Brief Summary of Minutes

The NCERA-57 group was welcomed by Dr. Duane Davis (local organizer), Dr. Ernie Minton, Associate Director Of Research, College of Agriculture, and Dr. Ken Odde, Department Head of Animal Sciences and Industry of Kansas State University. Dr. Ken Odde also provided relevant statistics for the department, having approximately 1,250 students with 100 graduate students taught by 50 tenure and 5-6 non-tenure tract faculty members.


NCERA57 previous conducted symposia on: Seasonal Infertility, in 2002 (NE); Boar Stud Management and A.I., in 2004 (IA); Reproductive Inefficiency of Small Litter Sizes, in 2006 (NC); Sow Longevity, in 2008 (IN); Gilt Development, in 2010 (IL); Artificial Insemination Technology, in 2012 (IA); Increased Litter Size and Environmental Effects on Pig Quality, in 2014 (NE).


Topics for the next symposium in 2016 were discussed. The following proposition is “temporarily” kept for final decision in mid Fall 2015: Interaction of health and Reproduction. This title is intended to include various issues such as gilt isolation, Hepa filters, impact of gilt/sow longevity, biosecurity, boar fertility, disease transmission through semen, etc.
Timeline:
- By September-October, 2015: Propositions for issues of potential interest should be received,
- By November, 2015: Propositions for Invited Speakers should be received,
- By January-February 2016: Advertisement of the symposium should be ready to be sent out,
Each NCERA-57 member is encouraged to (or should) contribute to aforementioned activities and contact any potential participants such as stakeholders, swine professionals, etc.
- Follow-up is expected by March-April 2016.


Drs. Tim Safranski, Jason Ross, Kara Stewart, and Bret White agreed to organize the 2016 symposium in Columbia, MO. The symposium should be before Memorial Day and before or after the 2016 annual meeting of NCERA-57. The NCERA57 committee decided to charge a registration fee to cover expenses for the symposium.


Deb Hamernik (Administrative Advisor) reminded members about the official NCERA-57 project and the new five-year plan (http://nimss.org/lgu_v2/homepages/outline.cfm?trackID=16036).


Members are notified that a report of any/all funding received by each individual researcher (NCERA-57 members) should be provided, just as the publication and other reports.


Dr. Hamernik also mentioned a new funding opportunity that was launched in 2014 by the USDA NIFA: the Critical and Applied Research and Extension (or CARE) program in the 2015 AFRI Foundational Programs RFA.


The committee unanimously thanked the local organizer, Dr. Duane Davis, assisted by his graduate student, Ms. Jody Morton.


The 2016 meeting will be held at the University of Missouri, with Dr. Tim Safranski being the host and local organizer. This choice is confirmed by unanimous vote by the participant members.


The NCERA57 committee thanked Dr. Mark Diekman from Purdue University for his longtime service to the group.


Dr. Jean Feugang and Dr. Lea A Rempel are elected by unanimous vote of the participant members as, Chairman and Secretary for the upcoming year, respectively.


Both the official pointer and gavel were, once more, “reunited” for the meeting and were given to Dr. Jason Ross to have them available for the next meeting in Missouri.

Accomplishments

1. Committee members have been highly productive in terms of publications related to reproduction in swine. Only full papers (63 accepted or published) are provided in the current minutes. Numerous abstracts were presented at various professional and (inter)national scientific meetings.<br /> <br /> 2. Further characterization of miRNA signatures and roles during oocyte maturation and embryonic development are provided.<br /> <br /> 3. Lewis X trisaccharides of oviduct glycans contribute to the sperm-oviduct binding process. <br /> <br /> 4. Nanotechnology is proposed as a new and viable approach to apply in swine reproduction.<br /> <br /> 5. Studies support the new miniature swine model of retinitis pigmentosa as a viable animal for biomedical research.<br /> <br /> 6. The Fourier Harmonic Analysis could be used for uncompensable trait measurements (sperm nuclear shape variations), in relation to male fertility.<br /> <br /> 7. Two gene products transcribed into functional proteins are identified in pig tissues: the gonadotropin releasing hormone receptor 2, in testis and germ cells and interleukin-1 beta 2, in elongating conceptus.<br /> <br /> 8. Various thermal stress conditions are identified to investigate the pre- and post-natal effects of heat stress on swine productivity parameters.<br />

