母源补喂竹叶提取物对伊犁马幼驹血液生化指标的影响

【目的】研究伊犁马补喂竹叶提取物对其幼驹血液生化指标的影响。【方法】试验选取24匹体重、年龄、胎次相近的泌乳期伊犁马及其哺乳幼驹,在母马饲粮中添加30 g/d的竹叶提取物,母马摄食后,幼驹自由采食母乳,在试验的第0、15、30、45、60 d分别对幼驹采血,检测其血液免疫指标、抗氧化指标、激素指标、血清蛋白含量。【结果】(1)IgG、IgM的含量均在饲喂第15 d极显著高于0 d(P<0.01),显著高于45 d(P<0.05),60 d显著高于0 d(P<0.05)。TNF-α含量在第30、45、60 d极显著高于0 d(P<0.01),15 d显著高于0 d(P<0.05)。IL-1β含量在第30、45 d极显著高于0 d(P<0.01),60 d显著高于0 d(P<0.05)。(2)SOD含量在第45、60 d极显著高于45 d(P<0.01),0 d显著高于45 d(P<0.05)。MDA含量在第45 d极显著低于第15 d(P<0.01),显著低于60 d(P<0.05)。-OH含量在第45 d极显著低于第15、60 d(P<0.01),显著低于第0、30 d(P<0.05)。(3)T₄水平在第60 d极显著高于15 d(P<0.01),30、45 d显著高于15 d(P<0.05)。GH水平在第30、45 d显著高于0 d(P<0.05)。IGF-1水平在第30、45 d显著高于0 d(P<0.05)。(4)TP、ALB含量在第45 d极显著高于30 d(P<0.01)。GLB含量在第45 d显著高于0、30 d(P<0.05)。A/G第0 d极显著高于30 d(P<0.01),显著高于45 d(P<0.05)。【结论】在伊犁马母马饲粮中添加竹叶提取物,能显著提高马驹的免疫性能、抗氧化性能、激素水平、血清蛋白含量。

Effects of Different Time of Yili Mare Supplementing Bamboo Leaf Extract on the Blood Biochemical Indexes of Young Foals

【Objective】 To study the effect of Yilimare supplementation with bamboo leaf extract on the blood biochemical indexes of young foals in this experiment. 【Methods】 24 lactating Yilimares with similar body weight, age and parity and their suckling foals were selected, and 30 g/d bamboo leaf extract was added to the mare's diet. After the mares ingested, the foals freely consumed breast milk. On the 0 th, 15 th, 30 th, 45 th, and 60 th days of the experiment, blood was collected from the young foals, and their blood immune indexes, antioxidant indexes, hormone indexes, and serum protein contents were tested. 【Results】 (1) The contents of IgG and IgM on the 15 day of feeding were significantly higher than those on 0d (P<0.01), significantly higher those than 45 d (P<0.05), and 60 d later it was significantly higher than those 0d (P<0.05). The content of TNF-αon on the 30, 45, and 60 d, was significantly higher than those 0d (P<0.01) and was significantly higher than 0 d on the 15 day (P<0.05). The IL-1β content was significantly higher than those on 0d (P<0.01) on the 30 and 45 day, and significantly higher than 0d on the 60 day (P<0.05). (2) The SOD content was significantly higher than those 45 d (P<0.01) on the 45 and 60 d, and significantly higher than 45 d (P<0.05) at 0 d. The MDA content on the 45 day was significantly lower than that on the 15 day (P<0.01), and significantly lower than on the 60 day (P<0.05). -OH content on the 45th day was extremely significantly lower than on the 15 and 60 day (P<0.01), and significantly lower than on the 0^th and 30 day (P<0.05). (3) T₄ level was significantly higher than 15 d on the 60 day (P<0.01), and significantly higher than 15 d on the 30th and 45 day (P<0.05). The GH level was significantly higher than 0d on the 30 and 45 day (P<0.05). The level of IGF-1 was significantly higher than that on day 30 and 45 (P<0.05). (4) The content of TP and ALB on the 45th day was extremely significantly higher than that on the 30th day (P<0.01). The GLB content was significantly higher than 0 and 30 d on the 45th day (P<0.05). The 0 d A/G was extremely significantly higher than 30 d (P<0.01), and significantly higher than 45 d (P<0.05). 【Conclusion】 In conclusion, under the experimental conditions, adding bamboo leaf extract to the diet of Yili horse mares can significantly improve the immune performance, antioxidant performance, hormone level, and serum protein content of the foal.
