Essay for prebiotic use in the feeding of nestlings of blue-fronted amazon in rehabilitation process

Abstract

Brazil presents one of the biggest biological diversities. The Blue-fronted Amazon (Amazona aestiva) is one of the most popular parrots in the world. There are few researches about nutrition of this bird and prebiotics may be an alternative to improve the sanitary conditions of this kind of birds. It was aimed
to evaluate the effect of the addition of the mannanoligosaccharide for five days in the diet of Bluefronted
Amazon nestlings in rehabilitation process. A completely randomized design with third-six apprehended parrots were used in two treatments and six repetitions with three birds per experiment unit. The birds of control group (TCO) were fed with pasty diet corn flour, ration for dogs and water, while the diet of
the experimental group (TMO) was composed by the addition of 1.5g of mannanoligossacharide by kilo of ration during the first five days of treatment. In the 6th day, the birds of the group TMO started to receive only TCO diet. They were weighted on 1, 16, 25, 32 and 61 days. The results were evaluated by F test in variance
analysis and regression analyses. The average weights at the beginning of the experiment had been 289.3±22.0 g for the birds of control group and 289.8±17.1 g for the birds of the experimental group. In the 61° day the weights obtained had been 321.5±21.1 g, 332.2±11.6 g, for treatments TCO and TMO, respectively. There were not significant differences between the averages of the treatments. So, the addition of the prebiotic
mannanoligosacharide for only five days in the diet did not influence in the development of the experimental birds in rehabilitation process. There were no mortality among the birds.
