Abstract

Background: As the agro-industry produces considerable amounts of by-products globally, it is acknowledged that there is a need to address the environmental issues related to their disposal and the resource competition between food for humans and feed for animals. The aim of this study was to explore, in vitro, the effects of various by-products from the agro-industry on rumen fermentation and methane emission. Samples were collected from various food processing industries, including red and green apple pomace (RAP, GAP), hempseed cake (HC), coffee hulls (CH), coffee grounds (CG), spent mushroom compost (SMC) and distiller's dried grains with solubles (DDGS). In doses of 100, 200 and 300 g kg^-1, the tested by-products were incubated in rumen fluid, where the by-products replaced equal amounts of substrates.

Results: Gas production (GP) and dry matter digestibility (DMD) decreased linearly for most of the tested by-products with the growth of doses (P < 0.001), while NH₃-N concentration increased linearly. Linear decreases were observed in CH₄ production with increasing doses of all by-products (P < 0.05). The reduction of CH₄ production ranged from 21.4% to 33.6% at doses of 100-300 g kg^-1, but reductions were only observed at a dose of 100 g kg^-1 when CH₄ productions were corrected by digested dry matter (P < 0.05). RAP, GAP and HC were higher than CH, CG and SMC for the comparison of key parameters including DMD, GP and volatile fatty acids. Better methane-mitigating effects were observed for RAP, GAP and HC than for the control group and CH, CG and SMC.

Conclusion: Most of the by-products tested were found to be a potential option for replacing conventional feed ingredients but should not exceed a dose at 200 g kg^-1. © 2025 The Author(s).

饲粮中添加农工副产品对体外瘤胃发酵和甲烷产量的量效效应

背景：由于农业工业在全球范围内产生了相当数量的副产品，人们认识到有必要解决与它们的处置以及人类食物和动物饲料之间的资源竞争有关的环境问题。本研究旨在探讨农用工业各种副产物对瘤胃发酵和甲烷排放的影响。样品来自不同的食品加工行业，包括红苹果渣和青苹果渣（RAP， GAP）、大麻籽饼（HC）、咖啡壳（CH）、咖啡渣（CG）、废蘑菇堆肥（SMC）和酒糟干颗粒及可溶物（DDGS）。在100、200和300 g kg-1的剂量下，将测试的副产物在瘤胃液中孵育，其中副产物取代等量的底物。结果：大部分副产物产气量（GP）和干物质消化率（DMD）随剂量的增加呈线性下降，氮磷浓度线性升高。随着所有副产物剂量的增加，甲烷产量呈线性下降（在剂量为100-300 g kg-1时，甲烷产量在21.4%至33.6%之间，但只有在剂量为100 g kg-1时，用消化的干物质校正甲烷产量时，才观察到减少）。结论：大多数测试的副产物被发现是替代传统饲料原料的潜在选择，但不应超过200 g kg-1的剂量。©2025作者。约翰威利父子有限公司代表化学工业协会出版的《食品与农业科学杂志》。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
