Zusammenfassung In Ergänzung zu Untersuchungen über die Entwicklung der Erdmaus im Freiland (Bäumler, 1979) wurden hier die Aufzucht der Erdmaus in der Gefangenschaft bei unterschiedlicher Ernährung eingehender untersucht und die Ergebnisse mit Befunden bei Wildfängen verglichen. Ganz allgemein wuchsen Erdmäuse in der Zucht bei optimaler Ernährung wesentlich schneller heran als im Freiland. Höchste tägliche Gewichtszunahmen von durchschnittlich 685 mg/Tag wurden bei gesäugten Nestlingen beobachtet. Wildfänge, die im Freiland vordem nur langsam herangewachsen waren, zeigten i. d. R. nach Überführung in die Zucht in den ersten Wochen einen deutlichen Wachstumsschub. Fütterungsexperimente zeigten ferner, daß Hunger und Mangelernährung bei Zuchttieren ähnliche Symptome auslösten, wie sie bei Wildfängen im Freiland insbesondere ab der Jahresmitte beobachtet wurden. Die Sommerkrise der Erdmaus wurde hier demnach als eine komplexe Erscheinung gedeutet, an der verschiedene Faktoren beteiligt sein können, nämlich mangelnde Nahrungsqualität, Parasitierung und unterschiedliche Wuchspotenzen der Tiere.

The summer crisis of the field vole (Microtus agrestis L.) Part II. Breeding in captivity
In addition to investigations about the development of the field vole in forest plantations in the years 1972–76 breeding experiments in the lab were carried out. The growth rates of 286 voles which were born in captivity were compared with those of 436 marked freeliving animals in a forest plantation. The development of the optimal reared voles in the lab was much faster than in the field areas. Voles which were transferred from the field to the lab showed mostly an accelerated growth within the first weeks in captivity. However seasonal changes of development of the voles were also detected in the lab. The summer crisis of the field vole seemed to be influenced by various factors whereby the quality of food, parasites especially Babesiosis and different growth potencies of the animals played an important role.

For genetic counseling this report presents a database of canine hereditary diseases and coat color characteristics, which have been solved on the molecular level.The database facilitates access to appropriate diagnostic laboratories for specific phenotypes. The recent decoding of the dog genome provides ideal conditions for the molecular genetic analysis of hereditary traits and diseases. Therefore the authors would like to encourage veterinary surgeons in particular to report cases to assist the molecular analysis of further phenotypes in future. 相似文献

Objective— To (1) evaluate the analgesic effect of percutaneous cementoplasty (PC) in dogs with primary bone tumor (PBT) of the distal aspect of the radius and (2) evaluate the impact on the course of disease by adding PC to a palliative, multimodal treatment protocol in these dogs.
Study Design— Prospective pilot study.
Animals— Dogs (n=4) with PBT of the distal aspect of the radius.
Methods— Tumor lesions were filled percutaneously with polymethylmethacrylate under fluoroscopic guidance. Pamidronate was administered once in a week before PC. Radiotherapy and chemotherapy were initiated 2 and 6 weeks after PC, respectively. Force plate analysis was performed immediately before 2, and 6 weeks after PC. Survival time was defined from PC to euthanasia.
Results— Two dogs had a significant increase in peak vertical force 2 weeks after PC ( P =.043) and remained free of lameness for 18 and 20 weeks, respectively. One dog had an acute relapse after an initially lame-free period of 10 days. The remaining dog failed to improve ( P =.686). Three dogs developed at least 2 complications including transient worsening of the lameness after PC, cement leakage, wound infection and suspected thromboembolism in combination with cough and anemia. Median survival was 4.8 months (range, 1–5.7 months).
Conclusions— PC in combination with pamidronate significantly improved lameness in 2 dogs; however, PC is not risk-free. Deep wound infection, intraarticular cement leakage, and venous thrombosis were the main complications.
Clinical Relevance— PC might be a useful addition to established palliative, multimodal treatment protocols in dogs with PBT; however, because of the complications encountered PC warrants further study before routine use can be considered. 相似文献

