Progress 05/01/10 to 04/30/15
Outputs Target Audience:The primary target audience was the general public (meat consumer) to demonstrate a frozen reindeer meat product was equivalent to fresh. Alaskan Natives own the majority of reindeer in Alaska. Workshops have been targeted towards Alaska Native reindeer producers and the general public desiring to learn technical skills to support the reindeer meat industry. 4H students are increasing the use of reindeer as livestock market animals. 4H students focusing on raising reindeer for meat production have been requesting specific workshops to meet their needs. Meat retailers were provided supporting evidence from this project that a frozen reindeer meat product was just as good, or better than fresh. Restaurant owners and chefs benefited through the development of a project cookbook that demonstrated a frozen product was as marketable as fresh. Members of rural Alaskan villages were brought to Fairbanks for demonstrations of USDA-inspected slaughter techniques for reindeer. A workshop for rural Alaskan Natives was sponsored at Delta Meats and Sausage to observe an USDA inspected slaughter. Participants were allowed on the killing floor during the entire slaughter process to observe techniques and to consult with workers and a USDA inspector. The progress report for the effect of haylage on meat quality was presented at Reindeer Herders Annual meeting in Nome, Alaska and to a nation-wide group of reindeer producers at their annual conference. Reindeer meat production lectures were presented to the business leaders of Fairbanks. A public service lecture was given to the public in Fairbanks with over 100 people were in attendance. The lecture was sponsored by the UAF Science for Alaska lecture series and can be seen at http://www.uaf.edu/scienceforalaska/watch-fairbanks-lectures/ Presentations, 'Taste of the Tundra' were given at the Northwest campus in Nome, Alaska followed by a tour of the reindeer facilities. This was timed to coincide with the Iditarod Race in Nome .Approximately 25 people attended. A workshop/consultation on reindeer husbandry and meat production was presented to a Fairbanks 4H club.

What opportunities for training and professional development has the project provided? Members of rural Alaskan villages were brought to Fairbanks where a demonstration USDA inspected slaughter of rendeer was sponsored at local slaughter and processing facility. Participants were allowed on the killing floor during the entire slaughter process to observe techniques and to consult with workers and a USDA inspector. This project provided training for reindeer producers and one-on-one time discussing and planning future sales and marketing of reindeer meat. This project also provided training for novice reindeer owners who want to sell retail in their business. Provided one-on-one mentoring for undergraduate and graduate students interested in meat science and food production. Provided knowledge and training to slaughter plant owners, restaurants and mobile food units across the state regarding shelf life and quality of reindeer meat. In August 2014, members of an Alaskan Native Youth Camp participated in a reindeer meat production workshop at the University of Alaska Fairbanks.

What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts What was accomplished under these goals?
Alaska has the range and forage resources to produce substantial quantities of red meat through the production of reindeer, a commodity much in demand commanding a high price. Feeding reindeer a predominately forage (haylage) rather than a milled (concentate) diet during winter will likely reduce cost of production, but its effect on animal production and nutritional qualities of the meat is unknown. Alaska is a large state with limited road infrastructure so it is difficult for producers to meet the year-round demand for reindeer meat with a fresh product. However, demand could be met by producing and delivering a frozen product that can be stored for future use. The marketability of reindeer meat was expanded through this project, thus improving the economics of reindeer meat operations. Key outcomes have come mostly in the way of providing knowledge and opportunity in the industry. Reindeer physiological restraints along with current management practices allow fresh reindeer meat to only be available seasonally. A consistent supply of fresh reindeer meat is unavailable year round. This project demonstrated that reindeer meat can be frozen and stored for a one year time period without compromising quality. Reindeer meat that was previously sold seasonally can now be marketed year round at a premium price because this project demonstrated a frozen and stored reindeer meat product is comparable to fresh. Changes in knowledge: This results of this project provided important insight on the cost cutting implications and animal production and meat quality of feeding haylage to reindeer. Reindeer demonstrated an aversion to long stem haylage (Smooth Brome grass) but readily consumed a fine stem haylage (Wheatgrass). This project also demonstrated that reindeer on a primarily Wheatgrass haylage diet during winter maintained or gained body weight. Haylage can be fed to reindeer during winter to offset the high cost of feeding a concentrate diet. Knowledge gained from this project will help support the current efforts to establish mobile slaughter facilities in rural Alaska communities with a knowledgeable and well trained work force to consistently provide a high quality product to distant markets. The marketability of a previously seasonal product was expanded to making it available year round without compromisisng qualty.

