Different flora and pH were evaluated over a 30 day period. Sugarcane blunting was fermented under different conditions: using native flora (control), using specific goat probiotics, including Lactobacillus reuteri DDL19 (Treatment Nº1), Lactobacillus alimentarius DDL 48 (Treatment Nº2), Enterococcus faecium DDE 39 (Treatment Nº3), Bifidobacterium bifidum DDBA (Treatment Nº4) and a probiotic mixture containing equal amounts of the four probiotics. The ensilages were evaluated microbiologically and then administered to different batches of 6 animals each immediately after weaning. The dominant bacterial populations in the gastrointestinal tract (GIT) of the goats were evaluated by studying the faeces. We evaluated the five different treatments during three consecutive periods of seven days each (ingest-repose), starting immediately after weaning. After the third ingestion period, the results indicated that a combination of Lactobacillus reuteri DDL19, Lactobacillus alimentarius DDL 48, Enterococcus faecium DDE 39 and Bifidobacterium bifidum DDBA was able to diminish coliforms and enhance the beneficial Bifidobacterium and lactic acid bacteria by at least one logarithmic unit with respect to the control. Further, the incidence of diarrhoea in this experimental group was lower than the control group. The sugarcane residual was ingested without difficulty by goats as a supplemental food. More importantly, our results support the development of alternative feed for animal use during the dry season, which is characterised by deficient and poor pastures. This is of particular interest because the dry season in north-western Argentina coincides with the sugarcane harvest.
