this experiment was conducted to evaluate the effects of dietary salvia mirzayanii supplementation on performance, carcass characteristics, internal organs and cecal microbial population in broilers. a total of 200, one-day-old broiler chicks (ross 308) were fed five experimental diets containing different levels of s. mirzayanii (zero, 0.25, 0.50, 0.75 and one percent of diet) until 42 days of...

The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d(-1)) were compared with untreated control cows (CON, 0 mg d(-1)) with respect to the effects of monensin on the production of three greenhouse gases (GHG), methane (CH(4)), nitrous oxide (N(2)O), a...

Sequencing of DNA fragments (e.g., ITS, 16S, 18S, particular genes, and molecular markers) is increasingly required in studies on microbial diversity, microbial genetic population and phylogeny, sequencing of alleles, and searching for SNPs, among others. The cost of obtaining these DNAs, in quantity and quality for sequencing, is high as it involves special kits to recover DNA from gel after P...
