Accomplishments and Impacts
For Objective 1: Develop ecologically and economically sound land management practices that use the unique harvesting abilities of sheep and goats for: a) managing and sustaining native plant communities; b) controlling invasive, exotic plant species; and c) improving nutrient cycling and pest management in range and cropping systems. Descriptions of potential impacts and applications were presented addressing the use of sheep as a control of leafy spurge and spotted knapweed in Montana (Montana State University). The impact sheep and goats have on the control of pine encroachment was presented with the potential impact on reclaiming lands that quit producing herbaceous forage since the encroachment of pine (Montana State University). Potential benefits of using Fecal NIRS to monitor spotted knapweed consumption was reported by Montana State University to better estimate animal consumption. Pre-weaning exposure of lambs to slender false brome was reported to have potential for developing lambs into efficient and economic tools for controlling slender false brome (Oregon State University). Though not present at the meetings, a report was submitted describing the impact of sheep and cattle on controlling leafy spurge over 10 years and another was sent reporting on the use of rotational grazing and multi-species grazing as potential control mechanisms of leafy spurge for the past 10 years (North Dakota State University). A special seminar was presented by Texas A&M University and Angelo State University faculty on the benefits of combining fire, sheep, goat, and rotational grazing for controlling invasive woody plant species on western rangelands.
For Objective 2: Develop sheep and goat management strategies that enhance the efficiency for production of high quality, marketable end products by: a) improving biological efficiency through better understanding of environmental and genetic events that influence meat and fiber production; b) identifying unique feedstuffs that enhance the nutritional value of meat; c) utilizing state-of-the-art instrumentation both in the field and in the lab to accurately and rapidly measure important characteristics of wool, mohair, and cashmere; and d) develop animal identification systems that ensure the accurate real-time linking of animals to lifetime genetic, performance, health, and origin database. Descriptions of potential benefits of identifying changes in ewe body weight and lamb production over a period of three years were reported (USDA-ARS, Sheep Experiment Station) and a report was given describing the benefits of a web based sheep ration formulation system. The system is accessible to the general public and is expected to assist producers better manage their sheep nutrition (Montana State University). Montana State University also reported on the benefit of using ultrasound measurements in rams to facilitate selection for improved carcass merit of their offspring by understanding the relationship between sire and offspring characteristics. Potential benefits of using hormone treatments post breeding to improve neonatal lamb survival were presented and understanding the time of lamb loss in a range sheep operation is vital to improving sheep production efficiency. (New Mexico State University). Benefits of using various sire breeds to improve lamb production and pounds of lamb weaned in a reduced input sheep production system were reported (Oregon State University). Consumption of toxic plants is a critical concern of sheep producers and the impact of the consumption of potato-weed was presented along with the benefits of better understanding the mechanism the toxin has on pregnancy (Angelo State University). Potential economic benefits of using the OFDA2000 to separate lots of wool by predicting fineness pre-shearing to better capture price premiums was reported (Texas A&M University).
For Objective 3: Rapidly and accurately disseminate new information to the producer through: a) development of novel technology transfer platforms; b) hosting field days at research centers; and, c) organizing on-farm demonstration projects. Potential benefits and impacts of combining sheep and goat associations during field days and seminars to more efficiently present information to producers was reported (Utah State University).
