摘要: 【目的】本研究旨在探讨生物素在蛋鸭生产中的应用效果及对蛋鸭卵巢发育和胫骨性状的影响。【方法】采用单因素完全随机试验设计,将432羽健康、处于产蛋高峰期的福建龙岩山麻鸭随机分为6个处理,每个处理6个重复,每个重复12羽。采用小麦-豆粕型基础饲粮,生物素添加水平分别为0、0.05、0.10、0.15、0.20、0.25 mg/kg,试验期12周。于第12周,每个重复随机选取4枚蛋,以及2只试验鸭进行采血、屠宰取样,检测蛋品质、血液生化指标及卵巢发育和胫骨性状指标。【结果】①饲粮生物素添加水平对产蛋性能影响不显著(P>0.05)。②饲粮生物素添加水平为0.10 mg/kg时,蛋黄重量最低,显著低于0.05和0.20 mg/kg添加组(P<0.05);随饲粮生物素添加水平升高,蛋黄中胆固醇(CHO)含量呈现升高趋势(P<0.05)。与对照组相比,生物素添加水平为0.25 mg/kg时,蛋黄中丙二醛(MDA)含量显著下降(P<0.05)。③饲粮生物素添加水平对蛋鸭血浆生化指标、卵巢发育指标及胫骨发育指标均无显著影响(P>0.05)。【结论】饲粮中添加不同水平生物素对高峰期蛋鸭产蛋性能、卵巢发育和胫骨性状均无显著影响;饲粮添加生物素水平为0.25 mg/kg时可降低蛋黄脂质过氧化水平,添加水平为0.10~0.25 mg/kg时增加了胆固醇在蛋黄中的沉积。

Abstract: 【Objective】 This study was designed to explore the application effects of biotin in diet of laying ducks and its effects on ovarian development and tibia characteristics.【Method】 A single factor completely randomized experimental design was adopted.A total of 432 healthy Fujian Longyan ducks in peak laying period were randomly divided into 6 groups with 6 replicates in each group and 12 ducks in each replicate.A wheat-soybean meal based diet was adopted,and the dietary biotin supplemental levels were 0,0.05,0.10,0.15,0.20 and 0.25 mg/kg,respectively.The experiment lasted for 12 weeks. At the 12th week, 4 eggs and 2 test ducks were randomly selected from each repetition for blood sampling and slaughter sampling to detect egg quality, blood biochemical indicators, ovarian development and tibia traits.【Result】 ①Dietary biotin supplemental level had no effect on laying performance (P>0.05).②When dietary supplemental biotin level was 0.10 mg/kg,the yolk weight was significantly lower than that of 0.05 and 0.20 mg/kg groups (P<0.05). With the increase of dietary supplemental biotin level, the yolk cholesterol (CHO) content was on the rise (P<0.05).Compared with the control group,the malondialdehyde(MDA) content in yolk was significantly decreased at 0.25 mg/kg biotin supplemental level (P<0.05).③Dietary biotin supplemental level had no significant effects on plasma biochemical indexes,ovarian development and tibia characteristics of laying ducks (P>0.05).【Conclusion】 Dietary biotin supplement had no effect on production performance,ovary development and tibia characteristics of laying ducks in peak period.When biotin supplemental level was 0.25 mg/kg,the degree of lipid oxidation in yolk was reduced,while cholesterol deposition in egg yolk was increased when it was 0.10 to 0.25 mg/kg.
