Meta-Analysis: Effect of Transport Distance on Physiological Conditions, Pre-Slaughter, and Broiler Meat Quality

Meta-analysis study of the effect transportation distance on physiological conditions, pre-slaughter and broiler meat quality was carried out to examine magnitude calculate publication bias quality. The materials obtained from 1123 studies 622 relevant were selected 62 journals for further analysis. Parameters observed related conditions consisted blood glucose levels, corticosterone body temperature. arrival weight loss mortality. Meat parameters percentage drip loss, pH, color. Transportation distances are categorized into various moderator individual combined distances, namely <60 km, 60-180 >180 km (a collection km). data tabulated analyzed using CMA 3.7 software. results showed a negative with moderate level determination (est. 0.3-0.5) strong 0.5-1.0). Publication found in several such as levels color (redness) did not show significant egger's test result (p>0.05), which potentially having an interfere interpretation results. However Rosenthal analysis (p<0.05)) means that intervention change overall data. It concluded had consistency
