欧普迪肯肉鸡、饲料自动计量系统

第一部分 肉鸡称重的仪器和方法比较 有人说肉鸡称重单纯是为了满足加工商的需要,不是的.在称重时,需要将肉鸡按照预定的时间放进某个环境内进行称重,这种环境是让称重者能够尽可能精确地进行称重.在鸡场,称重能满足许多方面的需要.     

"遭遇"藏獒

你见过草原上乱窜的旱獭、天空中翱翔的兔鹰、成千上万迁徒的羊群和牦牛吗？如果这些还难不倒你,那我还有一招：你和凶猛异常的藏獒面对面过吗？今夏,我到甘肃南部藏区就实实在在“遭遇”了一回。     

“Cochin”起源于中国

前言　　我国古代岭南交趾鸡，其后代应是当今岭南 (广东、广西、海南 )饲养的麻鸡、麻黄鸡、麻黑鸡，特别是近似岭南原鸡亚种、海南亚种的鸡为正统。麻鸡、麻黄鸡、麻黑鸡早已广泛扩散到长江、黄河流域。早在公元前秦汉纪，岭南交趾鸡就已沿着“海上丝绸之路”远渡重洋到欧洲，繁衍后代，开创了欧洲养鸡的历史。英文“ Cock、 hen、 chick、 chicken”等等鸡的系列英文名词。　　浏览《中国养禽史》，即发现 150年前开放“五口通商”时，上海鸡首次输往英国，却引起中英专家争议之案，至今尚未平息。在审理中，也牵涉欧洲鸡种源的千古之谜…     

“阿狼”的狗

<正>在那场撕心裂肺的汶川大地震后,有8位生还者仅靠5千克大米和一头名叫"阿狼"的狗,在四川绵竹荒凉的大山里艰难地坚持了17天,成为那场灾难的获救者。回忆起那段地狱般的日子,那群生死相依的8位兄弟和那头名叫"阿狼"的狗,都将成为他们一生中挥之不去的记忆。

一次"救狗行动"引发的大争论

阅读提示:近日,进行了一场民间"救狗行动"。从普通民众到公众人物,都对此次"救狗行动"表现出空前的热情:捐款赎狗、高速截车救狗……然而就是这样的救狗志愿行动,十几个小时的解救过程,却陷入了合情、合理、不合法的尴尬境地。同时,救狗一事,在网上引起了广泛热议,不少网友情绪激昂地提出种种质疑和批判。

饲料企业财务工作应从"善后"转向"谋前"

财务工作对于企业至关重要,会计和财务工作联系着企业经营和管理的各个方面,有效地整合着企业的价值体系,使企业目标和战略通过价值链的方式予以确定。对饲料企业的经营管理来说,销售管理是龙头,生产管理是基础,财务管理是核心。我国饲料企业普遍重视销售工作,但对财务工作不够     

Tail-base mass from a "horse of a different color"

A 14-year-old bay Thoroughbred gelding was presented for evaluation of a mass at the base of the tail. The mass had been present for 1 year, and recently had begun to increase in size. Additional masses were found around the eye and shoulder. A fine-needle aspirate of the tail-base mass revealed highly anaplastic round to polyhedral cells containing dark green to black cytoplasmic granules interpreted to be melanin. Histologically, the mass was composed of pleomorphic, poorly pigmented, round to polyhedral cells interpreted to be neoplastic melanocytes. With immunohistochemistry, the cells were positive for vimentin and S-100, but negative for pancytokeratin and Melan-A. The cytologic and histopathologic diagnoses were amelanotic melanoma. The horse was treated with cimetidine, but the tumor continued to progress. In this report, we describe the cytopathologic features of an aggressive amelanotic melanoma in a non-grey horse and emphasize the unique correlation between cytologic and histologic findings.

Molecular characterization of a myosin alkali light chain-like protein, a "concealed" antigen from the hard tick Haemaphysalis qinghaiensis

There should be some differences between antibodies generated by feeding ticks on animals and those derived by immunizing animals with tick extracts. Here, we found serum collected from sheep immunized with Haemaphysalis qinghaiensis salivary gland extracts could detect two more protein bands with molecular weights of 22 and 37 kDa (P22 and P37) on Western blots of extracts of tick salivary glands than serum from tick infected animals. Rabbit anti-H. qinghaiensis differential protein immune serum was then generated from P22 and P37 and was used to immunoscreen a cDNA library constructed from salivary glands, Malpighian tubules and ovaries of partially engorged H. qinghaiensis. A cDNA contains an open reading frame of 483 bp that codes for 160 amino acid residues with a coding capacity of 18 kDa was cloned and designated Hq02. Expression analysis by RT-PCR showed that this gene is expressed in salivary glands, midguts, other organs and different developmental stages of H. qinghaiensis. The predicted amino acid sequence of the Hq02 gene had high homology to some known myosin alkali light chain (MLC) proteins. A fusion protein consisting of 130 amino acids of Hq02 protein and 335 amino acids of T7 gene 10 protein was expressed in Escherichia coli and used to immunize sheep. Western blot showed that only rabbit anti-H. qinghaiensis differential protein immune serum could recognize the expressed Hq02 protein, while rabbit anti-H. qinghaiensis saliva immune could not. This proved Hq02 protein was a "concealed" antigen. Immunization with the recombinant Hq02 conferred a 21.8% reduction of engorgement weight for adult female ticks that fed on the immunized sheep. This is the first report of tick myosin alkali light chain and the function of this protein is discussed.     

"If it's tuesday, I must be the student": lessons learned from the other side of the classroom

After teaching veterinary students for over 10 years, the author returned to graduate school as a part-time doctoral student in educational administration and policy studies. Sitting in the student's chair brought back an acute awareness of the submissive position of the student, the daunting prospects of navigating a university system, and the challenges of managing the workload of a degree program. The experience also provided a fresh perspective on instruction, including course delivery, effective use of class time, and the potential impact of the language one uses with students. These insights on teaching and learning and on the student's viewpoint may help educators become more empathetic and effective instructors and mentors of veterinary students.
