E Sarmikasoglou et al.
Short-stature corn hybrids carrying the brachytic2 (br2) mutation have greater standability and have grain yields similar to conventional tall hybrids; thus, they are promising for grain production. Our objective was to determine if short h...
The effects of saturated fatty acid supplements on plasma and milk concentration of fatty acid esters of hydroxy fatty acids in dairy cows [0.03%]
饱和脂肪酸补充剂对奶牛血浆和乳脂中羟基脂肪酸酯含量的影响
M Arif,B A Harsch,C Matamoros et al.
M Arif et al.
Fatty acid esters of hydroxy fatty acids (FAHFA) are a novel class of bioactive lipids with demonstrated antidiabetic and anti-inflammatory properties in rodent models and humans but have not been investigated in cows. The major FAHFA are s...
Detecting heat stress: Examination of temperature-humidity index thresholds for respiration rate and body temperature in barn- and pasture-housed peripubertal dairy heifers [0.03%]
检测热应激：围产前期乳牛呼吸频率和体温的温度湿热指数阈值的研究——拴系与放养条件下
K M Daniels,M D Ellett,C L M Parsons et al.
K M Daniels et al.
If animals cannot dissipate accumulated heat from metabolism and the environment, heat stress (HS) occurs. Temperature-humidity index (THI) thresholds for peripubertal dairy heifers are not well defined, despite their known susceptibility t...
Raw milk from individual teats with an optimal teat-end score has lower spore levels compared with teats with a suboptimal teat-end score [0.03%]
与乳头末端得分较差的奶牛相比，乳头末端得分为优的单个乳头发奶中孢子水平更低

Udder health in dairy cows is routinely monitored (for example, through determination of SCC) to help identify and control mastitis and other infectious diseases. Another parameter used to both assess udder health and milking machine perfor...
The predominance of Penicillium, Mucor, and Yarrowia among spoilage fungi in cultured dairy products produced by 3 manufacturers, as revealed by amplicon sequencing [0.03%]
基于扩增子测序的3家生产企业发酵乳腐败霉菌中青霉属、犁头霉属及球拟酵母属占优势

Fungal spoilage in cultured dairy products causes consumer dissatisfaction, food waste, and financial losses. This study aimed to identify and characterize fungi responsible for spoilage in cultured dairy products by amplifying the ITS1-5.8...
Relationship between oxygenated fatty acid and milk fat concentration during diet-induced milk fat depression in dairy cows [0.03%]
日粮诱导的奶牛乳脂率下降期间氧合脂肪酸与乳脂浓度之间的关系
Y A Adeniji,C Matamoros,R E Walker et al.
Y A Adeniji et al.
Altered rumen biohydrogenation of UFA is central to the current understanding of diet-induced milk fat depression (MFD) in dairy cows, and associations with numerous trans fatty acids (FA) have been characterized. Although some specific CLA...
The microdrip method rapidly and efficiently enumerates bacterial colony-forming units in bovine milk [0.03%]
微滴法可快速高效地统计牛乳中的菌落形成单元数量
Kristi L Jones,Nicole Adams,Anna M Lundgren et al.
Kristi L Jones et al.
In vivo microbial challenge models are an important tool to study the mechanistic details of bovine mastitis. A critical element of these studies is the enumeration of the bacterial load in milk to determine if interventions induce physiolo...
Evaluating the impact of milk sample-based pregnancy test procedures on milk production and daily time budgets of dairy cows [0.03%]
基于牛奶样本的妊娠试验程序对乳牛产奶量和日常时间预算的影响评估
Sushil Paudyal,Juan M Piñeiro,Artur Grando Pilati et al.
Sushil Paudyal et al.
Prolonged restraint of dairy cows during pregnancy diagnosis in headlocks can elicit stress responses, potentially compromising animal welfare and productivity. Sample-based pregnancy testing (SBPT) utilizing milk samples obtained at the mi...
Application of multivariate techniques for estimating herd feed efficiency using chemical and near-infrared calibration models in dairy cattle [0.03%]
基于化学和近红外校正模型的奶牛群体饲料利用率多变量估算技术的应用研究
Valentina Novara,Mattia Masseroni,Maddalena Canossa et al.
Valentina Novara et al.
Feed efficiency (FE) is an indicator of overall farm nutritional efficiency, helping farmers to identify any critical points in nutritional management. Particularly, FE is a measure of the ability of animals to convert feed into milk and it...
Using saturation rational function models to calculate yield adjustment factors across varied milking frequencies [0.03%]
利用饱和有理函数模型计算不同挤奶频率下的产量调整因子
Xiao-Lin Wu,John Cole,Asha M Miles et al.
Xiao-Lin Wu et al.
Milking frequency significantly affects milk yield in dairy cows, with higher frequency generally leading to greater lactation yields. The increase follows a nonlinear pattern, showing diminishing returns and eventually reaching saturation ...
