Abstract:

Globally, aquaculture has grown exponentially in recent years. Tilapia (Oreochromis spp.) is one of the most exploited species. However, Streptococcus iniae is a serious threat to the sustainability of aquaculture. The use of phytobiotics such as Capsicum annuum oleoresin offers a sustainable alternative to improve the performance of fish. It is believed that the oleoresin of Capasicum annuum has favorable effects on the physiological state of Oreochromis niloticus on infection by Streptococcus iniae. The objective of this work is to evaluate the effects of the diet with the oleoresin of C annumm on the physiological state of tilapia (Oreochromis niloticus) against S. iniae. For this study, we used 120 fish (O niloticus) weighing 30-50 gr. A 2x3x3 experimental factorial design was used, with two doses of S. iniae infection by intraperitoneal inoculation (0 and 400 μl), three doses of oleoresin (0, 1 and 2 ml / kg of feed) and three evaluation times at 2, 15 and 30 day post inoculation (dpi). Microbiological analysis and calculation of the productive parameters was carried out. In addition, the physiological status of tilapias was evaluated in each treatment, by recording the hematological parameters, blood chemistry, and immunological parameters. No significant differences were found for the values of red blood cells, hemoglobin and hematocrit. White blood cells showed a significant increase at 2 dpi (P 0.001). The total proteins had lower levels for the treatments with 2 ml of oleoresin (P 0.000) at 30 dpi (P 0.021). Albumin presented a significant difference (P 0.000) with values below the control in the treatments with 2 ml of oleoresin. IgM presented higher levels at 15 dpi in the treatments with 1 ml of oleoresin than control (P 0.024).
