Abstract The influence of low humidity during incubation (LHI) on arginine vasotocin (AVT) secretion in male and female White Leghorn chicken embryos and chicks was investigated. LHI embryos were incubated from day 8 (E8) to E18 at a relative humidity of 32–35%, while control embryos were incubated at 58–62%. In the control groups, plasma AVT gradually increased from E15 to E18, increased sharply during hatching and returned to the El8 level within 4 h. LHI did not alter the level of AVT until E18. LHI E19 males had concentrations of AVT twice as high as those of control males (39 ± 3·9 vs 15 ± 1·6 pmol/l, P<0·001). Augmentation persisted during hatching and 4 h afterwards. In LHI females additional elevation reached significant levels only at 4 h after hatching (58 ± 13 vs 16 ± 1·7 pmol/l, P<0·01). Deprivation of water caused an increase in plasma sodium concentrations in the 2-day-old chicks of the control groups, while no significant changes were observed in the LHI group. Deprivation of water together with a high environmental temperature caused an additional increase in AVT only in the LHI groups (42 ± 5·2 vs 22 ± 3·9 pmol/l, P<0·01 for males; 32 ± 3·4 vs 19 ± 2·8 pmol/l, P<0·01 for females). The results clearly showed that LHI leads to a more pronounced response of the AVT system on subsequent osmotic and non-osmotic challenges, especially in males. Embryonal activation of the AVT system probably helps the organism to cope with hatching and posthatching stresses. Journal of Endocrinology (1994) 142, 153–160

1. A three-year study was conducted to test the efficacy of inter- and intra-specific blood transfusions in domestic poultry for inducing heritable changes in the recipients. The latter were pure-bred White Leghorns. Pure-bred Broad Breasted Bronze turkeys and New Hampshire chickens served as blood donors to two distinct lines of recipients. All injections started when the recipient chicks were 2–5 days old. Altogether, more than 3000 chicks from blood injected lines were involved in the study, conducted between 1959 and 1961 and distributed between the parental and three subsequent generations. Each injected chick received a total of some 155 ml. of whole blood in the course of a five-month injection period. An adequate number of control (non-injected) birds was used throughout. Observations were made on plumage colour, body-weight, egg-weight, egg-shell colour, fertility and hatchability. Furthermore, blood plasma and muscle tissue of appropriate birds were subjected to immunological, chromatographic and electrophoretic analyses.2. On the basis of all these criteria, no evidence of heritable shifts in the direction of the donor organism was discerned among birds belonging to either of the two treated lines.
