Abstract
The Oravka tawny is a Slovak national breed of chicken. This breed has combined utility, which means it is valuable for both its meat and eggs. The Oravka tawny is linked to a specific region, Orava, and therefore these products could be protected by European geographical indication. The labeling and sale of chicken meat by the traditional breed of origin are widely used to promote quality and attract those products in the marketplace. For that use, we created the system and method of authentication that can reliably distinguish between the Oravka tawny, other chicken breeds, and other of Oravka”™s colorful characters. In our research, we analyzed 153 chicken feathers from the Oravka breed as well as from breeds used in the process of breeding the Oravka to their current state. They were divided into nine populations. To separate those populations, we used seven microsatellite markers recommended by FAO (Food and Agriculture Organization) and other authors. To create separate clusters of individual breeds, we used DAPC (discriminant analysis of principal components) analysis.
Highlights
By the term food authentication, we understand the process of verifying that the label description of the food is accurate and contains all the necessary information for customers
Scientific hypothesis We are expecting that separation of the Oravka breed from other chicken breeds used in its breeding process will be possible with the usage of chosen microsatellite markers
A structured genetic analysis program based on microsatellite markers was used to investigate the genetic structure of the five Korean native chicken lines
Summary
By the term food authentication, we understand the process of verifying that the label description of the food is accurate and contains all the necessary information for customers. We are aiming to protect national breed and preserve biodiversity of Oravka tawny chicken. We are aiming to create a useful method of authenticating products made from the Slovak national chicken breed – the Oravka tawny.
