Different herbs and spices have been used as feed additives for various purposes in poultry production. This study was conducted to assess the effect of supplemented with black pepper (Piper nigrum), turmeric powder (Curcuma longa), coriander seeds (Coriandrum sativum) their combinations on performance broilers. A total 210 (Cobb) one-d-old chicks were divided into seven groups 30 birds each. The treatments were: a control group received no supplement, 0.5% (T1), (T2), 2% (T3), mixture (T4),...

The present study was designed to evaluate the effects of ethanolic extracts Hypericum perforatum (HP), Origanum vulgare (ORG), and Melissa officinalis (MOF) on Nile tilapia (Oreochromis niloticus) juveniles. Fish (16.92 ± 0.28 g) were randomly divided into seven groups fed diets with 0 % (CTR), two levels (0.2 0.5 %) from each plant extract for 60 days. Final body weight, weight gain %, specific growth rate, feed conversion ratio significantly improved in ORG MOF at (P < 0.05). Moreover,...

Abstract We investigated the dietary effects of single application Saccharomyces cerevisiae , Lactobacillus bulgaricus and their combination on growth, proximate composition whole fish body, antioxidant defense, histoarchitecture hapa-reared Mugil capito . Healthy (Fish weighed = 10.30 ± 0.10 g at first) were randomly allocated into 4 equal groups, each with three replicates. These groups designed as follows: (1) a group fed basal diet without probiotics (control), (2) containing S. (4 g/kg...

The aim of the present study was to examine effects dietary inclusion fermented poultry by-product meal (FPBM) on growth performance, digestive enzymes activity, innate immunity, and antioxidant capacity in Nile tilapia (Oreochromis niloticus). A basal diet containing fish soybean considered as a control (Con), four other diets were produced by 10, 20, 30, or 40% FPBM (FPBM10, FPBM20, FPBM30, FPBM40 diets). experiment done triplicates (20 per replicate) fed test visual satiety twice daily...

The current study evaluated the effects of dietary mannanoligosaccharide (MOS) on red sea bream (Pagrus major) performances. Fish fed five levels MOS at 0, 0.5, 1, 1.5 or 2 g/kg for 60 days. results showed that supplementation significantly increased final body weight, weight gain, and specific growth rate with decreased feed conversion ratio especially in fish g per kg diet (P < 0.05). hematocrit level was while, total serum protein 1 comparison control. However, glutamic pyruvic...

The present study evaluated the impacts of powdered Astragalus membranaceus extract (AME) on growth, physiological responses, and serum immunity Pangasianodon hypophthalmus juveniles. Four test diets were formulated to include varying AME levels as 0.0 (control), 1.5 (AME1.5), 3.0 (AME3.0), 4.5 (AME4.5) g/kg. Fish weighing approximately 11.50 g stocked into four triplicate groups hand-fed three times daily for two months. At 60 days post-feeding, growth performance, including weight gain...

The date palm ( Phoenix dactylifera ) seeds were utilized in some traditional medical remedies and have been investigated for their possible health benefits. This proposed study wanted to assess the effect of (DPS) dietary supplementation comparison mannan‐oligosaccharides (Bio‐Mos®) β ‐glucan over antioxidant immunity events that on growth carcass performances broilers. An aggregate 180, one‐day‐old, chicks raised wire‐floored cages allotted into control, Bio‐Mos (0.1% Bio‐Mos), ‐glucan),...

Varied levels of Saccharomyces cerevisiae-fermented date palm seed meal (DSM) were included in Nile tilapia (26.95 ± 0.01 g) diets. Five diets prepared to include fermented DSM at 0, 5, 10, 15 and 20 % fed for fish 8 weeks. The obtained results revealed that yeast significantly affected the final body weight, weight gain, specific growth rate, feed conversion ratio a dose dependent manner (P = 0.001, P 0.002, 0.004, 0.01, respectively). Dietary increased lipase, amylase, protease activities...

Edwardsiella ictaluri is a Gram-negative intracellular pathogen that causes enteric septicemia of catfish (ESC). Successful vaccination against pathogens requires T cell priming by antigen presenting cells (APCs) bridge innate and adaptive immunity. However, the evidence on immunological mechanisms underscore E. pathogenesis protective role live attenuated vaccines (LAVs) scarce. We assessed expression immune genes related to presentation real-time PCR distribution patterns Langerhans-like...

The study aimed at evaluating the possible feeding strategies of selenium (Se) nanoparticles on performances European seabass (Dicentrarchus labrax). first group fed basal diet continuously (control) while second offered Se (1 mg/kg diet) every day (R1). third one then other (R2), and fourth for two days (R3). FBW, WG, SGR were significantly improved in R1 than fish groups (P < 0.05). FCR was reduced by to R1, R2, R3 control with lowest being had enhanced values Hb, RBCs, WBCs Additionally,...

In this paper, a mathematical model was used to evaluate dynamical hybrid system for optimizing and controlling the efficacy of plant‐based protein in aquafeeds. Fishmeal (FM), raw rapeseed meal (RM), fermented with yeast (RM‐Yeast) fungi ( Aspergillus oryzae RM‐Koji) were as test ingredients determination apparent digestibility coefficients (ADCs) dry matter, crude protein, lipid, energy, essential amino acids (EAA) olive flounder Paralichthys olivaceus , 7 ± 0.02 g) using diets containing...

Edwardsiella ictaluri (E. ictaluri), a Gram-negative, intracellular, facultative bacterium, is the causative agent of enteric septicemia catfish (ESC), which one most significant diseases farmed channel catfish. Macrophages have critical role in major defense mechanisms against bacterial infections by migrating to site infection, engulfing and killing pathogens, priming adaptive immune responses. Vaccination with E. live, attenuated vaccine (LAV) strains increased efficiency phagocytosis...

Unstable outdoor farming conditions weaken fish's health status and immunity, leading to high susceptibility infectious diseases low productivity. Feed additives have been applied recently enhance the growth performance well-being of striped catfish. This study evaluated effects ginger (Zingiber officinale) on performance, digestive enzyme activity, antioxidative response, antibacterial capacity Control three test diets were supplemented with rhizomes powder at 0.5 %, 1 1.5 %. After 90 days,...

Canola meal (CM) is commonly used in poultry diets; however, its use limited due to anti-nutritive factors. Therefore, this study was conducted evaluate the effects of feeding various levels canola with or without multi-enzyme supplement on broiler chickens. Four CM (0, 5, 10 and 20%) were (0 300 g/ton diet) a factorial design 4 × 2 8 dietary combinations. During experimental period (0-42 d age), inclusion at level 5 10% 20% decreased body weight gain gain:feed ratio compared control (CON; P...

The current study was established to test the possibility of using exogenous digestive enzymes (EDE) in rabbitfish (Siganus rivulatus) diets. Five experimental diets containing 34% soybean meal were prepared and supplemented with EDE at 0, 1, 2, 3, 4 g kg-1 diet. Fish average initial weight (± 1.1 g) fed for 74 days.
