Abstract

Bovine abortion is a worldwide problem, but despite extensive histopathologic and molecular investigations, the cause of abortion remains unclear in about 70% of cases. Cellular debris is a commonly observed histopathologic finding in the fetal placenta and is often interpreted as necrosis. In this ...

Abstract

Foetal sex determination using polymerase chain reaction (PCR) in mammals is based on the amplification of gender-specific foetal DNA sequences circulating in maternal blood. The bovine synepitheliochorial placenta does not allow a direct contact between the trophoblast and the maternal blood,...

Abstract

The objectives were to evaluate the associations of lying time (LT) during the first 14 d in milk (DIM) with milk yield, cyclicity (CYC), culling within 60 DIM (CULL), and reproductive performance of lactating dairy cows. A total of 1,052 Holstein cattle (401 nulliparous heifers and 651 parous ...

Abstract

Body condition loss during early lactation varies among cows in the herd and is associated with future health and reproductive outcomes. The objective of this study was to gain a greater understanding of the relationship between previous calving interval and body condition change during the first...

Abstract

Combined thickness of the uterus and placenta (CTUP) has been used for many years to assess fetal well-being and placental health in the mare and most recently the combined thickness of the uterus and interplacentome region (CTUIR) in water buffalo. The aim of this study was to develop normal...

Abstract

In the bovine synepitheliochorial placenta, restricted trophoblast invasion requires complex interactions of integrin receptors with proteins of the extracellular matrix (ECM) and integrin receptors of neighboring cells. Activated integrins assemble to focal adhesions and are linked to the actin...

Abstract

Retained placenta is a worldwide recognized clinical condition in puerperal cows, which can significantly affect their health and fertility. Available treatment modalities are often of questionable efficacy or associated with time constraints, practicality or monetary considerations for their wide...

Abstract

The primary objective of this study was to identify herd management and cow characteristics that are associated with abortion in cow-calf herds in Western Canada. Reproductive events were closely monitored in 29,713 cows in 203 herds from the beginning of the breeding season in 2001 through the...

Abstract

The periparturient period is the most critical period in dairy cows regarding health status and production. Changes in the metabolic profiles, associated with the transition from the dry period to calving to early lactation, may increase the production of reactive oxygen species (ROS). The...

Abstract

Peri-gastrulation defines the time frame between blastocyst formation and implantation that also corresponds in cattle to elongation, pregnancy recognition and uterine secretion. Optimally, this developmental window prepares the conceptus for implantation, placenta formation and fetal development....
