摘　　要：本试验旨在研究种母鸭核黄素缺乏对子代初生雏鸭初生重、器官指数、体尺指标和血浆生化指标的影响。选取40周龄、体重和产蛋率相近的种母鸭80只,随机分为2组,分别饲喂不添加核黄素的饲粮(核黄素缺乏组)和核黄素添加量为15 mg/kg的饲粮(对照组),每组10个重复,每个重复4只鸭。试验期为7周。收集试验第7周的种蛋并进行孵化,统计产蛋率、受精率和孵化率,测定种蛋蛋黄核黄素含量,并测定子代初生雏鸭的器官指数、体尺指标、血浆生化指标及核黄素含量。结果表明:1)与对照组相比,种母鸭饲粮中不添加核黄素对产蛋率和受精率无显著影响(P>0.05),但可以显著降低种蛋孵化率(P<0.05);2)与对照组相比,核黄素缺乏可显著增加子代初生雏鸭卵黄囊重、卵黄囊指数(P<0.05),显著降低子代初生雏鸭腿长(P<0.05),显著降低种蛋蛋黄和子代初生雏鸭血浆核黄素和总胆固醇含量(P<0.05),显著升高血浆碱性磷酸酶活性和尿酸含量(P<0.05)。综上所述,种母鸭饲粮核黄素缺乏会严重降低种蛋孵化率、种蛋蛋黄和初生雏鸭血浆核黄素含量,导致鸭胚生长发育受阻,子代初生雏鸭蛋白质、核酸和脂质代谢异常。This experiment was conducted to investigate the effects of riboflavin deficiency of duck breeders on birth weight,organ indexes,body shape indexes and plasma biochemical indexes of offspring.A total of 80 white Pekin duck breeders aged 40 weeks with similar body weight and egg production were allotted to two groups,which fed the basal diets without riboflavin(riboflavin deficiency group)and with 15 mg/kg ribofla vin(control group),respectively,with ten replicates per group and four breeders per replicate.All birds were raised individually for 7 weeks.At the 7th weeks of the experiment,the eggs were collected for incubation,and the egg production,fertility,hatchability and egg yolk riboflavin content were determined.And organ in dexes,body shape indexes,plasma riboflavin content and plasma biochemical indexes of the offspring were measured.The results showed as followed:1)compared with the control group,riboflavin deficiency did not affect the egg production and fertility rate(P>0.05).However,riboflavin deficiency reduced the hatchability significantly(P<0.05).2)Compared with the control group,the offspring of riboflavin deficiency group had a greater egg sac weight,egg sac index,plasma alkaline phosphatase activity and plasma uric acid content(P<0.05),while had a lower leg length,egg yolk riboflavin,plasma riboflavin and total cholesterol contents(P<0.05).In conclusion,riboflavin deficiency in the diet seriously reduces the hatchability,egg yolk riboflavin,plasma riboflavin content of offspring,results in abnormal protein,lipid and nucleic metabolism,which lead ing to growth inhibition of offspring.[Chinese Journal of Animal Nutrition,2020,32(5):2185 2191]
