Turkey poults were offered ad libitum a diet containing 2.5 g salt/kg and tap water containing, 0, 90 or 105 mn NaCl to drink from 1 to 12 d of age. 2. High mortality with oedbema and ascites occurred mainly from 5 to 8 d in poults given the saline solutions. Mortality seemed to be related to salt and water intakes. 3. Plasma and body composition indicated abnormal retention of salt and water in poults younger than 12 d of age offered hypotonic saline. 4. In a second experiment using the same diet poults were offered hypotonic saline (105 mn NaCl in tap water) from 5, 9 or 13 d of age. High mortality with oedema and ascites was only observed when saline was given from 5 or 9 d. 5. The results suggest that from about 5 to 10 d of age there is a relative functional renal insufficiency which causes susceptibility to the toxic effects of saline water. 相似文献

Observations of erratic anthelmintic activity of fenbendazole against known standardised thiabendazole-resistant strains of Haemonchus contortus and Trichostrongylus colubriformis in sheep were investigated. Fenbendazole at a dose rate of 10 mg/kg body weight was administered by oral, intra-ruminal or intra-abomasal routes, and was most effective against both resistant strains following intra-ruminal administration. In addition thiabendazole, oxibendazole, fenbendazole, parbendazole and mebendazole plus two unrelated compounds, levamisole and morantel tartrate, were used at one and a half times their suggested or recommended therapeutic dose rate against thiabendazole-resistant strains of H contortus and T colubriformis in sheep; each drug being administered by the intra-ruminal or intra-abomasal routes. Fenbendazole was more effective against both strains following intra-ruminal administration. Parbendazole was more effective against the resistant strain of T colubriformis following intra-ruminal administration. At the dose rate chosen for the other benzimidazoles used against these resistant strains, there was no difference in anthelmintic efficacy due to route of administration. Levamisole was highly effective against both resistant strains, irrespective of the route of administration. In the groups treated with morantel tartrate, the results obtained were difficult to interpret due to mortalities and a highly variable response in the surviving sheep. Fenbendazole, thiabendazole and mebendazole when used at their suggested or recommended therapeutic dose rate in sheep, were highly effective against known thiabendazole-susceptible strains of H contortus and T colubriformis following both intra-ruminal or intra-abomasal administration. 相似文献

Generalized demodicosis was diagnosed in a 14-year-old castrated male domestic short-hair cat. No underlying disease was detected. The cat responded incompletely or poorly to commonly recommended treatment, but responded well to total body dipping with 0.0125% amitraz at weekly intervals. 相似文献

A method of assessment of cases of rupture of the anterior cruciate ligament with a view to prescribing either surgical or conservative treatment is described. The results of treatment of the cases after such an assessment indicates that the majority of small dogs will recover to satisfactory function after 2 months enforced rest, but large breed and working dogs require surgical intervention for successful treatment.
Résumé. Les auteurs décrivent une méthode propre à évaluer les ruptures du ligament cruci-forme antérieur en vue de prescrire soit l'intervention chirurgicale, soit le traitement conserva-teur. Les résultats thérapeutiques obtenus sur la base de cette évaluation portent à conclure que chez le chien de petite taille, 2 mois de repos forcé permettent le plus souvent d'obtenir un rétablissement fonctionnel satisfaisant, tandis que chez les chiens de grande taille et chiens d'utilité, l'intervention chirurgicale s'impose.
Zusammenfassung. Es wird eine Methode zur klinischen Beurteilung von Fällen einer Ruptur des vorderen Kreuzbandes im Hinblick auf die Möglichkeit einer chirurgischen oder konservativen Behandlung beschrieben. Die Behandlungsergebnisse bei den Fällen nach einer solchen Beurteilung zeigen, dass die Mehrzahl von kleinen Hunden sich in 2 Monaten Zwangsruhe zu einer zufriedenstellenden Funktion erholt, grosse Rassen und Arbeitshunde aber einen chirurgischen Eingriff zur erfolgreichen Behandlung benötigen. 相似文献

The genomes of U.S. bluetongue viruses, an Australian bluetongue virus, and three other related orbiviruses were analyzed by polyacrylamide gel electrophoresis. The genomes were comprised of ten segments of double-stranded (ds) RNA. Estimates of the molecular weights of the dsRNA segments revealed that the U.S. bluetongue serotypes were remarkably similar. Although the dsRNA profiles of the viruses exhibited common segments, each virus had a distinct dsRNA profile. The usefulness of the genome analysis as a diagnostic tool for identification and for epidemiologic studies is discussed. 相似文献

The avermectins are macrocyclic lactones produced byStreptomyces
avermitilis. One of them has been chemically modified and given the non-proprietary name invermectin. The compounds have shown efficacy against various stages of filarial parasites. With respect to pre-adult stages in the mammalian host, activity has been observed againstDirofilaria
immitis in ferrets and dogs, andDipetalonema
viteae andLitomosoides
carinii in jirds (Meriones); but activity has not been observed against the developing stages ofBrugia spp. in jirds orOnchocerca spp. in cattle. The compounds have not shown activity against adult filarial worms, except in the case ofSetaria
equina in horses and possiblyDipetalonema
viteae in jirds. With respect to the first stage larva (microfilaria) in the mammalian host, efficacy has been observed againstDirofilaria
immitis in dogs,Brugia
malayi in multimammate rats (Mastomys),Dipetalonema
viteae andLitomosoides
carinii in jirds andOnchocerca spp. in horses and cattle; but activity has not been observed against microfilariae ofBrugia
pahangi in jirds or cats. Efficacy against filarial parasites has been observed following oral or parenteral administration of drug, sometimes at extremely low dosage. For example, a single oral dosage of 0.05 mg/kg was highly active against the third and fourth larval stages and microfilariae ofD.
immitis in dogs. 相似文献

1. There was a marked strain difference in the incidence of hepatic haemorrhage in White Leghorn hens receiving dietary rapeseed meal (RSM). 2. Tolerance to high dietary contents of RSM also varied between individual birds within a strain. 3. Glucosinolates were implicated in the development of hepatic haemorrhage among hens receiving dietary RMS but the exact relationship was not clear. 相似文献
