The current study explored the influence of dietary supplementation of Chlorella vulgaris dried powder (CV) with zinc-oxide-nanoparticles (ZnO-NPs), and/or selenium-nanoparticles (Se-NPs) on broilers' growth, antioxidant capacity, immune status, histological responses, and gene expression of some related genes. Several 200 one-day-old Cobb-500 male chicks were distributed into 5 groups with four replicates each. In the 1st group, birds were fed the basal diet (BD).

We used 300 fingerlings of Nile tilapia that were randomly distributed into 3 groups; each one was attributed to 5 replicates of 20 fish per aquarium with initial weight (gm) (156 ± 1.25).

We formulated five isonitrogenous and isocaloric experimental diets to incorporate BSFA at level of (0%, 15%, 30%, 45%, 60%). The growth performance parameters (FBW, BWG, SGR, PER, and FCR) revealed a significant increase in the BSFA30 tilapia group compared to the control group followed by BSFA45 (P < 0.

This study investigates the effects of different sources of selenium (inorganic (SSE), organic (OSE), and elemental nano-selenium (NSE)) on the performance of Nile tilapia (Oreochromis niloticus). In total, 204 Nile tilapia fingerlings were randomly divided into 4 equal groups fed 1 of 4 diets: a control (adding no selenium) and 3 diets as selenium sources (1 mg/kg diet), After a 65-day feeding trial, the growth performance parameters of Nile tilapia were significantly enhanced by dietary selenium supplementation (P < 0.05), with the highest values recorded in the OSE- and NSE-supplemented groups.

In this study, 750 healthy fertile eggs from the local chicken breed Dokki-4 strain were analyzed. Fertile eggs were randomly divided into five experimental groups (150 eggs/3 replicates for each group).

This study assessed the combined impact of Aspergillus oryzae-fermented OC (AFOC) on the growth performance, intestinal morphometry, blood biochemistry, lysozyme activity, gut immune-related genes, and flesh quality of Nile tilapia. We divided 225 fish into five groups and further subdivided into three replicates (n = 15 each) and fed them five diets (Control, AFOC5, AFOC10, AFOC15, AFOC20) to determine AFOC nutritional value and its optimized incorporation level in the diet.

One hundred and twenty, 8-week-old birds were randomly assigned to 1 of 4 dietary treatments in 3 replicates (10 birds/replicate). The treatments contained inorganic sodium selenite (SS) at 0.

There is a widespread antimicrobial resistance among serotypes, and innovative solutions to antibiotic resistance are needed. We aimed to use probiotics to reduce antibiotic resistance and identify the major probiotic players that modify the early interactions between and host cells.

Ninety-one-day-old chicks (Ross 308) were randomly assigned to one of three dietary treatments in three replicates, in a feeding trial that lasted for 5 weeks. Birds were fed a basal diet supplemented with inorganic zinc oxide at 40 mg/kg diet (control), zinc oxide nanoparticles (ZnONPs) at 40 mg/kg diet (ZN1), or ZnONPs at 80 mg/kg diet (ZN2).
