Conclusion
The usage of purslane extract and virginiamycine antibiotic on boilers rations from 1 to 42 days may
increase weight gain and lead to better feed conversion. In this study a positive effect of purslane extract
on cholesterol and triglyceride concentration in the blood plasma of broilers was observed. Purslane
extract may be used as ingredient in chicks ration up to level of 20 ppm without harming weight gain and
feed conversion ratio of birds. However further studies are needed for more explanations.
