Featuring long-loop tournaments: breeding and training profiles and blood changes in criollo horses before and after exercise.

Abstract: Long-loop rodeo is a major competition for Criollo horses. We aimed to feature long-loop tournaments and to assess the profiles of competing horses. The animals (n = 49) were registered, and their body mass/scores, information about breeding, feeding, and training management, loaded weight, and tournament track (n = 11) were collected; speeds reached were estimated. Heart and respiratory rates of horses (n = 27) were collected before the tournament, on the final day of the event, and 18-24 h after the end of the tournament. Blood samples were collected from the animals at the same time. Blood count (n = 19) and biochemical profile (n = 28) were conducted based on total proteins, albumin, globulin, phosphorus, sodium, potassium, urea, creatinine, glucose, triglycerides, and cholesterol. Data were assessed using analysis of variance in association with Tukey's test (P ≤0.05) and Spearman's correlation (P ≤0.05). Most horses were bred in a semi-stable system, fed roughage and concentrate, and subjected to non-standardized training. The tournament comprised a high-intensity and short-duration exercise with a mean speed of 6.44 m/s, during which the horses carried 25.59% of their body weight on their backs. Clinical evaluations and hematological and biochemical assessments in this study showed physiological changes caused by exercise. O rodeio de laço comprido é uma das principais competições em que o cavalo Crioulo participa. O objetivo deste trabalho foi caracterizar a competição e o perfil dos equinos competidores. Foram cadastrados os animais (n=49) com a mensuração de massa e escore corporal e coletadas as informações sobre criação, alimentação e treinamento, peso do cavaleiro e da sela, dados da pista (n=11) e velocidade estimada dos animais. Nos tempos: 24 horas pré-prova, após a última corrida do último dia de prova e entre 18 a 24 horas após o final da prova, foram aferidas as frequências cardíaca e respiratória dos equinos (n=27) e a temperatura ambiente, foram coletadas amostras sanguíneas dos animais nos mesmos tempos para realização de hemograma (n=19) e bioquímicos (n=28) abrangendo proteínas totais, albumina, globulina, fósforo, sódio, potássio, ureia, creatinina, glicose, triglicerídeos e colesterol. Os dados foram avaliados por análise de variância associada ao teste de Tukey (P ≤0,05) e submetidos à correlação de Spearman (P ≤0,05). Os equinos eram, majoritariamente, criados em sistema de semi-estabulação, alimentados com volumoso e concentrado e com treinamento não padronizado. A prova mostrou-se um exercício de alta intensidade e curta duração, em pistas de areia, com velocidade média de 6,44 m/s e os equinos carregaram 25,59% do seu peso corporal. As avaliações clínicas, hematológicas e bioquímicas demonstraram alterações fisiológicas causadas pelo exercício, indicando aptidão.

This research focuses on understanding the profiles of Criollo horses participating in long-loop rodeo competitions, their training and feeding patterns as well as analyzing physiological changes in their bodies before and after the event.

Overview

The study was conducted with 49 registered Criollo horses that took part in long-loop rodeo competitions and were subjected to measurements of body weight and score. Relevant information regarding their breeding, feeding and training patterns was collected. The tournament’s effects on the horses, in terms of physiological changes, were also analyzed.

Methodology

  • The horses were studied in various stages: 24 hours prior to the tournament, immediately after the last race on the final day, and between 18 to 24 hours after the event’s conclusion.
  • Vital signs including heart rate, and respiratory rate of the horses were recorded.
  • External conditions like ambient temperature were also noted down.
  • Blood samples from the horses were collected in tandem with the time of their physical evaluations. The samples were utilized to perform a complete blood count (n = 19) and biochemistry profile (n = 28).
  • The biochemistry profile captured key metrics like total proteins, albumin, globulin, phosphorus, sodium, potassium, urea, creatinine, glucose, triglycerides, and cholesterol.
  • Data from the study was evaluated using an analysis of variance in conjunction with Tukey’s test (P ≤0.05) and Spearman’s correlation (P ≤0.05).

Findings

  • Most of the horses were born and raised in a semi-stable system.
  • They were typically fed roughage and concentrate, and their training was not standardized.
  • The tournament was found to comprise of high-intensity, short-duration exercise with the horses carrying an average of 25.59% of their own body weight.
  • The mean speed reached by the horses on the sand tracks was 6.44 m/s.
  • Physiological evaluations, along with hematological and biochemical assessments, showed significant changes caused by the strenuous exercise, indicating fitness.
