Assessment of the importance of some physiological indexes at definition of stressful sensitivity of hens

One of the approaches, to preventive maintenance of a stressful state of auks selection on degree of order to stresses can be promoting. For an assessment of stressful sensitivity it is offered turpentine the test allowing by modelling of a local adaptation syndrome to divide auks on two bunches – steady and sensitive to stresses. For studying of physiological features of meat hens with different stressful sensitivity the assessment of a representativeness of the separate indexes reflecting a state stress-realising of systems of an organism and the general strain has been made. For an assessment of stressful sensitivity the greatest value has interrelation G/L defined in 30 minutes after intradermal introduction of solution of turpentine. Depending on number of auks in bunch and tasks in view on the basis of this sign it is possible to range indexes and on the basis of it to define subtotals of stressful sensitivity of hens. As specifying indexes it is possible to use concentration definition in blood of stressful hormones and time of tonic immobility of hens.
