Effects of the duration of lairage following transportation on the behaviour and physiology of farmed red deer

The Veterinary Record
P N GrigorP D Warriss

Abstract

Eight groups of five farmed red deer were transported by road for three hours, after which they were either slaughtered immediately (TO) or held in lairage for three, six or 18 hours (T3, T6 and T18). Liveweight loss increased with lairage time but hot carcase weight was unaffected. Deer spent much of the initial period in lairage standing stationary in 'alert' postures. After eight to 10 hours the proportions of time spent in various postures (standing stationary, moving and lying down) were similar to pre-journey values. None of the blood components associated with dehydration (packed cell volume, osmolality, total protein and sodium) changed significantly with lairage time. Compared with T0 deer, plasma creatine kinase activity was significantly decreased in T18 deer. Lairage time had no effect on skin damage, bruising or muscle glycogen content, although liver glycogen content increased with longer lairage time. Although lairage time had a statistically significant effect on muscle pHu (with T6 deer having the lowest values), the differences were small and none of the carcases had a pHu greater than 6-0.

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.
