Displacement of the tubular genital tract of the ewe during pregnancy

The Veterinary Record
E Ayen, D E Noakes

Abstract

The displacement of the tubular genital tract of ewes during pregnancy, in particular of the cervix relative to the cranial pelvic brim, was studied by sequential radiography using radio-opaque markers attached surgically before tupping. In the first year, 13 two-year-old parous ewes were fed a complete pelleted diet containing either 15 or 25 per cent fibre throughout pregnancy. The distances between the markers attached to the tubulogenital tract increased and the distance between the cervix and the cranial pelvic brim increased slightly with advancing pregnancy; the diet had no effect. In the second year, only cervical displacement was studied in 11 ewes that had suffered a cervicovaginal prolapse the previous year, and in five of their female progeny. They were divided into two groups, one of which was fed a 15 per cent-fibre complete pelleted diet and the other hay ad libitum throughout pregnancy. In two ewes, one from each dietary group, the prolapse recurred less than two weeks from term; initially it was a stage 2 prolapse, where the vaginal wall fails to return to its normal position when the ewe stands, but in one ewe it became a stage 3 prolapse, with the vagina completely everted and the cervix visible. During the s...Continue Reading

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.
