| 1 | Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers显示文摘Background:Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients.However,little is known about the association between the rumen microbiota and feed efficiency traits in Nellore(Bos indicus)cattle,a breed of major economic importance to the global beef market.Here,we compare the composition of the bacterial,archaeal and fungal communities in the rumen of Nellore steers with high and low feed efficiency(FE)phenotypes,as measured by residual feed intake(RFI).Results:The Firmicutes to Bacteroidetes ratio was significantly higher(P<0.05)in positive-RFI steers(p-RFI,low feed efficiency)than in negative-RFI(n-RFI,high feed efficiency)steers.The differences in bacterial composition from steers with high and low FE were mainly associated with members of the families Lachnospiraceae,Ruminococcaceae and Christensenellaceae,as well as the genus Prevotella.Archaeal community richness was lower(P<0.05)in p-RFI than in n-RFI steers and the genus Methanobrevibacter was either increased or exclusive of p-RFI steers.The fungal genus Buwchfawromyces was more abundant in the rumen solid fraction of n-RFI steers(P<0.05)and a highly abundant OTU belonging to the genus Piromyces was also increased in the rumen microbiota of highefficiency steers.However,analysis of rumen fermentation variables and functional predictions indicated similar metabolic outputs for the microbiota of distinct FE groups.Conclusions:Our results demonstrate that differences in the ruminal microbiota of high and low FE Nellore steers comprise specific taxa from the bacterial,archaeal and fungal communities.Biomarker OTUs belonging to the genus Piromyces were identified in animals showing high feed efficiency,whereas among archaea,Methanobrevibacter was associated with steers classified as p-RFI.The identification of specific RFI-associated microorganisms in Nellore steers could guide further studies targeting the isolation and functional characterization of rumen microbes potentially important for the energy-harvesting efficiency of ruminants. | Déborah Romaskevis Gomes Lopes Márcio de Souza Duarte Alex J.La Reau Ibrahim Zuniga Chaves Tiago Antônio de Oliveira Mendes Edenio Detmann Cláudia Braga Pereira Bento Maria Eugênia Zerlotti Mercadante Sarah Figueiredo Martins Bonilha Garret Suen Hilário Cuquetto Mantovani | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 3 |

| 14 | 黄粉虫替代蛋白质饲料对太平洋白虾(凡纳滨对虾)消化性能的影响显示文摘试验旨在评估黄粉虫粉(MM)作为凡纳滨对虾养殖中蛋白质来源的可行性。饲料分为正常饲料和试验饲粮,试验饲料中包含正常饲料85%和MM 15%,两种饲料中均含有氧化铬0.5%作为惰性标记,试验采用表观消化率系数(ADC)对两种饲料进行检测。为评估MM消化价值,对虾饲料中采用鱼粉替代MM,替代比例分别为0%、25%、50%、75%和100%,在清水中饲养6周后,对生长参数和整个虾体成分进行评估。干物质ADC为45.9%,能量ADC为66.5%,粗蛋白质ADC为76.1%,必须氨基酸ADC为72%~86%。MM中蛋氨酸为第一限制性氨基酸。饲料中添加MM后,各组间对虾的体增重、特定生长率、采食量、饲料转化率、存活率和蛋白质合成率均无显著变化(P>0.05),虾体蛋白质含量无显著差异(P>0.05)。而随着鱼粉替代比例上升,虾体脂含量从1.13%升至1.88%。结果表明,黄粉虫粉可作为凡纳滨对虾饲料中的替代蛋白质饲料,但添加时应注意补充蛋氨酸。 | Panini R L Freitas L E L Guimarǎes A M Rios C da Silva M F O Vieira F N Fracalossi D M Samuels R I | 2017 | 饲料博览2017，0，7： | 1 |
