Digestibilidade aparente de dietas contendo silagem de cana-de-açúcar tratada com aditivo químico ou microbiano para cordeiros - DOI: 10.4025/actascianimsci.v29i1.260

Ensiling of sugar cane maycontribute to improve operational efficiency at farm level. However, the high ethanol levelfound in sugar cane ensiled without additive may reduce voluntary feed intake and mayaffect animal performance. This experiment was performed to evaluate the effects of freshsugar cane and sugar cane silage treated with microbial ( Lactobacillus buchneri ) or chemical(urea) additives on apparent digestibility of diets fed to lambs. Twelve Santa Ines lambs (49 ± 3 kg) were assigned to a complete randomized block design and fed a 50:50 (concentrate:roughage ratio) TMR. Experimental treatments were the roughage source: fresh sugar cane(FSC), sugar cane silage with L. buchneri (SCS + Lb), sugar cane silage with 1% urea (SCS1%) or sugar cane silage with 1.5% urea (SCS1.5%). NDF digestibility coefficient waslower (p 0.05) in nitrogen balance for all thecomparisons evaluated. The sugar cane ensiled improve NDF digestibility.
