Cellobiohydrolase and β-glucosidase mostly located at the hindgut, at which they accounted for 83.3% and 80.2% of the total cellulases in gut tissue respectively. C1和β葡糖苷酶绝大部分在后肠,在该部位所含酶量分别占整个肠道组织酶总量的833%和802%。
Study on Digestion of Dietary Nutrients in Hindgut of Sheep 绵羊后肠道对日粮养分消化的研究
The dietary protein levels have an influence on nutrient digestion in the hindgut of sheep. 不同的粗蛋白水平对绵羊日粮养分后肠道的消化有一定的影响。
As for the whole gut tissues, cellulases mainly distributed in the foregut and hindgut. 肠道组织中,3种纤维素酶主要分布于前肠和后肠组织。
Study on Inulin's Function of Hindgut Microbe in Weaning Piglets and Broilers 菊粉对断奶仔猪和肉仔鸡后肠微生物作用的研究
Results: the distribution density of Glu cells is higher in the midgut, lower in the foregut and hindgut of S.prenanti; 结果:Glu细胞在齐口裂腹鱼肠道中以中肠分布最密集,前肠和后肠分布密度较低;
The epithelium cells of digestive tube with or without the striated border can be used as one of important standard for distinguishing the midgut from foregut and hindgut. 消化道上皮细胞有无纹状缘是区分中肠与前、后肠的重要标准之一。
Omnivores have more complex gastrointestinal tracts, with a hindgut caecum in which some microbial fermentation takes place, and they have longer mean retention times ( MRTs) of digesta. 杂食性动物有更复杂的胃肠器官,其后端有可进行发酵的盲肠,消化物的平均滞留时间(meanretentiontimes,MRTs)更长;
Enumeration by plate-counting and rolling tube methods indicated that there were abundant symbiotic bacteria resided in hindgut of termite Coptotermes formosanus. 好氧平板和厌氧滚管菌落计数表明,台湾家白蚁的工蚁和兵蚁肠道中有大量的异养型共生细菌。
Digestion of starch in the hindgut was less than 1% for all diets. 淀粉在后肠道消化不到1%。
The hindgut is short, has no striated border. 后肠很短,无纹状缘。
Effect of Dietary Crude Protein Levels on Nutrients Digestion in the Hindgut of Sheep 粗蛋白水平对绵羊日粮养分后肠道消化的影响
The fermentation pattern in the hindgut of finishing pigs was acetate fermentation type. 后肠微生物发酵类型为乙酸发酵型。
There are mass symbiotic bacteria and protozoans in the hindgut of lower termite, which could produce multiple cellulase for hydrolysing plant cellulose. 低等白蚁后肠富含细菌、原生动物等共生微生物,它们分泌产生的纤维素酶,与白蚁内源性纤维素酶一道共同完成食物中纤维素类物质的降解。
Digestion of NDF in the hindgut as a percentage of total tract digestion averaged 28.2%, 24.7%, 23.4% and 22.8% for the respective diets. NDF相应为28.2%、24.7%、23.4%和22.8%;
The fish were sampled 3, 6, 12, 24, 48 and 72 hours after being fed with food and the bacterial composition and number in the fore, mid and the hindgut were examined. 将摄食后的草鱼分别于3、6、12、24、48和72h取样,对其前、中、后肠内的细菌数量和组成进行了分析。
Results indicated that the hindgut of sheep played an important role in the digestion of dietary nutrients. 绵羊后肠道在日粮养分消化中的具有较为重要的作用。
The posterior midgut is smaller than the anterior midgut in diameter comparing with the anterior midgut. Numerous different concentric circular are characteristic of the posterior midgut. The hindgut arises from the posterior midgut at the boundary of the filter chamber. 与前中肠相比,后中肠直径较小,存在大量的同心环状体。
Lysozyme content in serum, mucus, liver, stomach and hindgut showed significant difference between the lowest and the highest temperature in the test while that in the other tissues showed no significant difference. 血清、粘液、肝、胃及后肠在本研究的最低温和最高温时有显著性的差异,其余各组织的溶菌酶随温度变化无显著性差异。
Lymphocytes presented in skin, gill, hindgut, head kidney, spleen and peripheral blood ( PBL) after micro observation to tissue sections. 组织切片显微观察发现,大菱鲆皮肤、鳃、后肠、头肾和脾中存在淋巴细胞。
