摘要

The effect of feeding encapsulated and non-encapsulated Pediococcus acidilactici on body weight gain, feed conversion efficiency, meat quality and ultra structural changes of intestinal (ileum) villus in commercial male broiler chicks was evaluated. Group 1 (Control) was fed with feed without supplementation of any probiotic organism, Group 2 was fed with non-encapsulated P. acidilactici (NEPA) @ 106 cfu/ g supplemented diets. Groups 3 and 4 were fed with low and high level of encapsulated Pediococcus acidilactici diets (EPAL and EPAH) @ 106cfu/g and 109 cfu/g, respectively. The body weight gain during the (0-3) and (0-6) week in the control group was significantly (P<0.05) lower than NEPA, EPAL and EPAH groups. EPAL and EPAH groups showed significantly (P<0.05) better feed conversion ratio (FCR) compared to control group at the end of 3rd and 6th week. The sensory evaluation scores of meat revealed a significant (P<0.05) improvement in juiciness, tenderness and overall acceptance in probiotic fedbroilers compared to control group. The Scanning Electron Microscopy of ileum revealed increased villus width and length (area) in EPAH group compared to all other groups (Control, NEPA and EPAL). However, NEPA and EPAL fed chicks have higher villus areacompared to control group. An excellent adhesion of Pediococcus acidilactici on intestinal walls was seen in EPAL and EPAH birds compared to control and NEPA group. Encapsulated Pediococcus acidilactici enhanced the colonization and adhesion of probiotics on the surface of intestines besides increasing the density, length and width of intestinal villus resulting in better performance and meat quality in broilers.
