Effect of zinc phosphate-based nanoparticles on culturable bacteria in pig

Popis výsledku v původním jazyce

High doses of zinc oxide (ZnO) added to the diet for piglets for the prevention of diarrhoea can increase the growth rate and contaminate the farms and the surrounding environment. Therefore, there is a need to find a replacement of dietary ZnO with an equally effective alternative. In this study, we compared the effect of two formulations of zinc phosphate-based nanoparticles (ZnA and ZnC NPs) on growth performance. A total of 100 weaned piglets were divided into 10 equal groups with the base diet (control) or the base diet supplemented with ZnA, ZnC, or ZnO at concentrations 500, 1000, and 2000 mg Zn per kilogram of diet. Supplements were given to animals for 10 days. Fecal samples were collected on day 0, 5, 10 and 20. At the end of the treatment (day 10). Comparing to that of control, the significantly higher piglet weight gain was observed in all piglet groups fed with ZnA (P &lt; 0.05). Differences in the total aerobic bacteria and coliform counts in piglet feces after NPs supplementation compared to that ofcontrol and ZnO groups were also found (P &lt; 0.05). The majority of aerobic culturable bacteria from the feces represented Escherichia (28.57-47.62%), Enterococcus (3.85-35.71%), and Streptococcus (3.70-42.31%) spp.
