There are about 10,000 avian species arranged in 27 orders. In Egypt, RABBITS are roughly included with poultry although they are mammals.

  10. 10. 10 2-Absence of the teeth and the lips. The lips are replaced by horny keratinized beaks of different shapes according to the nature of the avian species. Beaks are used for pecking either pecking of feeds or pecking of other birds for enacting the dominance "Pecking behavior". De-beaking is a process which is used for removal of about one third of the beak to control of cannibalism. ‫ر‬ ‫ا‬ ‫ل‬ ‫أ‬Shapes of beak 3-Presence of comb and wattle in chickens = Snood and caruncles of turkey. ‫أس‬ ‫ﺹ‬ ‫ا‬ ‫ی‬ ‫ا‬ ‫اآ‬ ‫ا‬Structures of heads ‫ف‬ ‫ا‬ ‫ل‬ ‫أ‬Shapes of comb:

  15. 15. 15 Internal anatomy Respiratory characteristics 1-The avian lung is non-tidal = hepatized i.e. can not inflated by air. The mammalian lung is tidal = spongy i.e. can be inflated by air.
  16. 16. 16 The differences between respiratory system of poultry and mammals. Criteria Avian respiratory system Mammalian Respiratory system Lung Non tidal = hepatized Tidal = Spongy Air sacs Present Not Pneumatic bone Present Not Respiration Unidirectional bi-phasic air flow Bidirectional uni-phasic air flow Efficiency Extremely efficient Efficient 2-The presence of air sacs. They are nine in number in most avian species and take their names from their situation as follows: 1-Cervical air sac: one pair of air sac present in the cervical region. 2-Interclavicular air sac: single air sac present in-between the inter-clavicle bone. 3-Anterior thoracic air sac: one pair of air sac present in the anterior region of the thoracic cavity under the lung. 4-Posterior thoracic air sac: one pair of air sac present in the anterior region of the thoracic cavity between the lung and the genital organs. 5-Abdominal air sac: one pair of air sac presents behind to the last rib and extends into the pelvic cavity. ‫س‬ ‫آ‬ ‫ا‬‫اﺉ‬ ‫ا‬Air sacs:‫وﺕ‬ ‫أ‬ ‫آ‬ ‫ﺕ‬ ‫س‬ ‫أآ‬ ‫ه‬‫ا‬ ‫أﺕ‬‫ی‬ ‫ا‬ ‫و‬ ‫ا‬ ‫م‬ ‫ا‬ ‫ﺉ‬ ‫ا‬‫ا‬ ‫ﺉ‬ ‫وا‬ ‫زي‬ ‫ا‬ ‫دل‬ ‫ا‬ ‫م‬ ‫وا‬ ‫آ‬ ‫وا‬ ‫اء‬ ‫ا‬ ‫ی‬ ‫ﺕ‬‫ا‬ ‫زن‬ ‫ا‬ ‫آ‬ ‫ﺉ‬ ‫ی‬ ‫ی‬ ‫ﺉ‬ ‫ا‬‫و‬ ‫ان‬ ‫ا‬‫ا‬ ‫ﺉ‬ ‫ا‬‫ا‬ ‫ل‬ ‫ﺡ‬ ‫اﺥ‬ ‫ا‬ ‫ارة‬ ‫ا‬ ‫در‬ ‫آ‬ ‫ی‬ ‫ا‬ ‫ت‬ ‫اﻥ‬ ‫ا‬ ‫ج‬ ‫ﻥ‬ ‫خ‬ ‫ا‬ ‫ی‬Spermatogenesis.

Immunological characteristics
  31. 31. 31 1-There is no lymph nodes in avian species except for ducks, geese and swans in which there are two primitive lymph nodes. They are the cervico-thoracic node and the lumber nodes. 2-The avian erythrocytes are "nucleated" and the avian neutrophils are modified to heterophils and the avian blood platelets are true cells i.e. "nucleated" and known as thrombocytes. -‫اء‬ ‫ا‬ ‫م‬ ‫ا‬ ‫ات‬ ‫آ‬ ‫ﺕ‬Avian RBCs‫ا‬ ‫ی‬ ‫وﺥ‬Thrombocytes‫اة‬ ‫ﻥ‬ ‫ن‬ ‫ر‬ ‫ا‬Nucleated‫ا‬ ‫ا‬ ‫ا‬ ‫ا‬ ‫ا‬ ‫ا‬ ‫آ‬ ‫ن‬ ‫ی‬ ‫ی‬-1Major histocompatability complex-I‫ن‬ ‫ی‬ ‫و‬ ‫دور‬ ‫ا‬ ‫ﺕ‬. 3-The presence of bursa of Fabricius. It is a unique organ and not present in any animal except for birds. 4-Avian antibodies are three only. They are IgM, IgG and IgA. There is no IgD and IgE. Absence of IgE means absence of anaphylaxis in birds. Thermoregulatory characteristics Warm-blooded = homothermous i.e. their body temperature is constant whatever the ambient temperature. No sweat gland in birds and so they are highly susceptible to the heat stress.
