The effects of high dose of two manganese supplements (organic and inorganic) on the rumen microbial ecosystem

The effects of high dose of two manganese supplements (organic and inorganic) on the rumen microbial ecosystem after four months of treatment of 18 lambs divided into three treatment groups were studied. We examined the enzyme activities (α-amylase, xylanase, and carboxymethyl cellulase), total and differential microscopic counts of rumen ciliates, total microscopic counts of bacteria, and fingerprinting pattern of the eubacterial and ciliates population analyzed by PCR-DGGE

Evaluation of population variability of DGGE profiles and microscopic counts of lamb rumen eubacteria and ciliates with two manganese supplements.