Impact Statements

1. A potential role of estrogen in fetal organogenesis leading to intrauterine growth retardation is suggested (USDA/ARS-NEA).
2. Acceptable pregnancy rates and litter sizes can be obtained with 2 billion frozen-thawed boar spermatozoa. However, the combination of traditional and novel laboratory assays for sperm function is necessary for effective prediction of the fertility of cryopreserved boar spermatozoa (IL).
3. Alternatives for efficient management practices of sow/gilt productivity (e.g., split-suckling, regulation of uterine capacity) are developed (KS, USDA/ARS-USMARC).
4. Attachment of post-thawed boar spermatozoa to oviduct cells may be more indicative of in vitro sperm function than tradition motility and acrosome integrity (IL).
5. Data show that efficient management and better (hormonal) control of reproductive events improve gilt and sow reproductive performances (IL).
6. Gestational and transgenerational effects of heat stress are demonstrated on various measurements of swine productivity parameters (IA, MO).
7. In utero fetal growth development is influenced by sex status of adjacent fetuses, which could be potential source of variations in post-natal behavioral and reproductive differences (USDA/ARS-USMARC).
8. It is shown that season (warm vs. cool) and cryopreservation affect the sperm nuclear shape, while the motility of frozen-thawed spermatozoa of both seasons remains comparable (USDA/ARS-USMARC, WI).
9. Large- and small-scale profiling studies interrogate porcine reproductive tissues, gametes, or embryos for further description of the effects of environmental factors on gene expression (IA, MS, NE).
10. Oviduct fluid and epithelium ligands have important regulatory effects on boar sperm function before fertilization (IL).
11. The utilization of nanotechnology tools is provided as novel approaches to investigate gametes quality and male fertility (MS).
12. Various research- and farm management-based data are generated for decision-making to reduce weaning-to-estrus interval in sows (IL, KS).

Brief Summary of Minutes

Accomplishments

<p>Committee members acknowledged the growing concern of uterine prolapses in today&rsquo;s industry and made commitments to initiate investigations. Several labs are looking into the marketing of putative assays to assist with swine production. These areas of research include; the use of nanotechnology to filter/purify semen prior to insemination, glycan and sperm receptor interactions to enhance fertility, and identifying biomarkers that can assist with identifying young pigs that will have a reduced growth trajectory.</p><br /> <p>Several participants had recently applied for funding from the National Pork Board for a special boar seasonality call.&nbsp; Dr. Tim Safranski and colleagues received the proposal funding in which heat-stress upon boars will be evaluated.&nbsp;</p>

Brief Summary of Minutes

Brief Minutes of the NCERA-57 Multistate Committee on Swine Reproduction Meeting

Mississippi State University, Starkville, MS

May 20 – 21, 2019

May 20, 2019

The meeting, held at the Mississippi Agriculture and Forestry Extension Service (MAFES) Conference Center (Bull Barn), was called to order at 8:44 am on May 20^th by Committee Chair, Kara Stewart (Purdue).  In attendance were:  Dave Miller (Illinois), Jason Ross (Iowa), Jean Feugang (Mississippi), Tim Safranski (Missouri), Brett White (Nebraska), Beth Hines (Pennsylvania), Kara Stewart (Purdue), Lea Rempel (USMARC) and John Parrish (Wisconsin).  Jean Feugang provided an overview of the schedule for the 2-day meeting.

Opening remarks were provided by Dr. George Hoffer (Dean and Director of the Agricultural Experiment Station).  First, Dr. Hoffer sent regards from Deb Hamernik (Administrative Advisor) who was unable to attend the meeting this year.  Next, he provided an overview of the student demographics at Mississippi State University as well as within the Department of Animal and Dairy Sciences and the Department of Poultry Science.  Dr. Wes Berger (Associate Director for Research) described the breakdown of research funding from partners, extramural granting agencies and commodity groups.  Finally, Dr. John Blanton (Head of the Department of Animal and Dairy Sciences) discussed the make-up of the Department of Animal Science including their four primary focus areas:  1) Teaching; 2) Reproductive Physiology; 3) Growth and Development; and 4) Nutrition. Dr. Blanton also presented additional information regarding the student population in the Department of Animal and Dairy Sciences.  The meeting agenda was reviewed and approved.  Brett White (Nebraska) made a motion to approve the minutes from the previous meeting as read and Tim Safranski (Missouri) seconded the motion.  The minutes were unanimously approved.

At 9:40 am, station reports were presented and discussed for USMARC, Wisconsin and Iowa.  Lea Rempel (USMARC) discussed her work on the relationship between piglet growth and lactation in sows as parities increase as well as investigations of the metabolome and microbiome of milk from sows.  John Parrish (Wisconsin) briefly described the changing paradigm in graduate education and a discussion ensued regarding whether the committee could become involved in a multi-institutional online course related to swine reproduction.  Dr. Parrish also provided an overview of his research studies examining:  1) the effects of scrotal insulation on histology of the testis; 2) activation of heat shock transcription factor 1 in somatic and meiotic cells; and 3) whether PG-600 could offset the effects of heat stress in the boar.  Jason Ross (Iowa) described studies examining estrous synchronization and stress stimuli during the follicular and luteal phases of the estrous cycle in gilts, the intraovarian heat shock protein response to heat stress, and health factors associated with vaginal prolapses in sows.  The committee suspended activities to take a lunch break at 12:30 pm.

