Abstract

OBJECTIVE

This study aimed to explore the effects of different types of xanthophyll extracted from marigold on the growth performance, skin color, and carcass pigmentation.

METHODS

A total of 192 healthy 60-day-old yellow-feathered broilers weighing an average of 1,279±81 g were randomly allocated to 4 groups, each with 6 replicates and 8 broilers. The 4 treatments were as follows: i) CON group, fed with basal diet; ii) LTN group, supplemented with lutein; iii) MDP group, supplemented with monohydroxyl pigment including dehydrated lutein, β-cryptoxanthin, and α-cryptoxanthin; iv) LTN+MDP group, supplemented with lutein and monohydroxyl pigment in proportion to 1:1. The supplementary content of LTN, MDP, and LTN+MDP was 2 g/kg. Skin color was measured after 7, 14, 21, and 28 days of feeding the dietary treatments. The breast, thigh, and abdominal fat of slaughtered chickens were stored in cold storage at 4°C for 24 hours and then the meat color of lightness (L*), redness (a*), and yellowness (b*) values was determined.

RESULTS

The results showed that all treatments enhanced the yellow scores of subwing skin on day 14, 21, and 28 (p<0.05), and the mixture of lutein and monohydroxyl pigment promoted the yellow scores of shanks on day 14, 21, and 28 (p<0.05). The mixture of lutein and monohydroxyl pigment increased the yellow scores of beaks and all treatments enhanced the yellow of shanks on day 28 (p<0.05). In addition, all treatments improved the yellow (b*) values of breast and thigh muscle, moreover, the monohydroxyl pigment and the mixture of lutein and monohydroxyl pigment enhanced the values of redness (a*) and yellow (b*) of abdominal fat (p<0.05).

CONCLUSION

In summary, different types of xanthophyll extracted from marigold significantly increased the yellow scores of skin color and the yellow (b*) values of carcass pigmentation. Especially, the mixture of lutein and monohydroxyl pigment was more efficient on skin color.

摘要

目的

本研究旨在探讨从万寿菊中提取的不同类型叶黄素对生长性能、皮肤颜色和胴体色素沉着的影响。

方法

将192只60日龄、平均体重为1279±81克的健康黄羽肉鸡随机分为4组，每组6个重复，每个重复8只鸡。4种处理如下：i）对照组，饲喂基础日粮；ii）叶黄素组，添加叶黄素；iii）单羟基色素组，添加包括脱水叶黄素、β-隐黄质和α-隐黄质的单羟基色素；iv）叶黄素+单羟基色素组，按1:1比例添加叶黄素和单羟基色素。叶黄素、单羟基色素和叶黄素+单羟基色素的添加量均为2克/千克。在饲喂日粮处理7、14、21和28天后测量皮肤颜色。将屠宰鸡的胸肉、大腿和腹部脂肪在4°C冷藏24小时，然后测定肉色的亮度（L*）、红色度（a*）和黄度（b*）值。

结果

结果表明，所有处理均提高了第14、21和28天翅下皮肤的黄色评分（p<0.05），叶黄素和单羟基色素混合物提高了第14、21和28天胫部的黄色评分（p<0.05）。叶黄素和单羟基色素混合物提高了喙部的黄色评分，所有处理均提高了第28天胫部的黄色度（p<0.05）。此外，所有处理均提高了胸肌和大腿肌肉的黄度（b*）值，而且，单羟基色素以及叶黄素和单羟基色素混合物提高了腹部脂肪的红色度（a*）和黄度（b*）值（p<0.05）。
