines in the process of raising animals, their advantages and disadvantages, as well as examples of real projects using lines.

1. Advantages of animal lines - Planned, thoughtful, artificial breeding of a line allows you to obtain certain characteristics in the offspring when crossing two organisms without changing their race and the general set of chromosomes. Thus, this feature of the lines can be used by breeders to create new breeds that are more productive and resistant to disease. - By using pure lines, a farmer can ensure complete genetic variation by controlling the ability of parents to pass on their traits to subsequent generations. Thanks to this, he can see the exact direction of the genetic development of his animals. This makes it possible to quickly monitor any deformations and, if necessary, adjust parameters to achieve optimal values. For example, growth rate indicators, hair quality
