ЯКИМЕНКО Н.И., КЛЕТИКОВА Л.В. Ивановская государственная сельскохозяйственная академия Аннотация: У павлина обыкновенного (Pavo cristatus), перенесшего сильный стресс из-за нападения и повреждений, нанесенных собакой, спустя год обнаружилась хромота. При осмотре костно-хрящевые экзостозы отсутствовали, на подошвах тазовых конечностей отмечены незначительные припухлости. В каловых массах обнаружено большое количество включений кремового цвета, содержание мочевой кислоты в сыворотке крови составило 1027 мкмоль/л. Лечение включало коррекцию рациона, поение бутилированной водой, включение в питьевой режим минеральной щелочной воды и отвара льняного семени, обогащение рациона ретинолом; из медикаментозных средств назначены 0,25% раствор гексаметилентетрамина и аллопуринол. На фоне улучшения состояния птицы ее лечение было прекращено владельцем. После лечения для кормления был использован комбикорм, поение - в летне-осеннее время водопроводной водой, в зимнее - снегом, что привело к гибели птицы. При вскрытии на внутренних органах выявлены вкрапления и наложения беловато-желтоватой массы различного диаметра. На петле тощей кишки обнаружен узел округлой формы, 2,5 см в диаметре, упругой консистенции, заполненный творожистой массой желтого цвета. Также отмечены дистрофия миокарда, расширение левой половины сердца. При морфологическом исследовании установлено, что узел инкапсулирован в подслизистом слое стенки кишки. В зонах некроза узла выявлены волокнистые некротизированные структуры и капли жира, в окружающем гистиоцитарном инфильтрате крупные капли белкового субстрата розового цвета, что связано с нарушением белково-жирового обмена типа tophi urici у млекопитающих. Таким образом, стресс, обусловленной травмой, привел к нарушению у павлина обмена веществ, миокардиодистрофии и развитию подагры, приведших к летальному исходу.

The epidemiology of avian influenza is unknown in Cameroon despite the two outbreaks that occurred in 2006 and 2016-2017, respectively. In order to fill the gap, an attempt was made to provide some basic information on the epidemiology of highly pathogenic avian influenza in Cameroon. Thus, data were collected from follow-up reports of the second HPAI outbreaks prepared by the veterinary health officials of Cameroon and sent to the World Organisation for Animal Health (OIE). Two HPAI virus strains (H5N1 and H5N8) turned out to occur, with H5N1 virus involved in the Center, South, West, and Adamawa regions outbreaks and H5N8 involved in the Far North outbreak only. The affected hosts were the laying hens, backyard chickens, turkeys, guinea fowls, ducks, broiler and layer breeders, and geese for the H5N1 virus and the Indian peafowl (Pavo cristatus), pigeon, ducks, backyard chickens, and guinea fowls for the H5N8 virus. The first outbreak took place in Mvog-Betsi poultry complex in the Center region on the 20th May 2016 and spread to other regions. The mortality rate varied from 8% to 72% for H5N1 virus and was 96.26% for the H5N8 strain in Indian peafowl. No human case was recorded. The potential supporting factors for disease dissemination identified on the field were the following: poultry and eggs dealers moving from one farm, market, or town to another without any preventive care; poor biosecurity measures on farms and live poultry markets. After the first HPAI H5N1 virus outbreak in 2006, the second HPAI outbreak ten years later (2016-2017) involving two virus strains is a cause of concern for the poultry industry. The Cameroon Epidemio-Surveillance Network needs to be more watchful.

Reflectance Measurements

The blue neck and breast feathers of the peacock are structurally coloured due to an intricate photonic crystal structure in the barbules consisting of a two-dimensionally ordered rectangular lattice of melanosomes (melanin rodlets) and air channels embedded in a keratin matrix. We here investigate the feather coloration by performing microspectrophotometry, imaging scatterometry and angle-dependent reflectance measurements. Using previously determined wavelength-dependent refractive indices of melanin and keratin, we interpret the spectral and spatial reflection characteristics by comparing the measured spectra to calculated spectra by effective-medium multilayer and full three-dimensional finite-difference time-domain modelling. Both modelling methods yield similar reflectance spectra indicating that simple multilayer modelling is adequate for a direct understanding of the brilliant coloration of peacock feathers.

Tari Merak Jawa Barat, merupakan jenis tarian tontonan (pertunjukan). Tari Merak pertama kali diciptakan oleh Rd. Tjetje Somantri pada tahun 1955. Kemudian pada tahun 1965, tari Merak dikemas kembali oleh Irawati Durban Ardjo, yang bertujuan untuk dipertunjukkan pada misi kesenian Soekarno. Tari Merak yang sering kita jumpai saat ini merupakan Tari Merak karya Irawati Durban Ardjo.Tarian ini mempresentasikan keindahan yang dimiliki oleh burung merak pada saat burung merak jantan melebarkan ekornya. Kebanyakan masyarakat Indonesia salah berasumsi jika tarian ini bercerita tentang kehidupan burung merak betina, sedangkan sang jantanlah yang memamerkan keindahan bulu ekornya. Sang jantan melakukan gerak-gerik yang tampak seperti tarian gemulai untuk menunjukkan pesona dirinya, sehingga sang betina terpesona dan bersedia kawin dengannya. Gerakan itulah yang mengekspresikan dibuatnya Tari Merak. Untuk mendukung keindahan tari, maka dibuat bentuk visual Merak pada kostum Tari Merak yang telah diinovasikan oleh Irawati. Irawati mengonsepnya melalui ide-ide kreatif dan mengindahkan esensi burung merak pada bentuk visual. Beberapa bagian kostum tari Merak Irawati, yaitu siger (mahkota), susumping, giwang (anting), kelat bahu, garuda mungkur, gelang tangan, kemben, ekor, Ikat pinggang, kacih, selendang, dan sinjang. Kostum yang memiliki banyak unsur estetika seperti garis (lurus, lengkung, bergelombang), bentuk (lingkaran, setengah lingkaran, persegi panjang, ekor merak, dan penyederhanaan burung merak), ornamen (ragam hias binatang, ragam hias tumbuhan, geometris, ulir). Beberapa motif yang digunakan yaitu motif ekor, bulu, ataupun keseluruhan bentuk burung merak. ABSTRACT Peacock Dance is a type of spectacle dance (performance). The Peacock Dance was first created by Rd. Tjetje Somantri in 1955. Then in 1965, the Merak dance was repackaged by Irawati Durban Ardjo, which aimed to be performed on Soekarno's art mission. The Peacock Dance that we often encounter at the moment is the Peacock Dance by Irawati Durban Ardjo. This dance presents the beauty of peacocks. The peacock is the inspiration for the creation of the Peacock dance and its beauty is found when the male peacock widens its tail. Most Indonesian people wrongly assume that this dance tells the story of the life of a female peacock, while the male exhibits the beauty of its tail feathers. The male performs movements that look like graceful dances to show his charms so that the female is fascinated and willing to marry him. That movement expresses the Peacock Dance. With the visual form of the Peacock Dance costume that has been innovated by Irawati. Irawati conceptualized it through creative ideas and heeded the essence of the peacock in visual form. Some parts of the Merraw Irawati dance costume, namely siger (crown), susumping, ear studs (earrings), kelat shoulders, garuda mungkur, wristbands, kemben, tail, belt, belts, shawls, and sinjang. Costumes that have many aesthetic elements such as lines (straight, curved, wavy), shapes (circles, semicircles, rectangles, peacock tails, and simplifications of peacocks), ornaments (various animal decoration, plant decoration, geometric, threaded). Some of the motifs used are the tail, feather, or overall shape motif.
