Abstract

This study was carried out to determine the effect of dietary flaxseed meal (FSM) supplemented with dried tomato pomace (DTP) and dried grape pomace (DGP) on performance, egg quality, biochemical parameters traits and antioxidant status of laying hens. Birds (1825 ± 87 g of body weight) were divided into 12 dietary groups with six replicates per group (eight birds per replicate), under a completely randomized design with factorial arrangement 2 × 3 × 2 consisted of two levels of DTP (0 and 15%), three FSM levels (0, 4 and 8%) and two levels of DGP (0 and 5%). As a result of this study, there were no significant differences in egg production and weight as well in feed conversion ratio (FCR) among treatments (p > 0.05). Feeding of DGP reduced significantly feed intake and egg mass when compared to control group (p < 0.05). There was no effect (p > 0.05) of dietary treatment on shell thickness and strength, shape index, Haugh unit and egg specific gravity. Hens consuming 15% DTP and 5% DGP revealed a significantly higher yolk color compared to the other dietary treatments (p < 0.05). Moreover, there was no difference among dietary treatments in terms of serum low-density lipoprotein cholesterol (LDL) and high-density lipoprotein cholesterol (HDL) cholesterol, atherogenic index, triglycerides, total cholesterol levels (p > 0.05). Serum antioxidant parameters as glutathione peroxidase (GSH-Px) activity, malondialdehyde (MDA), total superoxide dismutase (TSOD) and total antioxidant capacity (T-AOC) were not influenced by treatments (p > 0.05). Based on findings, FSM and DTP supplements did not significantly impact most of hens’ performance indicators and egg quality parameters, whereas significant improvements were observed by feeding of 15% DTP and 5% DGP on egg traits, in particular on egg-yolk color that plays a key-role in consumer’s choice. However, the supplementation of FSM and DTP or DGP even in laying hen diet is still controversial and further research is needed.

亚麻籽粕添加干番茄和葡萄渣对蛋鸡生产性能和抗氧化状态的影响

摘要

本研究旨在确定日粮亚麻籽粕 (FSM) 添加干番茄果渣 (DTP) 和干葡萄渣 (DGP) 对蛋鸡生产性能、蛋品质、生化参数特性和抗氧化状态的影响。家禽(体重 1825 ± 87 g)被分成 12 个饮食组,每组重复 6 次(每次重复 8 只鸡),采用完全随机化设计,阶乘排列 2 × 3 × 2 由两个水平的 DTP(0 和15%)、三个 FSM 级别(0、4 和 8%)和两个 DGP 级别(0 和 5%)。作为这项研究的结果,处理之间的产蛋量和重量以及饲料转化率 (FCR) 没有显着差异 ( p > 0.05)。与对照组相比,DGP 的饲喂显着降低了采食量和蛋量 ( p  < 0.05)。 日粮处理对蛋壳厚度和强度、形状指数、哈夫单位和鸡蛋比重没有影响(p > 0.05)。与其他日粮处理相比,食用 15% DTP 和 5% DGP 的母鸡蛋黄颜色显着更高 ( p  < 0.05)。此外,在血清低密度脂蛋白胆固醇 (LDL) 和高密度脂蛋白胆固醇 (HDL) 胆固醇、动脉粥样硬化指数、甘油三酯、总胆固醇水平方面,饮食治疗没有差异(p > 0.05)。血清抗氧化参数如谷胱甘肽过氧化物酶 (GSH-Px) 活性、丙二醛 (MDA)、总超氧化物歧化酶 (TSOD) 和总抗氧化能力 (T-AOC) 不受处理的影响 ( p  > 0.05)。根据研究结果,FSM 和 DTP 补充剂对大多数母鸡的生产性能指标和鸡蛋质量参数没有显着影响,而通过饲喂 15% DTP 和 5% DGP 可显着改善鸡蛋性状,尤其是蛋黄颜色对消费者的选择起着关键作用。然而,即使在蛋鸡日粮中添加 FSM 和 DTP 或 DGP 仍存在争议,需要进一步研究。
