A raspa de batata foi misturada ao capim-elefante (Pennisetum purpureum Schum.) na ensilagem. A colheita do capim-elefante
foi realizada manualmente após 80 dias do corte de uniformização a uma altura de 10 cm da superfÃcie do solo. As misturas capimelefante
e raspa de batata foram feitas nas seguintes proporções de matéria verde: 100 e 0%, 93 e 7%; 86 e 14%; 79 e 21%; 72 e 28%
de capim e raspa de batata, respectivamente. As plantas foram picadas em partÃculas de 2,0 a 3,0 cm de tamanho, ensiladas por 30 dias,
emsilos de PVC de dez centÃmetros de diâmetro e quarenta centÃmetros de altura. Foramavaliadas as porcentagens dematéria seca
(MS), valores de pH, perda de gases, perda de efluentes, proteÃna bruta (PB), fibra em detergente neutro (FDN), fibra em detergente
ácido (FDA) e digestibilidade in vitro da matéria seca (DIVMS), das silagens. O delineamento experimental empregado foi o
inteiramente casualizado, com quatro repetições. Concluiu-se que as silagens de capim-elefante com raspa de batata apresentaram
maiores porcentagens de MS, PB, valores de pH e DIVMS e menor porcentagem de perda de gases, perda de efluentes, FDN e FDA
na matéria seca com o aumento dos nÃveis de adição.
Potato scrapings were mixed with elephant grass (Pennisetum purpureum, Schum) in silage. Elephant grass was harvested
manually on the 80th day after leveling mowing had been done at a height of 10 cm from the soil surface. The mixtures of elephant grass
and potato scrapings were made in the in the following ratios of green matter: 100% and 0%; 93% and 7%; 86% and 14%; 79% and 21%;
and 72% and 28% of grass and potato scrapings, respectively. The plants were chopped in 2-3 cm particles and ensiled for 30 days in
10 cmwide x 40 cmhigh PVC silos. The following variables of the silagewere evaluated: percentage of drymatter (DM), pHvalues,
loss of gases, and of efluent, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro digestibility of
dry matter (IVDDM). The experimental design used was the completely randomized with four repetitions. It was concluded that
elephant grass silages added with potato scrapings exhibited higher percentages of DM and CP, higher values of pH, increase in the
IVDDM, and a lower percentage of loss of gases, loss of effluent, NDF and ADF in dry matter with increasing levels of addition.
