The interaction effect of whole wheat feeding and mannanoligosaccharides supplementation on growth performance, haematological indices and caecal microbiota of cockerel chicks were investigated using 250‐day‐old cockerel chicks previously reared for 7 days pre‐experimental period. Birds were fed with commercial chick mash during the pre‐experimental period. At the expiration of this period, 192 chicks were selected on weight equalization basis and assigned into 24 pens. Each treatment consisted of six pens, while each pen housed eight birds. Four wheat–soya bean‐based experimental diets were formulated in a 2 × 2 factorial arrangement of diets having two wheat forms (ground and whole wheat grain) each supplemented or not with 1 g/kg MOS/kg feed. Whole wheat feeding (irrespective of MOS supplementation) showed reduced (p < 0.05) feed intake. Birds fed whole wheat diet supplemented with MOS recorded the highest (p < 0.01) final live weight, weight gain and the best (p < 0.05) feed conversion ratio. Haemoglobin concentration, packed cell volume and red blood cell count of the chicks were not affected (p > 0.05) by dietary treatment. However, dietary supplementation with MOS resulted in increased (p < 0.05) WBC counts. The caecum content of chicks fed with MOS‐supplemented whole wheat diets recorded the least (p < 0.01) salmonella counts. In conclusion, combination of whole wheat feeding and MOS supplementation showed improved growth performance, gut microbiota and indications of improved health status of cockerel chicks. 相似文献

中草药对蛋雏鸡生长性能和免疫功能的影响 总被引：19，自引：0，他引：19
研究了中草药女贞子、五味子、四君子汤和六味地黄丸，以及甘露寡糖和黄霉素对蛋雏鸡生长性能、甲状腺素分泌和免疫机能的影响。试验选用294只1日龄海兰褐健康蛋公雏，随机分为7组，每组设3个重复，每重复14只。对照组饲喂基础日粮，试验组日粮分剐为：基础日粮 1％中草药、基础日粮 50mg／kg甘露寡糖、基础日粮 5mg，／kg黄霉素。结果表明，上述饲料添加剂对蛋雏鸡的生长性能和血浆T3和T4的含量以及T3／T4均无不同影响；与对照组相比，试验所用4种中草药均可显著提高血清抗新城疫抗体水平，而甘露寡糖与黄霉素作用不明显；与对照组相比，各试验组雏鸡脾淋巴细胞转化率均有所提高，其中女贞子组的转化率显著提高，表明本试验所用几种添加剂均有增强细胞免疫的作用。 相似文献

选择120只1日龄肉鸡随机分为2组,试验组添加0.3%的甘露寡糖。每组6个重复,每个重复10只。每组基础日粮相同。试验结果表明:试验后期(4~5周龄)和整个试验期(0~5周龄)的增重,添加0.3%甘露寡糖组显著高于对照组(P<0.05),试验前期(0~3周龄)未见明显效果。试验前期的料肉比,添加0.3%甘露寡糖组显著低于对照组(P<0.05),试验后期和整个试验期处理组虽然均低于对照组,但无显著差异。添加0.3%甘露寡糖组回肠绒毛长度以及绒毛长度与隐窝深度之间的比值均显著高于对照组(P<0.05)。添加0.3%甘露寡糖可显著提高肉鸡的生长性能,并可以改善肠黏膜的形态,增大小肠吸收面积。 相似文献

不同水平甘露寡糖对肉鹑生长性能和血清胆固醇的影响 总被引：1，自引：0，他引：1
为了探讨不同水平甘露寡糖对肉鹑生产性能和血清胆固醇的影响。将240只1日龄鹌鹑随机分成4组,每组设4个重复,每个重复15只鹌鹑,Ⅰ组为对照组,饲喂基础日粮,Ⅱ~Ⅳ组为试验组,在基础日粮中分别添加0.5%、1%、2%的甘露寡糖,进行为期50 d的饲养试验。结果表明,与对照组相比,Ⅲ、Ⅳ组的35日龄和50日龄的肉鹑的体重分别提高2.02%、2.66%,7.36%、7.90%。血清胆固醇含量:Ⅱ组35日龄肉鹑胆固醇含量比对照组升高22.22%,Ⅱ组50日龄肉鹑胆固醇含量比对照组降低12.20%;Ⅲ组35日龄肉鹑和50日龄肉鹑的胆固醇含量分别降低3.70%、9.76%,Ⅳ组35日龄肉鹑胆固醇含量比对照组升高7.41%,50日龄肉鹑的胆固醇含量降低21.95%。试验研究表明:在肉鹑生产中,适量添加甘露寡糖可增加肉鹑体重并且降低胆固醇含量。 相似文献

A feeding trial was conducted to evaluate the effects of mannanoligosaccharides (MOS) on nutrient digestibility, intestinal pH, gut morphology and faecal bacteriology of pigeons, as model for birds without functional caeca. Sixteen adult pigeons (Columba livia domestica) were randomly allotted to either an extruded pellet diet with or without 0.4% MOS. After an adaptation period of 24 days, excreta were collected during 4 days. Apparent nutrient digestibility coefficients were determined using total collection method. Further, excreta pH was measured and percentage of uric acid determined. Fresh excreta were cultured for measurement of colony‐forming units for Escherichia coli. At the end, the gastrointestinal tract (GIT) was excised and pH measurements performed on the separate GIT sections. Finally, pancreas, liver, gizzard and abdominal fat pad were weighed, and standardised segments of duodenum and jejunum were removed for microscopic measurement of crypt depth, villus height and muscularis thickness. Feed intake and water intake were similar between control diet and MOS diet. Intestinal pH was unaffected by MOS supplementation; however, excreta pH was significantly lower in pigeons on the MOS diet. Although nutrient digestibility was similar between treatments, uric acid content of excreta was significantly higher in the MOS group in relation to the control group. Further, duodenal crypt depth, villus height and muscularis thickness, as well as jejunal muscularis thickness were all significantly reduced by MOS supplementation. No effect of MOS supplementation was seen on the counts of E. coli. Furthermore, despite marked differences on both GIT morphology and uric acid content of excreta, apparent digestibility coefficients, and organ weights, were similar between treatments. It is suggested that the MOS‐induced changes on gut morphology and the reduced excreta pH reflect a reduced bacterial challenge in the intestine of pigeons. Supplementation of MOS, therefore, has potential as prebiotic strategy in birds without functional caeca. 相似文献
