Abstract

Long noncoding RNAs(lncRNAs), a kind of noncoding RNA transcripts with the length more than 200 nucleotides, widely exists in cytoplasm and nuclei of animals, plants and microbes. Studies have shown that lncRNAs can regulate gene expression at chromosomal, transcriptional and post-transcriptional...

Abstract

Confirmation of the pregnancy establishment at the very earliest day post-insemination increases the reproduction efficiency of high yielding dairy cows and farm profitability by allowing rebreeding of the non-pregnant cows. Inaccuracies in the currently available pregnancy detection tools to...

Abstract

Estrus detection and timing of AI remains a challenge in cattle breeding. Prolonging spermatozoa lifespan after AI, making sperm cells available over an extended period, could make timing of AI relative to ovulation less crucial and improve fertility. Immobilization of sperm cells by the patented...

Abstract

Oocyte meiosis is a complex process coordinated by multiple endocrinal and molecular circuits. Recently, N6-methyladenosine (m6A) epigenetic modification on RNA is revealed to be important for meiotic maturation. However, the molecular mechanism of how m6A modification exerts its effect on oocyte...

Abstract

Interferon-tau (IFNT) is the main signal for the maternal recognition of pregnancy in ruminants, and exerts its effects by stimulating the expression of interferon-stimulated genes, including the expression of interferon-stimulated gene15 kDa protein (ISG15). Progesterone (P4) exerts significant...

Abstract

The objective was to determine associations between behavior during head-lock restraint and reproductive performance in dairy heifers. Behavior of 817 Holstein heifers from four farms was evaluated at feeding (Days 0 and 7) while restrained in a self-locking stanchion. All heifers were assigned a...

Abstract

Kisspeptin is the protein product of Kiss1 gene. In contrast to its fundamental role as GnRH Secretagogue and puberty initiation, its functions in extrahypothalmic tissues such as the testes remain unknown. The objective of this study was to investigate the potential local role of kisspeptin in the ...
