Prediction of digestibility and energy concentration of winter pasture forage and herbage of low-input grassland--a comparison of methods.     

W Opitz v Boberfeld  P C Theobald  H Laser 《Archives of Animal Nutrition》2003,57(3):167-176

Regarding the estimation of the energy concentration or digestibility of herb-dominated forage and plant samples from winter pastures, it could be expected that the estimation is only reliable when in vitro methods with rumen fluid as inoculum (= gas production techniques) are used. For the verification of this thesis based on logical reflections, an in vitro-method with rumen fluid added as inoculum, as well as chemical, and enzymatic methods were applied under consideration of existing estimating functions. As a possible reason for the observed divergence of the methods, effects of fungal infections or, respectively, secondary compounds in herbs are discussed. At the present state of knowledge, it is adequate to estimate the energy concentration in vitro by gas tests, as far as fattening types like suckler cows and beef cattle are concerned, maybe in contrast to the forage evaluation for dairy cows.  相似文献

Incidence of Salmonellae in Captive and Wild Free‐Living Raptorial Birds in Central Spain

A total of 595 faecal samples from raptorial birds, either captive or free‐living, residing in GREFA Wildlife Hospital were bacteriologically examined using various selective media and an Automated Diagnostic Assay System for Salmonella detection. Serotype and phage type of the strains identified as Salmonella was determined. In the captive group, of the 285 samples examined, 21 (7.36%) were positive for Salmonella. Serotyping revealed that most of the individuals were infected by Salmonella serotype Havana. This result suggested that there could be a source of contamination in the Hospital although it could not be established. In the wild free‐living group, over 310 samples examined (4.19%) were positive for Salmonella. The Salmonella isolates showed a major variety of serotypes: Enteritidis, Adelaide, Brandenburg, Newport, Typhimurium, Hadar, Saintpaul and Virchow. Most of them are similar to those commonly described in isolates from human and domestic animals. These results indicate that wild birds could be involved in the dissemination of Salmonella in humans or domestic animals or vice versa.  相似文献

鸭疫里氏杆菌各血清型在我国的分布   总被引：3，自引：1，他引：2  

吕殿红 《广东畜牧兽医科技》2003,28(5):18-20

鸭疫里氏杆菌病(Riemerella anatipestifersis,RA)是家鸭、火鸡、鹅和多种其它鸟类的一种接触性传染病,能引起1～8周龄的鸭发生浆膜炎、心包炎、气囊炎和肝周炎等为特征的急性败血性传染病。我国近年来对该病病原的分离及其血清型的鉴定等方面进行了较多的研究,目前已证实我国有1、2、3、4、5、6、7、8、10、11、13、14、15、17等14种血清型的RA,另新发现4种新血清型(22、23、24、25型),多种血清型的存在是造成该病防制困难的重要原因。本文介绍了我国对RA血清型的研究,及各血清型在我国的分布,以期对综合防制该病有一定的启发和指导。  相似文献
