SOME BEHAVORAAL CHARACTERISTICS OF DOMESTIC SHEEP X BIGHORN (OVIS NIVICOLA) HYBRIDS

One of hybridization objectives is to improve adaptive traits in domestic animals to certain conditions. When hybridizing, new livestock breeds including sheep were produced. Behavioral characteristics and habits are transferred from parents to the hybrids obtained. Herein, it is to be noted that wild species when crossed with domestic sheep can pass on not only beneficial, but also undesirable traits to offspring. The undesirable traits may be referred to as late maturity, poor technological qualities of wool, wildness, fearfulness and aggression. Therefore, to study behavioral responses of F1 hybrid lambs in the early postnatal period and reveal possible training with imprinting and individual experience of the animals’ impressions will allow to identify the hybrids’ ability to get accustomed to man, escape stress situations and reduce the number of injury cases caused by needless wildness or fear. Keeping the hybrid offspring under the conditions maximally close to wild forms’ natural dwelling and those of minimized contacting man make for animals show up undesirable behavioral forms, such as fearfulness, alertness and aggressiveness. The conditions maximally close to domestic sheep housing with hybrid biological characteristics considered were created for the hybrids: Besides, mountain landscape was simulated to support active mobility of the hybrids. Close and continuous contact between the hybrid offspring and man is the principle point to achieve the goal.
