Avian Thyroid: Effect of p,p'-DDT on Size and Activity

D. J. Jefferies 1 and M. C. French 1

1 Monks Wood Experimental Station, Abbots Ripton, Huntingdon, England

Feeding sublethal amounts of p,p'-DDT to pigeons caused an increase in thyroid weight and a reduction in colloid content of the follicles. This may reflect a hyper- or hypo-functioning gland and may be cotnnected with recent reductions in egg shell weights in wild birds. The effect was accompanied by increased liver weight.
