进行了一系列4 × 4拉丁方消化率试验，以确定不同类型的马消化含有不同水平的纤维和蛋白质的饮食的能力是否有任何差异。马（纯种马，高地小马，设得兰群岛小马和驴）提供了四个糖蜜饲料之一，这些含有不同比例的苜蓿和燕麦秸秆：1.0：0，0.67：0.33，0.33：0.67，0：1，分别。测定了干物质（DM）、有机物（OM）、总能（GE）、粗蛋白（CP）、酸性洗涤纤维（ADF）和中性洗涤纤维（NDF）的表观消化率。用铬媒染纤维（铜纤维）和钴乙二胺四乙酸测定不同日粮的通过率，结果表明，高纤维日粮各组分的消化率均低于低纤维日粮（DM、OM、GE、CP和ADF均P < 0.001）。驴对纤维的消化率显著高于其它马（P < 0.01）。高纤维饲料的胃肠道转运时间显著低于低纤维饲料（P < 0.001），且驴的食物残渣保留时间比其他马类动物长（P < 0.01）。
A series of 4 X 4 Latin-squaue digestibility trials was carried out to determine whether there were any differences between different types of equid in their ability to digest diets containing different levels of fibre and protein. The equids (Thoroughbreds, Highland ponies, Shetland ponies and donkeys) were offered one of four molassed diets in turn and these contained different proportions of alfalfa and oat straw: 1.0: 0, 0.67:0.33, 0.33:0.67, 0:1, respectively. The apparent digestibility of dry matter (DM), organic matter (OM), gross energy (GE) crude protein (CP), acid-detergent fibre (ADF) and neutral-detergent fibre (NDF) were estimated. The rate of passage of the different diets tons measured using Cr-mordanted fibre (Cu-fibre) and Co-ethylene diamine terra acetic acid.All animals digested the components of the high-fibre diets less well than those of the low-fibre diets (P < 0.001 for DM, OM, GE, CP and ADF). Donkeys digested fibre move effectively than the other equids (P < 0.01 for ADF and NDF). he gastro-intestinal transit rime of the high fibre diets was significantly less than that for the low fibre diets (P < 0.001) and donkeys retained food residues longer than the other equids (P < 0.01).
