Feather length in broilers is potentially important for (sexing-day old chicks     welfare    both).

                    List three unique aspects of the avian respiratory system when compared with mammals:

     1.

     3.

1.     The respiratory system is an (important    unimportant) component of a bird’s ability to fly.  The breast muscles are the largest muscles in (pelicans     broiler chickens    both) because of their importance to the overall process of flight (True    False).

  The crop in (chickens    turkeys    pigeons    all) is an essential anatomical feature because of its involvement in the early nutrition of hatchlings.  Some commercial (broilers     turkeys   both) can exhibit a condition called (pendulous crop   recessed crop    fermentative crop).

    The proventriculus in poultry is analogous to the (esophagus    stomach) in mammals. 

1.     The gizzard is primarily a (grinding   mixing) GI organ in avians that would be more important to birds consuming (whole grains    pelleted feed   mash feed).  Supplemental (grit   scratch grains) are popular with backyard flock owners to enhance the function of the gizzard.

High levels of mycotoxins in poultry feeds can often be diagnosed by visual examination of the (oral cavitity         lining of the gizzard      both

     Coccidiosis is a (bacterial    parasitic       viral) disease that only effects poultry (True    False).

It is most noticeable in the (small intestine    ceca      both) and can result in

(blood in the excreta    mortality    reduced body weight   All).  The control of coccidiosis can be accomplished by (medications in the feed       immunity         both).

1.     The excretion of excess dietary nitrogen by (poultry     robins      both) is in the form of

(uric acid       urea) which is similar to mammals (True     False).

The stimulatory effects of changes in the daily photoperiod are mediated via signals through the (optic   vagal) nerve to the avian (ovary   brain   both).

1.     Ovarian development of yellow follicles in poultry occurs through the (daily    weekly) deposition of lipid synthesized by the liver  (True   False). In young hens in the early stages of production, excessive lipid deposition in developing follicles can result in the production of eggs with (single    double   both) yolks.

1.     The testes in male (chickens    ducks    turkeys     all) are located (inside    outside) the body cavity and therefore are exposed to consistently (higher   lower) temperatures than what would occur in mammals.

1.     Ducks and chickens are similar in that sperm is deposited near the opening of the vagina and not via penetration of the penis (True    False).

All eggs contain approximately the same quantity of egg shell (True     False) so as the size of an egg (increases      stays the same) as a hen ages, egg shell quality normally declines (True   False).

 Under the influence of estrogen, a specific type of bone is formed that contains a highly    (soluble       insoluble) form of calcium.  This type of bone is specific to birds/poultry and developed after birds evolved from dinosaurs   (True     False).
