The meeting was called to order Kwame by Matthews, current chair of the project. After his welcome to the group, station reports were presented in alphabetical order of institutions. The Delaware State University report was presented by Kwame Matthews, followed by Louisiana State University by Jim Miller, University of Maryland by Susan Schoenian, University of the Virgin Islands by Bob Godfrey, Virginia State University by Dahlia O’Brien, and West Virginia University by Scott Bowdridge. Station reports were followed by the business meeting. Robert Godfrey, Administrative Advisor, briefly stated that the project was in mid-cycle and that there are no updates. Christy Batcher, SSASAS Secretary/Treasurer and Program Chair, discussed the new funding requirements associated with now hosting meeting as SSASAS separate from SAAS. A tentative amount of $1,500 of required funding was mentioned in the future. The group discussed options of collecting a registration fee for SCC-81 ($25 to $50) in addition to SSASAS registration, identifying sponsors for the SCC-81 meeting (Scott Bowdridge suggested approaching the Katahdin association), and hosting the meeting independently at participant institutions as is the case for NCERA-214. The group did not settle on a final solution but opted to pursue a combination of registration fees and sponsorship. The next meeting in 2020 will be held in Chattanooga, TN, January 25-28.
It was noted that the current official participant list does not reflect members currently attending the meeting. Station reports were submitted by Fort Valley State University and North Carolina A&T University, but there was no member present from these institutions. Tuskegee University was represented and presented a report, but is not formally a member of the project. The University of Florida (Raluca Mateescu) and University of Georgia (Todd Calloway) are official members that have never been in attendance. There is a need to update/purge the participant list, and recruit new active members to the group from both 1862 and 1890’s institution.
The members elected Jim Miller, Louisiana State University, as the new secretary. The group further discussed having mini-symposium on parasite control with a focus on nematode trapping fungus. The officers will reach out to the SCERA-41 project (Beef cattle forage utilization project) to explore this as joint symposium between the two projects, as SCERA also meets in conjunction with SSASAS.
After a lunch break the group reconvened for a mini-symposium on ‘Implementing Small Ruminant Animal Care Guidelines’. The symposium was chaired by Stephan Wildeus who presented a brief overview on the subject and also discussed guidelines at Virginia State University. Other speakers were Scott Bowdridge who discussed guidelines and implementation at West Virginia University, and Kwame Matthews who discussed guidelines and implementation at Delaware State University. The presentations were followed by a roundtable discussion, concluding the mini-symposium.
Additional presentations were made by Langston University (Art Goetsch) and Berry College (Jay Daniel) providing an overview of their small ruminant programs, followed by the Tuskegee University station report (Olga Bolden-Tiller). The meeting was then adjourned.
Accomplishments
Under Objective 1: ‘Utilization of gastrointestinal nematode (GIN) control methods including selective deworming, forage/grazing management, and animal selection for GIN resistance’, Louisiana State University reported on the administration of a novel compound (X) twice on fecal egg counts and nematode development in sheep. Compound X did not definitively control the nematode population, after administration twice, compared to the results of daily administration in a previous study. However, most of the treated animals did respond (lower FEC) after the 2 treatments. There appears to be a specific effect on female Haemonchus fecundity.
Tuskegee University reported a meta-analysis on the effectiveness of different methods for minimizing Haemonchus contortus infestation in small ruminants. The results show that there is a lot of variation on the effectiveness of different methods used for controlling H. contortus in small ruminants, and no single method is able to get rid of the parasite, thereby indicating the need for an integrated approach.
West Virginia University reported on breed differences in monocyte activity in response to H. contortus larvae. The data suggested alternative activation is essential for monocyte-induced larval morbidity. St. Croix derived monocytes preferentially become alternatively activated in response to H. contortus L3, whereas Suffolk display an early classical activation status. Also, data suggested paralytic activity of IL-13, however the scope and role of IL-13 in the clearance of H. contortus remains unexplored. A further study on the effect of Texel sires on lamb performance and economics demonstrated that Texel-sired lambs required fewer dewormer treatments, and were compositionally more desirable when marketed yielding a higher sale price. A second study on Texel sheep evaluated their immune response to H. contortus, and results indicate a novel mechanism of parasite resistance centered on the adult worm and egg life stages which utilized both cellular and humoral components. In the Texel this results in adult worm establishment but little egg shedding. Consequently, pasture contamination is reduced in the Texel and this, in combination with the Texel’s greater market acceptability, make the breed a unique terminal sire for sheep producers across the world in parasite burdened regions. Another project determined the role of neutrophils in response to H. contortus. Results showed that while no breed differences were observed, data indicate that neutrophils preferentially respond to HcLA compared to HcWA, implicating neutrophils as an effector cell responsible for initiation of early Th2 responses during H. contortus infection in sheep. These data indicate impairment in SUF neutrophils ability to respond to GIN parasites.
