Abstract Poultry meat and eggs are considered as major sources of food for rapidly increasing human population across the globe. During rearing poultry, different antibiotics were included in poultry diets sub therapeutic doses to attain improvements growth performance.

Pollution is a critical concern of modern society for its heterogeneous effects on human health, despite widespread lack awareness. Environmental pollutants promote several pathologies through different molecular mechanisms. Pollutants can affect the immune system and related pathways, perturbing regulation triggering pro-inflammatory responses.

Annually, 3000-3500 tons of sea urchins are harvested in the Mediterranean Sea, with only their gonads being consumed (10-30% total weight), leaving rest as waste. This waste, consisting skeleton, is rich biominerals, mainly calcium a small amount magnesium, and contains potent antioxidant compounds. Considering issues resource overconsumption, line circular economy concept, this study explored potential replacing limestone-derived urchin waste diet laying hens, which require element to produce eggs. The experiment involved two groups hens: one receiving control containing calcium, another fed an experimental alternative source calcium. Parameters such egg production, animal welfare, quality, bone breaking strength were assessed. Additionally, activity carotenoid content diets evaluated, revealing no significant differences between groups. Both exhibited similar production rates; however, treated group had lower percentage discarded eggs fewer lesions on head, back, tail, indicating better welfare. produced significantly thicker shells, though observed eggshell weight, strength, ultrastructure. There also yolk colour or Similarly, found tibia confirming that can provide bioavailable without compromising quality. In conclusion, substituting hens' positively affected welfare improved thickness suggesting be recycled valuable feed. However, further research necessary confirm these findings.

The modulation of gut microbiota presents a promising avenue for improving livestock health, productivity, and sustainability. Traditional strategies such as probiotics, prebiotics, synbiotics have demonstrated effectiveness in enhancing health immune function while reducing the reliance on antibiotics. Recent advances introduced innovative approaches, including postbiotics, fecal transplantation (FMT), precision biotics, to emerging synthetic biology applications bacteriophage therapy, offering targeted interventions with potential high specificity efficacy. However, successful integration into agricultural systems requires navigating complex regulatory frameworks addressing safety, scalability, economic feasibility concerns. This chapter aims critically assess traditional, advanced, strategies, evaluating their mechanisms, applications, limitations highlighting transformative achieving sustainable production global public challenges. offers practical guidance veterinarians, researchers, policymakers, producers seeking integrate microbiota-based modern operations.
