Increased β-hydroxybutyrate (BHBA) concentration affect follicular growth in cattle

Metabolic stress conditions caused by negative energy balance (NEB) have been associated with reduced fertility in cows. β-hydroxybutyrate (BHBA) is the main circulating ketone body, which accumulates within follicular fluid.

Zusammenfassung:Metabolic stress conditions caused by negative energy balance (NEB) have been associated with reduced fertility in cows. β-hydroxybutyrate (BHBA) is the main circulating ketone body, which accumulates within follicular fluid. The aim of this study was to evaluate the effects of BHBA on follicle growth and on ovulatory mechanisms in cattle. At 72 h after intrafollicular injection, there was a decrease in follicular diameter in BHBA group compared to control (P = 0.02). Furthermore, follicle growth rate was reduced post-treatment with BHBA in comparison to the control group (P
