Early embryonic loss is a significant factor in livestock species' infertility, resulting in an economic deficit. In cattle, the in vivo fertilization rate is ~90%, with an average calving rate of about 55%, indicating an embryonic-fetal mortality rate of roughly 35%. Further, 70-80% of total embryonic loss in cattle occurs during the first three weeks after insemination, particularly between days 7-16. Growing evidence indicates that the oocyte plays an active role in regulating critical aspects of the reproductive process required for successful fertilization, embryo development, and pregnancy. However, defining oocyte quality remains enigmatic. Recently, many have abandoned the notion that …

Efficient feed utilization is critical for both economic sustainability and environmental responsibility in modern livestock production. While there has been extensive research, the multifaceted nature of feed efficiency remains complex, with many biological factors still unexplored. This dissertation examines the physiological foundations of feed efficiency by elucidating some of the complex biological mechanisms associated with residual feed intake (RFI) phenotype in beef cattle, using a range of Omics approaches. We hypothesized that metabolites related to amino acids, carbohydrates, and fatty acids could act as potential biomarkers for RFI. Through a chemical group-based metabolomics method, we identified enriched pathways in feed-efficient …
