Replacing conventional feed ingredients with agro-industrial by-products may reduce the environmental impacts of dairy production systems. Therefore, this study evaluated the carbon footprint and selected environmental impacts related to wa...
Differences in estimates of genomic and conventional inbreeding: Reasons and Implications [0.03%]
基因组近交估算与传统近交估算的差异及其原因和影响
Christine Anglhuber,Eduardo C G Pimentel,Reiner Emmerling et al.
Christine Anglhuber et al.
Genomic inbreeding coefficients, when calculated in a way to reflect the true level of homozygosity of an individual at genomic markers, result in considerably higher inbreeding trends per year at a population level when compared with the p...
Work satisfaction as a component of social sustainability on dairy farms with cow-calf contact or early separation in Austria [0.03%]
奥地利母犊同养或早期分离乳牛场工作满意度作为社会可持续性的一部分
Anna Rademann,Marie L Schneider,Stefan Hörtenhuber et al.
Anna Rademann et al.
Early separation (ES) of cow and calf in dairy farming is a contested topic from an animal welfare point of view. Moreover, farmers often face severe challenges with regards to their work satisfaction and well-being. Both animal welfare and...
Genetic correlation analyses of serum biochemical variables with health, fertility, and production traits in Holstein cows [0.03%]

Serum biochemical variables, including concentrations of positive acute phase proteins, metabolic indicators, protein composition, and liver enzymes, reflect metabolic, immune system and production disruptions. Some of these serum biochemic...
Selective and time-dependent transfer of herb-derived terpenes into cow milk without sensory impacts [0.03%]
选择性且时间依赖性的将牧草衍生的茋转移至牛奶中而不影响感官属性
Attila Kiss,Levente Czeglédi,Tarek Alshaal et al.
Attila Kiss et al.
Herb supplementation is increasingly researched in dairy nutrition, yet the availability of comparative data on the short-term transfer kinetics of herb-derived terpenes into milk and their sensory relevance remains limited. Major objective...
