This study investigates the impact of urea molasses-treated wheat straw on growth performance and nutrient digestibility in Azikheli buffalo male calves. A longitudinal experiment was conducted on sixteen calves, randomly assigned to four experimental dietary treatments (n = 4 per group). The experimental diets included a control group (U0) with untreated wheat straw and three groups where urea molasses-treated wheat straw replaced 33% (U33), 66% (U66), or 100% (U100) of the straw in the total mixed ration. Results indicated that increasing the proportion of urea-treated wheat straw from 0 to 100% led to significant improvements in dry matter intake (from 2931 to 4034 g/day) and organic matter intake (from 2596 to 3623 g/day). Digestibility of dry matter, organic matter, crude protein, and crude fiber also followed an increasing trend, reaching 77.42%, 81.21%, 87.10%, and 60.22%, respectively, at the highest urea-treated wheat straw level. Furthermore, weight gain was significantly greater in calves fed 100% urea-treated wheat straw, followed by those in the U66, U33, and U0 groups. Feed conversion efficiency improved substantially in the U100 and U66 groups than U33 and U0. These findings suggest that incorporating higher levels of UMTWS in total mixed rations enhances nutrient digestibility, promoting superior growth performance and feed efficiency in Azikheli buffalo calves.
本研究调查了尿素糖蜜处理的小麦秸秆对阿齐赫利雄性水牛犊牛生长性能和养分消化率的影响。对16头犊牛进行了一项纵向实验，将其随机分配到四种实验日粮处理组（每组n = 4）。实验日粮包括一个使用未处理小麦秸秆的对照组（U0）和三个组，在这三个组中，尿素糖蜜处理的小麦秸秆在全混合日粮中分别替代了33%（U33）、66%（U66）或100%（U100）的秸秆。结果表明，将尿素处理小麦秸秆的比例从0增加到100%可显著提高干物质摄入量（从2931克/天增加到4034克/天）和有机物质摄入量（从2596克/天增加到3623克/天）。干物质、有机物质、粗蛋白和粗纤维的消化率也呈上升趋势，在最高尿素处理小麦秸秆水平下分别达到77.42%、81.21%、87.10%和60.22%。此外，饲喂100%尿素处理小麦秸秆的犊牛体重增加显著更大，其次是U66、U33和U0组。U100和U66组的饲料转化效率比U33和U0组有显著提高。这些发现表明，在全混合日粮中加入更高水平的尿素糖蜜处理小麦秸秆可提高养分消化率，促进阿齐赫利水牛犊牛的生长性能和饲料效率。
