“…There are no studies dealing with dietary addition of citral and digestive enzymes. The dietary addition of the microencapsulated EO of C. flexuosus did not change the activity of intestinal trypsin and chymotrypsin in silver catfish (RAMPELOTTO et al, 2018). The same authors suggested that the increased carcass yield and protein content verified in this species Michelotti et al…”

“…Dietary addition of 1 or 3 mL of microencapsulated EO of C. flexuosus (contains α-citral 45.7% and β-citral 32.1%), did not change growth parameters of silver catfish, but the duration of the experiment was only 30 days and the fish were adults. The group fed with 1 mL microencapsulated C. flexuosus EO per kg of feed increased carcass yield and protein deposition, but reduced the gonadosomatic index and fat deposition in comparison to the control group (RAMPELOTTO et al, 2018). Therefore, the effect of citral and EOs containing this compound as major constituent on fish growth varies according to the species and other compounds present in the EOs.…”

“…Citral is the main compound of Aloysia triphylla EO (essential oil), whose dietary addition improved growth and oxidative status of silver catfish, Rhamdia quelen (ZEPPENFELD et al, 2016(ZEPPENFELD et al, , 2017. Dietary supplementation with the microencapsulated EO of Cymbopogon flexuosus, which also has citral as the main compound, increased carcass yield and protein deposition in silver catfish (RAMPELOTTO et al, 2018). Often the major EO component is primarily responsible for its biological activities, but dietary supplementation with citral did not improve oxidative parameters and innate immunity in common snook (MORI et al, 2019).…”

Essential oils of plants whose main compound is citral showed beneficial effects when added to fish feed. The objective of the present study was to evaluate the dietary effect of the addition of citral on zootechnical parameters and digestive enzyme activities of Centropomus undecimalis. Juveniles were fed for 45 days with diets containing different amounts of citral (0.0 - control, 0.5, 1.0, and 2.0 mL per kg of diet). The water quality parameters were kept stable during the experiment and no mortality was observed. At the end of the experimental period, the treatment 0.5 mL citral per kg of diet had the lowest weight gain and specific growth rate, and the highest feed conversion, while the same parameters did not differ between the other treatments. Pepsin activity was higher in the stomach of fish fed with 0.5 mL citral per kg of diet and amylase activity was higher in the intestine of fish fed with 0.5 and 2.0 mL citral per kg of diet compared to the control group. Intestinal lipase activity was higher in all groups that were fed with citral compared to the control group. Chymotrypsin and trypsin activities showed no difference between groups. Consequently, dietary addition of citral at any of the levels tested is not recommended for common snook.

Effect of Lippia grata essential oil as a feed additive on the performance of tambatinga juveniles

et al. 2022

Lippia grata (formerly known as Lippia gracillis) is an aromatic plant native to Brazil, with leaves rich in essential oils that possess significant biological activities. We evaluated the effect of essential oil of L. grata (EOLG) as a dietary additive on the growth, somatic indices, and biochemical parameters of juveniles (5.25 ± 0.26 g) of tambatinga, a hybrid fish obtained by crossing tambaqui (Colossoma macropomum) with pirapitinga (Piaractus brachypomum) of great economic importance in north and northeastern Brazil. We evaluated four dietary treatments, consisting of EOLG supplemented at 0.0, 0.5, 1.0, and 2.0 mL kg-1, over 60 days. Carcass yield was significantly higher in fish fed all EOLG diets compared to those fed the control diet (0.0 mL kg-1). Animals that received the 0.5 mL kg-1 treatment gained significantly more weight and showed a higher specific growth rate than those treated with 1.0 and 2.0 ml kg-1 EOLG, although none differed significantly from the control. The feed conversion rate was significantly lower in the 0.5 than in the 1.0 mL kg-1 treatment. Compared with higher concentrations, the diet containing 0.5 mL kg-1 EOLG increased the use of muscle glycogen, glucose, and lactate to meet energy demands, avoiding the use of muscle protein. Our results suggest that dietary supplementation with EOLG significantly improves carcass yield in tambatinga juveniles but that concentrations above 0.5 mL kg-1 may compromise growth rates and carbohydrate metabolism in this fish.

“…Essential oils from Aloysia citriodora (syn. A. triphylla) and Cymbopogon exuosus improved growth and oxidative status (Zeppenfeld et al, 2016(Zeppenfeld et al, , 2017, protein deposition and carcass yield when added to the diet of silver cat sh Rhamdia quelen (Rampelotto et al, 2018), and growth in Nile tilapia Oreochromis niloticus (Souza et al, 2020a, b). Furthermore, in these studies it was also proven that citral (3,7-dimethyl-2,6-octadienal) is the major compound of these essential oils, whose compound demonstrates antimicrobial, antifungal and antiparasitic characteristics, making citral a natural food additive (Maarse, 1991;Saddiq and Khayyat, 2010;Zheng et al, 2015;Berk, 2016).…”

This study evaluated the effects of dietary supplementation with citral on growth performance and intestinal parameters, and specific activity of the digestive enzymes of the Brazilian sardine Sardinella brasiliensis. The experiment was structured with two hundred and forty juvenile S. brasiliensis that were randomly distributed in a recirculating aquaculture system (RAS) composed of 12 circular tanks of 150 L (n = 20 per tank). A diet without citral addition (control) and three diets containing different levels of citral inclusion (0.5, 1.0 and 2.0 mL kg feed–1) were used in the fish feeding management during 20 days. After the period of dietary supplementation, the growth performance indexes of the fish were verified. Portions of the stomach and midgut were collected for analysis of digestive enzymes, as well as portions of the midgut for histological analysis. A significant positive relationship was found between citral supplementation and fish survival. In the specific activity of digestive enzymes, dietary citral supplementation at 2.0 mL kg feed–1 increased lipase and amylase activity. Citral supplementation positively influenced the number of villi and intestinal crypt depth. Furthermore, the inclusion of citral at 0.5 mL kg feed–1 increased the intestine diameter of the fish. However, the specific growth rate, weight gain and feed conversion were impaired with inclusions of citral at 0.5 and 1.0 mL kg feed–1. The results of the experiment suggest that the addition of citral as an additive in the diet of S. brasiliensis improved the survival of fish reared in RAS.