Under Objective 2: ‘Emphasis of forage feeding systems for year-round grazing to meet nutritional requirements that mitigate drought and other plant and animal stressors’, Tuskegee University reported several studies on woodland grazing. In assessing grazing impacts of Kiko wethers and Katahdin rams on understory light penetration in woodlands, the light penetration increased by 28-31%, and suggests wethers and rams are efficient in reducing understory vegetation, creating more open space, and reduce fuel build up that minimizes possible fire hazards. Rams were found safe to use in southern-pine silvopastures; however, non-confinement treatment would be necessary while using wethers to safeguard pine trees. Cutting treatment showed a significant effect on the vegetation preferences of rams. Ram growth decreased during woodland grazing, and maintaining low vegetation height and concentrate supplementation is recommended for integrating rams in the woodland grazing system.
Virginia State University reported on the effect of breed, sex, birth type and lambing season on growth rate of forage-reared lambs. Using accelerated mating, and evaluating a production system of breeding and lambing sub-flocks of prolific, parasite-tolerant landrace hair sheep ewes in 4-month intervals, demonstrated that lamb growth on pasture varied markedly, dependent on forage quality and biomass availability. Selected lambs reached targets weights as early as 5 months of age, and 75 to 80% reached target weights as yearlings. Results support this to be a viable system for low-input, sustainable lamb production with further improvements to be achieved through enhanced forage management.
Under Objective 3: ‘Strategies for the improvement of small ruminant reproduction’, the University of the Virgin Islands evaluated the lag between body temperature and ambient temperature in hair sheep ewes in the tropics and found the greater lag time for maximum vaginal temperature of St. Croix ewes may be a part of their adaptation to the tropical climate. These results add to the information on adaptation of hair sheep breeds to conditions of high heat and humidity. A second study evaluated the effect of water intake restrictions at weaning on hair sheep ewes and lambs in the tropics, and data show that hair sheep in the tropics do not exhibit signs of dehydration from water deprivation during a 48-h weaning process. Water deprivation does decrease udder volume which may help to manage udder health.
A joint study of the University of Maryland and Virginia State University on libido and semen quality in intact and altered (short scrotum and castrated) post-pubertal male dairy sheep lambs showed ram lambs rendered short-scrotum by 10 days of age had reproductive behavior similar to intact post-pubertal rams, but ejaculate characteristics showed them to be sterile. Two additional studies at the Virginia State University evaluated sperm motion characteristics of ram semen liquid-stored in a milk egg yolk extender at four temperatures and different rates of egg yolk inclusion. Results suggested storage at 10°C may be a viable alternative to storage at 5°C, and 15% (v/v) as an optimal inclusion level of egg yolk for chilled storage of ram semen when using motility as an indicator of semen quality.
Under objective 4: ‘Disseminate research results and information to stakeholders’ Delaware State University hosted the Delaware Small Ruminant Field Day (Prevention, Detection and treatment of Infectious Disease in Sheep and Goats) and two Integrative Parasite Management workshops. Fort Valley State University hosted several parasite management and training workshops, and created a fact sheet on Integrated Parasite Management Best Practices. A number of programs on smart drenching, and integrated parasite management practices were conducted through Louisiana State University. North Carolina A&T State University held a presentation on Raising Resilient Goats at their Small Farms Field Day.
Tuskegee University hosted a University Goat Day, a Master Goat Producers Certification Training Program, a Prevet Club Open Goat Show, and the 3rd Annual National Goat Conference. The institution also conducted an Integrated Approach for Managing Diseases and Parasites in Small Ruminants Education Program, a Sustainable Agroforestry Practices Education Program, a Sustainable Year-Round Forage Production and Grazing/Browsing Management Education Program, and a small ruminant workshop for pre-veterinary students during the 2018 American Pre-Veterinary Medical Association National Symposium. The University of Maryland conducted a 4-H Small Ruminant Research Academy, and hosted its 5th Twilight Tour & Tasting with exhibits highlighting the many products produced by small ruminants: meat, dairy, fiber, and vegetation control. Virginia State University conducted programs on ‘Starting a Sheep and Goat Meat Enterprise’, and ‘Sustainable Integrated Parasite Management in Small Ruminants’, and hosted is annual Small Ruminant Field day with the theme “Keeping your sheep and goats healthy”.
