Abstract: Albino (s(al-c)) and non-albino (colored) hens from the same origin were compared for several plasmatic hormonal levels (triiodothyronine (T3), thyroxine (T4), growth hormone (GH), and corticosterone) before the onset of laying and after 3-4 months of production. The T3/T4 ratio was higher among albino than among non-albino females at the 2 ages; this difference approached significance after sexual maturity. The within-genotype variance of this ratio was higher for s(al-c) hens than for non-albino ones (P<0.01). On the other hand, the GH level did not differ between the 2 genotypes before the onset of laying, but during laying it was significantly higher for the s(al-c) females. There are therefore some differences in the general hormonal balance of the 2 genotypes. It is hoped that this may help in an interpretation of the effects on egg production associated with the albino gene.
