This retrospective observational study examined the relationships between production metrics and financial efficiency on dairy farms operating within a production-limited system in Canada. In such a system, production quotas serve as the pr...
Potential roles of colostrum microbiota in shaping calf gut microbiota and colostrum metabolites [0.03%]
初乳微生物对塑造犊牛肠道微生物群及初乳代谢物的潜在作用

Jalyn Hawkins et al.
Colostrum provides vital nutrients and antibodies that are crucial for calf health and survival. It also contains microbes that may be vertically transmitted to calves and influence early gut microbiota development. These microbes in colost...
Heart rate and heart rate variability of dairy cows with or without local anesthesia [0.03%]
局部麻醉对 dairy cows心率和心率变异性的影响

Heart rate variability analysis provides valuable insights into autonomic nervous system function but remains minimally explored in veterinary anesthesiology, particularly regarding its relationship with low-dose caudal epidural anesthesia ...
Characterization of extracellular vesicles at parturition in dairy cows with late-gestation heat stress [0.03%]
围产期热应激对奶牛外泌 vesicles 的影响研究
L T Casarotto,H N Jones,L Galio et al.
L T Casarotto et al.
Extracellular vesicles (EV) are recognized as important mediators of cell-cell communication, capable of transferring various cargo between cells. Thus, EV are potential biomarkers of health status in heat-stressed cows. We hypothesized tha...

Small family dairy farmers are a type of production system in Mexico characterized by family-owned farms where family members are dedicated to the production of milk and dairy products such as cheese. Artisanal cheeses made by small family ...
From milk to maturity: The potential for lactocrine programming of heifer reproduction [0.03%]
从牛奶到成熟：乳激素编程母牛繁殖的潜力
