Abstract

OBJECTIVE

The aim of the study was to evaluate the physicochemical properties (nutrient composition, pH, water content and activity, sorption properties) and mechanical properties (compression force and energy) of granulated feed mixtures with various inclusion levels of crude fibre concentrates ARBOCEL and VITACEL for broiler chickens, i.e. +0.0% (control group - group C), +0.3%, +0.8%, +1.0%, +1.2%.

METHODS

The feed mixtures were analyzed for their physicochemical properties (nutrient composition by near-infrared spectroscopy, pH with the use a CP-401 pH meter with an IJ-44C glass electrode, water content was determined with the drying method and activity was determined with the Aqua Lab Series 3, sorption properties was determined with the static method) and mechanical properties (compression force and energy with the use TAHD plus texture analyzer). The Guggenheim-Anderson-de Boer (GAB) model applied in the study correctly described the sorption properties of the analyzed feed mixtures in terms of water activity.

RESULTS

The fibre concentrate type affected the specific surface area of the adsorbent and equilibrium water content in the GAB monolayer (p≤0.05) (significantly statistical). The type and dose of the fibre concentrate influenced the dimensionless C and k parameters of the GAB model related to the properties of the monolayer and multilayers, respectively (p≤0.05). They also affected the pH value of the analyzed feed mixtures (p≤0.05). In addition, crude fibre type influenced water activity (p≤0.05) as well as compression energy (J) and compression force (N) (p≤0.001) (highly significantly statistical) of the feed mixtures.

CONCLUSION

The physicochemical analyses of feed mixtures with various inclusion levels (0.3%, 0.8%, 1.0%, 1.2%) of crude fiber concentrates ARBOCEL or VITACEL demonstrated that both crude fiber types may be used in the feed industry as a feedstuff material to produce starter type mixtures for broiler chickens.

摘要

目的

本研究旨在评估添加不同水平粗纤维浓缩物ARBOCEL和VITACEL的肉鸡颗粒饲料混合物的物理化学性质（营养成分、pH值、水分含量和活性、吸附特性）和机械性质（压缩力和能量），即添加水平为+0.0%（对照组 - C组）、+0.3%、+0.8%、+1.0%、+1.2%。

方法

对饲料混合物进行物理化学性质分析（通过近红外光谱法分析营养成分，使用配备IJ - 44C玻璃电极的CP - 401 pH计测定pH值，采用干燥法测定水分含量，使用Aqua Lab Series 3测定活性，采用静态法测定吸附特性）和机械性质分析（使用TAHD plus质构分析仪测定压缩力和能量）。研究中应用的 Guggenheim - Anderson - de Boer（GAB）模型在水分活度方面正确描述了所分析饲料混合物的吸附特性。

结果

纤维浓缩物类型影响吸附剂的比表面积和GAB单层中的平衡水分含量（p≤0.05）（具有显著统计学意义）。纤维浓缩物的类型和剂量分别影响与单层和多层性质相关的GAB模型的无量纲C和k参数（p≤0.05）。它们还影响所分析饲料混合物的pH值（p≤0.05）。此外，粗纤维类型影响饲料混合物的水分活度（p≤0.05）以及压缩能量（J）和压缩力（N）（p≤0.001）（具有高度显著统计学意义）。
