From the Director’s Desk
In the Summer 2017 newsletter, I announced that Dr. Arthur Goetsch had been awarded membership into the American College of Animal Science, which was a high honor. I am once again extremely proud to announce that Dr. Goetsch has been inducted into the Illinois State University Hall of Fame. This is a great honor and we are extremely happy for Dr. Goetsch and his family. He is very deserving of this honor and you can read more about it on page 3. Recently, Dr. Goetsch was a member of a team that visited Purdue University on a Faculty Visitation Exchange. Other members of the team included
Drs. Phillip Lewis (Rehabilitation Counseling), Orlenthea McGowan (School of Education), and Steve Zeng (School of Agriculture & Applied Sciences). The objective of the visit was to share strategic priorities and organizational context, to explore existing capacities and potential project ideas around faculty interests, and to build and strengthen faculty relationships. We hope that this visit will be fruitful for Langston University and will result in a lasting partnership in agriculture teaching and research. Purdue University is renowned for its innovative research in agriculture, especially precision agriculture. Students and scientists at both universities would mutually benefit from this partnership. Every year, our scientists write grants for the USDA 1890 Institution Teaching, Research and Extension Capacity Building Grants (CBG) Program and generally, we are successful in being awarded grants. The year 2018 was a very good year and we received a record number of grants from the CBG Program. I have listed the title of the grants and the principal investigators. Suffice it to say
Winter 2018
that the principal investigator will lead the projects but it will take a team of scientists and farm and laboratory staff to conduct successfully the projects and experiments. • LINC 2.0 - Enhanced goat management and educational tool (Dr. Ryszard Puchala). • Sky Wrangler: Smart application of precision livestock farming for grazing animals and pasture management (Dr. Terry Gipson). • Sustainable use of saline water by ruminant livestock species (Dr. Arthur Goetsch). • Certification in a Moodle box (Dr. Roger Merkel). • Establishing a large animal teaching center to enhance teaching capacity and student experiential learning at LU (Dr. Steve Zeng). • Enhancement of undergraduate academic, research experience at LU by interlinking biotechnology and horticulture practices (Dr. Kanyand Matand). I hope that 2018 was a good year for you and your goats and I hope that 2019 will even be better.

Research Spotlight Greenhouse Gas - Dairy Goats. Fifty-four Alpine doelings (70 lbs body weight and 306 days of age) were allocated to nine treatments individually fed for ad libitum intake of 25% concentrate and 75% forage diets (dry matter basis; DM). Alfalfa was the forage in the control diet. Other diets contained Sericea lespedeza as the forage, with 1.25% DM of quebracho extract included in the concentrate fraction for a dietary condensed tannin level of 8.4%. Lespedeza treatments were no additive (L) and inclusion of monensin (I) at 22 ppm or 0.000022% DM (L-I), soybean oil at 3% (L-S), coconut oil at 3% (L-N), I and 3% soybean oil (L-I-S), I and 3% coconut oil (L-I-N), 1.5% soybean oil and 1.5% coconut oil (L-S-N), and I, 1.5% soybean oil, and 1.5% coconut oil (L-I-S-N). The experiment was 12 weeks with two 6-week periods. Gas exchange was determined in weeks 6 and 12, and other measures occurred in weeks 5 and 11. There were differences between the control treatment and diets with lespedeza in intake of DM (3.2, 2.8, 2.8, 2.6, 2.9, 2.5, 2.4, 2.5, and 2.2 lbs/day for control, L, L-I, L-S, L-N, L-I-S, L-I-N, L-SN, and L-I-S-N, respectively). Ruminal methane emission was less for diets with lespedeza than for the control in MJ/day (1.36, 0.76, 0.84, 0.71, 0.71, 0.66, 0.65, 0.68, and 0.68) and relative to intake of gross energy (5.92%, 3.27%, 3.49%, 3.19%, 2.84%, 2.91%, 3.20%, 3.20%, and 3.27%) and digestible energy (11.19%, 6.98%, 7.40%, 6.38%, 5.90%, 5.69%, 6.37%, 6.38%, and 6.70% for control, L, L-I, L-S, L-N, L-I-S, L-I-N, L-S-N, and LI-S-N, respectively). In conclusion, the magnitude of effect of condensed tannins from lespedeza and quebracho extract on ruminal methane emission by Alpine doelings did not diminish over time and was not markedly influenced by dietary inclusion of monensin, soybean oil, or coconut oil.
Greenhouse Gas - Meat Goats. Mature Boer goat wethers were supplemented with 0.5% body weight rolled corn and consumed pelleted alfalfa (CON), pelleted Sericea lespedeza (HSL; 6.4% condensed tannins), a 1:1 mixture of alfalfa and lespedeza (MSL), or alfalfa with monensin (ION; 22 mg/kg), coconut oil (CCO; 4%), or soybean oil (SBO; 4%). Total dry matter intake in the 20-week study (3.86%, 3.75%, 3.52%, 3.69%, and 3.64% of body weight) and total tract OM digestibility determined every 5 weeks (72.8%, 69.5%, 70.3%, 72.0%, and 71.1%) were not affected by treatment, although there were differences in nitrogen digestion (77.5%, 70.7%, 67.0%, 77.0%, 75.7%, and 73.6% for CON, MSL, HSL, ION, CCO, and SBO, respectively). Ruminal methane emission was not influenced by period and was lowest among treatments for CON expressed as percentages of gross (10.3%, 6.8%, 6.3%, 7.2%, 6.5%, and 6.5%) and digestible energy (14.8%, 10.2%, 9.3%, 10.6%, 9.8%, and 10.1% for CON, MSL, HSL, ION, CCO, and SBO, respectively). In conclusion, both levels of lespedeza elicited similar depressions in ruminal methane emission, with a magnitude of change similar to that of an ionophore and coconut and soybean oils, and effects did not vary with week of the study.

