Former food products (FFPs) have a great potential to replace conventional feed ingredients. This study aimed to investigate the possibility to partially replace standard ingredients with two different types of FFPs: bakery (FFPs-B) or confectionary (FFPs-C) FFPs and their effects on growth performances, feed digestibility and metabolic status in post-weaning piglets. Thirty-six post-weaning piglets were randomly assigned to three experimental diets ( = 12 per diet) for 42 days: a standard diet (CTR), a diet where 30% of standard ingredients were replaced by confectionary FFPs (FFPs-C) and a diet where 30% of standard ingredients were replaced by bakery FFPs (FFPs-B). Individual body weight and fecal dry matter were measured weekly. Feed intake (FI) was determined daily. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated. Fecal samples were collected daily for three days/week to determine apparent total tract digestibility of dry matter (ATTD). At day 0, 21 and 42, blood samples were collected from all the piglets. No significant differences ( > 0.05) between groups were found in growth performances and metabolic profile. However, ATTD in FFPs-B group was lower ( < 0.05) compared to the CTR group at the end of the experiment. This study confirmed the possibility to formulate homogeneous diets integrated with 30% of both categories of FFPs. Further investigations are needed to clarify the effects of bakery former food products on the digestibility of the diet.
废弃食品（FFPs）具有很大的潜力来替代传统饲料成分。本研究旨在探讨用两种不同类型的废弃食品：烘焙类（FFPs-B）或糖果类（FFPs-C）废弃食品部分替代标准成分的可能性，以及它们对断奶仔猪生长性能、饲料消化率和代谢状态的影响。将36头断奶仔猪随机分为三种实验日粮组（每组12头），为期42天：标准日粮组（CTR）、30%标准成分被糖果类废弃食品替代的日粮组（FFPs-C）和30%标准成分被烘焙类废弃食品替代的日粮组（FFPs-B）。每周测量个体体重和粪便干物质。每天测定采食量（FI）。计算平均日增重（ADG）、平均日采食量（ADFI）和饲料转化率（FCR）。每周三天每天采集粪便样本以测定干物质的表观全肠道消化率（ATTD）。在第0天、21天和42天，从所有仔猪采集血液样本。各组之间在生长性能和代谢指标方面未发现显著差异（P>0.05）。然而，在实验结束时，FFPs-B组的ATTD低于CTR组（P<0.05）。本研究证实了配制含有30%这两类废弃食品的均匀日粮的可能性。需要进一步研究以阐明烘焙类废弃食品对日粮消化率的影响。
