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

19脱毒麻疯树仁粕替代豆粕对生长育肥猪生长性能及组织病理学参数的影响显示文摘研究旨在探讨不同水平的脱毒麻疯树仁粕(DJKM)替代豆粕(SBM)对生长育肥猪的生长性能、血液免疫指标和组织病理学参数的影响。选取初始体重为20.47±1.44 kg仔猪(杜洛克×长白×约克夏)144头,随机分配到6个饮食处理组,每个处理6个重复,每个重复4头猪,试验周期79 d。6个处理组(D1、D2、D3、D4、D5和D6)分别用DJKM替代0、30%、45%、60%和75%的豆粕蛋白质,且每kg饲料含佛波醇酯(PEs)0、2.75、5.50、8.25、11.00、13.75 mg。在第29天,给予D6组3个重复的猪D1饲料(表示为D6+D1)来检测再投喂试验D6饮食残留效应。从第1~79天,D4、D5和D6组平均日增重、平均日采食量和肉料比均显著低于D1组(P〈0.05)。然而,D6组日粮的负面影响在再投喂D1组饲料的两周后消失。此外,与D1组相比,D5和D6组的猪血清碱性磷酸酶活性较高,但血清丙氨酸转氨酶较低(P〈0.05)。并且,还观察到D3、D4、D5和D6组猪的肝脏病理变化。结果表明,DJKM可以用来取代豆粕蛋白质高达30%,对生长性能、血液免疫指标和组织病理学参数没有负面的影响。Li Y Chen L Lin Y Fang Z F Che L Q Xu S Y Wu D 2015饲料博览2015,0,6:0
