试验旨在探讨苦玄参提取物对仔猪血液生化指标、抗氧化功能和部分免疫指标的影响,为苦玄参提取物在仔猪生产中的合理利用提供理论依据。选取28~35日龄、体重相近的杜×长×大三元杂交断奶仔猪250头,随机分为5组(A、B、C、D、E组),每组5个重复,每个重复10头。其中A、B、C组依次为苦玄参提取物高、中、低剂量组,分别在基础日粮中添加3.5、1.75和0.875g/kg苦玄参提取物;D组为药物对照组,在基础日粮中添加4.0g/kg七补散;E组为空白对照组,饲喂基础日粮。预饲期7d,正试期30d。分别在用药14d后和停药14d后时,从每组中随机选取接近平均体重的10头仔猪于晨饲前进行前腔静脉采血,测定血清生化指标、抗氧化指标和免疫指标。结果显示:(1)各组仔猪血液生化指标差异均不显著(P0.05),说明苦玄参提取物对仔猪体内糖代谢、脂代谢及消化系统无显著影响;(2)从抗氧化指标看,添加苦玄参提取物14d后,B组一氧化氮(NO)含量极显著高于其他组(P0.01),A组总抗氧化能力(T-AOC)极显著高于其他组(P0.01),B、D组显著或极显著高于C、E组(P0.05;P0.01);而停药14d后,E组谷胱甘肽(GSH)含量显著高于B、C、D组,各组其余指标差异均不显著(P0.05);(3)从免疫指标看,添加苦玄参提取物14d后,B组免疫球蛋白G (IgG)含量极显著高于其他组(P0.01),A组白细胞介素6(IL-6)含量显著高于B、D、E组(P0.05);而停药14d后,各组免疫指标差异不显著(P0.05);综上所述,日粮中添加0.875~3.5g/kg苦玄参提取物对仔猪无不良影响,且可在一定程度上增强机体的抗氧化功能和机体免疫水平。 相似文献

试验旨在研究日粮中添加苦玄参提取物对广西麻鸡血清生化指标及免疫功能的影响。选用1日龄广西麻鸡500羽,随机分为5组（A、B、C、D、E组）,每组设5个重复,每个重复20羽。其中A、B、C组为试验组,分别在基础日粮中添加0.70%,0.35%和0.175%的苦玄参提取物;D组为阳性药物对照组,在基础日粮中添加0.01%硫酸黏菌素预混料;E组为空白对照组,饲喂基础日粮,预试期3 d,正试期49 d。于21、35和49日龄时分别从每组抽取10羽试验鸡进行心脏采血,测定血清生理生化及免疫指标。结果显示：与E组相比,日粮添加苦玄参提取物对鸡的血清TP、GLU含量无显著影响（P>0.05）;但21和35日龄时,A、B、C组的TBILI含量均极显著或显著低于E组（P<0.01;P<0.05）;35日龄时,A、B、C组的血清AKP活性均极显著高于E组（P<0.01）,C组的GOT活性在21和35日龄时显著高于E组（P<0.05）;49日龄时,A、B、C组的IgG和B、C组IL-2含量均显著或极显著低于E组（P<0.05;P<0.01）,B组T-AOC显著高于E组（P<0.05）,A、B、C组血清GSH含量均显著高于E组（P<0.05）。由此可知,日粮中添加的苦玄参提取物显著降低了广西麻鸡的血清TBILI含量,并在一定程度上降低了IgG、IL-2和IL-6含量,提高了AKP和GOT活性及T-AOC和GSH含量。综合考虑,以0.35%的添加量效果最好。 相似文献

试验旨在研究饲粮中添加复合植物提取物（主要成分为黄芪多糖和盐酸小檗碱）对断奶仔猪生长性能、腹泻率、血液生化和抗氧化指标的影响。选用75头初始体重为（7.59±0.39）kg的28日龄杜×长×大断奶阉公猪，随机分为3组，每组5个重复，每个重复5头仔猪。对照组饲喂不含抗生素的玉米-豆粕型基础饲粮，抗生素组在基础饲粮中添加160 mg/kg土霉素钙和40 mg/kg维吉尼亚霉素，复合植物提取物组在基础饲粮中添加500 mg/kg复合植物提取物，试验期42 d。结果表明：饲粮中添加复合植物提取物对断奶仔猪生长性能无显著影响，但具有提高仔猪体重的趋势；复合植物提取物组能够降低仔猪断奶后0～14 d的腹泻率、血清丙二醛和尿素氮含量（P<0.05），并具有提高血清免疫球蛋白G浓度的趋势（P=0.098）。可见，饲粮添加复合植物提取物（主要成分为黄芪多糖和盐酸小檗碱）虽未显著提高断奶仔猪的生长性能，但可能通过改善仔猪血清抗氧化、免疫和生化指标来降低仔猪断奶后腹泻率。 相似文献

