反刍动物营养NO.0620231饲料研究FEEDRESEARCH日粮添加黑沙蒿对绒山羊肉品质的影响闫俊峰包斯琴高娃赵艳丽郭晓宇郭咏梅闫素梅*（内蒙古农业大学动物科学学院，内蒙古呼和浩特010018）摘要：试验旨在研究黑沙蒿对绒山羊肉品质的影响。选取年龄相近（4月龄）、体重相似、体况健康的去势公羊40只，随机分为2组，每组20个重复，每个重复1只羊。对照组（CON组）绒山羊饲喂精粗比为50∶50的基础日粮，试验组（AOM组）绒山羊饲喂3%的黑沙蒿替代等比例粗料的基础日粮，试验期90d。结果显示，AOM组与CON组山羊的肌肉理化特性无显著差异（P>0.05）；与CON组相比，AOM组绒山羊粗蛋白含量显著提高（P<0.05），粗脂肪含量显著下降（P<0.05）；肾脂、皮下脂肪、背最长肌的胆固醇含量显著降低（P<0.05），大网膜脂的胆固醇含量有降低的趋势（P>0.05）。研究表明，在日粮中添加3%的黑沙蒿可以使绒山羊背最长肌粗蛋白含量上升、粗脂肪含量下降，降低了背最长肌和脂肪组织的胆固醇含量，有利于改善羊肉的营养品质。关键词：绒山羊；黑沙蒿；肉品质；营养成分；胆固醇中图分类号：S827文献标识码：A文章编号：1002-2813（2023）06-0001-04Doi：10.13557/j.cnki.issn1002-2813.2023.06.001EffectofdietarysupplementationofArtemisiaannuaonmeatqualityofcashmeregoatsYANJun-fengBAOSi-qin-gao-waZHAOYan-liGUOXiao-yuGUOYong-meiYANSu-meiAbstract:ThepurposeoftheexperimentwastostudytheeffectofArtemisiaannuaonmeatqualityofcashmeregoat.Fortycastratedramswithsimilarage(4monthsold),weightandhealthwererandomlydividedintotwogroups,with20replicatesineachgroupandonegoatineachreplicate.Thecontrolgroup(CONgroup)cashmeregoatswerefedwithabasicdietwithconcentratetoforageratioof50∶50,andtestgroup(AOMgroup)cashmeregoatswerefedwithabasicdietwith3%Artemisiaannuainsteadofthesameproportionofcoarsediet.Thetestperiodwas90d.TheresultsshowedthattherewasnosignificantdifferenceinthephysicalandchemicalpropertiesofmusclebetweenAOMgroupandCONgroup(P>0.05).ComparedwithCONgroup,thecontentofcrudeproteininAOMgroupwassignificantlyincreased(P<0.05),whilethecontentofcrudefatwassignificantlydecreased(P<0.05).Thecontentofcholesterolinkidneyfat,subcutaneousfatandlongissimusdorsimuscledecreasedsignificantly(P<0.05),whilethec...
