Thank you for the chance of participating in this discussion group

In the section on Materials and Methods you state:
>The slurry came from a bio digester with the average
>retention time of 40 days. The input was pig manure
>from the pig fed with composite feeds mixed with
>30-60% of chicken manure after treatment"

Does this mean the chicken manure was added before digestion or after digestion.?
