Abstract
This meta-analysis aimed to evaluate the inclusion of pellet binders on pellet quality and broiler performance, including growth metrics and organ development. A total of 130 data points acquired from 21 published articles were used as a database for determining the effectiveness of pellet binders on pellet quality, performance, and health of broilers. The Hedges’d value was employed as a measure of effect size (ES) in the present meta-analysis. The data were analyzed using a random effects model in OpenMEE software. The addition of pellet binders significantly increased the pellet durability index (PDI), pellet hardness, and moisture content (p<0.05). However, the meta-analysis results suggest that broiler performance, including feed intake, body weight, and FCR, as well as broiler carcass yield, including total carcass, breast, and thighs, were not impacted (p>0.05). In addition, pellet binders did not significantly affect (p>0.05) the relative organ weights, including the gizzard, heart, duodenum, jejunum, and ileum. However, liver weight was significantly different (P<0.01). The meta-analysis showed that pellet binders improved feed quality metrics such as pellet durability, hardness, and moisture, but did not impact broiler performance metrics, including feed intake, body weight, FCR, carcass yield, or other organ weights. Overall, pellet binders did not enhance efficiency in broiler production.
