Abstract

BACKGROUND

Animal food shortage and finding efficient ways to produce poultry products are getting more and more important issues in the world.

OBJECTIVES

This study was aimed to determine the effect of replacing corn with pasta wastes (0%, 50% and 100%) in the diet on production performance, some blood variables and the egg quality traits of laying quails.

METHODS

A total of 240 laying quails were allocated into 3 experimental groups with 8 replicates for 8 weeks. Egg production percentage, egg mass, feed intake and also mortality rate and percentage of abnormal eggs, egg quality traits and blood variables were evaluated.

RESULTS

None of the pasta wastes inclusion had significant effect on egg mass, abnormal egg percentage, mortality rate, yolk diameter, yolk weight, albumen height, yolk index, shell weight percentage, egg shape index and blood parameters (except for triglycerides). Replacing 100% corn with pasta by-product reduced feed conversion ratio and increased egg weight values. Replacing 100% corn by pasta wastes significantly increased the albumen weight, shell weight and also egg length and width and decreased the Haugh unit. Replacing 50% and 100% corn had a significant increase in yolk height, egg surface area and significantly decreased shell thickness and yolk colour. Overall, 100% replacement of corn by pasta by-product increased blood triglycerides compared to the 50% group.

CONCLUSIONS

Based on the result of current experiment, total replacement of corn with pasta wastes could increase the egg weight and also improve feed conversion ratio in the laying quail diets.

摘要

背景

动物饲料短缺和寻找有效的方法生产家禽产品在世界范围内变得越来越重要。

目的

本研究旨在确定用面食废料（0%、50%和 100%）替代日粮中的玉米对产蛋鹌鹑生产性能、一些血液变量和蛋品质特性的影响。

方法

将 240 只产蛋鹌鹑分配到 3 个实验组中，每组 8 个重复，持续 8 周。评估蛋产量百分比、蛋重、饲料摄入量以及死亡率和异常蛋的百分比、蛋品质特性和血液变量。

结果

面食废料的添加均未对蛋重、异常蛋百分比、死亡率、蛋黄直径、蛋黄重量、蛋白高度、蛋黄指数、蛋壳重量百分比、蛋形指数和血液参数（除了甘油三酯）产生显著影响。用面食副产品替代 100%的玉米降低了饲料转化率并增加了蛋重值。用面食废料替代 100%的玉米增加了蛋白重量、蛋壳重量以及蛋的长度和宽度，并降低了哈夫单位。用 50%和 100%的玉米替代玉米使蛋黄高度、蛋的表面积显著增加，而蛋壳厚度和蛋黄颜色显著降低。总的来说，与 50%组相比，用面食副产品替代 100%的玉米增加了血液中的甘油三酯。
