In situ ruminal degradability of savoy grass (Panicum maximun) silages with different levels of passion fruit (Passiflora edulis) peel inclusion.

Abstract:

(Four levels of passion fruit peel (PFP) 10, 20, 30, and 40% inclusion in Savoy grass silage were evaluated to determine dry matter (ISDMD), organic matter (ISOMD) and inorganic matter (ISOMD) in situ ruminal degradability). In situ degradability technique in 10 x 20 nylon bags, of 50±3 pore size at 0, 3, 6, 12, 24, 48, and 72 incubation hours for three 500±25 kg average weight bovine Brahman. A complete randomized block design was used. An increase in ISDMS disappearance as RCM (P< 0, 05) with 40% level of addition was evidenced. Values of 60.22% in 72 hours of incubation were obtained. ISOMD values showed no difference between treatments (P> 0.05) at 0, 3, and 48 incubation hours. Differences (P< 0.05) were found at 6, 12, 24, and 72 incubation hours. The highest ISOMD disappearance value was attained at 72 hours of incubation in T4 (59, 46%). DISMI showed no difference between treatments (P> 0.05) at 0, 3, 6, and 72 hours of incubation. However, we found a different behavior (P< 0.05) at 12, 24, and 48 hours of incubation. ISIMD at 72 hours of incubation was 69, 09 for T4. The highest percentage of degradation was attained with the addition of 40% RCM.
