"Degradabilidad y cinética ruminal in vitrio de residuos agroindustriales provenientes de cáscara de plátano (Musa paradisiaca), fréjol gandul (Cajanus cajan), maracuyá (Passiflora edulis), lodo de palma (Elaeis guineensis), usadas en la alimentación de rumiantes".

The objective of the research was to determine the in vitro ruminal degradability and kinetics of agro industrial residues from banana peels (Musa paradisiaca), pigeon peas (Cajanus cajan), passion fruit (Passiflora edulis), palm mud (Elaeis guineensis). Four treatments were evaluated: (T1 Banana shell; T2 Pigeon peas shell; T3 Passion fruit shell; T4 Palm mud rejection) and three repetitions. The degradability and kinetics of dry matter (DM) were evaluated. The research was carried out in the Rumiology Laboratory, “La María” Experimental Campus. The in vitro dry matter degradability (DIVMS) of agro industrial residues from bean peel, pigeon peel, passion fruit, banana and palm mud rejection presented the best result on T1, which is composed of banana peel (0 hours 25.43%, 3 hours 27.69%, 6 hours 46.14%, 12 hours 46.69%, 24 hours 57.07%, 48 hours 71.65%, 72 hours 72.9%). In the degradation kinetics, the soluble fraction (A) (31.30%) was higher (P <0.05) in the T3 peel of passion fruit, followed in a descending way the T4 rejection of palm mud (23.78%), T1 peel of banana (22.82%) and T2 peel bean pigeon peel (11.08%). The soluble potentially degradable fraction was higher (P <0.05) in banana peel T1 (55.53%), consecutively in T4, T3 and T2 (45.57%; 38.85%; and 26.92%, respectively). The constant or degradation rate of fraction B (c), which is expressed in% / hour, was higher (P <0.05) in T4 palm mud rejection (0.06), followed by T3 (0.05), T1 (0.05) and the T2 (0.02). the mean values of the maximum potential degradability of dry matter (A + B) do not differ (P> 0.05) between the treatments compared with degradation rates of 57.03% to 78.34%. The degradability of the dry matter was higher in all treatments T1 (banana peel), T3 (passion fruit peel) and T4 (palm mud rejection), indicating high nutritional values, being an efficient and environmentally acceptable way of disposing of feed to sustain the productivity of ruminants in the dry season. The kinetics of in vitro degradation and the ruminal passage of the nutritional fractions of the DM determined better efficiency for the T1 treatment based on banana peel. Key word: degradability, kinetics, passion fruit peel, banana peel, pigeon peel, palm mud.
