Avian Reproductive Tract Surgery: From Egg Binding to Neoplasia
MVDr Andrea Henrik presented this distance-learning event for the Atlantic Veterinary College Zoological and Laboratory Animal Medicine Club. This Lunch & Learn presentation was co-hosted by the Lafeber Company Student Program and the Association of Avian Veterinarians Student Committee.
Raptor Gastrointestinal Anatomy and Physiology
Raptors are a diverse group of birds consisting of three taxonomic orders: Strigiformes (owls), Falconiformes (falcons and caracaras), and Accipitriformes (hawks, eagles, and remaining families). Although the normal diet of free-living raptors varies considerably among species, all raptors hunt and feed on other animals. Meat and fish-eaters possess unique gastrointestinal characteristics that reflect their predatory lifestyle. This review article begins with unique features of the bill and oropharynx, then describes distinctive features of gastrointestinal tract before concluding with pellet formation and egestion and digestive strategies.
Passerine Anatomy & Physiology Basics
Perching birds or songbirds belong to order Passeriformes, which makes up the largest taxonomic group of birds. Passeriforms make up nearly 60% of all birds with over 5,000 species belonging to this group. If you are comfortable with psittacine anatomy and physiology, then you are well on your way to understanding passerines. LafeberVet has listed ten interesting, clinically significant facts about passerine anatomy and physiology…
Avian Anatomy and Physiology Basics
This article is the focus of LafeberVet’s Avian Anatomy Teaching Module, which is RACE-approved for 1 hour of continuing education credit. This review begins with a brief summary of Class Aves before exploring various organ systems. Important vocabulary terms and key concepts are emphasized throughout the text. The reader should have a basic understanding of mammalian anatomy. Birds are quite different both structurally and functionally when compared to mammals, therefore comparisons are frequently drawn between these two taxonomic groups. Since form follows function, descriptions of avian anatomy will also merge into physiology and other life sciences, where appropriate. Clinically relevant information and additional resources on LafeberVet are also highlighted.
The Use of GnRH Agonists in Avian Practice
Avian veterinarian Brian Speer presented this live webinar, RACE-approved for 1.5 credit hours. Reproductive activities, particularly those that are recurrent, pose a significant threat to the health and behavioral well-being of many pet birds. This presentation began by reviewing the basics of female reproductive anatomy and endocrinology before discussing the role of environmental and behavioral stimuli on reproductive endocrinology. Dr. Speer then presented an ethical scale for selecting and prioritizing recommendations for intervention, before discussing medical therapy as well as the environmental and behavioral interventions that can be employed. Dr. Speer concluded with a discussion of behavioral science and its applications to the management of hormonal problems.
A Necropsy Guide to Serpentes
The postmortem exam is a key diagnostic tool in understanding the reasons for a snake’s morbidity and mortality. Necropsies can provide valuable information to provide a risk assessment for other animals in a population or collection and can help provide closure for a grieving owner. This manuscript reviews the snake necropsy in a systemic, thorough manner, describing normal anatomy and proper collection technique from head to tail.
A Guide to Avian Necropsy
The postmortem examination is a valuable part of the diagnostic work-up. Shared by a veterinary pathologist with a special interest in birds, this guide to avian necropsy provides comprehensive instructions for the avian postmortem exam. This article offers step-by-step guidance on avian necropsy with a variety of photographs and video clips that illustrate useful clinical techniques and normal avian anatomy. Feel confident in your knowledge of avian anatomy? You can also “Test Yourself” by identifying the structures shown in four separate images.
Reproductive Disease in Reptiles
Reptile reproduction can be a confusing topic due to the variety of normal reproductive strategies found throughout different reptile species. Nevertheless it important to understand normal reproductive processes to correctly approach some commonly seen problems. This webinar recording reviews normal reproductive strategies of reptiles, including important reproductive anatomy and physiology. Three clinically important conditions, pre-ovulatory or follicular stasis, post-ovulatory dystocia, and cloacal prolapse, are also explored in detail.
Anatomy and Physiology of the Avian Gastrointestinal Tract: Clinical Applications
As a part of the Encore ICARE 2015 Lafeber Symposium Lecture Series, Dr. Susan Orosz provided an introductory presentation on anatomy and physiology of the avian gastrointestinal tract. View a recording of this webinar today.
Sea Turtle Physical Examination: Part 2
Part of a unique series on sea turtle veterinary medicine and wildlife rehabilitation, this article explores many components of the sea turtle physical exam. Evaluation of the shell is discussed in both cheloniids and leatherbacks (Dermochelys coriacea) as well as assessment of the cardiopulomonary system, skin, long bones and joints, cloaca and tail. Evaluation of the coelom by inguinal palpation is described as well as measurement of body temperature. Specialized testing such as neurologic and in-water examinations are also described. Common physical examination findings like fibropapillomas in green turtles (Chelonia mydas) and epibiota in loggerhead turtles (Caretta caretta) are also discussed. LOGIN to view references.
Five Features of Marsupial Anatomy: With Focus on the Sugar Glider Physical Exam
Free-ranging sugar gliders live in the treetops and glide from tree to tree using their patagium like a kite and their tail as a rudder to control the direction of flight. The patagium is a furred membrane of skin or gliding membrane that stretches between the forelimbs and hind legs. These skin folds are extensions of the lateral body wall. When the glider is at rest, this excess skin appears as a rippled border along the sides. During a glide, the skin spreads out to form a rectangle…
Presenting problem: Prolapse in Reptiles
Prolapse in reptiles can involve the cloaca, a common receiving chamber for the reproductive, urinary, and gastrointestinal tracts. Prolapses can also originate from the distal gastrointestinal tract, reproductive organ, or urinary bladder—in those species with a bladder like the green iguana and leopard gecko…
Administration of Medication in Reptiles
Reptile owners are routinely instructed on oral or intramuscular drug administration techniques for outpatient care. In many instances and in many species, parenteral injections are preferred over the oral route. Injectable medications can be delivered intramuscularly, subcutaneously, intracoelomically, intravenously, or…
Basic Cytology of the Avian Gastrointestinal Tract
Historically, routine Gram’s stains were performed in apparently healthy birds. As our understanding of avian medicine has grown, avian veterinarians have questioned the reliability and validity of Gram’s stain cytology as a screening test. Cytology is indicated when specific problems are reported during a detailed medical history or when…
