Ensilaje de megathyrsus maximus jacq. con adición de harina de maíz, melaza y bacterias ácido-lácticas.

Abstract

Knowing the wide national distribution of the Megathyrsus maximus jacq. (saboya grass), the management that is given to it and on many times a poor use of it, this research was proposed with a view to evaluating the quality of this ensiled grass with the addition of corn flour, molasses and lactic acid bacteria (BAL on spanish) already that on many occasions, in the rainy season it is not fully exploited and in the dry season the meadows are so scarce and supplementation becomes necessary. 15 microsilos of 2 kg net each one were made where 3 levels of corn flour inclusion were tested (T1=10%, T2=15% and T3=20% of the silo) plus a control (T4) giving a total of 4 treatments with 3 repetitions each one. All of them contained molasses (6%) and lactic acid bacteria (300 ml t). Grass was fertilized in drench in 3 fractions. Harvest was made, it was chopped to no less than 2 cm, it was mixed with the ingredients according to the treatment proposed in each case and it was stored for 35 days after which each microsilo was opened and a 100g sample was obtained and sent to the laboratory for analysis of pH, dry matter (MS on spanish) and bromatology (crude protein, crude fiber, ash, ethereal extract, non-nitrogenous free extract). It was obtained that all treatments meet the minimum characteristics necessary to serve as ruminant feed, it was also seen that the inclusion of molasses, BAL and corn flour does influence the bromatological characteristics of the silos and that treatments T2 and T3 present the best bromatological characteristics. Likewise, it was found that the T1 treatment is the most profitable was the control.
