Abstract

A study was conducted was to increasing the protein level in putak by fermentation using fungiTrichoderma reesei. A laboratoryum experimental study was conducted using  factorial CompletelyRandomized Design 3 x 4 x 3. The main factor is were  inoculant levels of fungi T. reesei (T): 5,0; 7,5 and 10,0% (w/w),the level  and the second factor were of incubation time (W):  2; 3; and 4 days. Variables tested werecrude protein (CP), true protein (TP) and crude fiber (CF). The result showed that  treatment with 7.5% ofT.reesei  and incubation time for 4 days gawe the highest of crude and true protein level (20,60%)  from14,17% and 13,25% from 3,25%, and  lowest crude fiber 9,08% from 9,70%. Through fermentation of  fungiT.reesei can be increase the protein and decrease the fiber level of putak.

Abstract

Mycotoxins are toxic metabolites produced by some fungal species commonly found in food and feed,particularly in cereals. In intensive production systems, dairy cattle are commonly fed with cereal-richdiets and, consequently, are more exposed to micotoxins. Besides, such diet is often associated with ahigher risk of rumen acidosis which can also affect the performance and the helath of animal. In addition,the efficacy of microbial detoxification can be reduced during acidosis. For instance, some authors observeda decrease in the number of protozoa that are responsible for the degradation of some mycotoxins. Anotherconsequence of acidosis is the potential modification of ruminal absorption of mycotoxins, which until nowhas received scarce attention. Yeast Saccharomyces cerevisiae, probiotic additives have been shown toreduce the post-feeding drop in rumen pH and to increase the number of ruminal protozoa. This effect canbe positive in reducing the absorption and toxicity of mycotoxins in ruminantia.
