Many changes in feed production and the management and genetics of cattle have occurred over the past 50 years which affect the efficiency, productivity and environmental impacts of beef cattle production. Trends in feed and animal producti...
Dosing frequency, fecal sampling, and digestibility method influence titanium dioxide-based intake estimates in dairy heifers [0.03%]
给药频率、粪便采样和消化率方法影响乳清粉中二氧化钛摄入量估算值
David M Jaramillo,Lisa M Bauman,Matthew S Akins et al.
David M Jaramillo et al.
Indigestible markers continue to be among the best tools available for estimating intake, especially when individual animal feeding cannot be feasibly measured. Titanium dioxide (TiO2) is a commonly used external marker for estimating fecal...
Prevalence and concentrations of major bacterial pathogens in liver abscesses and ruminal and colonic epithelial tissues in relation to abscess severity in feedlot cattle [0.03%]
与肉牛肝脓肿严重程度相关的肝脏、瘤胃和结肠上皮组织中主要细菌病原体的流行率和浓度关系研究
Mina Abbasi,Reese A Wilson,Kasi N Schneid et al.
Mina Abbasi et al.
Liver abscesses (LA) in cattle are commonly categorized as mild or severe, based on the size and number of abscesses, and only the latter has significant economic impact. Fusobacterium necrophorum subsp. necrophorum, F. necrophorum subsp. f...
Ruminal biohydrogenation and microbial lipids in dairy cows supplemented with fractionated palm oil or Hermetia illucens oil [0.03%]
分段棕榈油或赫梅蒂亚虫油补充对奶牛瘤胃生物氢化和微生物脂质的影响
Pablo G Toral,Lara Rastello,Gonzalo Hervás et al.
Pablo G Toral et al.
In dairy production, Hermetia illucens oil (HIO) could represent a more sustainable energy source than oil palm products, but no in vivo information is available on the effects of this strategy on ruminal biohydrogenation and microbial-deri...
Effect of steam-pelleting or extrusion on nutrient digestibility of ground barley or faba bean in growing pigs [0.03%]
蒸汽制粒或挤压对生长猪巴旦木或蚕豆营养消化率的影响
U S Ruiz,G C Luna,L F Wang et al.
U S Ruiz et al.
Plant-based feedstuffs may have limitations in nutrient digestibility and nutritional value for pigs that might be ameliorated using heat processing technologies. Thus, the main objective was to evaluate the effect of steam-pelleting or ext...
Breed-specific enteric methane emission factor assessment in Italian dairy cattle leveraging DHI and primary ration data [0.03%]
利用DHI和基础日粮数据评估意大利乳用牛品种特异性肠道甲烷排放因子

Giulia Ferronato et al.
Enteric methane (CH4) emissions from dairy cattle are a major contributor to greenhouse gas footprint in the livestock sector. This study applied Intergovernmental Panel on Climate Change (IPCC) Tier 2 equations to estimate enteric methane ...
Voluntary intake of dry matter and water of sheep fed low dry matter forages and consequences for nitrogen excretion [0.03%]
低干物质饲料对羊干物质和水分采食量及氮排泄的影响
N K Jayasinghe,M Sa Forte,S L Davison et al.
N K Jayasinghe et al.
Low dry matter (DM) forages (25g/kg BW) were observed in all diet-treatments (DM%: 8.5-16.0%), was above 30g/kg BW in eight of ten diet-treatments (8.5-13.3%), and was lowest in the highest diet-treatment DM%. The association of DM% and DMI...
Effects of dietary calcium, non-phytate phosphorus and electrolyte balance on the serum biochemical parameters and nutrient metabolism of yellow-feathered broilers fed a low-protein diet [0.03%]
低蛋白饲粮下日粮钙、有效磷和电解平衡对黄羽肉鸡血清生化指标及养分代谢的影响
Xiaoran Li,Shunying Li,Xiaofeng Guo et al.
Xiaoran Li et al.
This study was conducted to investigate the effects of calcium (Ca), non-phytate phosphorus (NPP), and electrolyte balance in a low-protein diet on the serum biochemical parameters, tibial Ca and phosphorus (P) deposition, and metabolizabil...
Genetic and Environmental Factors Affecting Pregnancy Loss in Nellore Cattle: Insights from a Large-Scale Brazilian Field Database1 [0.03%]

Eriklis Nogueira,Roberto Augusto de A Torres Junior,Luis Carlos L Ferreira et al.
Eriklis Nogueira et al.
Pregnancy loss (PL) is a major constraint on reproductive efficiency in beef cattle, yet its genetic basis remains poorly understood. This study aimed to estimate genetic parameters for PL and to quantify sire-related variation in Nellore c...
Short Communication: FUT1 genetic polymorphism influences susceptibility to F18 enterotoxigenic Escherichia coli infection in pigs [0.03%]
短通信：FUT1基因多态性影响猪对产毒性大肠杆菌易感性
