By-products from fruit industrialization retain nutritional and functional components; thus, they may find use in animal feeding. This study aimed to assess the effects of dietary fruit industrial by-products on the tilapias blood biochemical and oxidative parameters and on the composition and lipid peroxidation of their fillets. Four diets were supplied to the tilapias: a C-control diet, with no fruit meal, and three diets containing 5% of either acerola (ACM), apple (APM) or grape (GRM) meal. The phenolic compounds and the carotenoids in the meals and their antioxidant capacities were measured. Fish were weighed and measured for the calculation of the growth performance data, their blood was analyzed for health and oxidative status biomarkers and their fillets were analyzed for proximal composition and lipid peroxidation. Grape meal had the highest concentration of phenolics and carotenoids and the highest antioxidant activity, followed by acerola and apple meals. The productive performance was similar among the treatments. The fruit by-product diets either maintained or improved the biochemical biomarkers of health and improved the oxidative status of the fish. The fruit by-product diets increased the concentration of lipids in the fillets and slowed down the onset of the lipid peroxidation during frozen storage.
水果产业化的副产品保留了营养和功能成分；因此，它们可用于动物饲料。本研究旨在评估日粮中水果工业副产品对罗非鱼血液生化和氧化参数以及鱼片组成和脂质过氧化的影响。给罗非鱼提供了四种日粮：一种C-对照日粮，不含果粕，以及三种分别含有5%针叶樱桃（ACM）、苹果（APM）或葡萄（GRM）粕的日粮。测定了粕中的酚类化合物和类胡萝卜素及其抗氧化能力。对鱼进行称重和测量以计算生长性能数据，分析其血液中的健康和氧化状态生物标志物，并分析其鱼片的近端组成和脂质过氧化。葡萄粕的酚类和类胡萝卜素浓度最高，抗氧化活性也最高，其次是针叶樱桃粕和苹果粕。各处理间生产性能相似。水果副产品日粮要么维持或改善了健康的生化生物标志物，要么改善了鱼的氧化状态。水果副产品日粮增加了鱼片中脂质的浓度，并减缓了冷冻储存期间脂质过氧化的发生。
