This work evaluated the effects of dietary supplementation with seaweed, Pterocladia capillacea , nanoparticles (SN) on growth, whole-body composition, digestive enzyme activities, feed efficiency, immunological response, antioxidant activity, and gene expression whiteleg shrimp, Litopenaeus vannamei . The SN form was conducted using a Planetary Ball Mill PM 400. particle size verified through Dynamic Light Scattering (DLS) analysis. DLS showed that mean sizes were between 151 nm (13.6%) 835 (64%). Throughout 60 day experimental trial, postlarvae (PLs) L. subjected to one following five feeding groups. first group is commercially available shrimp as basal diet without any seaweed supplementation, functioning negative control (C 0% ). A second received commercial supplemented 2% (20 g/kg) dried powder (SP ), positive control. remaining three groups fed diets at concentrations 0.5% (SN 1% respectively. 750 postlarval (0.053 g/PL) allocated Each consisted 150 PLs (triplicate). their corresponding regime times 10% body weight. results revealed that, compared those ) or controls, increasing levels SN, especially growth (FW, WG, SGR), enzymes (amylase lipase activities), carcass composition (protein lipid contents), nutrient efficiency (FI, PI, FER, FCR, PER), activities (SOD CAT), innate immunity (LYS MDA), related-immunity expressions ( p53 significantly improved. In conclusion, these findings concluded applying nanotechnology tools enhances additives maximizes health, overall production.

Post-weaning Diarrhea (PWD) is a kind of physiological stress diarrhea in Rex rabbits after weaning, which can lead to death severe cases. Traditional Chinese medicine (TCM) has been widely used animal due its advantages natural origin, diverse functions, safety, reliability, economy and environmental protection. Modified Yupingfeng Granule (MYPFG) an improved prescription based on the famous traditional (YPF), combined with other TCM obvious synergistic additive activity order obtain excellent for PWD. In this study, 120 weaned were randomly allocated 4 treatment groups, including control (CON), low dose (LD), medium (MD), high (HD). Rabbits fed diet or different MYPFG proportions 30 days. The study 16S rRNA analysis intestinal microbiota cecal contents metabolomics explore effect rabbits. increased average daily gain, villus length crypt depth ratio decreased feed meat ratio, frequency, mortality rate, (p < 0.05). test found that could change abundances Patescibacteria, Sphingobium, Ruminococcus, Oxalobacter. Metabolomics may be related regulation Glycine, serine threonine metabolism, Arginine proline metabolism. Nicotinate nicotinamide regulate metabolic pathway some amino acids alleviate PWD

The present study investigated growth performance, body composition, hepatic and intestinal morphology, biochemical indices, transcriptomic responses, metabolomic profiles in giant freshwater prawn ( Macrobrachium rosenbergii ) fed six kinds of soy protein concentrate (SPC) diets over an 8‐week feeding trial. SPC were formulated by replacing varying proportions fishmeal (FM) with SPC, the final percentage FM set at 350, 280, 210, 140, 70, 0 g/kg, respectively, designated as F35, F28, F21, F14, F7, F0 diets. Results showed that weight (FBW), gain, specific rate (SGR) F35 greater than those F7 F0. crude lipid content was higher F28. Notably, increasing substitution levels disrupted hepatopancreas structural degradation becoming more pronounced beyond 40% replacement (F21). Compared to group, significantly decreased activity glutathione peroxidase (GSH‐PX), increases malondialdehyde (MDA) nitric oxide (NO) hemolymph. Based on transcriptomics, two differentially expressed genes (DEGs) LOC136825138 LOC136856310 consistently observed across all groups. metabolomics indicated 77 metabolites (DEMs) treatments. A negative correlation between eicosapentaenoic acid (EPA), arachidonoyl dopamine, 8Z,11Z‐eicosadienoic acid, vitamin E nicotinate. comprehensive analysis both data sets revealed substantial perturbations associated “alpha‐linolenic metabolism” “glycerophospholipid metabolism”. In conclusion, elevated dietary had detrimental effects health, antioxidant capacity, immune function M. . level for could be reduced 140 g/kg using a sole substitute, inclusion 211 diet.
