<b>Fiber fraction ruminal degradation of corn silage without spikes with sugar cane and manioc pulp</b> - DOI: 10.4025/actascianimsci.v28i4.606

Abstract

This study aimed to evaluate the ruminal degradation of corn silages without spikes (CSWS), with addit ion of sugar cane (SC) and dry manioc pulp (DMW), compared to corn silage (CS). The feeds were ensiled with (WI) and without (IF) inoculants - Lactobacillus plantarum and L. paracasei ssp. paracasei. The following fractions were studied: water soluble (A), potentially degradable (B), non degradable (C), fraction B degradable ratio (c); effective (ED) and potential (PD) degradability. The treatments evaluated were: T1 (CSWS + 20% SC -IF); T2 (CSWS + 20% SC-WI); T3 (CSWS + 35% SC-IF); T4 (CSWS + 35% SC -WI); T5 (CSWS + 20% DMW-IF); T6 (CSWS + 20% DMW-WI); T7 (CSWS + 35% DMW -IF); T8 (CSWS + 35% DMW-WI); T9 (CS-WI) and T10 (CS-IF). The average differences were compared on a completely randomized model. Higher (p<0.05) B fractions for FDN were observed for T7 (B= 7 4.8%), T8 (B= 70.2%), T6 (B= 66.2%) and where the low sugar cane level was added on silages, that is, T2 (B= 65.0%). No differences (p >0.05) were observed between ADF C fraction for T3 (C= 20.7%), T4 (C= 22.6%), T9 (C= 22.7%) and T10 (C= 24.0%). Results in dicate the possibility to include DMW on corn silage, instead of green spikes, to the level of 35%.
