The causes of low fertility in dairy cattle are complex and multifactorial and may be due to
compromised follicle development affecting oocyte quality, a suboptimal reproductive tract …

Early embryo development, implantation and pregnancy involve a complex dialogue
between the embryo and mother. In cattle this dialogue starts as early as days 3–4 when the …

ABSTRACTS Genome-wide association studies are a powerful tool to identify genomic
regions and variants associated with phenotypes. However, only limited mutual confirmation …

Early pregnancy loss markedly impacts reproductive efficiency in cattle. The objectives were
to model a biologically relevant gene signature predicting embryonic competence for …

Secretions of the endometrium are vital for peri-implantation growth and development of the
sheep conceptus. Extracellular vesicles (EVs) are present in the uterine lumen, emanate …

The objective was to characterize endometrial transcriptome on d 17 of gestation in dairy
cows according to conceptus length. Nonlactating Holstein cows (n= 48) were slaughtered …

In ruminants, the establishment of proper conceptus–endometrial communication is
essential for conceptus implantation and subsequent successful placentation. Accumulated …

Despite passing routine laboratory tests of semen quality, bulls used in artificial insemination
(AI) exhibit a significant range in field fertility. The objective of this study was to determine …

The mammalian zygote, formed after a sperm fertilizes an egg, undergoes several rounds of
mitosis and morphogenesis to form the blastocyst. During the peri-implantation period, the …

Reproductive efficiency in livestock is a major driver of sustainable food production. The
poorly understood process of ruminant conceptus elongation (a) prerequisites maternal …
