Antibiotic responsive ulcerative dermatoses in German Shepherd Dogs with mucocutaneous pyoderma     

Bassett RJ  Burton GG  Robson DC 《Australian veterinary journal》2004,82(8):485-489

Mucocutaneous pyoderma is a disease of unknown aetiology affecting mucocutaneous skin and is responsive to antibacterial therapy. It is reported to affect the lips, nasal planum, nares, perioral skin and less commonly, the eyelids, vulva, prepuce and anus. Three cases of mucocutaneous pyoderma are presented. Two of the cases showed ulcerative lesions in the inguinal and axillary regions in addition to more typically reported lesions. Two of the dogs had concurrent atopic dermatitis and the third had clinical signs suggestive of hyper-sensitivity disease. The clinical and histopathological features, differentiation of mucocutaneous pyoderma from discoid lupus erythematosus, and long-term management of mucocutaneous pyoderma are discussed.  相似文献

Lechiguana (Focal Proliferative Fibrogranulomatous Panniculitis) in Cattle     

Riet-Correa F  Ladeira SL  Andrade GB  Carter GR 《Veterinary research communications》2000,24(8):557-572

Lechiguana is a disease of cattle characterized by large, hard, subcutaneous swellings that grow rapidly and result in death after 3–11 months in untreated animals. Cattle treated with antibiotics recover. The disease has been reported from five states in south and southeastern Brazil. Histologically, the lesion consists of focal proliferation of fibrous tissue infiltrated by plasma cells, eosinophils, lymphocytes and sometimes neutrophils. The primary lesion is an eosinophilic lymphangitis, which results in eosinophilic abscesses, with occasional rosettes containing bacteria in their centres. Much experimental and epidemiological evidence, reviewed in this article, supports the suggestion that lechiguana is caused by an association of Pasteurella granulomatis (syn: Mannheimia granulomatis) and Dermatobia hominis.  相似文献   

Estimation of feed intake and apparent digestibility of equines and cattle grazing on heathland vegetation communities using the n-alkane markers     

L.M.M. Ferreira  U. Garcia  M.A.M. Rodrigues  R. Celaya  A. Dias-da-Silva  K. Osoro 《Livestock Science》2007,110(1-2):46-56

The application of n-alkanes as faecal markers to estimate feed intake and apparent digestibility (DMD_ap) of equines and cattle was studied. Additionally, the effect of using different data on diet composition, known proportions of the diet components (DC1) and those estimated using the alkane markers (DC2), on the accuracy of intake and DMD_ap estimates was evaluated. Six mature horses, divided in two groups of three animals (H1 and H2), and three adult non-lactating cows of Asturiana de los Valles breed (C) were housed in individual stalls. H1 and C groups were fed on a diet composed of Lolium perenne L. (70%) and heather (30%) and H2 received L. perenne (40%), heather (30%) and Ulex gallii Planchon (30%). The dietary component heather represented the field proportions of different plant species of heathland, namely Erica umbellata L., Erica cinerea L. and Calluna vulgaris L., at this experimental period. All animals received a daily dose of paper pellets containing C₂₄, C₃₂ and C₃₆ n-alkanes as external markers with the purpose of using different n-alkane pairs of adjacent chain length for feed intake estimations. The results indicated that a period of 3 and 5 days was sufficient for these external markers to reach a steady concentration in faeces of cattle and equines, respectively. In contrast to the results obtained in cattle, the alkane faecal recovery in equines was unrelated to the carbon chain length. Diet composition only affected the faecal recovery of the alkanes C₂₄ (P < 0.05), C₃₁ (P < 0.05), C₃₂ (P < 0.05) and C₃₆ (P < 0.01) in the faeces of the equines, suggesting a different dispersion of the synthetic n-alkanes in the digesta. In equines, DMD_ap estimates were not affected by the n-alkane (C₂₇, C₂₉, C₃₁ and C₃₃) used in the calculations, contrasting with the significant (P < 0.001) effect observed in cattle. In both animal species, the data on diet composition (DC1 or DC2) used in the calculations did not affect DMD_ap estimates. Feed intake estimates were affected by the alkane pair used in the calculations in H1 (P < 0.05), H2 (P < 0.001) and C (P < 0.001). The data on diet composition used in the intake calculations affected the resultant estimates in H1 (P < 0.05) but not in H2 and C. The differences from the known intake values were lower when using C₃₁:C₃₂ alkane pair, overestimating intake in only an average of 4.5, 13.0 and 1.3% in H1, H2 and C, respectively, using DC1 or DC2. The results obtained in this study confirm the accuracy of the n-alkane markers to estimate simultaneously feed intake, apparent digestibility and diet composition of equines and cattle grazing these type vegetation communities.  相似文献   

Validation of the 9-11th rib cut to estimate the chemical composition of the dressed carcass and of the whole empty body of Zebu cattle     

Pedro Veiga Rodrigues Paulino  Marcos Antônio Lana Costa  Mário Fonseca Paulino  Karla Alves Magalhães  Edenio Detmann  Rilene Ferreira Diniz Valadares  Marlos Oliveira Porto  Kamila Andreatta 《Livestock Production Science》2005,93(3):245-253

This study was conducted to validate the 9-11th rib cut to estimate the chemical composition of the carcass and of the empty body weight (EBW) of Zebu cattle. Nineteen Zebu steers with initial body weight of 266.5±32.2 kg were used. Four steers were slaughtered at the beginning to compose the reference group; three were fed at maintenance level, and the remaining were allotted to different planes of nutrition (5.0%, 35.0% and 65.0% concentrate levels in the diets, DM basis). The 9-11th rib cuts and half of the carcasses were dissected and the weights of fat, muscle and bone tissue were recorded. The components fat, muscle and bone tissue from the 9-11th rib cut and from the half carcass were sampled and chemical analysis of fat, protein, water, ash and minerals determined. The 9-11th rib cut satisfactorily estimated the physical composition of the carcass, but not the chemical composition. The 9-11th rib cut appropriately estimated the chemical composition of the carcass in terms of protein, water, ash and macro mineral content. For the percentage of fat and Ca, an over- and underestimation of 7.84% and 13.34%, respectively, were detected. Regression equations were fitted to estimate the percentage of fat and Ca in the carcass, and that of protein, water and ash in the whole empty body.  相似文献   

Recent Trends in Weed Control in Freshwater¹⁾     

T.O. Robson 《EPPO Bulletin》1973,3(3):5-15

While in many situations, such as irrigation and drainage ditches, the unobstructed movement of water is paramount and complete control of the weeds is needed, most freshwater nowadays has many functions some of which involve biological systems in which weeds play an important part. Trends in the development of new weed control techniques aimed at replacing traditional hand cutting methods while maintaining the required condition of the water are briefly reviewed. These include mechanical, chemical and biological methods all of which contain potentially valuable tools for the management of freshwater ecosystems.  相似文献
