Abstract

For a transformation of the global food system towards sustainability, circular approaches and nutrient-rich side-stream valorization are mandatory. Moreover, affordable and sustainable alternatives to corn, soy, and fish meal are needed in poultry production. Recently, insects and their derived products have gained research interest as alternative sources of conventional feed ingredients in poultry nutrition. The Mediterranean fruit fly (medfly; Ceratitis capitata) production industry using sterile insect technology amasses thousands tonnes of rearing residues annually. This study is the first to shed light on the potential use of medfly rearing residues (MFRR), as a partial replacement for corn and soybean in Gimmizah chicks’ diets, with or without biological supplementation (BS). It evaluates their effects on growth, carcass characteristics, blood indices, serum biochemical and histological changes in internal organs. A 7-week trial was conducted using 240, 15-day-old Gimmizah chicks, which were randomly divided into four groups (6 replicates, 10 birds each): the first group (T1) was fed a corn-soybean control diet, the 2nd group (T2) fed the control diet enriched with 1 ml BS/kg diet. The 3rdgroup (T3) received the control diet after replacing 10 % of corn and soybean with MFRR meal, while the 4th group (T4) fed the 10 % replacement by MFRR combined with 1 ml of BS. All groups received isoenergetic and isoprotienic diets with free access to feed and water for 49 days trial period. Compared to the control, both BS and MFRR inclusion with or without BS (T4 and T3, respectively) positively improved body weight, feed consumption, feed conversion, performance index and carcass yield. Blood analysis showed increased red blood cells, hemoglobin, packed cell volume, total protein, albumin, globulins, triglycerides, cholesterol, thyroxine hormone, uric acid and creatinine, with no adverse histological alteration in the bursa or intestine. In conclusion, the study suggests that MFRR can effectively replace 10 % of traditional feed ingredients, with or without BS, enhancing chicks' performance and health. Further future studies are recommended for broader application of MFRR in poultry nutrition.

地中海果蝇饲养残余物及生物补充对鸡仔鸡生产性能的影响

为了使全球粮食系统向可持续性转变，循环方法和营养丰富的侧流增值是强制性的。此外，家禽生产需要玉米、大豆和鱼粉的可负担和可持续替代品。近年来，昆虫及其衍生产品作为家禽营养中传统饲料成分的替代来源已引起人们的研究兴趣。地中海果蝇；使用昆虫不育技术的生产工业每年积累数千吨饲养残留物。本研究首次阐明了在添加或不添加生物添加剂（BS）的情况下，稻蝇养殖残留物（MFRR）作为鸡粮中玉米和大豆的部分替代品的潜在用途。评价其对生长、胴体特性、血液指标、血清生化及内脏组织变化的影响。试验选用240只15日龄的吉美沙雏鸡，随机分为4组（6个重复，每组10只）：第一组（T1）饲喂玉米-大豆对照饲粮，第二组（T2）饲喂添加1 ml BS/kg饲粮的对照饲粮。第3组（T3）饲喂MFRR替代10%玉米和大豆的对照饲粮，第4组（T4）饲喂MFRR替代10%玉米和大豆的饲粮，并添加1 ml BS。各组均饲喂等能、等蛋白质日粮，试验期49 d。与对照组相比，添加或不添加BS和MFRR（分别为T4和T3）均显著提高了体重、饲料消耗、饲料系数、生产性能指标和胴体产量。血液分析显示红细胞、血红蛋白、堆积细胞体积、总蛋白、白蛋白、球蛋白、甘油三酯、胆固醇、甲状腺激素、尿酸和肌酐增加，在滑囊或肠道中没有不良的组织学改变。综上所述，无论是否添加BS， MFRR均可有效替代10%的传统饲料成分，提高雏鸡生产性能和健康水平。建议开展进一步的研究，以扩大MFRR在家禽营养中的应用。

期刊介绍： First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