Impacts
- At Delaware State University the Small Ruminant Field Day provided participants with an increased knowledge on diseases that are transmissible to and can be detrimental to small ruminants. Ninety-one percent of participants acquired new information pertaining to small ruminant biosecurity, small ruminant diseases, and keeping animal(s) alive by doing the right thing, while 87% gained knowledge and plans to create a biosecurity plan, be more careful when vaccinating and use the required vaccinations on your animal(s), and be more careful when handling and feeding animals to prevent the infection and/or spread of infectious/zoonotic diseases. In two Integrative Parasite Management training programs the participants developed skills in conducting fecal egg counts and FAMCAHA© scoring. Many of them indicated they felt the training was useful and increased their knowledge in small ruminant internal parasite management. Nine of the producers indicated that they will be using FAMCAHA© scoring before deworming their animals. Post conference evaluations returned showed that 75% of participants rated the overall workshop as excellent and the remaining 25% as good with all the participants believing the information was given in a clear and concise manner.
- At Fort Valley State University 213 participants attended Integrated Parasite Management and Fecal Egg Counting (FEC) training programs for small ruminants of which approximately 128 certified. Many participants indicated they felt the training was useful. In a ‘Sericea Lespedeza for Integrated Parasite Management’ parasite management workshop 61 participants received information, and 20 farmers were recruited for participating by planting 5 – 10 acres of Sericea Lespedeza.
- Tuskegee University reported on a Pasture and Grazing Management Education Program aimed at changing the face of small-scale livestock operations in Alabama. The changes in behavior and condition of livestock producers after their participation in various educational events relevant to sustainable pasture improvement and grazing management were assessed. Most respondents (n=30) mentioned that they implemented the learned knowledge and skills on their farms. Majority of them mentioned that their condition improved significantly because of the implementation in terms of grazing opportunity (96%), animal performance (67%), animal health (69%), and soil quality (89%). The respondents plan to continue beneficial practices, such as improve and manage pastures sustainably (77%), improve grazing systems (87%), plant suitable grass and leguminous forages (63-73%), develop/improve silvopastures (50%), and develop woodland grazing (37%) to sustain their operations. Lack of resources (time, money, and farm machinery) was the major reason for some of the respondents (14%) who could not implement the learned skills and knowledge. Because of this program, numerous livestock farmers and extension professionals are being trained every year (n=80-119/year), and many more have access to educational materials (2,200-2,400/year). Impact evaluation of the program showed that knowledge and skills of the trainees increased significantly (35-44%), and several trained farmers are implementing the pasture improvement and sustainable grazing management practices.
- Also at Tuskegee University a Master Goat Producers Certification Training Program trained 16 participants from four states and 2 countries, including agricultural professionals, graduate students and producers, and increased their knowledge on goat management. Furthermore, a grantsmanship workshop resulted in an increased awareness of funding opportunities for producers. An Integrated Approach for Managing Diseases and Parasites in Small Ruminants Education Program provided 40 producers, county agents, and technical assistant personnel with increased knowledge and skills (62%) on the presented topics. Participants rated the presented topics as very useful (4.8/5.0) and applicable (4.7/5.0) and would benefit them greatly if applied (4.5/5.0).
- Activities at the University of Maryland Sheep Research & Extension Program resulted in several sheep producers indicating that they plan to make scrotum ram lambs so that they can manage their lamb crop as one group, three youth being exposed to scientific (field) research, 100 people sampling lamb, goat, and (sheep and goat milk) cheese and learning about the sheep research program at the University of Maryland’s WMREC, thousands of University of Maryland students and faculty had the opportunity to sample lamb at the dining halls (for many, it was their first exposure), and Maryland’s only licensed sheep dairy farm received a premium price for their male lambs, which improved the viability of their dairy enterprise.
- At Virginia State University a program on Starting a Sheep and Goat Meat Enterprise resulted in increased knowledge for 90 producers and agents on starting a small ruminant meat enterprise. Six workshops on Sustainable Integrated Parasite Management in Small Ruminants increased knowledge in 110 producers, agents and youth on small ruminant internal parasite management, resulted in 30 small ruminant producers receiving FAMACHA© certification, and 50 youth developing skills in conducting fecal egg counts. At Virginia State University’s annual Small Ruminant Field Day 75 participants were provided an increased knowledge on small ruminant diseases and their prevention and treatment.
