Activities
Objective 1
- We are working on the refinement of tissue cryopreservation and culture techniques that will improve the prospects of using this as a tool for fertility preservation and efficiently tap into the abundant ovarian reserve of immature oocytes, improving the efficiency of assisted reproduction in cattle. California
- We found evidence of the presence of neurotransmitters and their synthesis and metabolism in the bovine conceptus, which could have greater implications in establishing postnatal offspring behavior. Colorado
- We learned that bulls differentially capacitate and release zinc ions in response to the concentration of bicarbonate present. This is important for the development of translational reproductive biotechnologies to analyze sire fertility potential using economical methods. Iowa
- We showed that the zinc ion localization patterns exist in additional ruminants – goats. This could further our understanding of goat fertility. Iowa
- We characterized a mechanism to identify potentially differentially expressed genes between low- and high-quality bovine oocytes. Utah
- We established that cumulus cells of the ovarian follicle generate non-erythroid hemoglobin that is transported into the oocyte through transzonal projections. This non-erythroid hemoglobin seems to have at least an antioxidant role that may protect the oocyte and subsequent early embryo should fertilization occur from genotoxic stress. Wyoming
- PRAMEY may be used as a biomarker for sperm quality and sperm function. Pennsylvania
Objective 2
- Understanding the roles that FSH may play in the development of preantral follicles is of critical importance as many ovarian stimulation protocols used in assisted reproduction use the hormone to promote antral follicle growth. California
- We partially confirmed our hypothesis of an association of cytological endometritis and DMI and lactation performance. Additionally, cytological endometritis at both 15 DIM and at 30 DIM was associated with days to first ovulation, and further studies should now investigate this association with subsequent reproductive outcomes (i.e., pregnancy), taking into consideration the cows’ intake. Illinois
- Identification of metabolic pathways disrupted in the d14 conceptus were identified in beef heifers exposed to a reduced plane of nutrition. These pathways may be used for targeted supplementation protocols in heifers during the post-AI feedlot to range transition to improve pregnancy retention. Montana
- The open cow test is promising. Testing will continue in clinical trials while improvements in both the level of detection and method of sample collection will continue. Colorado
- We learned that IL-1β could have potential as a therapeutic treatment for enhancing uterine receptivity and improving preimplantation embryo development and survival. Wyoming
- We could determine that post-natal growth and development of calves can be programmed by exposure to choline during the preimplantation period. Wyoming
- Understanding the neural mechanisms for the generation of the preovulatory GnRH/LH surge may enable future technologies to improve fertility and may provide insight to how fertility is suppressed during stress. Colorado
- Understanding cells that make up CL will allow for the development of organoid structures that can be used in vitro to understand signal transduction and metabolic mechanisms critical for luteal function. Nebraska
- Identifying sheep that also have High A4 populations indicates that this phenomena of naturally occurring androgen excess mammalians may be more wide-spread and that they all can be utilized as models for women who have been diagnosed with Polycystic ovary syndrome (PCOS). Nebraska
- Understanding how the elimination of VEGFA may affect other hormones (AMH) and follicular development and reserve are critical to elucidating VEGFA’s function in the granulosa cells. Nebraska
Objective 3
- Identification of genetic markers associated with fertility, in addition to efforts to improve our understanding of the regulation of maternal recognition of pregnancy and embryo survival. Colorado
- Improving our understanding of how BVDV programs the fetal immune system and impacts postnatal responses to secondary infections may help in identifying pregnancies and post-natal calves at risk as well as developing therapeutic approaches to control the infection. Colorado
- We showed that paternal factors at estrus, such as treating embryo recipient cows with pooled seminal plasma, decreased embryo size, increased uterine artery resistance index, and decreased birth weights. Mississippi
- Comparative animal models, such as cow and sheep, provide additional insight into the importance of glucose, fructose, minerals, and amino acids on the development of the conceptus and how dietary supplementation may enhance reproductive performance and successful outcomes of pregnancy and neonatal survival. Texas
- Increased understanding of interferon tau-induced cell signaling may provide greater insight into pregnancy recognition signaling, as well as effects of interferon tau and progesterone/progestamedins to enhance transport of nutrients into the uterine lumen that are essential for establishment and maintenance of pregnancy. Texas
- Increased understanding of prostaglandin function in the developing pregnancy. Texas
- Increased understanding of the maternal vs paternal genome contributions to pregnancy and pregnancy loss. Texas
- We characterized the various methods currently used for dealing with high missingness and zero inflation in single-cell RNA-seq data. Utah
- Suppressing CXCL12-mediated signaling during implantation induces enduring placental effects manifesting later in gestation, highlighting the importance of this chemokine axis during implantation and placentation. New Mexico
- Determined phenotypes to identify sires with potential fertility problems and developed a system to screen and identify sires of high and low fertility before they are released to the field which could improve overall herd fertility and profitability. Wisconsin
- We are working on improving embryo development in vitro through cell culture modifications. The addition of FLI has been shown to improve embryonic development, cryotolerance, and pregnancy rates. By improving the IVP system, we can improve technology adoption by end users. Wisconsin
- We have validated a candidate mutation responsible for the Holstein Fertility Haplotype“HH2”. This provides us with insights into gene function and embryo development. Moreover, by knowing the exact mutation we can phase it out of the population by selective breeding. Wisconsin
- Identified methods/approaches to mitigate pregnancy complications associated with LOS and enhance producer profitability. Missouri
Impacts
- Cows with increased ovarian androgens are sub-fertile with a reduced lifetime reproductive capacity. High androgen cows cost producers money because of delayed puberty, reduced fertility, and early culling from the herd. UN-L is identifying genes associated with greater reproductive longevity. This work is necessary for the development of technologies that will assist in the selection of females with greater lifetime reproductive capacity.
