the effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (dm) and nutrient digestibility of corn silage wereexamined. whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: propionibacterium acidipropionici plus l...

bioavailability of three rumen protected methionine (met) sources with different protection methods (mepron® m85, evonik industries, germany; methioplus®, soda nutrition, italy and methilock®, tehrandaneh co. iran) were evaluated in 2 experiments with 6 canulated non-lactating holstein cows. in experiment 1, the ruminal in situ and mobile bag techniques were used for assessing ruminal degradabi...

in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...

This study aims to estimate the degradation process of polylactide (PLA) in natural aqueous environments. The biological PLA took place Baltic Sea and pond over a period 1 16 months. characteristic abiotic parameters both environments were monitored during incubation time, their influence on was discussed. changes weight, chemical structure, mechanical properties surface morphology investigated...
