“…To prepare the diets, basal diet was mixed with the appropriate powders concentration and water, and sprayed on the pellets, which were allowed to dry for 18h at 45°C by air circulation and stored at 4°C until use. Control diet was prepared adding only water without herbal supplementation (Cerezuela, Cuesta, Meseguer, & Esteban, 2008;Akrami, Iri, Khoshbavar Rostami, & Razeghi Mansour, 2013). Fries were fed the experimental diet for 8 weeks in rate of 3-5% of the body weight per day, spread across three feeding times (06:00, 14:00 and 19:00).…”

“…In order to analyze the growth indices of the fish fry, all of fish from each tank were biometried and weighted once every 15 days during the experiment, at least 24-h after the last feeding (Akrami et al, 2013). At the end of the feeding trial, weight gain (WG%), specific growth rate (SGR; % day -1 ) and feed conversion ratio (FCR) were calculated according to the following formulas (Bekcan, Dogankaya, & Cakirogullari, 2006): WG (%) = 100 × (Wf-Wi)/ Wi FCR = dry feed intake (g)/wet WG (g) SGR (% day -1 ) = (Ln Wf-Ln Wi) × 100/t Where Wf and Wi are final and initial body weights, respectively and t is time in days.…”

The present study was aimed at determining the effects of medicinal herbs adjuvants on growth, hematoebiochemical parameters, some non-specific immunity and disease resistance to Photobacterium damselae in Sobaity sea bream (Sparidentex hasta). The fish (mean body weight 3.08±0.31 g) were fed fishmeal diets supplemented with either 1% of Garlic (Allium sativum), 1% supplemented of Ginger (Zingiber officinale), 1% supplemented of thyme (Thymus vulgaris), a mixture of these herbs (1% Garlic + 1% Ginger + 1% thyme), and control diet without medicinal herbs, for 8 weeks. The highest weight gains (WG %) and the specific growth rate (SGR) were in fish that fed diets with the mixture of three medicinal herbs (P<0.05). The number of WBC and RBC showed a significant increase in ginger and the mixture of three medicinal herbs compared to the control (P<0.05). The highest total protein and the lowest cholesterol levels were observed in treated groups with ginger diet (P<0.05). The highest albumin and the lowest triglyceride levels were achieved in mixture of these three herbsgroup. The analysis of AST and ALT were significantly decreased in the mixture of these three herbs and ginger groups (P<0.05). The lowest ALP level were showed in mixture of these three herbs group. Furthermore, serum lysozyme activity, total immunoglobulin (Ig) and complement activity (ACH50) were significantly increased in the mixture of three medicinal herbs fed fish and ginger groups (P<0.05). After feeding experiment, fish were infected with Photobacterium damselae strain FN1 and mortalities were recorded. The results of this study demonstrated that dietary mixture of three medicinal herbs and ginger groups could be an improvement in the growth and some non-specific immunity of Sobaity sea bream fry.

“…After 8 weeks of feeding, prior to sampling, fish from each cage were starved for 12 h according to Akrami et al [38], and then anesthetized in a benzocaine bath (50 mg/L) as described by Berdikova Bohne et al [39]. We quickly removed intestinal sections, which were classified according to the position of the turning in the intestine: proximal intestine being anterior to the first turning, mid intestine being the region located between the first turning and the last turning, distal intestine being posterior to the last turning [40].…”

“…The increase in LYZ activity suggests elevation of humoral factors that can protect the host against the invasion of pathogens (Harikrishnan et al, 2011). LYZ activity in fish can be modulated by various species of lactic acid bacteria (Panigrahi et al, 2004;Kim & Austin, 2006;Akrami et al, 2013), that, besides the contribution to digestion, can increase mucus production, which is the first line of defense against parasites and bacterial infections through its enzymatic system, where the lysozyme is present (Salinas et al, 2008). Once the MOS can be a selective substrate for this group of beneficial bacteria (Gibson & Roberfroid, 1995;Salze et al, 2008), the major enzymatic activities, observed in the group supplemented with 2 g MOS kg -1 , can be the result of the manipulation in intestinal microbiota.…”

ABSTRACT.A 28-day experiment was carried out to evaluate the effect of dietary prebiotic mannan oligosaccharide (MOS) on the growth, survival, intestinal morphometry and nonspecific immune response of the Siamese fighting fish (Betta splendens Regan, 1910) larvae. The MOS supplementation levels evaluated was: 0, 2, 4 and 6 g kg -1. Into 16 plastic aquaria (3 L) 240 larvae (4.21 ± 0.26 mm) were distributed at a density of 5 larvae L -1 . All larvae received live food for seven days, followed by a period of eight days of co-feeding (live food + inert diet) and, finally, 13 days of inert diet. At the end of feeding-trial, there were no significant differences between growth, survival, intestinal morphometry and alkaline phosphatase activity of larvae fed the control or MOS supplemented diets. However, the lysozyme activity in larvae fed 2 g MOS kg -1 was significantly higher compared to other treatments. For fish farming, the most beneficial effects of prebiotics reside in its ability to enhance the immune system of fish. In this context, this study revealed that, although the MOS supplementation has no effect on growth, survival and intestinal morphometry, 2 g MOS kg -1 supplementation for B. splendens larvae hint at a possible immunomodulatory effect, as evidenced by the increase in lysozyme activity.

Se realizó un experimento de 28 días para evaluar el efecto de la suplementación dietética con el prebiótico manano oligosacáridos (MOS) para larvas de peces luchadores siameses (Betta splendens Regan, 1910) sobre el crecimiento, la supervivencia, la morfología intestinal y la respuesta inmune inespecífica. Los niveles de suplementación fueron: 0, 2, 4, y 6 g L -1. Se distribuyeron 240 larvas (4,21 ± 0,26 mm) en 16 acuarios de plástico (3 L) a una densidad de 5 larvas L -1 . Todas las larvas recibieron alimento vivo durante siete días, seguido de un período de ocho días de co-alimentación (alimento vivo + dieta inerte) y, finalmente, 13 días de dieta inerte. Al final de la prueba de alimentación, no hubo diferencias significativas en el crecimiento, supervivencia, morfología intestinal y actividad de la fosfatasa alcalina entre las larvas alimentadas con la dieta control y las alimentadas con dietas suplementadas con MOS. Sin embargo, la actividad de la lisozima en las larvas alimentadas con 2 g MOS kg -1 fue significativamente mayor en comparación con los otros tratamientos. Para el cultivo de peces, los efectos más beneficiosos de los prebióticos residen en su capacidad para mejorar el sistema inmune de los peces. En este contexto, el presente estudio mostró que, a pesar de la administración del prebiótico MOS no tiene ningún efecto sobre el crecimiento, supervivencia y morfología...
