Effects Of Commercial Feed Additives On Growth Performance And Gut Microbiota Of Nursery Pigs, Xiaoyuan Wei
Effects Of Commercial Feed Additives On Growth Performance And Gut Microbiota Of Nursery Pigs, Xiaoyuan Wei
Graduate Theses and Dissertations
To secure animal welfare and maximum production, feed additives are often added to nursery pig diets to increase nutrition digestibility, enhance intestinal health, and prevent or mitigate disease, with the ultimate goal of improving growth performance. This thesis performed a longitudinal analysis using next-generation sequencing to investigate the dynamic changes of gut microbiota in weaned pigs fed commercial feed additives. Chapter II was used to evaluate the effects of organic acid mixture on growth performance and gut microbiota of weaning pigs. This study demonstrated that the inclusion of 0.035% (SBA0.035) or 0.070% (SBA0.070) sodium butyrate in a diet containing 0.5% …
Characterization Of The Swine Gut Microbiome Dynamics, Culturomics And Probiotics, Xiaofan Wang
Characterization Of The Swine Gut Microbiome Dynamics, Culturomics And Probiotics, Xiaofan Wang
Graduate Theses and Dissertations
The gastrointestinal tract is a critical place where the immune system concentrates many of its protective functions. It exerts both physical and biochemical defenses against invading foodborne pathogens and other hazards. In pigs, the gut microbiota community assembled postnatal plays a very important role in the development of multiple physiologic aspects, such as development of the gastrointestinal tract, nutrient exchange, immune defense against foreign pathogens and growth performance. Microbiome-host communication changes with age. Despite recent advances in understanding the swine gut microbiome at different growth stages, a comprehensive longitudinal study of the lifelong dynamics of the swine gut microbiome is …
