This study investigated the effect of dietary VA supplementation on maternal and its offspring in terms of the early growth performance, antioxidant index, and tissue VA content of the goslings. Yangzhou geese aged 180 D were selected and randomly distributed into 5 experimental groups with 15 female geese and 3 male geese in each group. The geese were fed a basal diet supplemented with 0, 4,000, 8,000, 12,000, or 16,000 IU/kg VA. Eggs were collected from each group starting at 300 D. After hatching, 96 goslings were selected from each maternal group and randomly distributed into 2 experimental groups with factorial arrangement (6 replicates × 8 geese), including 2 levels of VA supplementations, 0 and 9,000 IU/kg. The results are as follows: (1) Different levels of maternal VA supplementation significantly affected the BW and weight gain of 7-day-old offspring (P < 0.05). The weight gain of offspring administered 9,000 IU/kg VA was significantly higher than that of offspring administered the basal diet (P < 0.05). (2) Maternal VA levels significantly affected the T3, T4, and insulin levels of the offspring (P < 0.05). (3) The GSH-PX, SOD, T-AOC, CAT, and tissue VA content of the offspring were significantly higher and MDA was significantly lower in the 9,000 IU/kg VA group than in the no VA group (P < 0.05). (4) Maternal VA levels had a significant effect on offspring GSH, GSH-PX, SOD, MDA, T-AOC, and CAT (P < 0.05). Maternal and offspring VA supplementation interact with the weight gain, tissue VA content, GSH, GSH-PX, SOD, MDA, and CAT of goslings (P < 0.05). Maternal supplementation with 12,000 IU/kg VA and offspring supplementation with 9,000 IU/kg VA was conducive to gosling growth.

母体及其后代日粮补充维生素A对雏鹅早期生长性能、肝脏维生素A含量和抗氧化指数的影响。

本研究从幼鹅的早期生长性能、抗氧化指数和组织 VA 含量方面调查了日粮补充 VA 对母体及其后代的影响。选取180日龄扬州鹅,随机分为5个实验组,每组15只雌鹅和3只雄鹅。给鹅喂食补充有 0、4,000、8,000、12,000 或 16,000 IU/kg VA 的基础日粮。从 300 d 开始从每组收集鸡蛋。孵化后,从每个母组中选择 96 只小鹅,并以因子排列(6 个重复×8 只鹅)随机分配到 2 个实验组,包括 2 个水平的 VA 补充,0 和 9,000国际单位/公斤。结果如下:(1)母体不同VA补充水平显着影响7日龄子代的BW和增重(P < 0.05)。给予9,000 IU/kg VA的后代体重增加显着高于给予基础饮食的后代(P < 0.05)。(2)母体VA水平显着影响子代T3、T4和胰岛素水平(P < 0.05)。(3) 9000 IU/kg VA组子代GSH-PX、SOD、T-AOC、CAT及组织VA含量显着高于无VA组,MDA显着低于无VA组(P < 0.05) . (4)母体VA水平对子代GSH、GSH-PX、SOD、MDA、T-AOC、CAT有显着影响(P < 0.05)。母体和后代 VA 补充与幼鹅体重增加、组织 VA 含量、GSH、GSH-PX、SOD、MDA 和 CAT 相互作用(P < 0.05)。
