To summarize everything we have learned in these three articles, here is your take home message: Thank you so much for reading this article series on reindeer nutrition, diets and feeding! Especially males have been observed to eat lichen in the wild during summer and can benefit from it. Reindeer will use their hooves and antlers to dig through the top layer of snow, to get to the living tundra below. The reindeer still plays an integral part in the lives of many native Arctic people, who may use the creature for food, clothing, travel and other resources; by using their bones and antlers. 2013, Intake and chemical composition of winter and spring forage plants consumed by semi-domesticated reindeer (Rangifer tarandus tarandus) in Northern Finland, Animal Feed Science and Technology, 185 (3-4), s. 190. There are three types of hyenas; the spotted hyena, the brown... How Your Vegan Diet Can Positively Affect Animals, This Cat Took A HUGE Risk Whilst in Labor. This could be the reason behind the idea for the famous Christmas song ‘Rudolph the red-nosed reindeer”. (This is yet another "moss" that is really a lichen.) Reindeer are herbivores, which means they only eat plant-based material called vegetation. Lichens are organisms where fungus and green algae or bacteria grow together (called a symbiotic relationship). & Mathiesen, S.D. Let’s take a quick trip down the memory lane before diving in to practical reindeer feeding: In case you missed the first two parts, you can check out the first article on nutrition here and the second article on diets here. If there is too much protein in the winter diet, the nitrogen conserved in the urea cycle and provided in the diet exceeds the needs. The transitioning to winter diet usually starts in October. As you remember, this microbial protein is the protein source of the ruminant. 1990, Variation in quality of caribou and reindeer forage plants associated with season, plant part, and phenology, Rangifer, 10 (3), s. 123-130. Mathiesen, S.D., Vader, M.A., Raedergård, V.B., Sørmo, W., Haga, O.E., Tyler, N.J. & Hofmann, R.R. Klein, D.R. The dosage can be a bit lower to mimic the natural conditions. Reindeer Moss has a taste reminiscent of mushrooms. Acta Vet Scand, 41 (1), s. 25-40. Mineral stones can have uneven ratio of vitamins and minerals and the dosage each animal gets may vary. It makes up 60–70 percent of their diet during the winter. Regular fecal scoring is advisable to know what is normal for your animals and what should raise the alarm. This lichen can be used in the making of aquavit, and is sometimes used as decoration in glass windows. Helsinki, Finland Reindeer do not suffer in the cold as their bodies and thick hide and fur, is able to withstand their harsh habitat. Ensuring your chinchilla has the correct diet is vital to their well-being. Warenberg, K., Dannel, Ö, Gaare, E. & Nieminen, M. 1997, Porolaidunten kasvillisuus, Pohjoismainen Porontutkimuselin (NOR), Landbruksforlaget. All ruminants can cycle urea in their system, and reindeer are especially efficient in this. The lichens absorbed the radioactive atoms, which were eaten by reindeer and later found in reindeer meat and milk. Tell me what topics you’d like to know more about in zoo animal nutrition. Reindeer, especially the gestating females are known to eat dead plant parts in the winter. p., Scandinavian Veterinary Press, Oslo. They also have great booklets and posters on safe browse species for different animal groups. & Nieminen, M. 1992, The effect of the diet on the digestive organ size of reindeer, Rangifer, 12 (3), s. 167-168. It needs to be fine with minimal stem and maximal leaf concentration. In captivity the amount of food is staple, but you should see a decrease in the body condition in the spring. Their noses have the ability to warm the air they breathe before it reaches their lungs, which ensures their entire body is kept at a suitable temperature. Their ability increases during winter. The amount should be kept small and is best offered first in the morning. Another way to conserve browse for winter is ensiling. They will also nurse on their mother’s milk for the first six months of their life. Being wet in subzero temperatures predisposes the animals to other health problems. Your email address will not be published. & Barboza, P.s. Staple of the diet should be high-quality browse from deciduous, non … Luckily, the Cairngorm National Park has loads of good clean air, so the lichen grows well for the reindeer to munch on! Staple of the