Hematological and biochemical values in Breton breed horses in Brasília-DF.

Abstract: Due to the scarcity of information on Breton horses, the objective was to study hematobiochemical values of this breed. Blood samples were collected from 29 Bretons, males and females, of different ages, in Brasília-DF, distributed into groups, according to age, without distinction of sex (G1): animals from 4 to 9 years old (n=16) and (G2): from 10 to 26 years old (n=13). The horses were also distributed into males and females for comparisons between the sexes. Values for red blood cells, hemoglobin, creatinine, and urea were statistically higher in females. Fibrinogen was higher in males. Lymphocyte values were higher in G1, but mean corpuscular volume, monocytes, neutrophils, and GGT in G2 were higher than G1. The hematocrit value differed between the ages of the females and was higher than that of the males, while the older male animals showed higher values than the young animals. Females presented lower platelet values than males, with older females having higher platelet values than younger females, in the same way as males. G1 females had the highest leukocyte values. The leukocyte values in males of G2 were higher than those of G1. This same behavior occurred for lymphocytes, eosinophils, and creatine kinase. Considering the albumin and aspartate aminotransferase variables, females had the highest values in the group of animals aged 4 to 9 years. Bretons are considered cold-blooded animals, which is consistent with the observed blood count values. However, it is concluded that these horses have biochemical values similar to warm-blooded breeds. Devido à escassez de informações sobre equinos da raça Bretão, objetivou-se estudar valores hematobioquímicos da raça. Foram coletadas amostras de sangue de 29 Bretões, machos e fêmeas de diferentes idades, em Brasília-DF, distribuídos entre grupos, segundo idade, sem distinção de sexo (G1): animais de 4 a 9 anos (n=16) e (G2): de 10 a 26 anos (n=13). Os mesmos também foram distribuídos em machos e fêmeas para comparação entre os sexos. Valores para hemácia, hemoglobina, creatinina e ureia foram estatisticamente maiores nas fêmeas. Fibrinogênio foi maior nos machos. Valores de linfócitos do G1 foram maiores, mas o volume corpuscular médio, monócitos, neutrófilos e GGT do G1 foram menores que do G2. Valor do hematócrito difere entre idades das fêmeas e foi superior ao dos machos, os animais machos mais velhos apresentaram valores superiores aos jovens. As fêmeas apresentaram valores de plaquetas menores que os machos, sendo que as mais velhas apresentaram valores de plaqueta maiores que as mais jovens, da mesma forma que os machos. No G1, as fêmeas apresentaram os maiores valores de leucócitos. Os valores de leucócitos nos machos do G2 foram maiores que os do G1. Esse mesmo comportamento ocorreu para linfócitos, eosinófilos e creatinaquinase. Já para as variáveis albumina e aspartato aminotransferase, no grupo de animais de 4 a 9 anos, as fêmeas tiveram os maiores valores. Bretões são animais de sangue frio, o que condiz com os valores do hemograma observados. Porém, conclui-se que estes equinos apresentam valores bioquímicos similares aos de sangue quente.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research examined the hematological (blood-related) and biochemical values in a breed of horses known as Bretons, exploring variations across age and gender, with the aim to expand the limited information available about this breed. It found that these so-called ‘cold-blooded‘ horses had blood count values commensurate with their categorization, but displayed biochemical values similar to warm-blooded breeds.

Methodology

  • Blood samples were collected from a total of 29 Breton horses of varying gender and age, in Brasília-DF.
  • The horses were groups based on age: 4-9 years old (16 horses) and 10-26 years old (13 horses). No distinctions were made based on gender in this age grouping.
  • The researchers also made a separate comparison of blood samples based on gender.

Findings

  • Results showed statistically higher values for red blood cells, hemoglobin, creatinine, and urea in female horses.
  • Fibrinogen levels, on the other hand, were higher in male horses.
  • When comparing age groups, lymphocyte values were higher in the younger group, while mean corpuscular volume, monocytes, neutrophils, and GGT in the older group were higher.
  • Hematocrit value, the volume percentage of red blood cells in blood, differed between the females of different age groups and was higher compared to the males.
  • However, older male horses had higher hematocrit values than their younger counterparts.
  • Females exhibited lower platelet values than males, but older females had higher platelet values than younger females, echoing the pattern observed in males.
  • In the younger group, females had the highest leukocyte (white blood cell) values.
  • For the older group, males had higher leukocyte values compared to the younger group, a pattern that was also seen in lymphocyte, eosinophil, and creatine kinase values.

Conclusion

  • Despite Breton horses being classified as cold-blooded animals, the blood count values identified in the study align with this classification.
  • Remarkably, the researcher found that the biochemical values of these horses showed similarities with those typically seen in warm-blooded breeds.
  • The research contributes valuable new data to the limited body of knowledge on Breton horses.
