  • Avian Crop Function–A Review
    Ann. Anim. Sci., Vol. 16, No. 3 (2016) 653–678 DOI: 10.1515/aoas-2016-0032 AVIAN CROP function – A REVIEW* * Bartosz Kierończyk1, Mateusz Rawski1, Jakub Długosz1, Sylwester Świątkiewicz2, Damian Józefiak1♦ 1Department of Animal Nutrition and Feed Management, Poznań University of Life Sciences, Wołyńska 33, 60-637 Poznań, Poland 2Department of Animal Nutrition and Feed Science, National Research Institute of Animal Production, 32-083 Balice n. Kraków, Poland ♦Corresponding author: [email protected] Abstract The aim of this review is to present and discuss the anatomy and physiology of crop in different avian species. The avian crop (ingluvies) present in most omnivorous and herbivorous bird spe- cies, plays a major role in feed storage and moistening, as well as functional barrier for pathogens through decreasing pH value by microbial fermentation. Moreover, recent data suggest that this gastrointestinal tract segment may play an important role in the regulation of the innate immune system of birds. In some avian species ingluvies secretes “crop milk” which provides high nutri- ents and energy content for nestlings growth. The crop has a crucial role in enhancing exogenous enzymes efficiency (for instance phytase and microbial amylase,β -glucanase), as well as the activ- ity of bacteriocins. Thus, ingluvies may have a significant impact on bird performance and health status during all stages of rearing. Efficient use of the crop in case of digesta retention time is es- sential for birds’ growth performance. Thus, a functionality of the crop is dependent on a number of factors, including age, dietary factors, infections as well as flock management.

  • Raptor Digestion Facts
    Raptor Digestion Facts For birds that have a crop, food passes to the crop to soften or to just be stored temporarily. From there food goes to the stomachs. Owls do not have crops, all other raptors do. Food is stored in the crop on the way down, but not on the way up. Birds have two stomachs (in this order): A glandular stomach (the proventriculus) which digests food chemically A muscular stomach or gizzard (the ventriculus) that grinds food with the aid or grit. In many carnivorous species – hawks, for example, their glandular stomach is so highly acidic, it dissolves bones. The bearded vulture of Europe and China is said to have a stomach so acidic it can dissolve the whole of a cow’s vertebra in one or two days. Pellets are formed in the gizzard. A given bird’s pellet will be the size and shape of their gizzard. The gizzard of birds serves the same function as the teeth and strong jaws of mammals. The gizzard is most developed in birds that eat plant parts. Birds intentionally ingest grit to be kept in their gizzard to help grind food. They can prevent this grit from passing through the digestive system with the food, and remain in the gizzard. Birds prefer brightly colored grit. Such examples of grit found in birds include: quartz, granite, ruby, gold, fruit pits, coal, ground oyster shells, black lava, and lead shot form shotguns (this of course causes lead poisoning, which we do see a lot of at Willowbrook). Many other birds cough-up pellets, especially those which feed much on insects.

  • Lab #23 Anal Triangle
    THE BONY PELVIS AND ANAL TRIANGLE (Grant's Dissector [16th Ed.] pp. 141-145) TODAY’S GOALS: 1. Identify relevant bony features/landmarks on skeletal materials or pelvic models. 2. Identify the sacrotuberous and sacrospinous ligaments. 3. Describe the organization and divisions of the perineum into two triangles: anal triangle and urogenital triangle 4. Dissect the ischiorectal (ischioanal) fossa and define its boundaries. 5. Identify the inferior rectal nerve and artery, the pudendal (Alcock’s) canal and the external anal sphincter. DISSECTION NOTES: The perineum is the diamond-shaped area between the upper thighs and below the inferior pelvic aperture and pelvic diaphragm. It is divided anatomically into 2 triangles: the anal triangle and the urogenital (UG) triangle (Dissector p. 142, Fig. 5.2). The anal triangle is bounded by the tip of the coccyx, sacrotuberous ligaments, and a line connecting the right and left ischial tuberosities. It contains the anal canal, which pierced the levator ani muscle portion of the pelvic diaphragm. The urogenital triangle is bounded by the ischiopubic rami to the inferior surface of the pubic symphysis and a line connecting the right and left ischial tuberosities. This triangular space contains the urogenital (UG) diaphragm that transmits the urethra (in male) and urethra and vagina (in female). A. Anal Triangle Turn the cadaver into the prone position. Make skin incisions as on page 144, Fig. 5.4 of the Dissector. Reflect skin and superficial fascia of the gluteal region in one flap to expose the large gluteus maximus muscle. This muscle has proximal attachments to the posteromedial surface of the ilium, posterior surfaces of the sacrum and coccyx, and the sacrotuberous ligament.

