| Abstract | Ein Rehgehörn ist niemals völlig trocken und hat niemals ein konstantes Gewicht. Ab- und Zunahmen des Gewichts hängen wesentlich von der Luftfeuchtigkeit und dem Gehalt der Stangen und des Schädels an einer Restfeuchte ab.Von entscheidendem Einfluß auf das Gehörngewicht ist, wie der Schädel gekappt und präpariert ist. Es ist ein Irrtum anzunehmen, etwas Mehr oder Weniger an Schädelmasse sei vernachlässigbar. Es sollte angestrebt werden, nur Böcke zu bewerten, die nach der IF gekappt sind (Tabellen 1–6).Der Gewichtsverlust eine Gehörns nach dem Herrichten in Abhängigkeit von der Zeit hängt nicht vom Ausgangsgewicht des Gehörns ab. Es ist nicht auszuschließen, daß schwächere Gehörne mitunter mehr Gewicht als stärkere verlieren (Tabellen 7–10).Die Gewichtsschwankungen beziehen sich sowohl auf den Schädel als auch auf die Stangen. In grober Näherung sind beide bei einem Gehörngewicht von 250–300 g gleichermaßen beteiligt.Gewichtszunahmen durch erhöhte Luftfeuchtigkeit erfolgen schneller als sie bei erniedrigter Luftfeuchtigkeit wieder abnehmen (Tabellen 11–15).Die erhobenen Befunde erklären einige Schwächen bei der Bewertung von Rehgehörnen nach der IF. Es werden Vorschläge gemacht, diese Schwächen zu beseitigen.A roe deer trophy is never completely dry and never has a constant weight. An increase or decrease in weight primarily depends upon the humidity and the moisture content remaining in the prongs and skull.The manner in which the skull was capped and prepared are a decisive influence in the weight loss of the antlers. It is an error to assume that a bit more or less of skull mass is negligible. Only buck trophies that have been prepared according to the IF should be evaluated (Table 6).The weight loss of a trophy after preparation in relation to time does not depend upon the original weight of the antlers. The possibility that smaller antlers may incur a greater weight loss than larger ones cannot be excluded (Tables 7–10).The variations in weight refer to the skull as well as to the antlers. As a rough estimate both contribute about equally to the variations with an antler weight of 250–300 g.Weight gains due to increased humidity occur faster than weight loss at low humidity (Tables 11–15). The presented results explain some of the weaknesses in the evaluation of roe deer trophies according to the IF. Some proposals are put forth to eliminate these weaknesses.Un trophée de Chevreuil n'est jamais complètement sec et ne présente jamais un poids constant. L'augmentation ou la diminution du poids dépend essentiellement de l'humidité de l'air et de la teneur des bois et du têt en eau résiduelle.Pour la masse du trophée, la découpe du crâne et la préparation du trophée sont déterminantes. C'est une erreur de croire que l'on peut négliger un faible excédent ou un faible déficit de masse du crâne. Il convient de veiller à ne mesurer que des trophées dont la découpe respecte les stipulations de la formule internationale. (Tabl. 1 à 6).La perte de poids d'un trophée après préparation ne dépend pas de sa masse de départ. Il n'est pas exclu que des trophées de faible poids enregistrent des pertes de poids plus importantes que des trophées de poids élevé (Tab. 7 à 10). Les variations de poids concernent autant les bois que le crâne. Ces pertes s'équilibrent pour des poids situés entre 250 et 300 gr.Les gains en poids liés à une humidité élevée de l'air sont plus rapides que les pertes que l'on observe dans un milieu sec (Tabl. 11–15).Ces constatations constituent autant de lacunes de la formule de mensuration des trophées de Chevreuil. Des propositions sont faites pour les éliminer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
