Temporal Alterations In Bovine Placental Capacity During Compromised Pregnancies, Zully E. Contreras Aug 2021

Temporal Alterations In Bovine Placental Capacity During Compromised Pregnancies, Zully E. Contreras

Theses and Dissertations

The circadian rhythms are not solely regulated by photoperiod but are also influenced by feed regimen. Therefore, maternal nutrient restriction during gestation could potentially impact the fetal circadian rhythm. Melatonin, a circadian rhythm modulator hormone, has shown to act as an antioxidant reducing reactive oxygen species during stress exposure; and two potential mechanisms have been proposed for melatonin causing vasoconstriction and vasodilation regulating blood flow. In livestock species, nutrient restriction during gestation reduces uterine blood flow, limiting nutrients availability to the fetus for growth and development. Therefore, this project aimed to use beef heifers to evaluate the maternal nutrient restriction …

Effects Of Acute, Chronic, And Cyclical Hypoxia On The Physiology And Transcriptome Of Channel Catfish (Ictalurus Punctatus), Brian Ott Aug 2021

Effects Of Acute, Chronic, And Cyclical Hypoxia On The Physiology And Transcriptome Of Channel Catfish (Ictalurus Punctatus), Brian Ott

Theses and Dissertations

Channel catfish (Ictalurus punctatus) are raised for aquaculture in ponds characterized by dramatic swings in dissolved oxygen concentration. If morning dissolved oxygen concentration falls below approximately 3.0 mg/L catfish consume less feed, leading to a reduction in growth and production. Although the effects of low oxygen on channel catfish appetite have been described, the underlying mechanisms responsible for those effects are unknown. Increased production of the neuropeptides corticotropin-releasing factor (CRF) and urotensin I (UI) are implicated in other fishes as neuropeptides that reduce appetite once an environmental stressor is detected. This project characterizes the hematological responses and transcriptional response of …
