3.2.2. Bacterial population in intestine
Pigs fed SF diet had greater (Pb0.05) Lactobacillus spp. and
less Clostridium spp. (Pb0.01) and coliform (Pb0.05) population
in the ileum than pigs fed LF diet (Table 8). Additionally,
higher (Pb0.05) caecal Bifidobacterium spp. population
was observed in pigs fed SF diet. Antibiotics had no effect on
the ileal microbial population; however, pigs fed colistin diet
had less number of Bifidobacterium spp. (Pb0.05) and coliforms
(Pb0.01) in the cecum, whereas, feeding of lincomycin
diet resulted in reduced (Pb0.05) caecal Clostridium spp.
population.
3.2.3. Small intestinal morphology
The different probiotic products and antibiotics had no
influence on the morphology of different segments of the
small intestine, except for the greater (Pb0.05) villus height:crypt depth at the jejunum and ileum noticed in pigs fed
lincomycin diet (Table 9).
4. Discussion
Previous studies on probiotics lack information on the
method of production used, however, the preparation of
probiotics by LF method is fairly common (Patel et al., 2004).
The probiotic products used in the present study differed
from the previous reports in that harvested probiotic
microbes were added directly to the diets. In this study, the
microbial biomass grown on the CB was directly sprayed on
the carrier (corn and soybean meal) to obtain LF probiotic
product. In case of the SF probiotic product, corn and soybean
meal was used as a substrate during fermentation and as a
carrier of probiotic microbes. We have reported previously
that multi-microbe probiotic product prepared by SF method
was better than the probiotic product prepared by submerged
liquid fermentation in improving performance, nutrient
retention and reducing harmful intestinal bacteria in broilers
(Shim et al., 2010). In the current study, LF and SF method
was used and corn–soybean meal was used as a substrate forthe growth of potential probiotic microbes under optimum
conditions.

第3.2.2章. 在肠道内细菌种群
与喂养LF饲料的猪相比(表8),在喂养SF饲料的猪的回肠道中乳酸菌属的数量较多(Pb0.05),梭菌属(Pb0.01)与大肠杆菌属(Pb0.05)的数量较少.
此外,在喂养SF饲料的猪的盲肠中发现较多的双歧杆菌属菌种(Pb0.05).
抗生素对回肠中的微生物种群没有影响,然而,喂养含粘菌素饲料,会导致猪的盲肠中双歧杆菌属(Pb0.05)和大肠杆菌属(Pb0.01)的数量下降.
相反的,喂养含洁霉素饲料,会导致猪的盲肠中梭菌属(Pb0.05)的数量减少.
3.2.3. 小肠形态学
除了喂养含洁霉素饲料会导致猪空肠和回肠的绒毛高度 （窝深度 ）增加(Pb0.05)外,不同的益生菌产品和抗生素不会对小肠的不同部位的形态产生影响.
4.讨论
虽然先前对益生菌的研究缺乏关于产品使用方法的信息
,但采用LF方法制备益生菌还是相当普遍的(Patel et al., 2004).
在本研究中,益生菌产品的使用不同于先前的报道,而是直接将提取的益生菌添加到饲料中.
在本研究中,在CB上生长的微生物被直接喷洒在介质上(玉米和大豆),进而获得LF益生菌产品.
益生菌产品（玉米和大豆）被用作发酵过程中的基质和益生菌的载体.我们以前有报告采用LF方法制备益生菌在改善性能,营养保留和减少有害肠道细菌方面要比用液态发酵的方法来得好(Shim et al., 2010).
在目前的研究中,采用LF和SF方法,以玉米和黄豆粉为基质,在最佳条件下培养益生菌.
