Since 1939, scientists have studied estrous cycle manipulation in dogs resulting in more articles published in this field than any other area of canine reproduction. Estrous cycle manipulation in dogs must be safe and reliable. Dopamine agonists, gonadotropin-releasing hormone agonists, and gonadotropins are hormones that have been used for estrus...
As bovine parturition nears, the placentome undergoes changes that allow placental delivery within 12 hours after calving. These changes include the expression of enzymatic proteins (e.g. MMPs) within the placentome that are capable of breaking down collagen, allowing for the separation of the cotyledon from the caruncle. Dysregulation of either...
Background: Even with numerous successful Trap-Neuter-Release programs, feral cat populations continue to grow. Our laboratory is interested in determining if an underlying biological cause exists for the exuberant reproductive success in this once domestic subspecies. An earlier age for developing reproductive capacity (onset of spermatogenesis in males) may be one...
Similar to the mammalian placenta with the chorioallantois and amnion, the avian yolk sac membrane (YSM) is comprised of the area vitellina (AVI) and area vasculosa (AVA), respectively. Understanding incorporation and delivery of nutrients (especially fatty acids) between these membranes and the developing embryo is important for improving hatchability and...
Free-roaming horse (Equus caballus) management is a complex issue incorporating social, economic, emotional, political, and environmental factors. Currently, few proven field techniques exist for managing free-roaming horse population growth, which can reach 20–25% annually. Although there are several strategies available for sterilizing mares when managing free-roaming horse populations, surgical vasectomy...
Cytogenetic chromosome maps offer molecular tools for genome analysis and clinical cytogenetics and are of particular
importance for species with difficult karyotypes, such as camelids (2n = 74). Building on the available human-camel zoo-fluorescence
in situ hybridization (FISH) data, we developed the first cytogenetic map for the alpaca (Lama pacos,...
