Resumo
The objective of this essay was to evaluate the use of guava extract processing as an antioxidant
additive on the diet of Japanese quail matrices about the parameters on the matrices fertile
performance on posture phase and the newborn quail parameters in the quality and internal health
resulted from the eggs of these matrices. Three experiments were done in the School of Veterinary
and Animal Science in the Federal University of Goiás (EVZ/UFG) and in all three of them, it was
adopted the completely randomized design (CRD). In the first experiment, 384 Japanese quail
matrices were used, 288 being females and 96 males, distributed in 4 groups, following the level of
guava extract inclusion on the diet of the matrices, with a recurrence of 6 times each group, in a
total of 12 females and 4 males in each recurrence. The levels of guava extract inclusion were
0,0%, 0,3%, 0,6% and 0,9%. In the second experiment, it were collected 162 eggs from each group
during three days and at the end of the third day they were put in the incubator, in a total of 648
eggs. In the third experiment, 432 eggs were collected and put in the incubator in a factorial
arrangement that considered two periods of preincubation storage – 216 eggs with nine days and
216 eggs with 3 days – and the four levels of guava extract inclusion on the diet of the matrices.
The performance data results were submitted to the variance analysis and the quality data of the
eggs were submitted to the regression analysis. The newborn quails quality parameters were
submitted to the regression analysis. The hatch window were submitted to the Tukey’s test, the
embryo diagnosis and the score percentage were assessed by Fisher’s exact test, the villus height
analysis and intestinal crypt depth were submitted to the variance analysis. It was adopted in all the
analysis 5% of probability. The use of guava extract has not influenced neither the birds’
performance nor the physicochemical quality of the eggs. In the second experiment, there was no
statistical difference to the percentage of total hatch and the percentage of hatch/fertile, hatch
window and the quality score of the newborn quails among the four levels of extract inclusion. The
birth dispersal in the group with 0,0% of guava extract inclusion was lower than the other
dispersions. 0,3% level of inclusion, the guava extract promoted improvements in the newborn
quails intestinal health. In the third experiment, the guava extract inclusion was able to standardize
the birth dispersal in both storage periods and promote the maintenance of the newborn quails
resulted from the eggs stored for nine days. This study concludes that the use of the guava extract
has not affected the matrices’ fertile performance and helped to standardize the hatch window as
well as promoting intestinal health of the newborn quails.
