Digestibilidad in situ de dietas con harina de nopal deshidratado conteniendo un preparado de enzimas fibrolíticas exógenas

Abstract: Se evaluó el efecto de un preparado de enzimas fibrolíticas exógenas (celulasas y xilanasas) en la degradabilidad in situ de la materia seca (DisMS), fibra detergente neutro (DFDNr) y fibra detergente ácido residual (DFDAr), en dietas altas o bajas en harina de nopal deshidratado. Se aplicaron concentraciones de 0, 1, 2 y 3 g de enzima por kilogramo de materia seca al inicio y 24 horas antes de la degradación in situ. Se determinó la concentración de ácidos grasos volátiles totales y de nitrógeno amoniacal a l… Show more

“…However, these values are lower than those published by Medina-Romo et al . [ 36 ], who reported 871 g/kg DMDis in a cattle diet containing 20% corn stover, 20% alfalfa hay, 26.7% commercial concentrate (18% CP), and 33.3% cactus meal. The discrepancies between this study and those reported by the aforementioned authors are related to the composition and efficiency of the rumen microbiota present in the cattle used for the in situ test [ 37 ] and the feed offered during the test [ 35 ].…”

“…The discrepancies between this study and those reported by the aforementioned authors are related to the composition and efficiency of the rumen microbiota present in the cattle used for the in situ test [ 37 ] and the feed offered during the test [ 35 ]. This is because in our study, the diet was based on 50% mango silage and 50% commercial feed (12% CP), and the previous studies [ 36 , 38 ] used to compare results fed the cattle with the same diet they evaluated.…”

“…Este grande problema da pecuária do Nordeste brasileiro, que é a oferta irregular de forragem, causa um grande prejuízo a este segmento da economia. A constância no aparecimento de anos secos faz da palma forrageira um alimento classificado como estratégico para esses períodos, quando o crescimento de outras forrageiras é limitado pelo baixo índice pluviométrico (CAVALCANTE, 2007;ROMO et al, 2006).…”
