[Energy and protein supply for event horses during training: comparison between intake and requirements].

This research study investigates the dietary energy and protein intake of event horses during training, observing that the intake exceeds the estimated requirements, raising concerns about the estimation strategies for energy and protein requirements for such horses.

Overview

In this research, the investigators closely examined the energy and protein consumption of event horses – horses trained for physically demanding events. They compared the horses’ intake with their estimated energy and protein needs based on their training routines. They found a discrepancy with the horse’s energy and protein consumption being higher than their estimated needs. With the horses maintaining stable body weight, the study questions the accuracy of estimating strategies for dietary requirement in horses.

Methodology

• The investigators utilized a diet record to observe the energy and protein intake of the horses over a seven-day period. The results were then compared with estimates of energy required for exercise.
• The sample population for this research consisted of event horses undergoing intensive training. The sample size of the study was 15 horses.

Findings

• Daily net energy intake of the horses was 30% higher on average than the estimated net energy requirement for exercise.
• In addition, the intake of digestible protein was found to be 92% higher than the estimated protein requirement.
• Despite this excess intake, the horses maintained constant body weight, indicating an energy balance.
• This created a situation where the actual energy and protein intake were either overestimated or the requirement were underestimated.
• The researchers believed that these findings highlighted a significant problem with the current methods for assessing and evaluating rations for horses, especially those in heavy training.

Implications

• This research raises concerns about the way energy and protein requirements are estimated for horses, particularly those undergoing rigorous training.
• The study highlights the need for more accurate methods of estimating dietary needs to ensure the health and performance of horses involved in intensive exercise.
• As a misuse of energy and protein supplies in horses can have significant health implications, this study’s findings suggest that dietary programs for training horses might need revision and optimization.
