紫壳蛋品质及孵化率的统计学分析

以400日龄产紫皮蛋的农大3号节粮小型蛋鸡(试验组)、产紫皮蛋的普通褐壳蛋鸡(试验组)与普通的农大3号节粮小型褐壳蛋鸡(对照组)、普通褐壳蛋鸡(对照组)及白来航鸡为研究对象,对其蛋品质及孵化率进行比较。结果表明:同品系的普通紫皮蛋的蛋壳厚度比普通褐壳蛋的厚度高,差异达到极显著水平;同品系的普通紫皮蛋的哈氏单位比普通褐壳蛋的哈氏单位高,差异达显著水平;同品系矮小鸡的紫皮蛋的蛋壳色泽、蛋壳强度、蛋壳厚度及蛋黄色泽与普通褐壳蛋的差异达到极显著;紫皮蛋的蛋白高度与普通褐壳蛋的差异达到显著水平。随着保存时间的延长,紫皮蛋的孵化率高于普通蛋的孵化率。

对紫壳蛋鸡育种前景的分析

本试验材料由北农大种禽有限责任公司提供。试验以400日龄矮小型紫壳蛋鸡(试验组)、普通型紫壳蛋鸡(试验组)与矮小型褐壳蛋鸡(对照组)、普通褐壳蛋鸡(对照组)及白来航鸡为研究对象,对其蛋品质及孵化率进行比较。试验结果表明:同品系的普通紫皮蛋的蛋壳厚度比普通褐壳蛋的厚度厚,差异达到极显著(P<0.01);同品系的普通紫皮蛋的哈氏单位比普通褐壳蛋的哈氏单位高,差异显著(P<0.05);同品系的矮小鸡的紫皮蛋的蛋壳色泽、蛋壳强度、蛋壳厚度及蛋黄色泽与普通褐壳蛋的差异达到极显著(P<0.01):紫皮蛋的蛋白高度与普通褐壳蛋的差异达到极显著(P<0.01)。随着保存时间的延长,紫皮蛋的孵化率高于普通蛋的孵化率;在矮小型紫壳蛋鸡、普通紫壳蛋鸡、矮小型褐壳蛋鸡和普通褐壳蛋鸡均发现蛋壳中的原卟啉和胆绿素的含量正相关。

Some Agronomic and Chemical Traits of Blue Aleurone and Purple Pericarp Wheat （Triticum L.）

Thirteen diverse anthocyanin pigmented wheat genotypes originating from different countries were investigated for agronomic and chemical traits. The results showed significant variation among wheat genotypes in yield and grain physical characteristics, Released cultivars were superior in grain yield, but other genetic resources exceeded the cultivars in regard to test weight, grain mass, or seed plumpness. In case of phytochemical content both genotypic and environmental effects were important for the observed variations. The total phenolic content varied from 120 to 177 mg ferulic acid equivalent per 100 g dry weight; total anthocyanin content from 3.4 to 75.2 ppm cyanidin glucoside equivalent; yellow pigment content from 2.6 and 7.6 ppm beta-carotene equivalent; protein content from 11.3 to 19.1%. The study demonstrated that Ethiopian wheats are a source of high levels of anthocyanins and protein content.