3rd National Goat Conference The third National Goat Conference was held in September 2018 in Montgomery, AL and hosted by Tuskegee University. The first National Goat Conference was held in 2010 at Florida A&M University. The second was held in 2013 at North Carolina A&T University. More than 250 participants attended the rd 3 National Goat Conference (NGC) and learned about a wide variety of topics. Several Langston University personnel participated in the NGC with Drs. Terry Gipson, Steve Hart, and Roger Merkel presenting. Dr. Gipson presented on "Central Performance Testing: Purpose, Benefits, Impacts, and Trends" and "History of the U.S. Goat Industry," Dr. Hart on "Grazing System and Management for Goat Production," Dr. Merkel on "Mortality Dr. Roger Merkel discusses mortality composting with a NGC Composting," and Drs. Hart, Merkel, and participant. Gipson jointly on "Current Situation and Future Prospects of the US Goat Industry." The abstract of the joint presentation is presented below. In addition to the oral presentations, Dr. Arthur Goetsch presented two posters on internal parasite research. Current Situation and Future Prospects of the US Goat Industry Steve Hart, Roger Merkel, and Terry Gipson American Institute for Goat Research Langston University, Langston, OK Current demand for goat meat in the US outstrips domestic supply. There is great potential for industry growth in the meat and dairy sectors. Whereas fiber prices have improved, loss of animals and market resources, labor costs for shearing, and lack of animal genetic resources will prevent growth in the short term. As producers age, there is opportunity for new producers to enter the marketplace. Significant challenges exist, such as access to local markets and abattoirs, dewormer resistant parasites, and feed costs. Establishing goat feedlots can increase meat supply and industry commercialization. Technologies used for cattle will be expanded for use in goats with interconnected sensors collecting health and production data. The field of genetic improvement will change from current production testing to identifying superior animals at an early age using DNA analysis. A quality assurance program is needed to address animal welfare issues and promote consumption of domestic products to consumers. Page 6

Required
Introduction to Dairy Goats
Elective
Nearly one year ago, we unveiled the Dairy Goat Online Certification course (http://goats.langston. edu/Online Certification) and we are happy to report that 80 participants have been certified as Quality Producers (QP). To qualify for certification, a participant must successfully complete all of the 18 core modules and 7 of the 10 elective modules. The vast majority (76 of 80) of QP are from the United States. Fore each module, the participant will first take a pre-test. Once the pre-test is scored, then the participant will have access the module content. If the participant scored less than 85% on the pre-test, then the participant will be required to take the post-test. The objective of the pre-test is to measure knowledge before reading module content. The objective of the post-test is to measure knowledge after reading module content. The participant has one attempt at the pre-test and an unlimited number of attempts at the post-test. The pre- and post-test scores of the 1,063 participants enrolled in the QP course can be seen in the table to the right. The modules are listed in Tableof-Content order and generally, participants follow this order but they have the flexibility to study the modules in any order. The average score for pre-test is 67.8% and the post-test is 97.5%. This is an average difference of 29.7%, a significant increase in knowledge transfer. For the 80 QP, the average time needed to complete the course is 54 days with a range of 3 to 322 days and a median of 27 days.
