Animals Inbred

Inbreeding or inbreeding of animals is one of the most common selection methods used in animal husbandry to improve the genetic qualities of animals and increase their productivity. However, inbred selection can have negative consequences, such as a decrease in the immunity of animals, an increase in the likelihood of genetic diseases and a decrease in the viability of offspring.

Inbreeding occurs when closely related animals are crossed with each other. This may be the result of consanguineous marriages or the use of inbreeding animals.

One of the main disadvantages of inbred selection is that animals resulting from inbreeding have a higher likelihood of inheriting genetic defects that may appear in subsequent generations. This is because inbreeding reduces genetic diversity, making the animals more vulnerable to disease and other genetic abnormalities.

In addition, inbreeding can lead to a decrease in the viability of animals. Animals born from inbreeding may have health problems, including developmental disorders, immune disorders and other diseases.

Also, inbreeding can negatively affect animal productivity. Inbred breeding can result in fewer offspring, reduced quality of offspring, and reduced offspring size. This can lead to a reduction in production and a decrease in the economic efficiency of livestock farming.

To prevent the negative consequences of inbred crossbreeding, it is necessary to use methods aimed at increasing the genetic diversity of animals and reducing the likelihood of inbreeding. Such methods include the use of hybridization, interbreeding and other methods aimed at increasing genetic diversity.

In general, inbreeding is an effective method of animal breeding, but its use should be limited to avoid negative consequences on animal health and productivity.

An animal is called inbred or half-blooded if it is born from two or more individuals that are closely related to each other. A close relationship is one in which the inbreeding coefficient exceeds 5%. The degree of inbreeding can vary. If it is low, then it is necessary to evaluate the exterior and the ability to reproduce. Minor inbreeding includes animals that were not obtained from the closest blood relatives. This factor usually does not negatively affect the overall development of the animal. In such cases, the female’s fertility and productivity sometimes increase. Such producers have better quality offspring. The degree of inbreeding is higher than in previous cases, but does not meet high thresholds. This factor is also possible, but less likely. With such inbreeding, sometimes there is a decrease in resistance, a slowdown in growth and development, and other negative manifestations. The maximum negative effect occurs when the degree of close relationship is 75% or higher.
