“…Previous studies have shown that in horses, short‐term light exercise and endurance training can increase insulin sensitivity. Further research reported a dose‐response effect, where insulin sensitivity was greatest in horses during moderate intensity exercise and was significantly higher during light work than during paddock turnout alone .…”

“…The addition of exercise is recommended for horses and ponies that presently are not lame . However, previous work in equids has yielded conflicting results regarding the benefit of exercise, which could stem from differences in research methodology (eg, diet, exercise regimen, and method of SI assessment) and the characteristics of horses studied (eg, breed, level of adiposity, and degree of insulin dysregulation) . Exercise without dietary modification might be insufficient to improve SI in equids despite inducing weight loss, although exercise could provide other health benefits, including decreased biomarkers of systemic inflammation such as serum amyloid A (SAA) concentration …”

BackgroundThe importance of including exercise with dietary modification for the management of obese equids is not clearly understood.ObjectivesTo evaluate the effect of a practical low‐intensity exercise regimen, in addition to dietary restriction, on indices of insulin sensitivity (SI) and plasma adipokine concentrations in obese equids.AnimalsTwenty‐four obese (body condition score [BCS] ≥ 7/9) horses and ponies.MethodsOver a 12‐week period, animals received either dietary restriction only (DIET) or dietary restriction plus low‐intensity exercise (DIET+EX). All animals were provided with a restricted ration of grass hay at 1.25% body weight (BW) on a dry matter basis, providing 82.5% estimated digestible energy requirements. The DIET+EX group undertook low‐intensity exercise 5 days per week on an automated horse walker. Before and after weight loss, total body fat mass (TBFM) was determined, indices of SI were calculated using minimal model analysis of a frequently sampled IV glucose tolerance test, and adipokines plus inflammatory biomarkers were measured using validated assays.ResultsDecreases in BCS, BW, and TBFM were similar between groups (all P > .05). After weight loss, animals in both groups had decreased basal insulin and leptin concentrations, and increased adiponectin concentrations (all P < .001). Furthermore, animals in the DIET+EX group had significantly improved SI and decreased serum amyloid A concentrations relative to animals in the DIET group (both P = .01).Conclusions and Clinical ImportanceRegular low‐intensity exercise provided additional health benefits compared with dietary restriction alone in this population of obese equids.

“…Otherwise, it is worth mentioning that albeit the high SFTs registered and the mean BCS was greater compared to previous studies (Pratt-Phillips et al, 2010;Turner et al, 2011;Wagner & Tyler, 2011), the overall BF% was lower than in other breeds (Vick et al, 2007;Adams et al, 2009;Ragnarsson & Jansson, 2011). Considering these data, we determined that Andalusians were not as overweight as it could appear if we only use BCS to evaluate the body condition.…”

Development of an index based on ultrasonographic measurements for the objective appraisal of body condition in Andalusian horses

Body condition scoring (BCS) is an indirect measure of the level of subcutaneous fat; however, by measuring the subcutaneous fat thicknesses (SFT), the precision of the degree of fatness assessment is improved. The aims were: 1) to develop an alternative body fat scoring index (BFSI) based on ultrasonographic measurements; 2) to assess the agreement between BCS and the new index applied to Andalusian horses; 3) to adjust the BCS cut-off values (if necessary) for overweight and obesity in this breed. One hundred and sixtysix Andalusian horses were included in this cross sectional study. On each horse, BCS, body fat percentage (BF%) and ultrasonography of SFT at localized deposits were evaluated. According to BFSI five possible body categories were established. Only one horse (0.6%) was classified as emaciated, 9.0% as thin, 74.7% as normal, 11.4% as overweight and 4.2% as obese. Despite higher BCS and SFT values were observed compared to other breeds, most of the horses evaluated presented a normal body condition under the new BFSI. BCS and BFSI were significantly associated (p<0.001), however, the concordance was low (weighted Cohen's kappa coefficient, 0.262 ± 0.071; p=0.004). Using BFSI, obese horses had significantly greater BF% than the rest of categories (p<0.001). BCS showed a good diagnostic accuracy for detection overweight (AUC = 0.759 ± 0.055; p<0.001) and obese (AUC = 0.878 ± 0.050; p=0.001) horses; redefining the cut-off values for overweight and obesity condition as 7.5/9 and 8.5/9 respectively in Andalusian horses.Additional keywords: ultrasonography; subcutaneous fat deposits; objective score; adiposity; obesity; index. Abbreviations used: AUC (area under the curve); BMI (body mass index); BCS (body condition score); BFSI (body fat scoring index); ROC (receiver operating characteristic curve); SFT (subcutaneous fat thickness); SFT-N25% (SFT over the first third of the neck-length); SFT-N50% (SFT over the second third of the neck-length); SFT-N75% (SFT over the last third of the neck-length); SFT-S (SFT behind the shoulder); SFT-Rb (SFT over the ribs); SFT-R (SFT over the rump); SFT-TH (SFT over the tailhead); BF% (body fat percentage).
