HEMATOLOGY, SERUM BIOCHEMISTRY AND NUTRITION IN BIRDS: CRACIDAE
The family of birds Cracidae is usually included in the Order Galliformes, but the
Order Craciformes has recently been proposed. It is a truly arboreal family which possesses four biotypes: chacalacas, guans, piping guans and curassows. About one third of the cracid species were considered threatened 20 years ago, presently all 50 species are listed in the IUCN’s Red Data Book (2006) under several categories. They are one of the most threatened families of birds in the world and the most threatened in the Americas. Fortunately, cracids have good potential for reproduction in captivity and artificial techniques similar to the ones used in domestic Galliformes have been applied successfully. The nutrition traditionally utilized in captivity is mostly empirical, involving a great variety of items susceptible to selection by the animals, hence causing variable nutritional effects, especially when the animals are kept in groups. A more thorough understanding of the physiological implications of nutrition in captivity, this study was composed in two chapters.
The first chapter presents a review of the techniques for the study of blood biochemistry and hematology in birds, with emphasis on nutrition-related effects. There are also relevant aspects of bird nutrition and evolution, especially concerning Cracids. In the following chapter an experimental study, performed in captive cracids (Aburria jacutinga, Penelope obscura and Penelope superciliaris) fed two different diets, is presented. The diet traditionally applied in zoos, composed of commercial chicken feed, fruits and vegetables was converted to a specific extruded commercial feed for pheasants and wild Galliformes.
Keywords: Aburria jacutinga, Cracidae, hematology, nutrition, Penelope obscura, Penelope superciliaris, serum biochemistry.
