Acid silage is a convenient method for converting raw poultry wastes (i.e., chicken offal) to fish feed ingredients. To investigate the potentiality of chicken offal for fish feed formulation; combination of two acids were used in the trail (90-days). The proximate compositions of raw offal contained 37.22 % moisture, 37.24 % protein, 18.80 % fat,19.04 % ash and 62.78 % dry matter; ensiled offal contained 25.02 % moisture, 47.31 % protein, 13.79 % fat, 13.45 % ash and 74.98 % dry matter; and post storage offal contained 23.05 % moisture, 44.33 % protein, 13.10 % fat, 12.75 % ash and 76.95 % dry matter. It took 13 days to convert raw offal into final product that was confirmed by physical observation in necked eyes (i.e., raw smell converted into pungent acidic; thick solid form liquefied; raw pink color converted to bright brownish and absence of microorganisms). No significant difference was observed during trail and storage period for all components as moisture, protein, fat, ash and dry matter. The pH value was found to be stable at 1.90 in 90-days storage period. These results suggest that chicken offal could be potentially used for aqua feed formulation that would be a cost effective means for industrial waste management.

将生动物废物转化为鱼饲料配方的方法：使用酸青贮方法进行可持续工业废物管理的案例研究

酸青贮是将生禽禽粪便（即鸡杂）转化为鱼饲料成分的便捷方法。调查鸡内脏制备鱼饲料的潜力；在试验中（90天）使用了两种酸的组合。接近内脏的成分包含37.22％的水分，37.24％的蛋白质，18.80％的脂肪，19.04％的灰分和62.78％的干物质。杂碎的内脏含有25.02％的水分，47.31％的蛋白质，13.79％的脂肪，13.45％的灰分和74.98％的干物质。储存后的内脏含有23.05％的水分，44.33％的蛋白质，13.10％的脂肪，12.75％的灰分和76.95％的干物质。经过颈肉的肉眼观察证实，用了13天的时间将生杂碎转化为最终产品（即，原味转化为刺激性酸性；浓稠的固体液化；原始的粉红色转换为亮褐色并没有微生物）。在追踪和储存期间，所有成分（如水分，蛋白质，脂肪，灰分和干物质）均未观察到显着差异。发现在90天的存储期内pH值稳定在1.90。这些结果表明，鸡杂有可能被用于水产饲料配方，这将是一种经济有效的工业废物管理手段。