In the afternoon, the first order of business was the election of new officers. Brett White (Nebraska), current secretary, will become the new chair of the committee.  John Parrish (Wisconsin) made a motion to elect Beth Hines (Pennsylvania) as secretary and Kara Stewart (Indiana) seconded the motion.  The motion passed unanimously.  Next, we proceeded with additional station reports.  Dave Miller (Illinois) discussed his recent work on sperm storage and binding in the porcine oviduct including: 1) ABHD2, a non-genomic receptor for progesterone on sperm; 2) evaluation of proximal and distal droplets on sperm within the epididymis; and 3) the core transcriptome of sperm storage organs.  Jean Feugang (Mississippi) described studies with metal and carbon-based nanoparticles for sperm selection, potential use of nanoparticles (based on lysosomes) for delivery in live animals and intrafollicular injection of nanoparticles.  

At 3:00 pm, members of the committee were provided an enjoyable tour of the new Meat Lab as well as the animal facilities at Mississippi State University.  The group returned for dinner at the MAFES Conference Center.  Following dinner, the committee discussed details of the 2020 biennial symposium.  Kara Stewart (Indiana) volunteered to host the 2020 meeting.  Potential topics for the symposium including technology, gilt development and sow productivity/longevity were debated.  Members agreed that “managing the high-performance sow” would be an appropriate topic and sow farm decision makers would be the target audience for the 2020 biennial symposium in Indiana.  Additional details will be discussed via email or video conferencing.  At 7:30 pm, the meeting was adjourned for the day.

May 21, 2019

The committee resumed its annual meeting at 8:30 am on May 21, 2019.  The remaining station reports were presented.  Tim Safranski (Missouri) discussed a project he was developing to provide research and training opportunities to undergraduate students at the University of Missouri.  This included the acquisition of funds for students to attend both scientific and producer meetings.  Next, Kara Stewart (Purdue) presented results of a reproductive technology survey sent to swine producers, especially regarding the adoption of post-cervical AI on sow farms.  She also discussed the lipidome profiles from vaginal smears in Day 2 piglets may have biomarkers of colostrum intake.  Brett White (Nebraska) provided an overview of his work utilizing a swine line with reduced endogenous levels of the porcine GnRH-II receptor (GnRHR-II KD). Results from experiments examining the luteal phase of the estrous cycle in gilts were reported. The last station report was presented by our new member, Beth Hines (Pennsylvania). Details of the swine facilities available at Penn State University as well as the programmatic goals of Dr. Hines were described.

The committee thanked Jean Feugang (Mississippi) for graciously hosting the meeting and the wonderful hospitality. John Parrish (Wisconsin) was recognized for his excellent efforts in preparing the recent rewrite for the NCERA-57 Committee. In addition, thanks were given to Dr. Wes Berger (Associate Dean for Research) for providing funding support for the meals. Lastly, the members thanked the Meat Laboratory (supervised by Tim Armstrong and Joseph Mangano) for the superb meals provided throughout the meeting. The meeting was adjourned at 11:15 am.

Respectively Submitted,

Brett White – Secretary

NCERA-57 Technical Committee on Swine Reproduction

Accomplishments

<p>1) Committee members have been highly productive in terms of publications related to reproduction in swine. Only peer-reviewed manuscripts (53 accepted or published) are provided in the current report. In addition, 32 abstracts were presented at various professional and scientific meetings.</p><br /> <p>2) A survey of U.S. swine breeding herds regarding pelvic organ prolapse in sows identified several different risk factors needing further investigation.</p><br /> <p>3) Determined that producers can administer OvuGel to sows in proestrus or estrus on d 4 post-weaning, followed by a single insemination 24 hours later, and achieve similar performance as sows inseminated multiple times upon detection of estrus.</p><br /> <p>4) Demonstrated that the secretions of cumulus oocyte complexes can trigger the release of sperm from oviduct epithelial cells and that release of sperm from the sperm reservoir within the oviduct is induced by progesterone action through CatSper channels.</p><br /> <p>5) A survey of swine producers to determine their likeliness to adopt reproductive technologies such as post-cervical artificial insemination (PCAI), indicated that cost was the most important factor.</p><br /> <p>6) Illustrated that high concentrations of circulating progesterone during early gestation influences within-litter birth weight variation in pigs.</p><br /> <p>7) Identified several putative metabolites that change within the uterine milieu as porcine embryos transition between spherical, ovoid, and tubular conceptuses.</p><br /> <p>8) Determined that if a heat stress event was detected or predicted, administration of PG600 to boars could mitigate the impact on spermatogenesis.</p><br /> <p>9) Ovulation rate was reduced in GnRH-II receptor knockdown compared to littermate control gilts, despite no difference in weight of the ovaries between lines.</p><br /> <p>10) On Day 10 of the estrous cycle, circulating progesterone concentrations were lower in GnRH-II receptor knockdown vs. littermate control gilts.</p><br /> <p>&nbsp;</p>
