Efecto de la adición de dos aditivos en ensilaje de maíz (Zea mays) sobre la calidad nutritiva del silo.

Abstract

The present investigation evaluated the comparative effect of the application of additives in corn silage (Zea mays) on the nutritional quality of the silo, the experimental work was carried out in the Jersey Chugllin Hatchery, which is located in the Chambo canton, Chimborazo province. To model the results, a Completely Random Design was used, where the treatments were additives (Josilac and Silo-mix) versus a control treatment, with 5 repetitions per treatment, the number of experimental units was 15 samples, 1 kg per each treatment, corresponding to the bromatological analyzes and organoleptic tests. The bromatological results of the corn silo showed that the best nutritional value concerning Protein 8.00% and Ethereal Extract 1.89% was for T2 (Silo-mix), in the percentage of Ashes, highly significant minor differences were recorded at (0.01) with T2 (Silo.mix) being the best with 8.09%; likewise at pH with 3.52% (T0). The organoleptic evaluation showed a better smell when using the Josilaj additive (T1) with 1 point, while the best texture score was achieved by adding the Silo-mix (T2) with a value of 1 point, being better to 2.00 (T0) and 2.00 of (T1). The treatment with the best cost-benefit was T1 (Josilac) with $ 1.50, meaning that for every dollar invested, a profit of 50 cents is expected, that is, 50%. It is concluded that several factors determine the quality and nutritional value of silage. The proper use of additives will be of great importance in the excellence of silage; therefore, it is recommended to apply additives in the silage such as Silo-mix or Josilac, since their response was optimal when improving the bromatological and organoleptic characteristics of the corn silo.
