Description

The systematic study of commercial preparations of fungal cellulases has been undertaken with the aim of determining the principal components and the contribution of each to the digestion of the plant cell wall. These enzymes, normally have three fold role-silage preservative by hydrolysing the cellulosic wall of plant material, cellulases make available fermentable sugars to the lactic bacteria. -Improvement of digestibility we can increase gain by 1 % of the dry matter in forage. - Improvement of intake if the animal digests more quickly his gut will empty more rapidly thus making it available sooner for a new intake of food. In the first part of this work (preliminary experiment), we tested on three vegetable substrates (two European and one tropical species), in silage conditions (pH, temp. etc.) how were working six cellulolytic enzymes. With the first experiment, we tryed to define the possibility of correlation between the enzyme activities found on vegetable substrates and the synthetic substrates. With the second serial of experiments, we tryed to define a correlation between the in vitro digestibility improvement with the coming out of neutral sugars in solution (Cs)- In conclusion, we can't demonstrate relationship between enzyme activities on synthetic and vegetable substrates. In the contrary, the in vitro digestibility vegetable improvement seem to be functions with the level of (Cs) neutral sugars in solution.
