“…A sample from the caudate lobe of the liver was removed and frozen until analyzed. Age of deer was determined using cementum annuli analysis of collected incisors (Gilbert, 1986). Collection methods followed recommendations of the American Society of Mammalogists (Animal Care and Use Committee, 1998) and were approved by the Institutional Animal Care and Use Committee at South Dakota State University.…”

ABSTRACT:Because there is a paucity of information on the mineral requirements of free-ranging deer, data are needed from clinically healthy deer to provide a basis for the diagnosis of mineral deficiencies. To our knowledge, no reports are available on baseline hepatic mineral concentrations from sympatric white-tailed deer (Odocoileus virginianus) and mule deer (Odocoileus hemionus) using different habitats in the Northern Great Plains. We assessed variation in hepatic minerals of female white-tailed deer (n542) and mule deer (n541). Deer were collected in February and August 2002 and 2003 from study areas in Custer and Pennington Counties, South Dakota, in and adjacent to a wildfire burn. Hepatic samples were tested for levels (parts per million; ppm) of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), boron (B), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K), selenium (Se), sodium (Na), sulfur (S), thalium (Tl), and zinc (Zn). We predicted that variability in element concentrations would occur between burned and unburned habitat due to changes in plant communities and thereby forage availability. We determined that Zn, Cu, and Ba values differed (P#0.05) between habitats. Because of the nutritional demands of gestation and lactation, we hypothesized that elemental concentrations would vary depending on reproductive status; Cd, Cu, Ca, P, Mn, Mo, Na, and Zn values differed (P#0.05) by reproductive status. We also hypothesized that, due to variation in feeding strategies and morphology between deer species, hepatic elemental concentrations would reflect dietary differences; Ca, Cu, K, Co, Mo, Se, and Zn differed (P#0.05) between species. Further research is needed to determine causes of variation in hepatic mineral levels due to habitat, reproductive status, and species.

“…Reproductive status was determined by examining the uterus for fetuses and mammary glands for milk. Incisors were removed and aged using cementum annuli analysis (Gilbert 1986). Body weights (total and eviscerated) were recorded to the nearest kilogram and rumen-reticulum contents were recorded to the nearest 0.1 kg.…”

Age can be precisely estimated from the number of cement zones in stocks of roe deer living in Hungarian habitats. Growth zones of the cement stock can be assessed also on dental slides; however, it is more exact with histotechnical methods, first of all with the Goldner trichromium, Heidenhain azan and Giemsa dying.In the case of roe deer, age estimation is not applicable with slide techniques on the basis of secondary dentin, since the prepared dental slides presenting the secondary dentin did not show any sing of age-related layers in the sample of analysis. On the other hand histological examinations can be successfully applied just like in the case of the cementum. Age estimation by tooth wear yields very close, statistically verifiable correlation with the age estimated form cement zones. Crown height of the molars exhibit strong, statistically proven relationship with the age estimated from cement zones, except the P 1 teeth. In all the samples the strongest relation appears for the total average of molars. Highly close relation can be observed in the case of M 1 , M 2 and M 3 teeth. Length parameters of I 1 teeth indicate a statistically verifiable relation with the age estimated from cement zones. The angle of I 1 teeth and the age estimated from cementum shows no proper relation, consequently this parameter is not indicative of age.Dry matter content of the lens in bucks is intensive up to the first year of age, becoming statistically negligible in the succeeding years. On the other hand, lens weight of does keeps growing up to approximately 5 years of age.According to RAJNIK (1977) there is a close, statistically verifiable relation between the estimated ages of does coming from cement zones and from the nasal septum. Examining the nasal septum of does gives appropriate information on age.On-site age estimation of live roe-deer is an acceptable procedure complying with practical requirements, but the professional experience, training and precision of the person performing the estimation fundamentally determines the reliability of the method.Considering that in a given case trophy judgement may result in imposing sanctions against a hunter or a person entitled to hunting, the accuracy of this method is not acceptable. According to our study the age estimated from cement zones was only in an average agreement of 37.6% with age estimation coming from trophy judgement.KULCSSZAVAK: őz, Capreolus capreolus, kor-megállapítási módszerek KEYWORDS: Roe Deer, Capreolus capreolus, age estimation methods, BEVEZETÉSA természetközeli vadállomány szabályozás, okszerű vadgazdálkodás kivitelezésekor az öko-lógiai és ökonómiai szempontokat is kielégítő vadállomány kialakításához, a vadgazdálkodási tervezéshez, a hivatalos trófeabírálathoz a korbecslési módszerek ismerete szükséges.Magyarországon az ejtett trófeás nagyvad, így az őzbak ejtésének szakszerűségét a vadászati hatóság állapítja meg a hivatalos trófeabírálat során.
