1全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2
