“…However, the higher ash content in the intestinal tract of horses on the HS diet could be the result of lower amounts of ash absorption in the intestine as a direct consequence of the high amounts of starch fed in the diet [ 31 ]. On the contrary, the higher percentage of OM found in the sternal flexure, the pelvic flexure, the right dorsal colon and the rectum in the HF group could be related to the high fibre intake which has been reported to reduce the digestibility of OM [ 32 , 33 ]. Moreover, a diet*sex interaction was found in relation to the percentage of OM and ash content in the sternal flexure.…”

A high-starch vs. high-fibre diet: effects on the gut environment of the different intestinal compartments of the horse digestive tract

Background Horses are often fed high amounts of starch in their diets despite the well-established benefits of a fibre-based diet to promote gut health and animal welfare. The aim of the present study was to compare the effects of two different diets – one based on high amounts of starch (HS) vs. one base on high amounts of fibre (HF) – on specific parameters of the gut environment across different intestinal compartments of the horse digestive tract. To this end differences in the gastrointestinal environment between HS vs. HF fed horses were assessed in terms of dry matter, organic matter and ash content; the particle size distribution and volatile fatty acid composition were also investigated. Results Nineteen Bardigiano horses of 14.3 ± 0.7 months of age and destined to slaughter were divided into two group pens – one fed with high amounts of starch (HS; n = 9; 43% hay plus 57% starch-rich pelleted feed); vs. fed with high amounts of fibre (HF; n = 10; 70% hay plus 30% fibre-rich pelleted feed). Horses fed HS diet presented a higher dry matter content in the right dorsal colon. Moreover, they showed a higher organic matter and ash content in the sternal flexure, pelvic flexure, right dorsal colon and rectum. In these latter intestinal compartments, horses fed a HS diet also showed a higher proportion of particles retained on an 8 mm sieve and a higher proportion of particles that washed through the finest sieve (< 1 mm). Moreover, the total amounts of volatile fatty acids as well as valeric acid were found to be significantly higher in horses fed the HS vs. HF diet. Conclusions A high-starch diet causes significant changes in the horse gut environment. We observed an increase in the dry matter content in the right dorsal colon, as well as reduced particle sizes and an increase in the production of valeric acid in all the gut compartments studied. High-starch diets should be avoided in favour of fibre-based diets with the goal of safeguarding gut health in horses.

“…Such devices are widely accessible to a large part of riders (an accelerometer is present in the largest part of commercially available Smartphone), but no software is developed to study horse athletic activity at present. Among all methods proposed in international literature for the calculation of energy expenditure (EE) for exercise in horses [5], in particular the German system is strictly linked with indirect measurements, through HR monitoring:…”

Currently, the most accurate and non-invasive method used to assess energy expenditure (EE) in sport horses is based on heart rate (HR) monitoring. However EE assessment using inertial platforms has been lately discussed in human sports medicine. The objective of this study was to evaluate whether inertial platforms would be useful tools to assess EE in horses.Six show-jumping and riding school horses (Thoroughbred and warmblood) were equipped with a HR monitoring system and a wireless inertial platform. Acceleration, HR and speed were measured during the exercise protocol that included walk, trot, canter and a sequence of 4 jumps. Stride maximum and minimum acceleration, and acceleration amplitude and root mean squares (RMS) were determined. Energy expenditure and oxygen uptake (VO 2 ) were calculated using HR and speed respectively. Bivariate correlations (non-parametric Spearman's ρ correlation) between EE, VO 2 and acceleration variables were tested.Spearman's ρ correlation was positive between both EE and VO 2 , and maximum acceleration, acceleration amplitude and RMS and negative for minimum acceleration. Acceleration variables of vertical and lateral movement were generally better correlated with EE and VO 2 (p < 0.001) than those of forward movement (p < 0.01).The results of this innovative approach reveal that the determination of EE in horses could be assessed using inertial platforms. Moreover vertical and lateral movements appear to influence more EE than forward movement.
