Abstract

Coffee is a renowned beverage derived from plants globally. In the coffee production process, coffee pulp is a by-product that is abundant in phenolic compounds. Therefore, this study aimed to assess the effect of coffee pulp extract (CPE) on growth performance, blood biochemistry, intestinal morphology, carcass characteristics, and meat quality of broiler chickens. A total of 160 one-day-old male Ross 308 broilers were randomly allocated to four treatments with five replicates and eight chicks per replicate in a completely randomized design. These four dietary treatments included a basal diet with CPE of 0 (Control), 250 (CPE250), 500 (CPE500), and 1,000 (CPE1000) mg/kg diet for 35 days. The results showed that the body weight (BW) of the CPE500 group was significantly higher (P < 0.01) compared to the other groups at 35 days. Moreover, CPE500 increased the average daily gain (ADG) (P = 0.004) and reduced the feed conversion ratio (FCR) (P = 0.008). No significant differences (P > 0.05) were observed in the blood biochemistry profile. In addition, the investigation on intestinal morphology showed that CPE supplementation enhanced villus height (VH) (P = 0.004), crypt depth (CD) (P < 0.05), and ratio of VH:CD (P < 0.05) in the duodenum. Dietary supplementation with CPE significantly increased the percentage of neck weight (P < 0.05) compared to the control groups. However, no significant effects of CPE supplementation were observed on the meat quality parameters of breast and thigh muscles, including pH, color, water-holding capacity, and tenderness (P > 0.05). A significant increase (P < 0.05) in thigh fat content was observed with CPE supplementation. In conclusion, CPE500 can improve the growth performance and intestinal morphology of broiler chickens despite the presence of antioxidants and anti-inflammatory agents. This suggests that coffee pulp biomass could potentially be used as an alternative feed additive from agricultural biomass in broiler production.

饲粮中添加咖啡浆提取物可提高肉仔鸡的生长性能和肠道形态

咖啡是一种享誉全球的植物原料饮料。在咖啡生产过程中，咖啡果肉是富含酚类化合物的副产品。因此，本试验旨在研究咖啡浆提取物（CPE）对肉鸡生长性能、血液生化、肠道形态、胴体特性和肉品质的影响。试验选用160只1日龄罗斯308肉鸡，采用完全随机设计，随机分为4个处理，每处理5个重复，每个重复8只鸡。4种饲粮处理为基础饲粮，CPE分别为0（对照）、250 （CPE250）、500 （CPE500）和1000 (CPE1000) mg/kg，饲喂35 d。结果表明，CPE500组的体重（BW）显著高于对照组(P <；0.01)，与其他组相比，在35天。CPE500提高了平均日增重（P = 0.004），降低了饲料系数（P = 0.008）。无显著差异(P >；血液生化指标0.05)。此外，肠道形态学调查显示，添加CPE可提高绒毛高度（VH）（P = 0.004）、隐窝深度（CD） (P <；VH:CD比值(P <；0.05)。饲粮中添加CPE显著提高了颈重百分比(P <；0.05)。然而，CPE的补充对胸肌和大腿肌的肉质参数，包括pH值、颜色、保水能力和嫩度没有显著影响(P >；0.05)。显著增长(P <；CPE对大腿脂肪含量的影响为0.05)。综上所述，CPE500在添加抗氧化剂和抗炎剂的情况下仍能改善肉仔鸡的生长性能和肠道形态。这表明咖啡浆生物质有潜力作为一种替代农业生物质的饲料添加剂用于肉鸡生产。

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.
