Experiments with Animal Protein to Laying Fowls.

Transmission Experiments with Leucosis of Fowls

It is shown, in a carefully controlled experiment, that fowl leucemia can be readily transmitted from chicken to chicken by injection. Of 25 fowls, 13 were injected intravenously with blood from a chicken (No. 575) with erythroleucosis and 12 with blood from a chicken (No. 689) with myeloid leucosis. The injected birds and an equal number of uninjected controls were kept in tiers of alternating...

Growth and Reproduction in Fowls in the Absence of Carotinoids and the Physiological Relation of Yellow Pigmentation to Egg Laying.

Relevance of animal experiments to humans.

The best evidence of an adverse human health effect is a properly conducted epidemiological study. But human beings should not be the sole test animal. Properly conducted animal studies have been shown to be preductive for carcinogenicity and toxicologic responses in human populations. We need to develop more efficient predictive animal tests for all the common serious toxic effects caused by c...

New thinking on animal experiments

National regulations on animal experiments vary widely between countries but growing numbers of researchers in Britain believe that the procedures are in need of an overhaul. And a new report by a group of members of Britain’s upper house of parliament, the House of Lords, advises a shakeup that both speeds up consideration of researchers’ requests but opens up public scrutiny of such work. The...
