Effect of genetic selection on growth parameters and tonic immobility in Leghorn pullets.
Four genetic stocks of Leghorn pullets were used to evaluate the effects of genetic selection on growth and fearfulness behavior. Three of the stocks were the Ottawa randombred control stocks from 1950 (CS5), 1959 (CS7), and 1972 (CS10). The fourth stock was a 1993 commercial laying stock (CCS) whose ancestors were involved in the formation of the randombred control stocks. Pullets were reared ...
متن کاملAdrenocortical responses of Japanese quail to a routine weighing procedure and to tonic immobility induction.
Tonic immobility (TI) is induced by brief manual restraint, and it is a commonly used test of fearfulness, particularly in poultry. However, in view of increasing ethical concerns about experimentation on living animals, there is a need to ensure that the tests used do not elicit unacceptable distress. In the United Kingdom, there is some debate as to whether TI should be classified as a regula...
متن کاملTraumatic events and tonic immobility.
Tonic immobility is a basic defense strategy which has not been studied in depth in humans. Data suggest that it may be a relatively frequent phenomenon in victims of rape and sexual abuse, but its occurrence has not been systematically explored in other types of trauma. We carried out a retrospective study in a sample of 100 university students to establish whether tonic immobility varies depe...
متن کاملEvaluation of tonic immobility in common pheasant hens kept in different housing systems during laying period
Common pheasant (Phasianus colchicus) hens kept in different housing systems during laying period were exposed to a tonic immobility test. At the end of the laying period, the shortest duration of the tonic immobility, and thus the lowest fear level, was found in birds kept in enriched cages, i.e. cages equipped with 2 perches and a hiding place. The duration of the tonic immobility in hens kep...
