The aim of this experiment was to evaluate the effects of dietary supplementation of stinging nettle powder (SNP) on laying performance, egg quality, and some selected serum biochemical parameters of quails. One hundred and forty-four 10-wk-old Japanese quails (initial body weight = 199 ± 18 g) were divided into 3 dietary treatment groups (basic diet without SNP [SNP0], SNP0 with 3% SNP [SNP3], SNP0 with 6% SNP [SNP6]) with 4 replicates of 12 quails for a rearing period of 12 wk. At 22 wk of age, the final body weights of the SNP3 and SNP6 groups were significantly ( = 0.001) reduced compared to that of the SNP0 group. Daily feed intake was not statistically different among the groups. The mean number of eggs laid ranged from 65 to 69 with laying rates from 76.8% to 82.1%. The percentage of cracked eggs was not significantly different among the groups and ranged from 1.6% to 1.9%. The egg weight was similar and the feed conversion ratio was closer among the groups. The egg yolk cholesterol, serum cholesterol and serum triglyceride levels in the SNP6 group were significantly reduced ( < 0.001) compared to those of the SNP0 group. Serum Ca, P and Mg were not significantly influenced by the supplementation. In conclusion, the results demonstrated that the supplementation of SNP to the quail diet at the level of 6% reduced quail egg yolk cholesterol, serum total cholesterol and serum triglyceride levels and did not negatively influence quail performance.
本实验旨在评估日粮中添加荨麻粉(SNP)对鹌鹑产蛋性能、蛋品质以及部分选定血清生化指标的影响。144只10周龄日本鹌鹑(初始体重=199±18克)被分为3个日粮处理组(不添加SNP的基础日粮[SNP0]、添加3% SNP的SNP0 [SNP3]、添加6% SNP的SNP0 [SNP6]),每组4个重复,每个重复12只鹌鹑,饲养期为12周。在22周龄时,SNP3组和SNP6组的最终体重与SNP0组相比显著降低(P=0.001)。各组间的日采食量无统计学差异。平均产蛋数在65至69枚之间,产蛋率在76.8%至82.1%之间。各组间破蛋率无显著差异,范围在1.6%至1.9%之间。蛋重相似,各组间的饲料转化率相近。与SNP0组相比,SNP6组的蛋黄胆固醇、血清胆固醇和血清甘油三酯水平显著降低(P<0.001)。血清钙、磷和镁不受添加物的显著影响。总之,结果表明,在鹌鹑日粮中添加6%的SNP可降低鹌鹑蛋黄胆固醇、血清总胆固醇和血清甘油三酯水平,且对鹌鹑性能无负面影响。
