This Brazilian bird, pertaining to the Rheiforme order, Rheidae family and Rhea gender has outstanding itself by its reproductive, productive and adaptive characteristics. However, its optimum productive performance will depend on the adequate facilities and management that minimizes the harmful effects that can be caused by the environmental conditions. The aim of this work was to analyze the productive performance of rheas (Rhea americana) maintained over confinement, during its growth. The experiment was carried out in an experimental facility, in the Federal University of Viçosa, Viçosa City, Minas Gerais State, Brazil, during from April to May, 2004. Thirty six animals, 18 males and 18 females, with average initial weight of 4.7 kg for the females and 4.3 kg for the males were identified. They were distributed in couples in the internal boxes on the referred facility and maintained on the floor without litter. The main constructive characteristics of the facility were: width of 10.0 m, height of 3.50 m and 61.0 m of length. It was guided east-west. The diet attended the brazilian nutritional applications, considering these experimental animals in growth. The internal and the external environment were continually monitored. The animal performance was evaluated in accordance to the average alive weight (AAW) at the end of the experiment, which was of 7.7 kg. It was registered difference between the males and the females, this is, the males reached 7.6 kg and the females 7.8 kg. Those values were below the expected ones, usually about 9.5 kg, for animals with the same age.
