Association between nutritional values of hays fed to horses and sensory properties as perceived by human sight, touch and smell

International audience; Although hay is the foundation of most equine diets, horse owners rarely ask for biochemical analysis and the routine practice is to choose hay based on its 'perceived' nutritional value. The present study aimed at exploring the relationship between sensory properties as perceived by sight, touch and smell, and the nutritional value of hay measured by biochemical analysis using a 'free sorting task' method. Fifty-four non-expert participants were asked individually to: (1) observe 21 hays samples, (2) group together hays that they perceived as similar for each of the three modalities (hay appearance, odour or texture) and (3) characterize each formed group with a max…

66  In vitro comparison of six raw materials on gastric ecosystem activity and acidity

International audience; The great biochemical variability of the raw materials used in horse feeds can induce changes in gastric fermentation, and therefore affect gastric health through the resulting acidity of the bacterial end products. This in vitro trial compared the effect of 6 raw materials (BA: barley; WB: wheat bran; OA: oats; SM: sunflower meal; SB: sugar beet pulp; AL: alfalfa – Table 1) commonly used in horse feeds on gastric bacterial fermentation and buffering capacity. In 3 horses fed a mixture of the 6 raw materials 3h before sampling, gastric chyme was collected via a nasogastric tube and mixed. Bottles containing 1mL of the mixed gastric chymes, 50mL dilution medium and 1.…

The use of equine K4b2 during incremental field exercise tests in driven Standardbred trotters: a preliminary study

The equine K4b2 system is well tolerated by horses and allows O2 and CO2 measurements in field conditions up to maximal workload. The relationship between maximal oxygen consumption (VO2max) and maximal aerobic speed (MAS) still needs to be established.
