To evaluate the effect of the temporary replacement of shrimp ration (RC) by chicken ration (RF) in the culture of Litopenaeus vannamei shrimp, juvenils (1.07 ± 0.26 g), were cultivated (52/m2) for 30 days in 50 L boxes, with constant aeration, 0% of water exchange and fed with 10% of its biomass/day at 08:00 and 16:00 h, according to the treatments: (1) RC; (2) 1 week RC + 1 week RF, alternate; (3) RF and (4) 1 day RF + 1 day RC, alternate; with 5 repetitions each. There was no difference (P <0.05) in the weight of shrimp on the basis of treatments applied at the beginning (Kruskal-Wallis, P = 0003), 15 days (Kruskal-Wallis, P = 0.98) and at 30 days (Kruskal-Wallis, P = 0.07) to experiment. The Specific Growth Rate (rm ANOVA, P = 0.28) and survival (Friedman, P = 0,34 the animals were significantly similar, indicating that these parameters were not affected by treatments, with the possible replacement of shrimp ration by chicken ration, as a measure of containment of expenditure, for short intervals of time. Studies are needed to validate these results in earth ponds.
