摘要
为比较不同品系鸭及其杂交组合的蛋品质差异,从绍兴鸭、缙云麻鸭、山麻鸭、绍兴鸭×缙云麻鸭和山麻鸭×缙云麻鸭共5个品种(组合)选育出的5个青壳系为研究对象,每个品系随机抽取青壳蛋各30枚,进行蛋品质测定和相关性分析。结果表明:各品系蛋形指数无显著差异(P>0.05),均符合蛋形标准;绍兴鸭×缙云麻鸭的蛋壳厚度最大,与绍兴鸭、山麻鸭、山麻鸭×缙云麻鸭3个品系差异显著(P<0.05);绍兴鸭×缙云麻鸭和山麻鸭的蛋壳强度最大,与绍兴鸭差异显著(P>0.05);绍兴鸭的蛋重最大,显著高于其他品系(P<0.05);蛋白高度绍兴鸭×缙云麻鸭最高,与其他品系差异显著(P<0.05);缙云麻鸭的哈夫单位数值最大,绍兴鸭最小,差异显著(P<0.05)。总体上看,绍兴鸭×缙云麻鸭蛋壳厚度、蛋壳强度和蛋白高度均为最佳,而绍兴鸭的蛋重最大。蛋品质各性状相关分析发现:蛋壳厚度与蛋壳强度呈极显著正相关(P<0.01);哈夫单位与平均蛋重呈负相关(P<0.05),与蛋白高度强正相关(P<0.01)。
Taking Shanxing duck （SX）, Jinyun Ma duck （JM）, Shanma duck （SM）, SX × JM and SM × JM as study objects, egg quality among the different laying ducks and their hybridized combinations were compared. Each strain sampled 30 green-shell eggs randomly. The result showed ： all egg shape index of strains showed no significant difference and were up to the standard; shell thickness were the highest in SX x JM green shell eggs, which was significantly different from SX, SM, and SM x JM （ P 〈 0. 05 ） ; shell intensity in SX x JM and SM was the biggest and sig- nificantly different from SX （P 〈 0.05 ） ; Egg weight in SX was the highest and significantly different from other breeds （ P 〈 0. 05 ） ; albumen height in SX ~ JM was the highest and significantly different from other breeds （ P 〈 0. 05 ） ; Hough unit in JM were the highest, and significantly different from SX in which Hough unit were the lowest （P 〈 0. 05）. In total, SX x JM were best in shell thickness, shell strength and albumen height, while egg weight was biggest in SX. Correlation analysis showed a very significantly positive correlation between shell thickness and shell intensity （P 〈 0. 01 ） ; and that Hough unit was negative correlated with egg weight （P 〈 0. 05 ）, and very signifi- cantly positive correlated with albumen height （P 〈 0. 01 ）.
