摘要:

旨在探究脂肪沉积量对产蛋后期繁殖性能的影响,为提高种鸡繁殖效率提供基础。选择65只43周龄健康北京油鸡,测定43~65周龄产蛋数,分别在53和63周龄进行孵化性能和蛋品质的测定,根据65周龄腹脂率分为高腹脂组、中等腹脂组和低腹脂组,统计分析3组产蛋数、蛋品质和种蛋孵化性能的差异。结果显示,中等腹脂组产蛋数比高腹脂组高17.02%,比低腹脂组高8.29%;中等腹脂组受精蛋孵化率比高腹脂组高4.70%,比低腹脂组高10.10%,中等腹脂组入孵蛋孵化率比高腹脂组高6.98%,比低腹脂组高10.47%;3组间蛋重、蛋黄重、蛋壳强度和蛋壳厚度无显著差异(P>0.05),而高腹脂组蛋形指数显著高于低腹脂组(P=0.05)。综上表明,采取适当措施控制母鸡脂肪沉积量利于后期产蛋性能、蛋形和孵化性能的维持。

Abstract:

This study investigated the effects of fat deposition on reproductive performance of Beijing-You chickens during the late stage of reproductive period, aiming at providing data support to increase the reproduction efficiency. A total of 65 Beijing-You chickens of 43 weeks of age were selected. The daily egg production was recorded. The incubation performance and egg quality estimation were performed at 53 and 63 weeks of age, respectively. The animals were divided into high, medium and low abdominal fat content groups based on their abdominal fat yield estimated at 65 weeks of age, and the difference of egg number,egg quality and hatchability of egg were analyzed among different groups. The medium abdominal fat yield group produced 17.02% and 8.29% more eggs than the high and low groups, respectively. The hatchability of fertile eggs of the medium abdominal fat yield group was 4.70% and 10.10% higher than that of the high and low groups, respectively. Similarly, the hatchability of setting eggs of the medium abdominal fat yield group was 6.98% and 10.47% higher than that of the high and low groups, respectively. No significant difference on egg weight, yolk weight, shell strength and shell thickness were observed (P>0.05). The egg shape index of the high abdominal fat yield group was significantly higher than that of low group (P=0.05). The results suggested that manners should be taken to regulate the fat deposition during the late stage of reproductive period to gain better egg production, egg quality, and hatchability.
