“…Therefore, recommendations per age and activity level are typically suggested (Coenen, 2013;Jarvis et al, 2019;NRC, 2007). When a hay-only diet was provided to adult and aged horses, macro-and micronutrient digestibility was decreased compared with hay plus complementary feed (Elzinga et al, 2017),…”

“…Therefore, recommendations per age and activity level are typically suggested (Coenen, 2013; Jarvis et al., 2019; NRC, 2007). When a hay‐only diet was provided to adult and aged horses, macro‐ and micronutrient digestibility was decreased compared with hay plus complementary feed (Elzinga et al., 2017), highlighting that horses on a forage‐only diet may benefit from vitamin supplementation. Inadequate mineral provision has recently been reported as a typical finding in PPID cases (Kienzle & Bockhorni, 2018), which reiterates the importance of considering dietary evaluation and mineral supplementation.…”

Summary Pituitary pars intermedia dysfunction (PPID) is a common endocrine disorder affecting equids. To help achieve and maintain healthy body condition, whilst reducing the risk of dietary associated laminitis, appropriate nutritional management is key. This review proposes a stepwise approach to building an individual nutritional plan for equines with PPID. Starting with considerations relating to current and desired body condition and muscle mass, it highlights the importance of providing appropriate amounts and forms of energy, carbohydrate and protein, with further practical considerations regarding the feeding of animals that are often aged and may have particular clinical sequelae to PPID. The next important step is to determine the degree of insulin dysregulation (ID), as this is a major factor associated with an increased risk of laminitis. Animals with ID should be fed low non‐structural carbohydrate (NSC) providing feeds/feedstuffs as well as fresh or preserved forage with NSC content <10‐12% on a DM basis. Finally, adjustments need to be made according to life stage and activity level.

“…Likewise, Ott and Kivipelto () fed weanling horses concentrate‐to‐hay ratios of 64:36 and 50:50 and did not see any differences in growth parameters. That being said, at least in mature horses, a complete hay diet has been shown to be lower in macro‐ and micronutrient digestibility and there is increased risk of a high‐forage diet not meeting micronutrient requirements without additional supplementation (Elzinga et al, ). The same concerns exist if the concentrate portion of the diet is from unfortified grains such as pure oats.…”

The objective of this study was to compare the feed intake and the apparent digestibilities of three different diets varying in concentrate‐to‐roughage ratios in weanling horses (n = 24) at 5 and 8 months of age. Horses were stratified by breed, gender, birth date and body weight and assigned to one of three dietary treatments containing the following concentrate‐to‐roughage ratios on an as‐fed basis: 70:30 (High Con), 50:50 (Equal) and 30:70 (Low Con). All horses were fed their respective diets for a 10‐day adaptation period and a 4‐day collection period at 5 and 8 months. There were no differences in BW or daily feed intake among treatments during both trials. The horses consuming Low Con had a greater amount of faecal output than High Con at both 5 and 8 months (p < 0.01). At 5 months, High Con had the highest crude protein (CP) digestibility (p < 0.05). At 8 months, High Con had a higher CP digestibility than Low Con (p < 0.01) and tended to be higher than Equal (p = 0.07). Acid detergent fibre (ADF) digestibility did not differ among treatments; however, horses fed the Low Con tended to digest a higher percentage of neutral detergent fibre (NDF) than both the Equal and High Con treatments (p = 0.09). Horses in the High Con treatment tended to digest a higher percentage of energy than those in the Low Con treatment (p = 0.06). Weanlings seem to digest protein more thoroughly when fed high‐concentrate diets and may digest fibre more efficiently when fed diets higher in fibre.
