Effect of Omega-3 Fatty Acid Supplementation on Broilers' Health and Meat Quality-Systematic Review.
Review in Animals : an open access journal from MDPI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Omega-3 polyunsaturated fatty acids are increasingly applied as functional nutrients to improve broiler health, metabolic resilience, and meat quality. However, studies remain inconsistent regarding optimal inclusion levels and their efficacy. This systematic review was conducted following PRISMA 2020 guidelines. This study included 69 experimental studies that met predefined eligibility criteria, requiring broiler-specific trials with clear reporting of omega-3 source, inclusion level, and measurable outcomes related to growth, immune or antioxidant function, gut morphology, fatty acid composition, or meat quality. Searches were performed in Scopus and Web of Science for peer-reviewed articles published between 2020 and 2025. Across studies, supplementation with fish oil, flaxseed, or algal oil consistently increased the deposition of long-chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in broiler tissues. Omega-3 inclusion improved immune modulation, gut morphology, and antioxidant enzyme activity while reducing inflammatory markers and lipid peroxidation. Meat quality benefits included lower n-6:n-3 ratios by improving tenderness and juiciness and enhanced oxidative stability with no detrimental effects on growth performance. Nevertheless, responses varied with broiler strain, dietary formulation, feeding phase, antioxidant protection, and environmental conditions. As high levels of marine oils remained susceptible to oxidative degradation. Overall, omega-3 supplementation represents a viable and scalable precision-nutrition strategy for enriching poultry meat and supporting broiler health. Future research should prioritize cost-effective algal sources, establish phase-specific inclusion thresholds across genetic lines, and evaluate synergy with natural antioxidants and bioactive compounds to optimize oxidative stability, shelf life, and consumer acceptance.