- Understanding the development of the oocyte is restricted by available in vitro technologies. Organoid structures are developed from ovarian dissociated cells and used in in vitro systems to study developing oocytes. MO and UN-L are perfecting these organoid structures so that the development of the oocyte can be studied in detail. These studies will lead to developing and selecting higher quality oocytes, thereby improving assisted reproductive technologies.
- In the uterus, sperm further develop so they are capable of fertilization. Failure of this development results in reduced pregnancy rates. IA and MO have determined that release of zinc ions is necessary for this process and can be used to evaluate sperm quality. The use of higher quality sperm in assisted reproductive technologies will increase fertilization rates, embryo development, and establishment of pregnancy.
- In ruminant livestock animals such as cattle and sheep, infertility due to gamete quality and anovulation poses an economic strain on the producer. Research from this multistate group (TX, CO, NM) has worked to identifies how stressors such as obesity, immune responses, and bacteria within the vagina disrupt proper ovulation and fertilization mechanisms that ultimately result in reproductive failure or the inability to establish a pregnancy in ruminants.
- The sooner livestock can attain sexual maturity the sooner they can produce offspring for economic benefit, and the more likely they have increased longevity to stay in the herd. A selection system based on red blood cell parameters may identify delayed puberty in heifers (NE). Once puberty is attained, ovulation results in an egg, which is varied in its ability to be fertilized. The administration of a hormone that promotes follicle production has promise to improve successful fertilization. In addition, new methods for cryopreservation of unfertilized cow eggs, will have application to improve in vitro fertilization. (CA). These basic biological mechanisms are important to improve systems of estrous synchronization and artificial insemination in beef cattle (KS, ID).
- Ovulation in mammals is caused by hormones released from the brain and pituitary gland. Adequate and timely release of these hormones is essential for female fertility and disruption of hormone release can lead to infertility. CO is discovering the mechanisms that regulate hormone release to induce ovulation. A suite of upregulated genes has been identified in the pituitary gland that may facilitate hormone release and activate neurons during ovulation. These studies contribute to our basic understanding of hormone release for ovulation, which may yield new strategies to improve overall fertility in ruminants.
- In cattle alone, early pregnancy loss costs producers about $1.6 billion in the USA and $1.28 trillion worldwide annually. To mitigate this problem, the USDA-NIFA W4112 project (CO, FL, UT, MS, MT, TX, WY, WI, and SD) has collaborated to study the mechanisms associated with early embryonic development and survival. These studies have resulted in the identification of markers for improved embryo development, maternal factors that support embryo survival, and management techniques and tools to reduce pregnancy loss.
- Establishment of pregnancy, development of the placenta, and placental function are being studied in normal and compromised pregnancies (AZ, CO, WY, TX). Many of the stressors in compromised ruminant pregnancies also occur in human pregnancies (hypoxia. placental insufficiency, metabolic syndrome, intrauterine growth restriction, uterine-fetal infections).The focus of the research is to better understand the normal physiological processes of pregnancy, and how alterations result in suboptimal outcomes, ultimately impacting postnatal well-being and production efficiency.
- Gene expression technologies are used to discover gene expression profiles associated with successful embryo development. Data from these technologies require careful statistical attention to ensure justifiable biological conclusions. UT identified, developed, and applied statistical methods to advance the discovery of important reproductive characteristics, including markers for embryo quality.
- Complications with fetal development limit offspring production potential, which generates monetary losses in the ruminant livestock industry. NM, MS, MO, and CO study placental adaptations and their impact on fetal growth dynamics using cattle and sheep models. By studying fetal overgrowth during pregnancy, fetal infections leading to impaired postnatal feedlot performance and carcass yield, and maternal endogenous, environmental, and seasonal stressors on the placenta and fetal development, therapeutic methods/approaches may be developed to mitigate pregnancy complications and enhance producer profitability.
- Nearly one-half of all pre-weaning lamb deaths occur on the day of birth with low birth weight being the single greatest contributor to lamb mortality. TX is working on elucidating mechanisms of placental development to improve placental function and reduce lamb mortality in order to improve the efficiency of ruminant livestock production systems.
