摘要
【目的】旨在研究3个蛋鸭品种及两种笼养模式对蛋鸭鸭蛋品质的影响,以期为蛋鸭养殖企业和消费者提供参考。【方法】将1 080羽90日龄山麻鸭、荆江鸭和绍兴鸭(各品种360羽),随机分成2组,分别采用单笼和双笼模式饲养,300日龄时,分别收集单笼和双笼饲养条件下绍兴鸭、山麻鸭和荆江鸭鸭蛋各30或31枚(总计185枚),进行蛋品质指标测定。【结果】1)荆江鸭(62枚)、山麻鸭(61枚)、绍兴鸭(62枚)的各个指标测定值分别为:蛋重(68.40±4.85、70.42±5.19、71.88±5.04)g,蛋比重(1.085±0.005、1.087±0.005、1.091±0.004),蛋壳厚度(0.289±0.011、0.302±0.009、0.307±0.010)mm,蛋形指数(1.331±0.046、1.326±0.051、1.331±0.058),哈氏单位(87.506±4.078、88.046±4.175、84.776±8.465),蛋黄颜色(8.612±1.679、8.669±2.195、8.577±1.048),蛋黄比率(0.341±0.031、0.345±0.028、0.337±0.024)和蛋壳比率(0.113±0.007、0.111±0.006、0.115±0.009)。绍兴鸭、山麻鸭的蛋重和蛋壳厚度均极显著高于荆江鸭;绍兴鸭的蛋比重极显著高于荆江鸭和山麻鸭,其哈氏单位极显著低于山麻鸭和荆江鸭;荆江鸭的蛋壳比率显著高于山麻鸭,绍兴鸭的蛋壳比率极显著高于山麻鸭;其它指标之间未见显著性差异。2)与单笼饲养模式相比,双笼饲养可以显著增加蛋重,极显著提高蛋比重、蛋壳厚度、蛋形指数和蛋壳比率;而笼养模式对哈氏单位、蛋黄颜色和蛋黄比率无显著影响。3)蛋鸭品种和笼养模式两种因素对蛋重、蛋比重、蛋壳厚度、哈氏单位、蛋黄颜色、蛋黄比率和蛋壳比率的影响均不存在交互效应,对蛋形指数的影响存在显著交互效应。【结论】不同品种蛋鸭蛋品质存在显著差异,各有特色;不同笼养模式会对蛋鸭蛋品质产生影响,双笼饲养模式下鸭蛋品质优于单笼饲养。
[Objective]This study was conducted to research the effects of three laying duck varieties and two cage rearing modes on the quality of eggs,thus providing reference for laying duck breeding enterprises and consumers.[Method]In this study,1 080 Shan Partridge ducks,Jingjiang ducks and Shaoxing ducks(360ducks of each species)were reared in single-cage and double-cage mode respectively.At the age of 300 days,30 or 31eggs(185 eggs in total)of each breeds of ducks rearing in two modes were collected,respectively,and routine egg quality indexes were determined.[Result](1)Egg quality-related indicators of Jingjiang ducks(62),Shan Partridge ducks(61),Shaoxing ducks(62)were Egg weight(68.40±4.85,70.42±5.19,71.88±5.04)g,specific gravity of eggs(1.085±0.005,1.087±0.005,1.091±0.004),eggshell thickness(0.289±0.011,0.302±0.009,0.307±0.010)mm,egg shape index(1.331±0.046,1.326±0.051,1.331±0.058),Haugh unit(87.506±4.078,88.046±4.175,84.776±8.465),yolk color(8.612±1.679,8.669±2.195,8.577±1.048),percentage of yolk(0.341±0.031,0.345±0.028,0.337±0.024)and percentage of eggshell(0.113±0.007,0.111±0.006,0.115±0.009). The egg weight and eggshell thickness of Shaoxing duck and Shan Partridge duck were significantly higher than those of Jingjiang duck;the egg specific gravity of Shaoxing duck was significantly higher than that of Shan Partridge duck and Jingjiang duck,and the Haugh unit of Shaoxing duck was significantly lower than that of Jingjiang duck and Shan Partridge duck;the eggshell ratio of Jingjiang duck was significantly higher than that of Shan Partridge duck,and the ratio of Shaoxing duck was extremely significantly higher than that of Shan Partridge duck.There was no significant difference among other indexes.(2)Compared with single cage mode,double cage mode could significantly increase the egg weight,and extremely significantly enhance the specific gravity of eggs,the eggshell thickness,the egg shape index and eggshell ratio.However,the cage rearing mode had no significant effect on yolk color and percentage of yolk.(3)The breed of egg duck and cage mode had no interaction effect on egg weight,specific gravity of eggs,eggshell thickness,Haugh unit,yolk color,percentage of yolk and percentage of eggshell.However,there was a significant interaction effect on egg shape index.[Conclusion]There are differences in egg quality among different duck breeds,and each has its own characteristics;While different cage rearing modes influences egg quality,double-cage mode is better than singlecage mode.
