研究了维生素不同添加量对红腿鹧鸪繁殖性能的影响 .研究表明 :维生素添加量的提高 ,可以提高鹧鸪的受精率和入孵蛋出雏率 ,但对产蛋率和平均蛋重影响不大 .
Three groups of breeding partridge were used to study the effects of vitamin levels (150g/t, 300g/t and 450g/t ) on reproductive performance.The rate of fertilization (RF) of each group was 81.0%, 87.08%, and 89.65% respectively, the corresponding intensities of laying (IL) 50.8%, 51.0%, and 51.3%. Average egg weights (AEW) were 22.10g, 22.30g, and 22.50g, respectively. The hatching rates (HR) were 68.4%, 73.7% and 75.7%, respectively. The results indicated that increasing vitamin levels improved rate of fertilization of partridge.
