Abstract
ABSTRACT: The aim of the present study was to evaluate the zootechnical performance, intestinal mucosa, and reaction to infestation by the parasite Ichthyophthirius multifiliis in jundiá Rhamdia quelen larvae supplemented with Mentha piperita essential oil or sodium butyrate in their diets. Five diets were used over 30 days: diet free of additive inclusion, 0% (control); inclusion of 1% or 2% of M. piperita essential oil: EO1% and EO2%, respectively; and inclusion of 0.25% or 0.50% of sodium butyrate: SB0.25% and SB0.50%, respectively. The different diets were not able to inhibit I. multifiliis infestation. Supplementation with SB0.50% in their diets presented better performance in all zootechnical parameters analyzed, including a 54% increase in final weight and 70% in survival, and increased (P<0.05) both the villi width and the amount of goblet cells present in the intestinal mucosa by approximately 50%. In view of these results, dietary supplementation of R. quelen larvae with 0.50% sodium butyrate for 30 days is recommended.
Highlights
Herbal medicines and organic acids have great potential for use in aquaculture
Other authors have observed the development of anthelmintic activity from the addition of M. piperita essential oil (EO) in pirarucu Arapaima gigas against monogenean Dawestrema spp. (MALHEIROS et al, 2016); a reduction of 70% in the prevalence of monogenean in Nile tilapia Oreochromis niloticus (HASHIMOTO et al, 2016); and a cytotoxic effect against Ichthyophthirius multifiliis in an in vitro study (VALLADÃO et al, 2016)
This study evaluated the zootechnical performance, intestinal mucosa morphology, and reaction to challenge by the parasite I. multifiliis in jundiá R. quelen larvae fed diets supplemented with M. piperita EO or sodium butyrate
Summary
Herbal medicines and organic acids have great potential for use in aquaculture They are biodegradable and have antimicrobial activities against various bacteria, parasites and fungi (ADEL et al, 2015; AHMED & SADEK, 2015; KOH et al, 2016; VALLADÃO et al, 2016). They are a preventive alternative for maintaining the health of cultured fish, acting in the intestinal tract inhibit the growth pathogenic of bacteria, specially of Gramnegative bacteria, and improving fish digestibility and nutrient absorption, what may benefit zootechnical performance (ZHENG, 2009; TALPUR, 2014; ADEL et al, 2015). Other authors have observed the development of anthelmintic activity from the addition of M. piperita EO in pirarucu Arapaima gigas against monogenean Dawestrema spp. (MALHEIROS et al, 2016); a reduction of 70% in the prevalence of monogenean in Nile tilapia Oreochromis niloticus (HASHIMOTO et al, 2016); and a cytotoxic effect against Ichthyophthirius multifiliis in an in vitro study (VALLADÃO et al, 2016)