  • Crop Problems
    Text and photos: Monique de Vrijer Translation: Diana Hedrick CROP PROBLEMS The crop serves as a temporary ‘storage bin’ for the feed the chicken eats. It is often full during and at the end of the day and should normally be empty when the bird starts its day in the morning. Unfortunately ‘crop prob- lems’ are not an uncommon occurrence and presents as symptomatic with many dif- ferent illnesses and condi- tions. The Crop The crop is part of the digestive system and is an enlarged part of the esophagus at the foot of the neck where feed is (temporarily) stored and "moistened" with mucous and saliva from the mouth until the contents are moved into the stomach. A chicken has two stomachs, the proventriculus (the glandular stomach) and the gizzard or ventriculus (also called the muscular stomach). The feed is transported from the crop into the the glandular stomach which, as the name implies, is where secretory enzymes are added to the feed mass to aid in digestion; one of which is pepsin which in turn activates the stomach to produce hydrochloric (stomach) acid lowering the PH to aid in digestion and absorption of nutrients and also helps to dissolve the calcium grit (usually oyster shell) releasing the calcium in it. These enzyme-filled gastric juices infuse the feed as it moves onwards towards the gizzard (ventriculus or muscular stomach). The gizzard is a small organ and not able to deal with large quantities of feed. It is composed of two oval shaped and thick walled powerful muscles with a tough horny lining.

  • A. Pelvis 1. Name the Innominate Bones
    A. Pelvis 1. Name the innominate bones (those that are fused together and don’t move). There are two innominate bones, and each innominate bone contains three bones that are fused together. The three bones are the ilium, ischium, and pubis. They are placed laterally (on the side) on the pelvis, and each innominate bone has an acetabulum where the three bones fuse around it. The acetabulum is the concave surface of the pelvis, where the head of the femur meets with the pelvis to form the hip joint. 2. Describe the sacrum. The sacrum is a triangular shaped bone that has a superior base and an inferior apex. The anterior side of the sacrum is concave, while the posterior surface is convex. The sacrum consists of five vertebrae fused together. Attached by the sacroiliac joints, the sacrum lies between the innominate bones. The sacral promontory is the anterior and superior edge of the sacrum’s base (first sacral vertebra), and it protrudes forward forming the concavity. This protrusion into the cavity of the pelvis reduces the anteroposterior diameter of the pelvic inlet. If the sacral promontory was pushed backwards, it would widen the pelvic inlet and increase its diameter. 3. Describe the coccyx. The coccyx, or tailbone, is the final segment of the vertical column. It is also triangular and looks like a shortened tail at the bottom of the spine. It is composed of four vertebrae. The sacrococcygeal joint is between the superior side of the first coccygeal vertebra and the inferior side of the fifth sacral vertebra.

  • Evaluating and Treating the Gastrointestinal System
    CHAPTER 14 Evaluating and Treating the Gastrointestinal System STACEY GELIS, BS c, BVS c (Hons), MACVS c ( Avian Health) The avian gastrointestinal tract (GIT) has undergone a multitude of changes during evolution to become a unique anatomical and physiological structure when compared to other animal orders. On the one hand it has evolved to take advantage of the physical and chemi- cal characteristics of a wide variety of food types.1 On the other hand, it has had to do so within the limitations of the requirements for flight.2 To this end, birds have evolved a lightweight beak and muscular ventriculus, which replaces the heavy bone, muscular and dental structure characteristic of reptiles and mammals. The ventriculus and small intestine are the heaviest struc- tures within the gastrointestinal tract and are located near the bird’s centre of gravity within the abdomen. Greg J. Harrison Greg J. The overall length of the GIT is also less than that of a comparable mammal, another weight-saving flight adap- tation. Interestingly, these characteristics are still shared with the flightless species such as ratites and penguins. In addition, the actual digestive process needs to be rapid to support the high metabolic rate typical of flighted birds.3 Gastrointestinal adaptations to the wide range of ecolog- ical niches that birds occupy mean that birds can take advantage of a huge variety of foodstuffs. The GIT hence shows the greatest degree of diversity of all the organ systems between different avian taxa. However, the pres- sures of convergent evolution have also meant that many distantly related species have developed a similar gastrointestinal anatomy to take advantage of particular food niches.3,4 Examples of these will be presented in the discussion of each section of the GIT.