[Objective] This trial was to investigate the effect of dietary Picria felterrae Lour extracts on serum biochemical indexes and immune function of Guangxi Partridge chickens. [Method] Totally 500 individuals of 1-day-old Guangxi Partridge chickens were randomly divided into five groups, five replicates each group and 20 chicks each replicate. Groups A, B and C were treatment groups supplemented with 0.70%, 0.35% and0.175% P. felterrae extracts in the basal diet, respectively; group D was a medical control group supplemented with 0.01% colistin sulfate premix in the basal diet; and group E was a control group with basal diet. Serum samples were collected from 10 chickens in each group at 21, 35 and 49 days of age, to analyze the biochemical and immune indexes. [Result] It had no significant impact on serum TP and GLU contents of chickens by adding different levels of P. felterrae extracts in the basal diet(P 0.05). However, at 21 and 35 days of age, the TBILI content of chickens in groups A, B and C were extremely lower or significantly lower than that in group E( P0.01; P0.05). At 35 days of age, the serum AKP activities in groups A, B and C were extremely higher than that in group E(P0.01), and the serum GOT activities at 21 and 35 days of age in group C were significantly higher than that in group E(P0.05). At 49 days of age, the serum Ig G content in groups A, B and C and the IL-2 content in group B and group C were significantly lower or extremely lower than that in group E( P0.05; P0.01); the T-AOC content in group B was significantly higher than that in group E(P0.05); the GSH content in groups A, B and C were significantly higher than that in group E( P0.05). Adding different levels of P. felterrae extracts in the diet significantly decreased the TBILI content, reduced the Ig G, IL-2 and IL-6 contents, and improved the AKP and GOT activities and the T-AOC and GSH contents of Guangxi Partridge chicken. [Conclusion] Adding 0.35% P. felterrae extracts in the basal diet received the best effort. 相似文献

This trial was conducted to investigate the effect of dietary Picriafel-tarrae Lour extracts on serum biochemical indexes and immune function of Guangxi Partridge chickens. 500 Guangxi Partridge chickens with 1 day old were randomly divided into 5 groups with 5 replicates per group and 20 chicks per replicate.Groups A,B and C were treatment groups and fed diets with 0.70%,0.35% and 0.175% Picriafel-tarrae Lour extracts,respectively,group D was a medical control group fed a diet with 0.01% colistin sulfate premix,and group E was control group fed basal diet. Serum samples were collected from 10 chicks in each group at 21,35 and 49 days old to analyze the biochemical and immune indexes. The results showed that compared with group E, the contents of GLU and TP were not significantly affected by the Picriafel-tarrae Lour extracts (P>0.05).However, in 21 and 35 days old, the TBILI content of groups A,B and C were extremely significantly or significantly reduced (P<0.01;P<0.05);At 35 days old,the activity of serum AKP of groups A,B and C were extremely significantly higher than that of group E (P<0.01),and the activity of serum GOT of group C at 21 and 35 days old were significantly higher than that of group E (P<0.05);At 49 days old,the serum IgG content of groups A,B,C and IL-2 of groups B and C were extremely significantly or significantly lower than those of group E (P<0.01;P<0.05);At 49 days old,the T-AOC of group B was significantly higher than group E (P<0.05);The GSH content of groups A,B and C at 49 days old were significantly increased than group E (P<0.05).In conclusion,the dietary Picriafel-tarrae Lour extract could significantly decreased the TBILI content,reduce the contents of IgG,IL-2 and IL-6, improve the activities of AKP and GOT,and the contents of T-AOC and GSH in some degree. The 0.35% additive amount had the better effects. 相似文献

The aim of this experiment was conducted to study the effects of fermented Atractylodes chinensis on serum immune and biochemical indexes of weaned piglets. Ninety-six Landrace ×Large White weaned piglets with weaning weight (6.0±0.5) kg were randomly allocated to 6 groups with 4 replicates per group and 4 weaned piglets per replicate. The weaned piglets were subjected to the following 6 treatments for 28 days:Control group was fed with the basal diet,groups Ⅰ and Ⅱ were fed with antibiotics and 0.2% unfermented Atractylodes chinensis in basal diet,while groups Ⅲ,Ⅳ and Ⅴ were supplemented 0.1%,0.2% and 0.3% fermentated Atractylodes chinensis in basal diet,respectively. The results showed that the immune and biochemical index of weaned piglets in fermented Atractylodes chinensis group had different degrees of improvement compared with control group and group Ⅰ.In the whole experimental stage,comparing with control group,the serum IgA,IgG,IgM,TP and ALB of weaned piglets in group Ⅳ were increased 10.5%,10.0%,7.8%,21.0% and 15.6%,respectively,and the difference were significant (P < 0.05),and serum ALT content was significantly reduced 20.4% (P < 0.05).Compared with group Ⅰ,the serum IgA,IgG,IgM and TP of weaned piglets in group Ⅳ were increased 7.1%,3.8%,3.8% and 12.6%, respectively,the difference were significant (P < 0.05),while the serum ALB, AST and BUN of group Ⅳ were increased 1.0%, 9.5% and 15.0%, and the difference were not significant (P > 0.05), and serum ALT content was reduced 9.4% compared with the antibiotics group (P > 0.05). 相似文献

This experiment was conducted to study the effects of ampelopsis grossedentata flavonoids on serum biochemical indexes and immune function of piglets.24 healthy piglets were selected and divided into 4 groups for 40 days feeding experiment.Control group was fed with basal diet and treatment groups were fed with 0.25%, 0.5% and 1% AGF adding to basal diet, respectively.At the end of feeding experiment, two piglets from each group were selected and blood samples were collected to analyze the physiological and biochemical indexes of serum.The results showed that AGF could significantly improve the content of ALB in serum (P<0.01), and decrease the serum BUN content in piglets, 0.5% and 1% groups had extremely significant difference with control group (P<0.01);TG content in treatment groups were decreased and 0.25% and 0.5% groups had significant difference with control group (P<0.05).AST content in serum of treatment groups significantly reduced comparing with the control group (P<0.05);ALP content of treatment groups were increased and 0.5% group was extremely significantly different from control group (P<0.01);AGF could extremely significantly improve serum IgM content (P<0.01), extremely significantly increase the IgG content of 0.5% and 1% groups (P<0.01), and improve serum complement C3 and C4 contents of 0.25% and 0.5% groups.In conclusion, AGF could enhance the piglet metabolism ability and immune function. 相似文献