What do you plan to do during the next reporting period to accomplish the goals? This project will end in April. Work will continue on marketing reindeer meat as funding allows. The next research proposal has been submitted and is being reviewed on predator control.
Impacts What was accomplished under these goals?
Two year old reindeer steers were slaughtered and Longissimus dorsi muscle samples were collected fresh while replicate samples were frozen and thawed and evaluated at 1 week, 4 and 12 months. Longissimus steak samples from the 12 month frozen treatment group underwent sensory, shear force, TBARS (rancidity), proximate analysis, amino acid and fatty acid profiles and water holding capacity (WHC) determination and analyzed for the fresh, fresh frozen 6 month and one year frozen periods of time. Shear force values were not significantly different amongst treatment groups (P=0.99). Proximate analysis showed no significant difference in moisture, ash and protein content while lipid content was significantly different across treatment groups (P = 0.99, 0.99, 0.99 and >.01 respectively). Tenderness and juiciness attributes were not significantly different among treatment groups (P=0.92 and P=0.60) however, an off flavor attribute was significantly different (P=0.028) amongst treatment groups suggesting that off flavor diminishes with freezing. While not detected in sensory evaluation, mean TBARS (rancidity) values increased significantly (P >.01). Results of this study suggest reindeer meat can be frozen for up to a year without compromising quality. Knowledge gained from this project will help support the current efforts to establish mobile slaughter facilities in rural Alaska communities with a knowledgeable and well trained work force to consistently provide a high quality product to distant markets. This project also provided important insight on the cost cutting implications and animal production and meat quality of supplemental feeding of haylage to reindeer.

Alaska has the range and forage resources to produce substantial quantities of red meat through the production of reindeer, a commodity much in demand commanding a high price. Feeding reindeer a predominately forage (haylage) rather than a milled (concentate) diet during winter will likely reduce cost of production, but its effect on animal production and nutritional qualities of the meat is unknown. Alaska is a large state with limited road infrastructure so it is difficult for producers to meet the year-round demand for reindeer meat with a fresh product. However, demand could be met by producing and delivering a frozen product that can be stored for future use. The major goals of this project are: Evaluate the acceptance of haylage to reindeer and evaluate the effects of a predominately haylage diet during winter on reindeer production and the physical and chemical characteristics of meat. Determine physical and chemical changes in fresh reindeer longissimus steaks frozen for 1 week, 4 and 12 months. Develop recipes and cooking methods that will ameliorate negative changes in reindeer meat quality due to freezing and that is acceptable to restaurants and their clientele. Changes in knowledge Reindeer demonstrated an aversion to Smooth bromegrass haylage likely to the relatively high fiber concentration. Reindeer readily consumed wheatgrass haylage and maintained body weight through winter even though the DMI of a milled ration was restricted to 0.75% of body weight per day high. However, reindeer steers fed only wheatgrass haylage during winter lost weight compared to animals when fed adlib a milled ration. Two year old reindeer steers were slaughtered and Longissimus dorsi muscle samples were collected fresh while replicate samples were frozen and thawed and evaluated at 1 week, 4 and 12 months. Longissimus steak samples from the 12 month frozen treatment group underwent sensory, shear force, TBARS (rancidity), proximate analysis, amino acid and fatty acid profiles and water holding capacity (WHC) determination and analyzed for the fresh, fresh frozen 6 month and one year frozen periods of time.

The haylage feed trial experiment was conducted to determine effect on meat quality. Collaboration was initiated with Rural Nutritional Services Program (Interior Aleutians Campus) to begin developing traditional native Alaskan recipes for publication. The effect of haylage on meat quality progress report was presentation at Reindeer Herders Annual meeting in Nome, Alaska Events: A workshop on reindeer husbandry and meat production was presented to the Kenai 4H in January. In February, the Tundra Gold presentation on meat quality and production was presented to the public at the Westmark Hotel. Over 100 people were in attendance. This was sponsored by the UAF Science for Alaska lecture series and can be seen at http://www.uaf.edu/scienceforalaska/watch-fairbanks-lectures/.

