Abstract

SANCHEZ LAINO, Adolfo et al. In situ nutritional assessment of diets with passion fruit meal (Passiflora edulis) as replacement of maize (Zea mays). Rev. investig. vet. Perú [online]. 2019, vol.30, n.1, pp.149-157. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v30i1.14438.

The parameters of in situ ruminal degradation of passion fruit meal (Passiflora edulis) included in diets for ruminants as replacement of maize were studied.Arandomized complete block design was applied with four treatments (0, 10, 20 and 30% [T, T2, T3 and T4, respectively] of inclusion of passion fruit meal), three blocks (rumen-fistulated bovine) and seven incubation times (0, 3, 6, 12, 24, 48 and 72 hours). The differences between means were established using the Tukey test (p<0.05). T1 and T2 showed the highest (p<0.05) degradability of dry matter and organic matter at 48 and 72 h of incubation, respectively, while neutral detergent fibre and acid detergent fibre had a greater degradability in T4 and T3 at 48 and 72 h of incubation. The ruminal kinetics parameters were not significant in any of the variables evaluated. The results show that passion fruit meal can be used to replace maize up to 10% in diets for ruminants in the Ecuadorian littoral.

Keywords : ruminal degradability; agro-industrial waste; ruminant feeding; ruminal kinetic.
