The aim of the study was to determine the influence of the effective microorganisms (EM) on performance parameters, intestinal morphology and gene expression in the jejunal mucosa in pigs under different feeding regimes. The study group comprised of 150 piglets divided into three feeding groups: C, E1 and E2. Feeding groups included: C—standard fodder, blend with a full share of post‐extracted soy meal, E1—in the phase I of fattening: pea and lupin/soybean 50/50%; in the phase II of fattening: pea and lupin/soybean 75/25%, and E2—in the phase I of fattening: pea and lupin/soybean 50/50%; in the phase II of fattening: pea and lupin 100%. The experimental factor was addition of a probiotic EM Carbon Bokashi to the diets (C + EM, E1 + EM and E2 + EM). After slaughter, histological evaluation and gene expression analysis were performed. The highest intestinal villi were reported in E2 + EM. A higher intestinal absorption area was demonstrated in groups C + EM and E2 + EM. An interaction between feeding and EM Bokashi supplementation was found in villus surface area crypt depth, villus height/crypt depth and number of goblet cells. Mucosa thickness and number of goblet cells was the largest in E2 + EM. Gene expression of FABP4 increased in E1, and GLUT2 decreased in E2. Gene expression of IL10 and FABP4 increased in E2 + EM. The results indicate that the E2 diet is more optimal for EM Bokashi supplementation, because in this group, EM positively influenced the morphological characteristics of the porcine jejunum and caused an increase in the expression of genes related to the metabolism and functioning of the gastrointestinal tract.

有效微生物(EM)对饲喂不同日粮的猪空肠黏膜的性能,肠道形态和基因表达的影响。

该研究的目的是确定有效微生物(EM)对不同喂养方式下猪空肠黏膜性能参数,肠道形态和基因表达的影响。该研究组由150只仔猪组成,分为三个饲养组:C,E1和E2。饲喂组包括:C –标准饲料,与全部提取后的大豆粉混合,E1 –在育肥的第一阶段:豌豆和羽扇豆/大豆50/50%;在育肥的第二阶段:豌豆和羽扇豆/大豆75/25%,以及E2-在育肥的第一阶段:豌豆和羽扇豆/大豆50/50%;在育肥的第二阶段:豌豆和羽扇豆100%。实验因素是在饮食中添加了益生菌EM Carbon Bokashi(C + EM,E1 + EM和E2 + EM)。宰杀后,进行组织学评估和基因表达分析。E2 + EM中肠绒毛最高。C + EM组和E2 + EM组有较高的肠道吸收面积。在绒毛表面积隐窝深度,绒毛高度/隐窝深度和杯状细胞数量中发现了进食和EM Bokashi补充之间的相互作用。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。C + EM组和E2 + EM组有较高的肠道吸收面积。在绒毛表面积隐窝深度,绒毛高度/隐窝深度和杯状细胞数量中发现了进食和EM Bokashi补充之间的相互作用。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。C + EM组和E2 + EM组有较高的肠道吸收面积。在绒毛表面积隐窝深度,绒毛高度/隐窝深度和杯状细胞数量中发现了进食和EM Bokashi补充之间的相互作用。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。在绒毛表面积隐窝深度,绒毛高度/隐窝深度和杯状细胞数量中发现了进食和EM Bokashi补充之间的相互作用。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。在绒毛表面积隐窝深度,绒毛高度/隐窝深度和杯状细胞数量中发现了进食和EM Bokashi补充之间的相互作用。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。黏膜厚度和杯状细胞数量在E2 + EM中最大。E1中FABP4的基因表达增加,而E2中GLUT2的基因表达减少。在E2 + EM中,IL10和FABP4的基因表达增加。结果表明,E2饮食更适合EM Bokashi补充,因为在该组中,EM积极影响猪空肠的形态特征,并导致与胃肠道代谢和功能相关的基因表达增加。