PROJECT MODIFICATIONS: Not relevant to this project.
Impacts Changes in knowledge Analysis from the fresh, fresh frozen 6 month and one year frozen samples show mean TBARS (rancidity; P=9.85e-9), moisture (P=.008666), protein (P=.003717), ash (P=.00001999) and lipid (P=4.212e-9) values were significantly different across treatment groups. Shear force values (P=0.2432) were not significantly different across treatment groups. Juiciness attributes were not significantly different across groups (P=.5267). Tenderness attributes were significantly different across groups (P=.04291). The off flavor attribute changed significantly (P=0.0001353) across treatment groups suggesting off flavor diminishes with freezing. Purge values were significantly different across treatment groups (P=1.406e-10). Cooking loss values were taken for treatment times one, two and four and were also significantly different across these groups. Results of this study suggest that freezing and frozen storage of reindeer meat retains and/or increases quality within some of the meat attributes, which may increase the market potential and profitability of the reindeer meat industry. Analysis making comparisons between individual interactions is yet to be determined. This project will provide important insight in determining the effect of supplemental feeding of haylage to reindeer and potential cost cutting implications to a feeding regime A mobile slaughter facility with educated work force will provide an outlet for product to reach market and support local industry.

Progress 01/01/11 to 12/31/11
Outputs OUTPUTS: Highlighted activities included longissimus steak samples from the 12 month frozen treatment group underwent sensory, shear force, TBARS (rancidity), proximate analysis, amino acid and fatty acid profiles and water holding capacity (WHC) determination. A haylage feed trial experiment was conducted to determine animal intakes and performance during the winter. We collaborated with chefs at the Culinary Arts Department, University of Hawaii in cooking and development of 15 recipes and professional photos. Events included an abstract submission and poster display, "The effects of freezing and storage time on the quality of reindeer (Rangifer tarandus tarandus) meat (M. longissimus dorsi)", was presented at the Institute of Food Technologists at New Orleans, LA. Meat cutting workshops were also held in Stebbins, Savoonga, Golovin, Nome, and Fairbanks, Alaska. A 2 credit course, High Latitude Range Management F160 Meat Production was delivered in Nome, Alaska. A Meat Quality progress report was presented at the Reindeer Herders Annual meeting in November. Services included providing information consistently on reindeer meat production to the public and 4H/Cooperative Extension members via phone and e mail. Information was disseminated through tours and demonstrations of the mobile slaughter plant in Nome, Alaska directed at reindeer herders with direct implication for production and marketing within the industry. PARTICIPANTS: Peter Bechtel, USDA /ARS laboratory for analysis; University of Illinois sensory analysis team University of Hawaii culinary school; Eva Wiklund, National Union of the Swedish Sami People; George Aguiar, MS student, UAF/SNRAS, Animal Meat Science and Greg Finstad, Reindeer Research Program, UAF. TARGET AUDIENCES: Alaskan Natives own the majority of reindeer in Alaska. Workshops have been targeted towards reindeer producers and anyone wanting to learn technical skill for the industry. By increasing commercial production for market, rural economy could be stimulated providing an additional source of income for reindeer producing communities in Alaska. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts Changes in knowledge Preliminary analysis from the fresh, fresh frozen and 4 month frozen samples show mean TBARS (rancidity; P=0.16) and shear force values (P=0.09) were not significantly different across treatment groups. Tenderness and juiciness attributes were not significantly different across groups (P= 0.09 and P=0.99). The off flavor attribute changed significantly (P=0.00016) across treatment groups suggesting off flavor diminishes with freezing. Preliminary results of this study suggest that freezing and frozen storage of reindeer meat retains and/or enhances quality which will increase the market potential and profitability of the reindeer meat industry. This project will provide important insight in determining the effect of supplemental feeding of haylage to reindeer and potential cost cutting implications to a feeding regime. A mobile slaughter facility with an educated work force will provide an outlet for product to reach markets and support local industry.
