Cadmium and the laying hen: apparent absorption, tissue distribution and virtual absence of transfer into eggs.

Poultry Science
J L Sell

Abstract

After being given a single oral dose of 40 muCi. of 109CdCl2, laying hens were fed a practical type ration to which 0 or 60 p.p.m. cadmium (Cd, as CdCl2) was added. On the basis of 109Cd in excrement, apparent absorption of the isotope averaged less than 10% of the dose for both diets. Less than 4% of the dose was retained in total body tissue 23 days after dosing. Dietary Cd level did not significantly influence excretion of 109Cd by hens, but hens fed 60 p.p.m. Cd retained a significantly higher proportion of 109Cd dose in liver, kidneys and whole body than did control hens. 109Cd was only detected in blood 48 hours after dosing and more than 75% of radioactivity in the blood occurred in plasma. Hens fed 60 p.p.m. Cd consumed less feed and produced less eggs than control hens. 109Cd was found infrequently at very low levels in yolks of eggs produced by hens fed 60 p.p.m. Cd. No radioactivity was detected in any egg whites, or in yolks of eggs produced by control hens.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
