Clipboard, Search History, and several other advanced features are temporarily unavailable. COVID-19 is an emerging, rapidly evolving situation. Prairie voles are small rodents found throughout the United States. Supplementation with calcium chloride did not affect litter frequency or size but did improve postnatal growth and survivorship. The fact that colonies of various species of voles have been maintained successfully on natural-ingredient diets formulated for rabbits, rats, and mice suggests that supplementation concentrations of vitamins used for these species may be adequate. 254-285 in Biology of New World Microtus, Special Publication No. Tab will move on to the next part of the site rather than go through menu items. In experimental trials adult (≥20 g), singly housed meadow voles consumed diets containing up to 2.8 percent potassium for 4 weeks without adverse results (Mickelson and Christian, 1991). SOURCES: Lee and Horvath (1969), Richmond and Conaway (1969), Lindroth et al. J. Nutr. Biol Reprod. Provo, Utah: American Society of Mammalogists. Postnatal growth rates were measured in the first weeks postpartum; daily growth rates after weaning can be expected to be similar or somewhat greater. More recently, laboratory and field research on voles has focused on the effect of nutritional and other environmental factors on reproduction and population growth (e.g., Cole and Batzli, 1979; Nelson et al., 1983; Batzli, 1985, 1986; Hasbrouck et al., 1986; Spears and Clarke, 1987; Hall et al., 1991). They are common on prairies, ungrazed pastures, weedy areas, fallow fields, road right-of-ways, and are also sometimes in alfalfa or soybean fields. Body weight, litter size, and energetics of reproduction in Clethrionomys gapperi and Microtus pennsylvanicus. Click here to buy this book in print or download it as a free PDF, if available. J. Mammal. TABLE 7-1 Reproductive and Developmental Indices of Voles. Populations of voles may vary in characteristics such as body mass and litter size, although the extent to which this variation is a result of genetic or environmental effects is not clear (Keller, 1985). Provo, Utah: American Society of Mammologists. The effects of increased dietary cellulose on the anatomy, physiology and behavior of captive water voles, Arvicola terrestris. Weaning is at 2 to 3 weeks old and the first molt is at around 24 days old. Population dynamics of the meadow vole (Microtus pennsylvanicus) in nutrient-enriched old-field communities. HFD-fed voles pair-housed with voles maintained on the HFD demonstrated increased weight relative to pair-housed voles that were both maintained on chow. Agron. It is not known if the nutritional requirements of these genera differ from Microtus, but because of differences in natural diet, body size, and physiological adaptations to the environment (Batzli, 1985; Woodall, 1989) they will not be included in this discussion. Prairie voles are small rodents found throughout the United States. Comp. Michigan Agric. Seasonal acclimation to temperature in the prairie vole, Microtus ochrogaster. ), and water voles (Arvicola sp.). Care 19:88–91. Cole, F. R., and G. O. Batzli. Sci. Some of the male-female pairs practice monogamy, whereas other males and females will mate with multiple partners (a polygynous mating system). Artificial diets for use in nutritional studies with microtine rodents. Throughout the world there are about 155 species of voles. Cherry, R. H., and L. Verner. 1984. Comp. Epub 2011 Aug 13. The volume also provides an expanded background discussion of general dietary considerations. Although volatile fatty acids are produced. Rapid reproductive rates are also characteristic of voles when food is abundant. According to IUCN, Prairie vole is common and widespread throughout its range but no overall population estimate is available. Lindroth, R. L., G. O. Batzli, and S. I. Avildsen. Voles, also known as meadow mice, are herbivores that feed on grasses, tree bark, roots, tubers, and vegetable crops. The Fourth Revised Edition presents the current expert understanding of the lipid, carbohydrate, protein, mineral, vitamin, and other nutritional needs of these animals. 14:167–179.

Of the 10 species listed by Mallory and Dieterich (1985), 7 have been maintained on rabbit diets and 7 on mouse breeder diets. Nelson, R. J., J. Kark, and I. Zucker. USA.gov. J Comp Physiol B. Diet and Nutrition Prairie voles are herbivorous and their food includes the soft basal parts of grasses, roots and tubers, as well as seeds, which they may store underground. Yokota, H. 1988. Provo, Utah: American Society of Mammologists. Fertil. The scientific name of the Prairie vole, ‘Microtus ochrogaster’, comes from the Greek, with the genus name translating as "small ear" and its specific name meaning "yellow belly". Voles are able to compensate for an increase in dietary fiber concentrations by an increase in mass of the gastrointestinal tract and especially the cecum (Gross and Wang, 1985; Hammond and Wunder, 1991). 116:246–255.

Nutritional ecology of microtine rodents: Digestibility of forage. Jpn. Biochem. Ecol. 1975. They eat solid foods by12 days. J. Mammal. The genus Microtus encompasses about 60 species, if Pitymys is accepted as a subgenus of Microtus (Corbet and Hill, 1980; Nowak and Paradiso, 1983; Anderson, 1985). It is widely found across the midwest, in grasslands and upland fields. Due to their choice of diet, Prairie voles have an important part to play in nutrient cycling within prairie ecosystems and also as prey for many predator species (raptors, owls, snakes, weasels, foxes). National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Ecol. Activity: Prairie voles are active year round both day and night. Dieterich, R. A., and D. J. Preston. Activity during the day increases in winter and decreases during the summer. Mallory, F. F., and R. A. Dieterich. There was a significant correlation between serum leptin and carcass fat mass in animals maintained in the HFD/HFD housing paradigm such that carcass fat mass predicted serum leptin levels (r. Adult male and female prairie voles were housed with same-sex voles and maintained on a LFD or HFD for 19 weeks prior to treatment onset (N=4–6/group).  |  Blevins JE, Graham JL, Morton GJ, Bales KL, Schwartz MW, Baskin DG, Havel PJ.
