Bovine mastitis is a major disease affecting dairy cattle worldwide. The milk collected from cows with different type of inflammation, including mastitis, is characterized by an increased number of so...
Corpus luteal angiogenesis in a high milk production dairy breed differs from that of cattle with lower milk production levels
Holstein Friesian dairy cows dual purpose cows corpus luteum vascularisation capillary angiogenesis
2016/10/14
Globally, high producing, young dairy cows often have health and fertility problems such as ovarian, uterine and placental dysfunction, mastitis and impaired wound healing. These health issues can res...
