Evaluation Of Performance Characteristics And Groundwater Contamination Risks Associated With On-Farm Swine Carcass Disposal Via Composting And Shallow Burial With Carbon, Gustavo Castro Garcia
Evaluation Of Performance Characteristics And Groundwater Contamination Risks Associated With On-Farm Swine Carcass Disposal Via Composting And Shallow Burial With Carbon, Gustavo Castro Garcia
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
This dissertation evaluates the performance of three on-farm swine carcass disposal methods: whole carcass composting (WCC), ground carcass composting (GCC), and shallow burial with carbon (SBC), focusing on biosecurity factors and groundwater contamination risks. Foreign animal diseases (FADs), such as African swine fever and classical swine fever, pose severe economic and animal well-being risks if introduced to the United States. With confirmation of an FAD, swine movement will be halted, creating an urgent need for practical, biosecure, and environmentally responsible on-farm disposal strategies for swine carcasses. Nebraska, as a leading swine-producing state, exemplifies the vulnerability of high-density livestock regions to …
Gonadotropin-Releasing Hormone Ii And Its Receptor: Novel Regulators Of Semen Quality And Follicular Function In Swine, Caitlin Elizabeth Ross

Pigs are the only mammalian livestock species encoding functional proteins for the second form of gonadotropin-releasing hormone (GnRH-II) and its receptor (GnRHR-II). In the first study, GnRHR-II localized to developing germ cells and the connecting piece of ejaculated spermatozoa. Concurrently, GnRH-II was most abundantly produced in the testis compared with other reproductive tract organs and was present within seminal plasma. Moreover, treatment of extended semen with GnRHR-II analogues altered sperm motility, morphology, and kinematics. For remaining studies, we utilized a swine line with ubiquitous knockdown of GnRHR-II (GnRHR-II KD) developed in our laboratory. The second study demonstrated that circulating GnRH-II …
Development Of A Durable And Low-Dose Universal Vaccine Against Swine Influenza A Virus, Erika Petro-Turnquist
Development Of A Durable And Low-Dose Universal Vaccine Against Swine Influenza A Virus, Erika Petro-Turnquist
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Swine Influenza A Virus (IAV-S) imposes a significant burden on the pork industry and poses a great threat to public health due to its zoonotic potential. Susceptibility to human, avian, and swine influenza make pigs the ultimate mixing vessels for reassorted influenza A virus strains. Current vaccination strategies induce short-lived and strain-specific responses against IAV-S. Further, the substantial genetic diversity of IAV-S necessitates consistent revaccination and updating of commercial vaccines. Computational platforms have recently emerged as a promising strategy to develop new-age vaccines against infectious diseases in livestock animals. Here, we describe a computationally derived set of vaccine immunogens, called …
