本文采用饱和盐水漂浮法对徐州市郊区散养奶牛消化系统寄生虫进行了初步调查。粪检结果表明:该地区散养奶牛消化系统寄生虫的总感染率为83.19%(94/113),所获寄生虫13种,隶属于10科13属。通过对各种寄生虫的感染率,不同调查点、不同年龄奶牛寄生虫的感染率及混合感染情况等进行分析,认为徐州市郊散养奶牛寄生虫感染率高,混合感染普遍,应加强寄生虫防治。  相似文献

The objective of this study was to compare the application of different in vitro and in situ methods in empirical and mechanistic predictions of in vivo OM digestibility (OMD) and their associations to near-infrared reflectance spectroscopy spectra for a variety of forages. Apparent in vivo OMD of silages made from alfalfa (n = 2), corn (n = 9), corn stover (n = 2), grass (n = 11), whole crops of wheat and barley (n = 8) and red clover (n = 7), and fresh alfalfa (n = 1), grass hays (n = 5), and wheat straws (n = 5) had previously been determined in sheep. Concentrations of indigestible NDF (iNDF) in all forage samples were determined by a 288-h ruminal in situ incubation. Gas production of isolated forage NDF was measured by in vitro incubations for 72 h. In vitro pepsin-cellulase OM solubility (OMS) of the forages was determined by a 2-step gravimetric digestion method. Samples were also subjected to a 2-step determination of in vitro OMD based on buffered rumen fluid and pepsin. Further, rumen fluid digestible OM was determined from a single 96-h incubation at 38°C. Digestibility of OM from the in situ and the in vitro incubations was calculated according to published empirical equations, which were either forage specific or general (1 equation for all forages) within method. Indigestible NDF was also used in a mechanistic model to predict OMD. Predictions of OMD were evaluated by residual analysis using the GLM procedure in SAS. In vitro OMS in a general prediction equation of OMD did not display a significant forage-type effect on the residuals (observed - predicted OMD; P = 0.10). Predictions of OMD within forage types were consistent between iNDF and the 2-step in vitro method based on rumen fluid. Root mean square error of OMD was least (0.032) when the prediction was based on a general forage equation of OMS. However, regenerating a simple regression for iNDF by omitting alfalfa and wheat straw reduced the root mean square error of OMD to 0.025. Indigestible NDF in a general forage equation predicted OMD without any bias (P ≥ 0.16), and root mean square error of prediction was smallest among all methods when alfalfa and wheat straw samples were excluded. Our study suggests that compared with the in vitro laboratory methods, iNDF used in forage-specific equations will improve overall predictions of forage in vivo OMD. The in vitro and in situ methods performed equally well in calibrations of iNDF or OMD by near-infrared reflectance spectroscopy.  相似文献

Information gathered from cases of fowl cholera (FC) in commercial turkey flocks through case records, flock records, and telephone and mail surveys was used to estimate disease costs. The cost to the Georgia commercial turkey industry in 1986 from preventive measures, treatment of outbreaks, and production losses from the disease was estimated at $634,545. The cost of FC per kg of live production was estimated to be $0.015.  相似文献

In 2007, 678 pigs of all age groups out of 347 different farms from Lower Saxony and Northrhine-Westphalia and 86 persons occupationally exposed to pigs were investigated for their nasal colonisation with methicillin-resistant Staphylococcus areus (MRSA) by the Field Station for Epidemiology of the University of Veterinary Medicine Hannover and the Robert Koch-Institute. At the individual animal level, a frequency of positive results of 13% (n = 85 positive animals) and at the herd level, a frequency of positive results of 18% (n = 62 positive herds) were found. All isolates were assigned to the Multilocus Sequence Typing Type ST398. Within MRSA-positive herds, there were more MRSA-negative than MRSA-positive animals. Among the occupationally exposed persons (veterinarians, laboratory personnel and meat inspection personnel), 20 persons (23%) showed a nasal colonisation with MRSA ST398. A quite strong association between the intensity of the contact to pigs with the frequency of nasal colonisation in the occupationally exposed persons was detected. None of the animals or the humans nasally colonised by MRSA ST398 showed any clinical symptoms of a staphylococcal infection. Conclusions are drawn on the herd and intra-herd prevalence of the nasal colonisation of pigs with MRSA ST398 in pigs, but especially on which questions need to be addressed by further research.  相似文献

