Resumen
The physic-chemical characterization of concentrated vinasse from the Havana Club rum factory of San Jos? de las Lajas municipality, Mayabeque province, was conducted to assess its potentialities as animal feeding and contribute, at the same time, with the environment.
The vinasse samplings were conducted in the storing tanks of the Swine Unit and the Ruminants Production Center ?Atrevido? from the Institute of Animal Science. The proximal analysis, pH, specific weight, reducing sugars and amino acids composition were considered for the physic-chemical composition. A descriptive analysis with five repetitions was applied for processing the data. The microbiological analysis was also carried out to know the presence of polluting microorganisms. The values of pH and specific weight of the product ranged between 3.92-4.20 and 1.08-1.13 gL-1, respectively. The DM content varied between 21-29 %, while that of ash remained between 23-25 % DM and the reducing sugars fluctuated from 3.69 to 4.95 %. The mean mineral composition concentration of most elements (%) calcium, 3.54; magnesium, 1.20; phosphorous, 0.26; potassium, 6.78 and sodium, 1.71 was within the required ranges for different animal species. The CP levels oscillated between 11-14 % of DM, there was high proportion of glutamic acid, lysine and aspartic acid in the amino
acidic profile. No polluting microorganisms were found in the product. The results of the physic-chemical characterization of vinasse showed
the potentialities of this by-product as animal feeding. Further physiological and of productive performance studies are recommended to clear up the effects of this product on the different species and animal categories.
Key words: vinasse, chemical composition, animal feeding, environment.
