Silagem de capim-piatã (Brachiaria brizanta) utilizando níveis de resíduo de fibra de Curauá (Ananas Erectifolius L.B. Smith)

Abstract

O trabalho buscou avaliar as características fermentativas, análise sensorial e estabilidade aeróbia de silagens de capim-piatã com adição de resíduo de fibra de curauá. Realizou-se o experimento no laboratório de Bromatologia da Universidade Federal do Oeste do Pará, ensilou-se o capim-piatã aos 43 dias de rebrota, com inclusão de 0; 2,5; 5 e 7,5% de resíduo de fibra de curauá. Utilizou-se delineamento inteiramente casualizado com quatro tratamentos e 5 repetições. Após 45 dias, os silos foram abertos e procedeu-se à análise sensorial e retiradas de amostras para análise do nitrogênio amoniacal, pH, MS, PMS, PG, RMS e estabilidade aeróbia. A inclusão dos resíduos de fibra de curauá promoveu aumentos lineares de MS (P<0,05). Houve diferença significativa para as variáveis de PMS, PG, RMS, N-NH3/N-TOTAL. A inclusão do resíduo reduziu de forma linear as PG (P<0,05), promoveu aumento no teor de N-NH3/N- TOTAL (P<0,05) nos tratamentos com 0; 2,5 e 5% de adição do resíduo de fibra de curauá e reduziu no tratamento com 7,5%. Houve aumento nos valores de pH (P<0,05). Com relação à temperatura (P<0,05), todas as silagens apresentaram valores de máximas entre 27,8oC e 28oC. Apenas o tratamento com 2,5% de resíduo de curauá apresentou quebra de estabilidade. As silagens analisadas apresentaram pouca deterioração aeróbia. A inclusão do resíduo de fibra de curauá na silagem de capim-piatã contribuiu para o aumento da temperatura e do pH das silagens e as perdas de N-NH3.
