<strong>Effect of addition of a bacteria isolated from sugarcane silage on the quality of the silage</strong> - DOI: 10.4025/actascianimsci.v30i3.1564

Abstract

Evaluating the effect of an inoculant containing a strain isolated from sugarcane silage on the chemical and microbiological characteristics of the silage of this forage was aimed. The treatments were silage without an inoculant and the strain identified as being of the species Lactobacillus buchneri. The forage was compacted in PVC silos. For the evaluation of the fermentation profile of the silages, the silos were opened with 0, 10, 32 and 70 days of fermentation and samples removed for determination of the content of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose and for evaluation of the population of lactic acid bacteria (LAB) and of yeasts for determination of pH. A reduction of DM contents from 33.02 to 25.99% and increased contents of NDF and ADF from 48.78 to 60.14% and from 28.42 to 38.61% respectively with the fermentation were observed. The LAB population was higher for the inoculated silage and the average population of yeasts and the pH values were lower. The inoculated population (4 log.cfu/g of forage) was insufficient to cause improvements or avoid losses during fermentation; nevertheless it is advisable, for it inhibited the growth of yeasts.
