Abstract

It is difficult to maintain turkey semen quality after in vitro liquid storage and the problem is worsened by animal aging. Little is currently known about the effects of both reproductive period and strain on the preservability of qualitative characteristics of turkey semen during liquid storage. The purpose of this study was to evaluate the effect of the reproductive period of two commercial turkey strains on semen quality changes during in vitro storage for upto 48 h at 5 degrees C. Two different periods were considered: first period from 32 to 40 weeks of age and the second one from 44 to 52 weeks. Turkey males from either British United Turkeys (BUT) Big-6 line and Hybrid Large White line (Hybrid) were used. Semen pools of each tom strain were diluted with Beltsville Poultry Semen Extender (BPSE) and the motility, viability and membrane integrity of sperm were evaluated at 3, 24 and 48 h of liquid storage at 5 degrees C. The sperm concentration was significantly affected by period (P<0.01) and strain (P<0.05), with best values in first period and in the Hybrid semen. Besides also the motility, viability and membrane integrity during 48 h of storage were better (P<0.05) in the first period compared to the second one for bot...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.
