Grazing provides multiple benefits for dairy farming, including reduced feeding costs, improved animal welfare, environmental services, and enhanced milk composition. Current certification schemes often require a minimum number of grazing d...
Reproductive performance of grazing dairy cows genetically divergent in genetic merit for feed intake [0.03%]
选育饲料报酬不同的放牧乳牛的繁殖性能
M Williams,D P Berry
M Williams
Feed-related costs represent one of the largest variable costs in dairy herds, and, consequently, many countries now include explicit measures of feed intake or feed efficiency in their dairy total merit indexes. Nevertheless, there is a pa...
Welfare indicators for young dairy heifers managed with virtual fencing in northern Sweden [0.03%]
北瑞典利用虚拟围栏管理乳牛小母牛的福利指标
K Liffen,G Vaccargiu,K Ren et al.
K Liffen et al.
This study investigated the effects of virtual fencing (VF) on welfare indicators (i.e., BW, behavior, and hair cortisol) of young dairy heifers under northern Swedish conditions. Thirty heifers aged 126 to 294 d at the beginning of the exp...

Pasture-based dairy systems offer a sustainable and cost-effective approach to milk production, particularly in temperate regions. This review synthesizes current knowledge on the nutritional profile of pastures and the nutritional manageme...
The behavioral response of dairy cows to different shock energies delivered during virtual fencing training [0.03%]
虚拟围栏训练中不同电能对奶牛行为反应的影响
Megan Verdon

The uptake of virtual fencing (VF) technologies to manage grazing dairy cattle is increasing, but little empirical evidence exists to support acceptable thresholds for the electric shock delivered by these systems. This study quantified the...
Effects of an electrolyte, energy, and osmolyte compound and heat stress on productivity in early-lactation Holstein cows [0.03%]
一种含电解质、能量和渗透压调节剂的化合物以及热应激对产犊早期荷斯坦奶牛生产性能的影响
D Onan-Martinez,C Nelson,F T Saputra et al.
D Onan-Martinez et al.
Heat stress affects milk production and intake of dairy cattle. Strategies to mitigate the effects of heat stress suggest dietary supplements including electrolyte, energy, and osmolyte compounds (such as Bovine BlueLite, TechMix, Stewart, ...
