摘　　要：试验旨在研究饮水饲喂乳酸菌(植物乳杆菌)制剂对商品蛋鸡产蛋后期生产性能、蛋品质、鸡蛋中矿物质含量、抗氧化能力指标的影响。选择81周龄的健康蛋鸡1125只,分为3组,每组5个重复,每个重复75只,对照组、试验Ⅰ组和试验Ⅱ组在饲喂相同日粮条件下饮水饲喂0、3、5 mL/(只·d)剂量的乳酸菌制剂(活菌数≥1.0×10^(9)CFU/mL)。预试期为7 d,正试期为44 d。结果表明:(1)生产性能:试验Ⅰ组和试验Ⅱ组与对照组相比平均蛋重显著提高(P<0.05),试验Ⅱ组产蛋率显著提高(P<0.05);2个试验组料蛋比、破蛋率有改善的趋势,但无显著差异(P>0.05);(2)蛋品质:试验Ⅱ组与对照组相比蛋壳强度(P<0.05)和蛋壳厚度显著提高(P<0.05);蛋壳厚度、哈夫单位、蛋白高度等指标差异不显著(P>0.05);(3)鸡蛋中矿物质元素含量:试验Ⅰ组和试验Ⅱ组与对照组相比鸡蛋中镁元素含量(P<0.05)和锌元素含量显著提高(P<0.05),试验Ⅱ组钙元素含量显著提高(P<0.05),其他矿物质元素无显著差异(P>0.05);(4)抗氧化能力:试验Ⅰ组和试验Ⅱ组与对照组相比总抗氧化能力显著提高(P<0.05),其他指标无显著差异(P>0.05)。综上所述,饮水饲喂植物乳杆菌制剂可提高81周龄蛋鸡生产性能、蛋品质和抗氧化能力,建议添加剂量为5 mL/(只·d)。The aim of this experiment was to study the effects of drinking water feeding of Lactobacillus(Lactobacillus plantarum)preparations on production performance,egg quality,mineral content in eggs,and antioxidant capacity indexes of commercial laying hens in the late laying period.1125 healthy laying hens at 81 weeks of age were selected and chivided into 3 groups(5 replicates in each group,75 hens in each replicate),control group,test groupⅠandⅡ,fed the same diet conditions under drinking water fed with 0,3,5 mL/(each·d)dose of lactic acid bacteria preparation(live bacteria count≥1.0×10^(9) CFU/mL).The pre-feeding period was one week and the formal trial period was 44 d.The test results were as follows:①production performance:test groupsⅠandⅡsignificantly increased egg weight(P<0.05),and the egg production rate of test groupⅡsignificantly increased(P<0.05);there was a trend of improvement in the feed-to-egg ratio and egg breakage rate,but there was no significant difference compared with the control group(P>0.05);②egg quality:the test groupⅡcould significantly improve eggshell strength(P<0.05)and eggshell thickness(P<0.05)compared with the control group;the differences in eggshell thickness,hastelloy units and protein height were not significant(P>0.05);③mineral element content in eggs:test groupsⅠandⅡsignificantly increased magnesium(P<0.05)and zinc(P<0.05)content in eggs compared with the control group,and test groupⅡsignificantly increased calcium(P<0.05),but no significant differences in other mineral elements(P>0.05);④antioxidant capacity:test groupsⅠandⅡsignificantly increased the total antioxidant capacity compared with the control group(P<0.05),but no significant differences in other indicators(P>0.05).In conclusion,drinking water feeding of Lactobacillus plantarum preparation can improve production performance,egg quality and antioxidant capacity of 81-week-old laying hens with the recommended additive amount of 5 mL/(each·d).