diet should be high-quality browse from deciduous, non-toxic trees. As a supplementary feed some fresh cut hay or dried hay can be offered. Always consult a veterinarian familiar with reindeer if you have any concerns. Sørmo, W. & Mathiesen, S.D. They eat lichen a type of moss, grass, and plant that grow on rock and or trees. Reindeer also enjoy eating the leaves of willow trees and birch trees. What else? Most browser pellets are suitable for reindeer summer diets. & Booth, R. 2015, Non-invasive assessment of the interrelationships of diet, pregnancy rate, group composition, and physiological and nutritional stress of barren-ground caribou in late winter, PLoS ONE, 10 (6). Lichen-eating Reindeer vs. Chernobyl Nuclear Disaster Earlier this year I wrote about a lichen that was named after President Barack Obama in which I included a brief introduction to lichens. Therefore, it’s advisable to feed the mineral supplement separate from the lichen. The lichen can also be covered with a hard crust on top of the snow, making it impossible to dig them up. Cladonia rangifernia is a type of lichen also known as Reindeer Lichen, which reindeer will often eat in the harsh winter months. Valtonen, M. 1979, Renal responses of reindeer to high and low protein diet and sodium supplement, University of Helsinki. Keeping up with body condition scoring and fecal scoring in the winter are also important. Reindeer Moss, like most lichens are 94% carbohydrate, but 6% acid. This acid can cause severe stomach cramps if consumed in any quantity. 2017, Seasonal energy and protein requirements for Siberian reindeer (Rangifer tarandus), Journal of Mammalogy, 98 (6), s. 1558-1567. Beet pulp has been suggested as a replacement and it seems to work well in practice too. It should be high in protein and metabolizable energy and offered ad libitum, if there are no contraindications for unrestricted energy intake in the animal group. What do reindeers eat in captivity also depends on what leafy greens you have available to give them, as reindeer can safely eat their way through a whole host of vegetables like swiss chard, collard and beet greens, kale, lettuce, and cabbage. Other foragers will eat lichen and moss raw or dump it right into a soup. In the winter the hay needs to meet the same standards as in summer. Fresh cut browse is better accepted than dried browse and should be used when available. Reindeer need to have different diets during summer and winter. Soveri, T. & Nieminen, M. 2007, Papillar Morphology of the Rumen of Forest Reindeer (Rangifer tarandus fennicus) and Semidomesticated Reindeer (R. t. tarandus), Anantomia Histologia Embryologia, 36 (5), Blackwell Publishing Ltd, s. 366-370. Gaining weight during summer is important in captivity too, because the reindeer lose appetite during the winter and are unable to gain weight after Christmas. If not, your winter diet might be too high in energy and possibly also in protein. It covers immense areas and serves as pasture for reindeer, moose, caribou, and musk oxen. 1994, Food Plant Selection by Reindeer during Winter in Relation to Plant Quality, Ecography, 17 (2), s. 153-158. Hofmann, R.R. What do reindeers eat as adults do not differ much from what they eat when they are young. They are known as reindeer in Europe, but in America, wild populations of reindeer are called caribou. & Hummel, J. This can be done by giving males the summer diet for longer, even up until Christmas in some cases. 1993, Bacteria in the small intestine of lichen-fed Norwegian reindeer (Rangifer tarandus tarandus), Letters in Applied Microbiology, 16 (3), s. 170-172. During winter the reindeer become excellent in conserving energy and nitrogen obtained from the diet and catabolized from body tissues. In the winter the need for energy and especially protein is lower. Some Arctic inhabitants mixed the partly digested lichen from caribou stomachs with raw fish eggs. That’s rather clever since reindeer eat a lot of it and its branching resembles deer antlers. 2011, Functional and comparative digestive system anatomy of Arctic ungulates, Rangifer, 20 (2-3), s. 71-81. 2000b, Diet composition, rumen papillation and maintenance of carcass mass in female Norwegian reindeer (Rangifer tarandus tarandus) in winter, Journal of Zoology, 251 (1), s. 129-138. White, R.G., Jacobsen, E. & Staaland, H. 1984, Secretion and absorption of nutrients in the alimentary tract of reindeer fed lichens or concentrates during the winter, Canadian Journal of Zoology, 62 (12), s. 2364-2376.
