Effects of silage diets on health, reproduction, and blood metabolites of dairy cattle.

Abstract

Forty-eight Hostein dairy cows were assigned uniformly by parity and calving date to three forage treatments for three lactations. Forage treatments were corn silage (F-I), corn silage plus Hay-crop silage (-f-II), and corn silage plus hay (F-III). Records of health and reproductive data were kept to evaluate dietary effects. During the third lactation six animals in each treatment were blood-sampled on a 4-day interval from 24 days prepartum to 60 days postpartum to determine metabolites. Reproductive traits were similar among the treatment groups as were occurrences of mastitis. Corn silage and hay-crop silage cows had more ketosis than hay cows. Corn silage cows had more parturient paresis than the other two groups, and abomasal displacement occurred only in the corn silage group. There were differences in concentrations of plasma metabolites among treatments; however, they appeared to be within normal ranges, and no pathological implications were obvious. Blood pH, blood packed cell volume, blood alkaline reserve, and pH values were similar among treatment groups. Histological evaluation of hepatic and endocrine tissues revealed no treatment effects.

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.
