“…The increased FCR recorded in fish fed supplemented diets than the control is similar to the report of [27] who revealed that inclusion of 1.5% walnut leaf increased FCR in the supplemented groups than the control. This was also corroborated by [33] which showed that the addition of Propolisethanolic extract and crude propolis increased the FCR, FER and PER in the supplemented groups when compared with the control. The findings of [34] who showed that were no significant differences (P>0.05) in FCR among all dietary ginger powder treatments which conformed to the result obtained in this study.…”

Growth, haematology and histopathology are important indices in evaluating the health and physiological state of fish. These metabolic and health indices were examined in Clarias gariepinus fed with Zingiber officinale (ginger) roots-powder supplemented diets in 40-litre freshwater-filled plastic tanks. 120 C. gariepinus fingerlings (weight, 2.33±0.07g) were fed with 40% crude protein diets containing three concentrations of Zingiber officinale roots-powder: GRP1-1%; GRP2-2%; GRP3-3%, and control-0% ad libitum twice daily for 12 weeks. Significant differences (p < 0.05) occurred in the growth parameters except feed conversion ratio and specific growth rate. Survival rate decreased as concentration of powder increased. Differences (p<0.05) seen in packed cell volume (PCV), Haemoglobin (Hb), and Red blood cell (RBC), thus highest in GRP3: PCV (37.00±1.16%), Hb (12.37±0.37g/dl) and RBC (3.47±0.08 x 10 6 /l) and lowest in control: PCV (22.00±0.58%), Hb (7.37±0.20g/dl) and RBC (2.07±0.06 x 10 6 /l). Liver histology of control fish was normal, while fatty degenerations were seen in the treated fish. The histology of fish kidney was normal in all treatments. The study concluded that 1% ginger root-powder dietary supplementation in cultured C. gariepinus could effectively improve the metabolic activities, health profile and survival of the fish.

“…It has been reported that dietary propolis supplement, regardless of the inclusion level, decreased the whole body moisture and ash contents, but increased the whole body protein and lipid contents (Deng et al, 2011). Propolis extract (Meurer et al, 2009) or crude propolis (Abd-El-Rhman, 2009) decreased the feed conversion ratio and increased the growth performance (Abd-El-Rahman 2009;Meurer et al, 2009), improved the specific growth rate (Deng et al, 2011), decreased the tonus and amplitude of the peristaltic movements in rats (Cristina et al, 2007) as well as improved the growth performance in poultry (Seven, 2008). On the other hand, while HBP inclusion in diet improved SGR, final weight and length of female O. niloticus, it had no effect on body indices or the growth performance in males when compared to control.…”

This study aimed at identifying the effects of propolis and honeybee pollen (HBP) on growth performance, fecundity and some hematological indices of liver and kidney functions of Nile tilapia ''Oreochromis niloticus'' supplemented with 2.5% of propolis or HBP in diet for 21 days. The results showed that dietary propolis or HBP significantly (P<0.05) improved Specific Growth Rate (SGR), Average Daily Gain (ADG) and Feed Efficiency ratio (FER). Propolis significantly (P<0.0001) increased the percentage of O. niloticus with ripened eggs. Microscopically, the ovaries were seen to contain a large number of oocytes >4 mm in the treated groups. In male, HBP feeding significantly (P<0.05) increased testicular weight, gonadosomatic index and improved the semen quality. Nevertheless, propolis treated males showed a significant (P<0.05) increase in head abnormalities among all groups. Sections from the testes of HBP-fed group appeared highly active and showed accumulated sperms in seminiferous tubules. Propolis or HBP significantly (P<0.001) decreased the serum ALT. Concluding that, supplementation of fish diet with either propolis or honeybee pollen is promising a beneficial effect for fisheries due to its potential improving effect on the growth rate and fecundity and preserving some biochemical indices of liver and kidney functions of O. niloticus.

“…Propolis has been successfully used as a growth enhancer and immuno-modulator in several fish species (Abd-El-Rhman, 2009;Deng et al, 2011;Bae et al, 2012). Research has correlated its capacity as a growth enhancer to its antimicrobial, anti-parasitic, and immune-stimulant properties (Meurer et al, 2009;Segvic-Bubic et al, 2013;Uczay et al, 2014), although to our knowledge, no studies have investigated the effect of propolis on fish morphology and muscle gene expression.…”

ABSTRACT. Propolis can be used as growth enhancer due to its antimicrobial, antioxidant, and immune-stimulant properties, but its effects on morphometry and muscle gene expression are largely unknown. The present study evaluates the influence of propolis on muscle morphometry and myostatin gene expression in Nile tilapia (Oreochromis niloticus) bred in net cages. Reversed males (GIFT strain) with an initial weight of 170 ± 25 g were distributed in a (2 x 4) factorial 2 E.L. Buck et al.Genetics and Molecular Research 16 (1): gmr16019404 scheme, with two diets (DPRO, commercial diet with 4% propolis ethanol extract and DCON, commercial diet without propolis, control) and four assessment periods (0, 35, 70, and 105 experimental days). Muscles were evaluated at each assessment period. Histomorphometric analysis classified the fiber diameters into four groups: <20 mm; 20-30 mm; 30-50 mm; and > 50 mm. RT-qPCR was performed to assess myostatin gene expression. Fibers < 20 µm diameter were more frequent in DPRO than in DCON at all times. Fiber percentages >30 µm (30-50 and > 50 µm) at 70 days were 25.39% and 40.07% for DPRO and DCON, respectively. There was greater myostatin gene expression at 105 days, averaging 1.93 and 1.89 for DCON and DPRO, respectively, with no significant difference in any of the analyzed periods. Propolis ethanol extract did not affect the diameter of muscle fibers or the gene expression of myostatin. Future studies should describe the mechanisms of natural products' effects on muscle growth and development since these factors are highly relevant for fish production performance.
