Non-antibiotic anti-microbial effect of Nutritional additives.

This thesis presents the study focus on the response of piglet GI tract microbiota afer the supplementation with different feed additives, combine with different research methods. This research work is focus on the relationship between feed additives and intestinal health. The gastrointestinal (GI) tract of pigs is colonized by a variety of active microbiota which shows the symbiotic relationship with host. Also the gastrointestinal tract microbiota plays such an important role in pig health. Supplementing pigs with different diet ingredients that can have an effect on the GI tract microbiota is a common strategy to affect pig’s health. In this study, in order to detect the non-antibiotic anti-microbial effect of nutritional additives, all the three trials show three different resource additives using variety tecniques. This study consists of three independent trials; all the feed additives used in this study are non-antibiotic aim to increase the intestinal anti-microbial effect. The application of different techniques in this thesis show the anti-microbial effect of different non-antibiotic feed additives which provided important information of following research works.
