Progesterone plays an important role in the maintenance of pregnancy. It is hypothesised that insufficient progesterone early in pregnancy may result in embryonic loss, and that supplemental progesterone would decrease pregnancy loss in dairy cows. T

The developmental origins of health and disease concept stipulates that nutritional imbalance in the preconceptional and gestational periods induces risks for the development and long-term health of the individual. In industrialized countries, most w

This study introduces a combination of mass spectrometry-based analytical approaches with little or no sample preparation for the study of zebrafish (Danio rerio) lipid metabolism during early development (0 through 96 h post-fertilization, hpf). Des

The canine reproductive physiology is distinct from other mammals, especially concerning the role of progesterone in ovulation, oocyte maturation, and fertilisation. In vitro maturation of canine oocytes is challenging mostly due to the culture condi

We describe an original perfusion system for the culture of whole ovine ovaries for up to 4 days. A total of 33 ovaries were divided into six groups: control (n = 6), not perfused and fixed; Groups SM72 and SM72-FSH (n = 6 each), perfused with a simp

We have shown that inclusion of initial gonadotropin-releasing hormone (GnRH) in a 5-day Co-synch protocol is unnecessary to achieve acceptable pregnancy rates in dairy heifers (2011 Theriogenology 76, 578). This study determined the efficacy of a mo

An oestradiol-based protocol (named J-Synch) has been developed recently with the aim of providing for a longer proestrus, enhancing the development of the dominant follicle before ovulation, and increasing pregnancy rates following fixed-time AI (FT

E. coli is one of the most frequent bacteria involved in uterine diseases. Lipopolysaccharide (LPS) is a component of the outer membrane of Gram-negative bacteria involved in the pathogenic processes leading to postpartum metritis and endometritis in

Several studies, performed mainly in North America, have shown that the 5-day co-synch timed-AI (TAI) protocol results in similar or higher pregnancy rates than conventional 7-day co-synch protocols in beef cows and beef and dairy heifers. It is hypo

The overall objective was to determine the effects of addition of lipid metabolic regulators during embryo culture on blastocyst development and survival following cryopreservation. For Experiment 1, embryos produced in vitro were cultured in 5% (vol
