Immune-mediated haemolytic anaemia in 110 dogs in Victoria, Australia

Objective   Evaluate the survival and prognostic indicators (i.e. breed predilection, season, blood transfusion, and the prevalence of autoagglutination) of dogs with immune-mediated haemolytic anaemia (IMHA) in Victoria, Australia.
Design   Retrospective study of 110 diagnosed with primary IMHA at the University of Melbourne Veterinary Clinic and Hospital.
Results   In total, 80 of the dogs (72.7%) were discharged from hospital and 48 of 65 (73.8%) dogs available for follow-up were known to be alive at 1 year, giving an overall 1-year survival of 48 (50.5%) of 95 dogs for which survival data were available. Regarding breed, 80 (18.2%) of the 110 dogs were Maltese-breed dogs compared with 81 (7.4%) of 1100 control dogs (P < 0.001). Springer Spaniels (P = 0.02), Hungarian Vizslas (P = 0.02) and Airedale Terriers (P < 0.001) were also over-represented compared with the control sample. There was no evidence of an association between the occurrence of IMHA in dogs and season in this study. Receiving one or more blood transfusions did not affect survival to the time of discharge from hospital. On initial blood smear examination, 57 (51.8%) of the 110 dogs had spontaneous autoagglutination and its presence was associated with decreased survival to discharge from hospital (P = 0.03). Packed cell volume, white cell count, platelet count and serum total bilirubin on admission had no effect on survival to the time of discharge from hospital or 1 year later.
Conclusion   Dogs with IMHA have a guarded prognosis as only half are still alive 1 year after the acute event.     

牧草如何生长--植物生长与放牧管理之关联

适当管理饲料饲草资源的基本原则是理解多年生牧草如何生长.长期以来,对根系生长有了基本的了解,对去叶和环境对根系生长的影响也知之甚多.然而,对去叶、干旱及其他环境因素对多年生牧草的影响以及这些牧草对去叶的反应缺乏应有的理解.从牧草返青到开花,植物处于短枝阶段,适度放牧并不对多年生牧草的健康和活力造成危害,因为植物会弥补其失去的叶片.然而,当牧草从短枝向长枝阶段(节间伸长和开花期)转移时,碳水化合物主要用于节间伸长和开花过程.在开花后和休眠前期,碳水化合物主要向茎基和植物基部转移,以供来年新枝条的发育.因此,在花后和休眠前期,放牧系统必须被调节到"无放牧"状态."无放牧"状态,如休息、轮牧、延迟轮牧和快速轮牧制,其价值在于这种定期的禁牧可提高多年生牧草的活力,改善草地的健康状况,并且在不利的环境条件下,保证在植物去叶后的后续生产能力.
