Two experiments were carried out with Sudan zebu cattle and desert sheep to study the voluntary intake and digestibility of berseem (Medicago sativa) and Abu 70 (Sorghum vulgare) forages when offered ad lib. alone and with supplements of molasses to the cattle and dura grain to the sheep. In both experiments the intake of berseem was significantly higher than Abu 70. Supplementation increased Abu 70 intake and while molasses significantly increased berseem intake by cattle, dura decreased its intake by sheep. On the basis of metabolic body size sheep showed a higher intake of these forages than cattle. There was no significant difference in DM digestibility between berseem and Abu 70 by cattle. Sheep digested berseem significantly better than Abu 70. Molasses and dura significantly increased the digestibility of Abu 70 by cattle and sheep but had no significant effect on the DM digestibility of berseem.
用苏丹泽布牛和沙漠绵羊进行了两项试验，以研究单独自由采食时以及给牛添加糖蜜、给羊添加硬粒谷物作为补充时，埃及三叶草（紫花苜蓿）和阿布70（高粱）草料的采食量和消化率。在两项试验中，埃及三叶草的采食量均显著高于阿布70。添加补充物提高了阿布70的采食量，虽然糖蜜显著增加了牛对埃及三叶草的采食量，但硬粒谷物却降低了羊对其的采食量。基于代谢体重，羊对这些草料的采食量高于牛。牛对埃及三叶草和阿布70的干物质消化率没有显著差异。羊对埃及三叶草的消化显著优于阿布70。糖蜜和硬粒谷物显著提高了牛和羊对阿布70的消化率，但对埃及三叶草的干物质消化率没有显著影响。