Summary Parvaquone was tested in cattle infected withTheileria annulata when they were presented at clinics in the vicinity of Baghdad. Out of over 200 cases presented with suspected theileriosis between July 1984 and July 1985, the drug was used in 45 cases where theileriosis was confirmed by microscopic examination of blood and lymph node biopsy smears. Twenty seven of the cases were considered mild and 18 cases severe. Weights of the cattle were estimated and parvaquone was administered by intramuscular injection at a nominal dose of 20 mg/kg. A single treatment with parvaquone was used in 25 cases and 20 cases were treated twice but there was no correlation between severity of disease and the number of treatments given. Twelve cases (27%) also received antibacterial therapy. All cases were in exotic cattle or cattle born from exotic (imported) cattle and 64% of the cases were in cattle under six months of age. Temperatures dropped immediately after treatment and the majority were normal (below 39.5°C) by two to three days after the first treatment. Of the 45 cases treated 43 recovered. This compares very favourably with a previously reported mortality of 66% in untreated imported cattle in Iraq.
Eficacia Del Parvaquone En El Tratamiento De La Theilerosis Natural En Ganado En Iraq
Resumen Se trató ganado infectado conTheileria annulata en forma natural con parvaquone, en clínicas veterinarias localizadas en la vecindad de Baghdad. De 200 casos admitidos con sospecha de theileriosis, entre julio 1984 y julio 1985, la droga se usó en 45 casos confirmados mediante el examen microscópico de frotis de sangre y biopsias de ganglios linfáticos. Veintisiete de los casos se consideraron moderados y 18 casos severos. Se estimaron los pesos de los animales enfermos, suministrandoles parvaquone vía intramuscular en dosis nominales de 20 mg/kg (rango 16–35 mg/kg). Se utilizó un solo tratamiento con parvaquone en 25 casos clínicos, mediante la aplicación de una sola inyección y se aplicaron dos inyecciones en 20 casos (doble tratamiento), sin que se encontrara correlación alguna entre la severidad de la enfermedad, recuperación y número de tratamientos. Doce casos (27%) recibieron también algún tratamiento antibacteriano. Todos los casos de theileriosis se presentaron en ganado exótico o nacido de ganado exótico (importado) y 64% de los casos ocurrieron en ganado bajo los seis meses de edad. La temperatura bajó inmediatamente después del tratamiento, normalizándose dos o tres días después de tratamiento (bajo 39.5°C). De los 45 casos tratados 43 se recuperaron. Se informa una mortalidad previa de 60% en ganado importado no tratado contra theileriosis en Iraq.

Efficacite De La Parvaquone Pour Le Traitement De La Theileriose Naturelle Des Bovins En Irak
Résumé La parvaquone a été essayée pour le traitement de bovins infectés parTheileria annulata lorsqu'ils étaient présentés aux cliniques des environs de Bagdad. Sur plus de 200 cas présentés pour suspicion de theilériose entre juillet 1984 et juillet 1985, le médicament a été utilisé dans 45 cas où la theilériose était confirmée par l'examen microscopique du sang et de biopsies de ganglions lymphatiques, 27 cas étaient considérés comme des atteintes modérées et 18 comme des cas graves. Les poids des animaux étaient estimés à l'oeil et la parvaquone administrée par voie intra-musculaire à la dose normale de 20 mg/kg (soit 16 à 35 mg/kg). Un traitement unique à la parvaquone a été pratiqué dans 25 cas et il a du être renouvelé dans 20 cas mais il n'y avait pas corrélation entre la gravité des symptômes et le nombre de traitements requis. Dans 12 cas (27%) une thérapie antibactérienne a également été mise en oeuvre. Tous les malades étaient des animaux importés ou issus d'animaux importés et dans 64% des cas les animaux étaient âgés de moins de 6 mois. Les températures ont chuté immédiatement après le traitement et, pour la plupart, étaient normales (moins de 39°5) deux à trois jours après le traitement—sur 45 animaux traités, 43 ont guéri. Ces résultats apparaissent très favorables par rapport à la mortalité de 66% rapportée antérieurement et affectant les bovins non traités en Irak.
