Effect of sodium humate and zinc oxide on health status and faecal bacterial communities in weaned piglets

Popis výsledku v původním jazyce

The aim of this study was to investigate the effect of sodium humate (HNa) and zinc oxide (ZnO) used in prophylaxis of post-weaning diarrhoea on the composition of faecal microbiota of piglets using high throughput sequencing. Weaned piglets were divided into three groups: control group without any treatment (C), group treated with 2 500 mg ZnO (A), and group treated with 20 g HNa and 1 700 mg ZnO (B) per kg of diet. Piglets of all groups were challenged with enterotoxigenic Escherichia coli strains (ETEC) on day 4 post-weaning. An intense diarrhoea with high mortality developed in C, while the A and B treatments both protected piglets from clinical signs of diarrhoea, mortality and depression of growth performance. A higher relative abundance of Gammaproteobacteria (mainly genus Escherichia) on day 10 post-weaning in faeces of C in comparison with A and B was detected. On day 21, the highest relative increase of beneficial lactobacilli was observed in B. Correlation analysis showed a positive correlation of C with the genera Turicibacter, Clostridium, Campylobacter, Dehalobacterium, Desulfuvibrio, Paludibacter and a negative correlation with the genera Prevotella, Blautia, Faecalibacterium, Lactobacillus, and Coprococcus. The opposite correlations with these genera were observed in the supplemented groups, especially in B. The results indicate that dietary supplementation with HNa and ZnO affects the microbial composition of faeces while maintaining good health and growth performance of ETEC infected weaned pigs.
