肉禽饲养密度应激及营养调控研究进展

饲养密度是家禽饲养管理中的一个重要因素。提高饲养密度虽然可以降低饲养成本,但高密度可能引起家禽发生氧化应激,损害家禽健康、生产性能和肉品质。文章综述了提高饲养密度导致的肉禽生产性能、胴体品质、免疫机能等的影响及机制,并从日粮营养素、功能性氨基酸、有益微生物角度综述了现代营养技术措施调控肉禽饲养密度应激的研究进展。

A Comparison of Xylazine–Diazepam–Ketamine and Xylazine–Guaifenesin–Ketamine in Equine Anesthesia

After sedation with xylazine (0.3 mg/kg intravenously [IV]), anesthesia was induced in six healthy horses with ketamine (2.0 mg/kg IV) and guaifenesin (100 mg/kg IV), diazepam (0.05 mg/kg IV), or diazepam (0.10 mg/kg IV). Anesthesia was maintained with halothane for 30 minutes. Heart rate, respiratory rate, direct arterial blood pressure, arterial blood gas, and pH measurements were made before, and at set intervals after, induction of anesthesia. Quality and characteristics of induction and recovery were evaluated objectively by an independent observer unaware of the protocol used. There were no significant differences among the three protocols from pre-induction values for arterial blood pressure, blood gas values, and pH. There was significantly greater ataxia at induction with the use of guaifenesin. The nature of induction, transition to and recovery from general anesthesia were comparable between guaifenesin and the higher dose of diazepam. Because of movements and difficulty with intubation, the lower dose of diazepam was considered unsatisfactory. It was concluded that diazepam (0.10 mg/kg) could be substituted for guaifenesin (100 mg/kg) to produce comparable quality of anesthesia in horses.

Baylisascariosis—Infections of animals and humans with ‘unusual’ roundworms

The nematode genus Baylisascaris (order Ascaridida, superfamily Ascaridoidea) contains nine relatively host-specific, parasite species of carnivores, omnivores, herbivores, carnivorous marsupials or rodents. They have a facultative heteroxenous life cycle, at least under experimental conditions. Eggs passed in faeces embryonate in the environment and the second-stage larva infective for both definitive and intermediate hosts develops. In intermediate hosts larvae migrate extensively through tissues, where they grow and moult to the third-stage, causing extensive damage. All Baylisascaris spp. are considered a potential cause of visceral, ocular and/or neural larval migrans in mammals including humans and in birds. This paper summarises our current knowledge on the prevalence, biology, pathogenicity and zoonotic significance of three Baylisascaris species: B. transfuga, B. schroederi and B. procyonis which have as definitive hosts bears, giant pandas and raccoons (occasionally dogs), respectively.     

State‐of‐the‐Art‐Review: Immunomodulatory effects of opioids

Objective – To review the immunomodulatory effects of opioids. Data Sources – Original research publications and review articles using the PubMed search engine with the following keywords – opioids, morphine, immuomodulation, and immunosuppression. Veterinary and Human Data Synthesis – Opioids have been shown to modulate the immune system in animal models by affecting both the acquired and innate arms of the immune system. Natural killer cell activity, T‐cell proliferation, antibody production, phagocytic cell function, and cytokine production have all been shown to be affected by opioids. Many of these effects are reversed by opioid antagonists. Opioids have also been shown to induce sepsis in laboratory animals. Opioid administration alters immune parameters in healthy humans at analgesic doses and may increase the risk of infection in some patient populations. Conclusions – While opioids remain the most powerful and widely used analgesics available, their negative effects on the immune system are well established in the laboratory setting. Thoughtful consideration should be given to the use of certain opioids in critically ill patients, especially those with pre‐existing immunocompromise.     

四川地区区域性果树的园林观赏性综合评价

对四川地区10种区域性果树进行了观赏性的综合评价,以期为其在园林绿化中的应用提供参考资料。采用灰度关联分析法,选择了花量与花色、花期、果形与果色、挂果期、株形和株高6个指标,对四川地区10种区域性果树的园林观赏性进行综合评价。结果表明,石榴的观赏性与理想果树最接近。其次是荔枝、脆红李、甜樱桃、水蜜桃、柠檬、苹果、雷波脐橙、五星枇杷和红心猕猴桃,其中五星枇杷（γ5=0.5960）和红心猕猴桃的观赏性较差（γ6=0.5715）。石榴、荔枝、脆红李、甜樱桃和水蜜桃的观赏性较好,可广泛的应用于园林绿化。