Among other factors (eg, bedding material, roughage), feed has an important effect on the airborne particle concentration in the stable air, in particular directly in the breathing zone of the horse during feeding. Therefore, this study was designed to analyze and compare the generation of different airborne particle fractions of diverse feed types and feed processing techniques under standardized laboratory conditions. Oats and barley as well as two commercially formulated ready-prepared pellets and two different commercially formulated ready-prepared mixes were analyzed. Oats were subjected to four different forms of processing (whole uncleaned, whole cleaned, rolled uncleaned, rolled cleaned), barley was subjected to steam flaking in addition to the same forms of processing as oats. In total, 13 feeds were analyzed. Airborne particle concentrations were detected online with a gravimetrically measuring analyzer that was equipped successively with different inlets to measure the particle fractions PM 1, PM 2.5, PM 10, and PM 20. The measurements were carried out in a closed chamber (1 × 1 × 1.5 m) including a bowl (diameter = 0.5 m), which simulated the trough. The sample inlet was situated at a height of 1.0 m above the bowl. Rolling oats and barley led to a significantly increased generation of the PM 20 fraction and a significantly decreased generation of the PM 2.5 fraction. The mechanical cleaning of oat and barley brings a clear decrease in dust generation from straights whether they are left whole or are rolled after cleaning. A considerable reduction in dust generation can be achieved if steam-flaked barley or commercially prepared feeds are used. 相似文献

Zusammenfassung
Hyadaphis tataricae (Ajzenberg), ein ernstzunehmender Schädling anLonicera tatarica L. und auf dem europäischen Kontinent nach Westen vordringend, wurde zuerst im Jahre 1935 aus Moskau beschrieben. Seit 1959 ist die Blattlaus aus Polen bekannt, und im Jahre 1962 wurde sie zum ersten Mal westlich der Oder festgestellt. Im Jahre 1964 wurde sie an vielen Stellen im Stadtgebiet von Berlin, wo sie in einigen Fällen schwere Schäden verursachte, und außerdem in Rostock gefunden. Durch den Befall werden die Spitzen der Zweige zu großen, herabhängenden, verzweigten Gallen umgebildet.H. tataricae ist eine nicht wirtswechselnde Art, denn nahezu alle oviparen Weibchen sind die Nachkommen von Ungeflügelten. AußerL. tatarica kann auchL. bella Zabel stark geschädigt werden. Einige andere Formen vonLonicera spp. werden in geringerem Ausmaß befallen.Lonicera xylosteum L. wurde frei von Befall gefunden.
Summary Hyadaphis tataricae (Ajzenberg), a heavy pest ofLonicera tatarica L. and spreading westward on the European continent, has been originally described in 1935 from Moscow. Since 1959 the aphid is known from Poland, and in 1962 it was noted for the first time west of the Oder. In 1964 it was found in many sites in the township Berlin, causing there in some cases severe damages, and also at Rostock. By the attack the tips of the branches are deformed to big hanging down and ramified galls.H. tataricae is a nonmigrating species, for nearly all oviparous females are the offspring of apterae. BesidesL. tataricae alsoL. bella Zabel may be heavily damaged. Some other forms ofLonicera spp. are infested to a minor extend.Lonicera xylosteum L. was not found to be attacked by the species.
Sommaire Hyadaphis tataricae (Ajzenberg), une espèce extrêmement nuisible surLonicera tatarica L. et se répandant sur le continent européen vers l'occident, a été décrite originallement de Moscou en 1935. Depuis 1959, ce puceron est connu de Pologne, et en 1962 il fut découvert pour la première fois à l'ouest de l'Oder. En 1964, il fut trouvé dans des lieux nombreux dans le territoire de Berlin, où il faisait naître en plusieurs cas de grands dégâts, et de plus à Rostock. Par cette attaque, les bouts des ramaux sont déformés en grandes galles ramifiées pendant en bas.H. tataricae est une espèce sans changement d'hôte, car presque toutes les femelles ovipares son les descendants d'aptères. OutreL. tatarica, L. bella Zabel peut être détérioré gravement. Plusieurs autres formes deLonicera spp. sont attaquées d'un moindre degré.Lonicera xylosteum L. n'a pas été trouvé attaqué par le puceron.相似文献
