在肉鸡中评价了商业有机酸（OA）产品对饲料回收和运输过程中体重损失（BWL）、胴体产量和肉质的影响。在巴西进行了两项实验。将商业房屋配对为接受常规水的对照组和接受水中OA的处理组。在实验1和实验2中，经处理的鸟的BWL分别减少了37 g和32.2 g。在试验2中，未观察到组间胴体产量的差异。成本效益的估计建议使用OA的1：16的比例。在墨西哥进行的试验3中，观察到OA处理的鸡的饮水量、BWL和肉质特性的显著差异（P < 0.05）。这些数据表明，这种OA产品可以通过减少BWL和改善肉质属性来改善家禽业的动物福利和经济问题。
The effect of a commercial organic acid (OA) product on BW loss (BWL) during feed withdrawal and transportation, carcass yield, and meat quality was evaluated in broiler chickens. Two experiments were conducted in Brazil. Commercial houses were paired as control groups receiving regular water and treated groups receiving OA in the water. Treated birds had a reduction in BWL of 37 g in experiment 1 and 32.2 g in experiment 2. In experiment 2, no differences were observed in carcass yield between groups. Estimation of the cost benefit suggested a 1:16 ratio by using the OA. In experiment 3, conducted in Mexico, significant differences on water consumption, BWL, and meat quality characteristics were observed in chickens that were treated with the OA (P < 0.05). These data suggest this OA product may improve animal welfare and economic concerns in the poultry industry by reducing BWL and improving meat quality attributes.
