Influence of Short and Medium Distance Road Transport on the Acute Phase Proteins in Horses.

This research study investigates the impact of short and medium distance road transport on the stress levels in horses. The researchers used blood tests and mass spectrometry to measure changes in the horses’ production of certain proteins known to be associated with stress responses. They found that the distances they tested (50 and 300 kilometers) did not create enough stress in the horses to cause significant changes in the levels of these proteins.

Research Objectives

• The primary goal of the study was to determine if road transportation over distances of 50 and 300 kilometers would lead to changes in the levels of acute phase proteins (APPs), which are commonly associated with stress responses in animals.
• To measure these changes, the researchers conducted blood tests before and at various intervals after the road transport, and identified proteins in the blood using mass spectrometry.

Methodology

• The researchers chose two distances for their tests – 50 and 300 kilometers – to represent short and medium distance transport scenarios.
• Blood samples were collected at several times: before transport, immediately after the journey, and then 6, 24, 48, 72, 96, 120, and 144 hours after the end of the trip.
• The protein content of the samples was analysed using SDS-PAGE (a method for separating proteins) and the proteins were identified by mass spectrometry (MALDI-TOF).
• Statistical analyses were performed with the Minitab 17 software. A result was considered significant if the probability (P value) was less than 0.05.

Findings

• The researchers were able to identify a number of APPs in the samples, including α2-macroglobulin, ceruloplasmin, transferrin, albumin, α1-antitrypsin, haptoglobin, apolipoprotein alpha 1, and α1-acid glycoprotein.
• No significant differences were observed in the concentration values of these proteins between the 50 km and 300 km transport scenarios or between the pre- and post-transport measurements.
• This lead to the conclusion that the distances covered were not challenging enough to provoke an acute phase response in the horses, meaning they did not experience significant stress as a result of the transport.
