Inheritance of the type of behavior in farm sables

Abstract

Purpose: studying inheritance of the type of behavioral reaction in farm sables.Materials and methods. To determine the nature of the behavior of animals, the reaction of animals to the presentation of an external stimulus (“test on a stick”) was evaluated. According to the results of testing sables, one of the three categories was attributed to one of the three categories: calm (friendly, coming to contact with a person), avoiding contact (cowardly, not responding to the subject) and aggressive (evil, negative reaction to humans). The following designations were used to differentiate animals: “0”-avoiding contact, “+”-calm and “- ”-aggressive. The results of reproduction of 925 heads of the main herd are taken into account. Analyzed 9 types of selection of steam (3 homogeneous and 6 heterogeneous) actually formed during the rut. 2290 puppies obtained at these types of selection were tested.Results. It has been established that with all 9 options for selecting steam in the offspring, puppies prevail with an assessment of “avoiding contact”: from 60.0 to 80.0%. The analysis of the type of puppy behavior was shown by the absence of clear laws inheritance of behavioral reactions in sables. The type of behavior, the “avoidance of contact” with a person prevailing in this type (60.4% in adult livestock and 72.3% in young animals), the descendants of the characteristics of the behavior of parents with all options for selecting pairs.
