Abstract

The objective of this study was to determine whether birth order influences piglet survival because of reduced uptake of maternal antibodies by the piglets born later in large litters. Forty-five litters were serially allocated to one of 2 study groups. The crèche group consisted of 18 litters for which the 205 piglets were removed to a warm box to prevent suckling until 4 h after delivery of the first pig, and the control group of 27 litters for which 306 piglets were allowed to suckle from birth. The protein content of piglet blood and sow colostrum was determined with Brix refractometers. Parity, farrowing duration, liveborn litter size, litter size at 12 d, and piglet weight at birth and at 24 h and 12 d of age did not differ between the 2 treatment groups (P > 0.1). There were also no significant differences (P > 0.1) at any time point in weight or in the mean percent protein in plasma between the first 3 and the last 3 piglets born to an individual sow. However, the mean percent protein in plasma was significantly higher in the control group than in the crèche group at both 24 h (P ≤ 0.05) and day 12 (P ≤ 0.01) postpartum. The lack of differences in plasma protein levels between the first and last pigs born along with the...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.
