Article Synopsis
- Anti-Müllerian hormone (AMH) is linked to ovarian reserve, with maternal and environmental factors influencing its levels during early fetal development in dairy heifers.
- This study aimed to investigate if maternal growth before conception and early gestation affects AMH concentrations in female offspring, with a hypothesis that excessive growth would lead to lower AMH levels.
- Results indicated that increasing maternal growth linked to an initial pregnancy diagnosis correlated with reduced AMH in calves, though this accounted for only a small portion of variability in AMH levels.
Long-day photoperiod is known to positively affect milk production in confinement dairy systems, and it has been hypothesized that pineal melatonin (MT) secretion plays a substantial role in this process. Specialized mammalian photoreceptors that regulate MT secretion are optimally stimulated by short wavelength blue light. We investigated the blue light intensity administered to one eye required to suppress MT secretion in nonlactating dairy cows, and subsequently examined effects on milk production in grazing dairy cows.
