SILAGEM DE COPRODUTO DO MILHO E TOMATE, COM E SEM ADIÇÃO DE UREIA

Abstract

The experiment was carried out to evaluate the dry matter, pH, mineral matter, effluent losses, gas losses, total losses and recovery of dry matter, corn and tomato co - product silage. The experimental design was completely randomized with three levels of tomato co-product (0, 10 and 20% in natural matter) and two levels of urea (0 and 0.5% urea in natural matter), and three replications, totalizing eighteen silos. Eighteen mini silos were made in plastic buckets with a capacity of twenty liters, sealed with adhesive tape, weighed and stored in a covered area, for thirty days. There was no significant effect (P> 0.05) of urea levels and tomato levels, values for dry matter, mineral matter, pH. The levels of urea and tomato levels (P> 0.05), for gas losses, with 0.5% urea and 20% of tomato co-product was the treatment that presented the most losses. The quality of the silage is not compromised with the corn and tomato co-product, with the addition of up to 20% of tomato co-product and 0.5% of urea.
