Palatability in horses refers to the acceptability of feed and supplements based on flavor, texture, and aroma, influencing feed intake and nutritional management. It is a key factor in ensuring adequate nutrition and maintaining health, as horses may refuse to consume unpalatable feed, leading to nutritional imbalances. Various factors affect palatability, including ingredient composition, processing methods, and individual horse preferences. Research in this area explores the sensory characteristics that influence feed acceptance and the impact of palatability on dietary choices and overall health. This page compiles peer-reviewed research studies and scholarly articles that investigate the factors affecting palatability, methodologies for assessing feed preferences, and the implications for equine diet formulation.
Abbas G, Ghafar A, McConnell E, Beasley A, Bauquier J, Wilkes EJA, El-Hage C, Carrigan P, Cudmore L, Hurley J, Gauci CG, Beveridge I, Ling E....This study quantified the extent of anthelmintic resistance (AR) in ascarid and strongylid nematodes against commonly used anthelmintics in Australian Thoroughbred horses. Faecal egg count reduction tests (FECRTs, n = 86) and egg reappearance period (ERP) tests were conducted on 22 farms across Australia. Faecal egg counts (FECs) were determined using the modified McMaster technique, and percent faecal egg count reduction (%FECR) was calculated using the Bayesian hierarchical model and hybrid Frequentist/Bayesian analysis method. The results were interpreted using old (published in 1992) and...
Springer RW, Mason AC, Cross TD, Guay KA, Raub RH, Wellmann KB, Jones TN.With greater availability of hemp (Cannabis sativa L.) due to recent legislation, hempseed meal (HSM) should be evaluated as a potential feedstuff for livestock. The study objective was to evaluate the palatability of HSM in horses. Trial 1 used a modified 3 × 3 Latin Square design utilizing three geldings and three mares. Feeding periods (6d) consisted of two feedings/d with a washout phase (3d) before each treatment phase (3d). During treatment, horses were offered soybean meal pellets (SBM), rice bran pellets (RBP), or beet pulp pellets (BPP) in one bucket (500 g) and HSM in a second buc...
Warnken T, Schaub C, Delarocque J, Frers F, Feige K, Sonntag J, Reiche DB.Oral glycemic challenge (GC) tests are recommended for diagnosis of insulin dysregulation (ID). Various protocols are used, but all have limitations in terms of palatability, ease of use, variable composition, geographic availability, or some combination of these. Objective: To evaluate newly developed formulations with defined carbohydrate composition for use as oral GCs. Methods: Thirty-four horses and ponies in various metabolic states. Methods: Our objectives were carried out in 2 separate cross-over experiments. First, the palatability and acceptance of various GCs (2 syrups, 1 granulate)...
de Laat MA, Warnken T, Delarocque J, Reiche DB, Grob AJ, Feige K, Carslake HB, Durham AE, Sillence MN, Thane KE, Frank N, Brojer J, Lindase S....A glycemic challenge test is used for the diagnosis of insulin dysregulation (ID) in horses and ponies. Different forms of the test exist where the administrative route and dose of glucose vary, which makes interpretation of results challenging. Objective: To evaluate the palatability of, and blood glucose and insulin responses to, carbohydrate pellets fed as an oral glucose test (OGT), and to establish the diagnostic threshold for ID when using the pellets. Methods: University and privately-owned horses and ponies (n = 157) comprised of 31 breeds and both sexes. Methods: Multicenter cohort ...
Stachurska A, Tkaczyk E, Różańska-Boczula M, Janicka W, Janczarek I.The commercial horse feed industry uses palatants to mask undesirable tastes of feeds and enhance product acceptance. However, an unknown odour or taste may also hinder feed intake, due to, inter alia, novelty. The objective of the study was to assess the horses' response to novel diet: five different herbs added alternately to dry, wet or wet-sweetened oats. Twenty adult horses were given different diet combinations of a feed presentation and a herb: field mint, common yarrow, common chamomile, common sage and common nettle, consecutively, once daily. The response to novelty was assessed rega...
Francis JM, Neander CR, Roeder MJ, Perry EB.Palatants may be added to equine feed and medication either during or after manufacturing to enhance product acceptance. Prior studies have examined a variety of palatants but results have been limited and inconsistent. Therefore, the objective of this research was to evaluate topically applied oil-based palatants on feeding preferences in horses. Stock-type horses (n = 10) were used in this paired preference test across a two-phase study. Phase one compared six palatants (banana, anise, peppermint, apple, spearmint, and orange) to a control (corn oil), whereas phase two compared preference a...
Longhofer SL, Reinemeyer CR, Radecki SV.The efficacy of top-dress antiinflammatory drugs ultimately depends on a patient's willingness to consume treated feed. The current study compares the palatability of two phenylbutazone top-dress formulations (Equipalazone Powder, Dechra Pharmaceuticals, and Pro-Dynam, VetXX, Ltd.) and a suxibuzone top-dress formulation (Danilon Equidos, Janssen Animal Health). Results of a three-period, crossover study on 18 healthy horses showed that Pro-Dynam was significantly less palatable, with significantly less consumption of treated feed compared with either Equipalazone Powder or Danilon Equidos. The...
