Project description:Sialyllactose supplementation in pig milk replacer could promote cognitive functions in postnatal piglet behaviour experiment. There are 2 groups of 3-day-old postnatal piglets, feeding basal level and sialyllactose. After 35 days feeding, sialyllactose group showed better performance in behaviour experiment. We used microarrays to detail the global programme of gene expression underlying the nervous system development and memory formation.
Project description:This agent-based model is based on an adaptive laboratory evolution (ALE) experiment scenario of two mutually cross feeding strains of bacteria and yeast. The bacterial strain secretes vitamins for which the yeast strain is auxotrophic and the yeast strain secrets amino acids for which the bacterial strain is auxotrophic. In particular, the model simulates a situation where a mutation arises in the bacterial strain that results in the emergence of individuals (mutant bacteria) with a higher secretion of vitamins as compared to the wild type (WT). This increase in secretion comes with a cost in terms of fitness (growth rate) of the mutant bacteria. The model can be used to assess if this mutant is able to persist and increase in frequency in the cross-feeding community.
Project description:Lactoferrin supplementation in pig milk replacer could promote cognitive functions in postnatal piglet behaviour experiment. There are 3 groups of 3-day-old postnatal piglets, feeding basal level, medium dose(0.6g/L) and high dose(1.2g/L) lactoferrin. After 35days feeding, medium dose group showed better performance in behaviour experiment. We used microarrays to detail the global programme of gene expression underlying the nervous system development and memory formation.
Project description:The main objective was to identify genes regulated during different stages of fermentation: bottom of the fermentor, feeding and the fermentation stage. The experiment was further validated by microbiological assays.
