Abstract

BACKGROUND

A prebiotic is defined as an indigestible feed substance that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the large intestine, thereby improving host health and products.

OBJECTIVES

This study was conducted to determine the effects of supplementing prebiotic fructooligosaccharide (FOS) to the diets of Hy-Line W-36 laying hens.

METHODS

A total of 168 Hy-Line W-36 laying hens were allocated to four dietary levels of FOS (0, 1.0, 2.0, 3.0 g/kg diet), 6 replicates of 7 birds each during 63-74. The experiment was performed using a completely randomized design.

RESULTS

Productive performance was not significantly affected by the FOS supplementation. Body weight gain was linearly decreased with increasing FOS levels in the diet (p < 0.01). However, eggshell strength, shell thickness and Ca and p percentages were not significantly affected, as were anti-sheep red blood cell titres, blood parameters and blood metabolites. In the first period of the experiment (63-65 weeks), shape index and Haugh unit at the dose of 3.0 g/kg FOS were significantly increased and decreased in comparison with control, respectively (p < 0.05). In the third and fourth periods (69-71 and 72-74 weeks of age), the FOS had no significant effect on the internal egg quality traits. Furthermore, FOS had a linear decrease in the most saturated fatty acids (SFAs), including myristic, palmitic, margaric and stearic fatty acids; some of the mono-un-SFA (MUFA; palmitoleic and ginkgolic acids), and poly-unsaturated fatty acids (γ-linolenic and eicosatrienoic).

CONCLUSIONS

Supplementing different levels of FOS to the diet of commercial laying hens had no significant effect on the layers' performance, immune response and blood parameters, whereas there was a significant effect on some of the internal egg quality traits and egg yolk fatty acid contents.

摘要

背景

益生元被定义为一种不可消化的饲料物质，通过选择性地刺激大肠中一种或有限数量的细菌的生长和/或活性，从而改善宿主健康和产品，对宿主有益。

目的

本研究旨在确定在 Hy-Line W-36 产蛋鸡日粮中添加益生元果寡糖（FOS）的效果。

方法

将 168 只 Hy-Line W-36 产蛋鸡分配到 FOS 的四种日粮水平（0、1.0、2.0、3.0 g/kg 日粮），每组 6 个重复，每个重复 7 只鸡，共 63-74 天。试验采用完全随机设计。

结果

FOS 补充对生产性能没有显著影响。随着日粮中 FOS 水平的增加，体重增加呈线性下降（p<0.01）。然而，蛋壳强度、蛋壳厚度以及 Ca 和 p 百分率没有显著影响，绵羊红细胞抗血清效价、血液参数和血液代谢物也没有显著影响。在试验的第一阶段（63-65 周），3.0 g/kg FOS 组的形状指数和哈夫单位显著增加和降低，与对照组相比分别为（p<0.05）。在第三和第四阶段（69-71 周和 72-74 周龄），FOS 对内质蛋品质特性没有显著影响。此外，FOS 对内质蛋中最饱和脂肪酸（SFAs），包括肉豆蔻酸、棕榈酸、硬脂酸和花生四烯酸，一些单不饱和脂肪酸（MUFA；棕榈油酸和银杏酸）和多不饱和脂肪酸（γ-亚麻酸和二十碳三烯酸）有线性下降。
