摘要

在这项研究中,我们考察了糙米和酒糟(国产饲料原料)能否替代肉鸡饲料中的玉米和豆粕(主要进口饲料原料)。在实验 1 中,21 日龄的肉用仔鸡被分为两组,分别饲喂以玉米-大豆或糙米-大豆为基础的日粮三周(3 只鸡 × 4 个重复/组)。糙米显著提高了体重增加和饲料转化率。饲喂糙米还能显著提高大腿的L*(亮度),显著降低大腿的a*(红度)和b*(黄度)以及脂肪的b*。在实验 2 中,将 21 日龄的肉用仔鸡分为三组,分别饲喂玉米-大豆日粮 3 周、饲喂玉米-大豆日粮 2 周后饲喂糙米酒糟日粮 3 周或饲喂糙米酒糟日粮 3 周(3 只鸡×4 个重复/组)。替代进口饲料原料明显提高了饲料转化率。饲喂糙米和清酒酒糟 3 周后,胸肉、大腿肉和脂肪的 a* 值以及大腿肉和脂肪的 b* 值明显下降。喂食糙米和清酒酒糟 1 周后,乳房和脂肪的 a* 值明显降低。这些结果表明,糙米和日本酒糟可用于替代肉鸡的进口饲料原料,如玉米和豆粕,而不会对生长性能产生不利影响。这些国产饲料原料可能有利于日本当地家禽的生产和消费。

Effects of Dietary Brown Rice and Sake Lees on the Growth Performance and Color of Meat in Broiler Chicks.

In this study, we examined whether brown rice and sake lees (domestic feed ingredients) could replace corn and soybean meal (major imported feed ingredients) in broiler chick feed. In Experiment 1, 21-day-old broiler chicks were assigned to two groups and fed a corn-soybean- or a brown rice-soybean-based diet for three weeks (3 birds × 4 replicates/group). Dietary brown rice significantly improved body weight gain and feed conversion ratio. Brown rice feeding also significantly increased L* (lightness) in the thigh and significantly decreased a* (redness) and b* (yellowness) in the thigh and b* in the fat. In Experiment 2, 21-day-old broiler chicks were assigned to three groups and fed either a corn-soybean-based diet for 3 weeks, a corn-soybean-based diet for the first 2 weeks followed by a brown rice sake lees-based diet for the last week, or a brown rice sake lees-based diet for 3 weeks (3 birds × 4 replicates/group). Replacement of the imported feed ingredients significantly improved the feed conversion ratio. The a* values for the breast, thigh, and fat, and the b* values for the thigh and fat were significantly decreased by rice and sake lees feeding for 3 weeks. The a* values for the breasts and fat were significantly decreased by rice and sake lees feeding for 1 week. These results suggest that brown rice and sake lees can be used as replacements for imported feed ingredients such as corn and soybean meal in broiler chicks without detrimental effects on growth performance. These domestic feed ingredients may benefit local production and consumption of poultry in Japan.
