Non Technical Summary
Fertility is an essential factor controlling livestock production to feed the ever increasing human population. Bull fertility is vital for cattle reproduction because sperm from a single bull can be used to inseminate thousands of cows, thereby creating significant bull effect. There is a lack of fundamental knowledge on sperm biomarkers to evaluate semen quality and predict bull fertility. Lack of such knowledge and technology is a significant problem because it is hindering the advancement of basic reproduction science and biotechnology. Our central hypothesis is that seminal plasma and sperm from bulls with different fertility contain small biological compounds that can be used to indicate and improve fertility. The objective is to identify these compounds (metabolomes) in seminal plasma and sperm from Holstein bulls using GC-MS and then analyze the data to identify patterns and relationships among the metabolomes. We expect to develop reliable fertility markers, which are significant development in reproductive science because such biomarkers will advance basic animal science and reproductive biotechnologies. The outcome of the expected results will have positive impact on cattle reproduction, production, and product quality. Using the innovative fertility makers, animal producers will be able to select the most fertile bulls to increase efficiency of their herd reproduction and decrease the costs associated with housing, feeding, and labor that would have been spent for low fertile bulls and nonpregnant cows. These results enhance reproductive knowledge and biotechnology of other mammals including humans, thereby enhancing the quality of life.

Outputs
Target Audience:Diverse groups of audiences have been targeted and reached. For example, through the conduct of research, graduate students were empowered with technical and soft skills and these students have resented their research to other students and faculty members. Throughpeer-reviewed publications, students, scientists, animal producers, educators, and the public have been reached out. The PI, Dr. Memili was an invited plenary speaker at the international conference of the Association for Applied Animal Andrology (AAAA) scheduled to take place in Bolognia, Italy in the summer of 2020. Although the conference was canceled due to COVID-19, the proceedings including the PI's article was published and made available to the global community through the Journal of Animal Reproduction Science. Some of the research results were also presented at other conferences including the Plant and Animal Genome Conference. Changes/Problems:Initially, we had a significant delay of several months because of the delays in receiving the sperm and seminal plasma samples from our industry partners, Alta Genetics, Inc. When the samples were received, we proceeded with the funded project and generated large amounts of data and results. We have requested a no-cost extension which has helped the research team including the students to have time to continue the research. However, since early 2020, due to COVID-19, our research progress has slowed down and we could not complete the remaining experiments to validate our results. As such, a further extension is needed to complete the validation experiments and analyze the data. What opportunities for training and professional development has the project provided?Quality training programs have been provided to undergraduate, graduate, and postdoctoral students both in technical laboratory settings and in quality mentoring which helped students develop sound soft skills including scientific communication skills. How have the results been disseminated to communities of interest?The results of the research were disseminated through peer-reviewed publications and conference presentations. The list of publications is also provided through the PI's web page at Mississippi State University. What do you plan to do during the next reporting period to accomplish the goals?We plan to validate our research findings to complete the projects in the funded research.

Impacts
What was accomplished under these goals? Peer-reviewed publications: Through the research, we have produced new knowledge and uncovered metabolomic profiles of sperm and seminal plasma from bulls with different fertility phenotypes. Fertility markers: We have determined biomolecular markers in sperm and seminal plasma that can be used to evaluate semen quality and predict bull fertility. Empowered graduate students: Students developed both technical and soft skills. New data and results generated advance both fundamental and applied science with a positive impact on science and society.

Progress 05/01/18 to 04/30/19

Outputs
Target Audience:The diverse audience has been the direct beneficiary of the current project. The audience includes students, researcher and livestock producers from Mississippi, the United States, and the world. The audience includes women and underrepresented minorities. Both the local and national agricultural communities have been informed about the research results through conference presentations and publications. The science-based solutions for enhancing cattle reproduction and production efficiency has paramount importance both for economic reasons for enhancing the quality of life. Changes/Problems:During the course of research thus far, we have encountered a major delay in the attainment of sperm and seminal plasma samples from bulls with reliable different fertility phenotypes. Although securing the samples caused us a delay of more than eight months, we were able to pursue the original research and obtain quality preliminary results some of which have already been published or submitted for publication in high caliber journals. As such, we have requested a no-cost extension which is vital for completions of the project, so that we will be able to fully accomplish the goals. What opportunities for training and professional development has the project provided?Diverse students including two postdoctoral research associates (one female, one male), four graduate students (two females and two males) and a female undergraduate student have developed essential skills in contemporary animal science and in the cutting-edge science of metabolomics. In addition, the students have attained vital soft skills including scientific thinking, experimental design, data analyses and interpretation of results, presentations of scientific results at national and international conferences, and research manuscript and proposal writing. How have the results been disseminated to communities of interest?The early findings on seminal plasma metabolomes were published as an article in the prestigious peer-reviewed scientific journal, PLoS One, and findings on sperm metabolomics in a manuscript have been accepted publication in the peer-reviewed journal BMC Genomics. We have also submitted our findings on lipidome of sperm and amino acids of seminal plasma to Scientific Reports and Frontiers in Cell and Developmental Biology, respectively. What do you plan to do during the next reporting period to accomplish the goals?During the next reporting period, we have specific and attainable research objectives: Confirm the metabolomic markers identified in our preliminary studies in sperm and seminal plasma samples. Ascertain patterns and relationships among the fertility marker metabolomes to develop extenders to increase post-thaw viability of bull sperm.

Impacts
What was accomplished under these goals? The impact is that research has produced potential biomarkers that are powerful fertility markers to evaluate semen quality and predict bull fertility. The issue is that despite thousands of dollars economic impacts, there exists no reliable set of fertility markers to determine semen quality and predict male fertility. Despite producing ample amounts of sperm with normal morphology and motility, some bulls are afflicted with subpar fertility. Current conventional tests are not able to discern the sperm attributes associated with low fertility. There is a gap in the knowledgebase in that molecular mechanisms regulating the low fertility. The objective of this research is to test the hypothesis that sperm and seminal plasma metabolomes are associated with bull fertility using metabolomics and computational biology approaches. Our preliminary findings have revealed the list of differentially expressed metabolites in sperm and seminal plasma of bulls with different field fertility phenotypes.
