Epidemiological survey, general blood biochemistry, and histological examination of slaughtered heavy horse breeds with hemorrhage in the adipose tissue in the crest of the neck.
Abstract: Fifty-four slaughtered horses were classified into groups having adipose tissue in the crest of the neck with or without hemorrhage (AH and NH groups, respectively). Blood biochemical tests (Alb, TP, T-bil, GOT, GPT, LDH, T-cho, and BUN) and an epidemiological survey (age, gender, weight, origin, breed, BCS, CNS, and hoof disease) were performed. T-bil tended to be high, while the other parameters were normal. Weight, BCS, and CNS were higher in the AH group (P<0.05). GOT was lower in the AH group (P<0.05). It was suspected that the horses in the AH group had lipomatosis. It was assumed that the adipose tissue of the horses in the AH group contained damaged capillaries, and inflammation was confirmed based on evidence of macrophages and lymphocytes.

The research aimed to identify possible causes and consequences of hemorrhage in the adipose tissue of horses in the crest of the neck, by collectively analyzing various factors such as blood biochemistry, breed, body weight, and investigating the possible connection with lipomatosis.
Research Methodology
In the study, 54 horses that were slaughtered were divided into two categories based on the existence of hemorrhage in the adipose tissue in the crest of their neck. These two were referred to as ‘AH’ and ‘NH’ groups respectively.
- The horses were subject to blood biochemical tests. The biochemical parameters under assessment were Alb (Albumin), TP (Total protein), T-bil (Total bilirubin), GOT (Glutamic-oxaloacetic transaminase), GPT (Glutamic pyruvic transaminase), LDH (Lactate dehydrogenase), T-cho (Total cholesterol), and BUN (Blood urea nitrogen).
- The study also included an epidemiological survey which examined the age of the horses, their gender, weight, where they originated from, their breed, their Body Condition Score (BCS), Cresty Neck Score (CNS), and the existence of any hoof diseases.
Research Findings
The study’s results brought forward the following observations and inferences.
- Total bilirubin (T-bil) levels tended towards being higher than normal, although the other parameters fell within the typical range.
- Compared to the NH group, the AH group of horses had a higher body weight, BCS, and CNS. All these parameters were statistically significant (P<0.05).
- The GOT (Glutamic-oxaloacetic transaminase) level was found to be lower in the AH group, which is a significant finding (P<0.05).
- Based on these findings, the researchers surmised that horses in the AH group likely experienced lipomatosis, a condition characterized by the excessive deposition of fat in the body.
- The researchers also proposed that the adipose tissue in the AH group horses possibly contained damaged capillaries. They asserted these suspicions were affirmed by signs of inflammation due to the presence of macrophages and lymphocytes.
