Abstract

The effects of supplemented selenium and vitamin E on a number of rumen parameters such as the population of rumen protozoa, pH, concentration of volatile fatty acids and ammonia nitrogen in the rumen content were studied. Eight lambs were randomly allocated into two groups: a control group and an experimental group receiving vitamin E (DL-alpha-tocopheryl acetate, 250 mg/kg of feed) and selenium (sodium selenite, 0.3 mg/kg of feed) supplementation. Samples of rumen content were taken from all lambs three times daily once a week (before feeding as well as 3 and 6 h after feeding) over a period of 10 consecutive weeks. In addition, the lambs were weighed at the end of experiment. The total counts and percentage proportions of rumen protozoa, the pH value, and the levels of ammonia nitrogen and volatile fatty acids were determined in the samples of rumen content. The levels of acetic acid, propionic acid, butyric acid and total volatile fatty acids, the total counts of protozoa, and the percentage proportion of Diplodinium were found to be significantly higher in the supplemented than in the control group (P < 0.05, P < 0.01), whereas the pH values and the percentage proportion of Dasytricha ruminantium were significantly lower i...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.
