Abstract

: The current study was conducted to investigate whether feed coloring red or green, could stimulate pigeons to consume more feed thereby enhancing both productive and reproductive performance. The statistical analysis used in this study was a completely randomized design. A total of 18 adult pairs of pigeons were used at the beginning of the experiment. In this study, the birds used were divided into three experimental basic groups: the control group, the red-colored ration, and then the third group, was fed the green-colored ration. Each treatment had 6 adult pairs for three consecutive nesting cycles. The results indicate that under the condition of this experiment, a significant difference observed in body weight at 4 weeks (BW4) among the experimental groups, with means of 385g for the control group, 406g for the red group, and 355g for the green ration group, Moreover, significant differences were observed in total weight gain, with means of 366, 398, and 341, feed intake with mean values of 90.0, 93.9, and 88.4, and relative feed conversion ratio of 5.72, 4.26, and 5.91 for the control, red-colored ration, and green-colored ration groups, respectively. However, there were no significant effects of red or green rations on egg weight, body weight at hatch, fertility, hatchability, egg-laying cycle, or the period between hatching and the next laying. Based on the results observed from this study, consumption of red-colored food gave better results with regard to productive performance, while there were no effects on reproductive traits in a short time. Further researches are needed to study the effect of more colors in pigeon feeds to determine their impact on both productive and reproductive performance.
一些饲料颜色对鸽子生产和繁殖性能影响的比较研究
:本研究旨在探讨红色或绿色饲料是否能刺激鸽子摄入更多饲料,从而提高生产性能和繁殖性能。本研究采用的统计分析方法是完全随机设计。实验开始时总共使用了 18 对成年鸽。在这项研究中,所使用的鸽子被分为三个实验基本组:对照组、红色饲料组和第三组,第三组喂食绿色饲料。每个处理有 6 对成年鸽,连续三个筑巢周期。结果表明,在本实验条件下,各实验组 4 周体重(BW4)差异显著,对照组平均为 385 克,红色组平均为 406 克,绿色饲料组平均为 355 克。对照组、红色饲料组和绿色饲料组的总增重分别为 366 克、398 克和 341 克,采食量的平均值分别为 90.0 克、93.9 克和 88.4 克,相对饲料转化率分别为 5.72、4.26 和 5.91。然而,红色或绿色日粮对蛋重、孵化时体重、受精率、孵化率、产蛋周期以及孵化到下一次产蛋的间隔期没有明显影响。根据本研究观察到的结果,食用红色饲料对生产性能有更好的效果,而对短时间内的繁殖性状没有影响。需要进一步研究鸽子饲料中更多颜色的影响,以确定其对生产性能和繁殖性能的影响。
