摘要:
为研究不同饲养密度条件下两层两列式网床养殖模式对樱桃谷肉鸭生产性能与血清生化指标的影响,选取2 400羽健康、体质量相近的樱桃谷肉鸭,随机分为3组,分别为传统地面平养组(5羽/m2)、低密度(5羽/m2)或高密度(7羽/m2)两层两列式网床养殖组,每组4个重复。结果表明:地面平养组与低密度两层两列式网床养殖组肉鸭43日龄出栏质量最优,分别为3.05、3.06 kg,高密度两层两列式网床养殖组仅为2.76 kg;36~42日龄期间,日平均采食量由高至低依次为地面平养组、低密度两层两列式网床养殖组、高密度两层两列式网床养殖组,且差异显著(P<0.05);高密度两层两列式网床养殖组料质量比为2.11,显著高于地面平养组的1.85与低密度两层两列式网床养殖组的1.83(P<0.05);各处理组肉鸭成活率均在97%~98%。此外,低密度两层两列式网床养殖组鸭血清尿素氮与促肾上腺皮质激素浓度分别为 0.7 mmol/L 与31.2 ng/L,分别显著低于高密度组的1.2 mmol/L与36.5 ng/L(P<0.05),而与传统地面平养组无显著差异(P>0.05)。研究结果揭示适度养殖密度条件下两层两列式网床养殖模式对肉鸭生产性能与血清生化指标无负面影响,且较传统地面饲养更适宜规模化与集约化生产。
