摘要: 【目的】研究荨麻作为粗饲料对反刍动物胃肠动力的影响。【方法】以25%、50%和100%麻叶荨麻干草替代苜蓿干草饲喂新疆细毛羊,在饲喂试验的第 1 d、第 7 d、第 14 d、第 21 d和第 28 d监测其对胃肠动力的影响。【结果】第 7 d 100%荨麻组饲喂后开始反刍时间显著晚于对照组(P<0.05);第21 d 50%荨麻组和100%荨麻组羊只一个食团咀嚼次数分别显著(P<0.05)和极显著(P<0.01)少于对照组;一个反刍过程持续时间各组之间差异不明显(P > 0.05);随着荨麻饲喂天数和添加比例的增加,在饲喂后4 h内不出现反刍羊只数量显著增加;瘤胃蠕动频率在第 28 d 100%荨麻组显著少于对照组(P<0.05);荨麻饲喂天数与饲喂后排便延迟时间在50%荨麻组(R2=0.754 6)和100%荨麻组(R2=0.753 1)具有强相关性。【结论】绵羊采食一定比例荨麻干草,具有减弱胃肠动力的作用。提示荨麻或其提取物有望用于缓解反刍动物胃肠痉挛等消化道疾病。

Abstract: 【Objective】 To investigate the effect of Urtica as roughage on gastrointestinal motility in ruminants. 【Method】 In order to investigate the effect of Urtica as a roughage on the gastrointestinal motility of ruminants, 25%, 50% and 100% Urtica hay were used to replace alfalfa hay to feed Xinjiang fine-wool sheep. The gastrointestinal motility was monitored on day 1, 7, 14, 21 and 28.【Result】The results showed that the ruminating time was significantly later in 100% Urtica group on the 7th day than that in control group (P < 0.05). On the 21st day, chewing time of one chew in 50% Urtica group and 100% Urtica group were significantly less than that in the control group (P < 0.05); the duration of one ruminant process was not different among the groups (P > 0.05); The number of sheep with no rumination within 4 h after feeding increased with the increase of days and the proportion of Urtica feeding; the frequency of rumen peristalsis was significantly lower in 100% Urtica group on the 28th day than that in control group (P < 0.05); the relativity was strong between the delay of defecation and the days of Urtica feeding in 50% Urtica group (R2 = 0.754,6) and 100% Urtica group (R2 = 0.753,1). 【Conclusion】This study showed that a certain proportion of Urtica hay that was fed to sheep had the effect of weakening gastrointestinal motility. It is suggested that Urtica or its extracts may be used to alleviate gastrointestinal diseases such as gastrointestinal spasm in ruminants
