Abstract

A strategy to improve poultry meat production sustainability is the use of by-products from agro-industries, such as cardoon cake (CC). Due to limited literature available, this trial aimed to study the effect of CC as an alternative protein source to soybean meal (SM) or insect meal (black soldier fly, Hermaetia illucens) on broilers' performance, welfare, and meat quality. Eighty day-old chickens were allocated into 4 dietary treatments composed of 5 replicated pens (4 animals per pen): control group (C) fed a basal diet with SM as main protein source; HI15 group fed C with 15% of SM replaced with H. illucens meal; CC15 group fed C with 15% SM replaced with CC; CC20 group fed C with 20% of SM replaced with CC. In the starter period, chicks from CC15 showed similar trends in weight gain (WG), feed intake (FI), and feed conversion ratio (FCR) to the C group; FCR was also comparable to that in HI15, but FI was lower with respect to HI15. In the finisher period, WG in CC15 and CC20 groups did not differ from the C and HI15 groups, but the FCR worsened with respect to C whilst remaining comparable to HI15. The meat fatty acid profile from animals fed CC was rich in oleic acid. Bifidobacterium was detected in the CC20 group only, which also showed significantly lower relative abundance of Bacteroides, Monoglobus, UCG-009, Colidextribacter, and NK4A214_group, and significantly higher relative abundance of Latilactobacillus. These results show that CC can be used for broilers feeding.

Cardoon饼作为一种可持续替代原料在肉鸡饲粮中的应用。
提高禽肉生产可持续性的一项战略是利用农产工业的副产品,如cardoon cake (CC)。由于现有文献有限,本试验旨在研究CC作为豆粕(SM)或昆虫粕(黑兵蝇,hermatia illucens)的替代蛋白质来源对肉鸡生产性能、福利和肉品质的影响。将80日龄鸡分为4个饲粮处理,每组5个重复栏(每个栏4只):对照组(C)饲喂以SM为主要蛋白质来源的基础饲粮;HI15组饲喂C, 15%的SM代之以H. illucens粉;CC15组用CC代替15% SM饲喂C;CC20组投喂C,用20%的SM替代CC,在发育期,CC15组雏鸡的增重(WG)、采食量(FI)和饲料系数(FCR)与C组基本相同;FCR也与HI15相当,但FI相对于HI15较低。在结束期,CC15和CC20组的WG与C和HI15组没有差异,但FCR相对于C恶化,但与HI15保持相当。CC饲养动物的肉脂肪酸谱富含油酸。CC20组仅检出双歧杆菌,其中Bacteroides、Monoglobus、UCG-009、Colidextribacter和NK4A214_group的相对丰度显著低于对照组,Latilactobacillus的相对丰度显著高于对照组。综上所述,CC可用于肉鸡饲养。
