The study was carried out on 27 healthy primiparous Holstein heifers (620 ± 50 kg) kept in a commercial dairy herd. The animals were divided into two groups taking into account the body condition score (BCS) index: BCS < 3.5, n = 12; BCS > 3.5 n = 15. The study period started one month before calving (BC), and ran until one month after calving (AC)...

Rumen content is a complex mixture of feed, water, fermentation products, and living organisms such as bacteria, fungi, and protozoa, which vary over time and with different feeds. As it is impossible to reproduce this complex system in the laboratory, surgical fistulation and cannulation of the rumen is a powerful tool for the study (in vivo and i...

Dairy cows undergo a period of insulin resistance (IR) following calving, but the mechanisms causing IR are not fully understood in cattle. In human type II diabetes, there is strong evidence that oxidative stress (OS) plays a causative role in the development of IR, and antioxidant supplementation can be used to reduce its consequences. Transition...

Post-parturient insulin resistance (IR) is a common feature in all mammalian animals. However, in dairy cows, it can be exacerbated because of high milk yield, leading to excessive negative energy balance, which is related with increased disease incidence, reduced milk production and worsened reproductive performance. IR has been extensively invest...

Production diseases are established when there is an intense imbalance between what is offered to the animal (as food) and what is required (in the form of milk/meat/offspring). In such situations, the solution involves not only the assessment of animal ration or the health program, but also, their health status. This information can only be access...

Dairy cows are especially vulnerable to health disorders during the transition period, when they shift from late pregnancy to the onset of lactation. Diseases at this stage affect not only the animals' well-being, but also cause a major economic impact in dairy farms, because apart from treatment costs, affected cows will not reach their peak milk-...

New-born calves depend upon colostrum intake for the acquisition of immunoglobulins (Ig) and other beneficial substances. However, colostrum is also a source of reactive oxygen species (ROS). Intrinsic production of ROS also increases after birth, so the combination of colostral and intrinsic ROS could overwhelm the antioxidant capacity of the calf...
