Abstract
Objective: To determine the bromatological and in vitro fermentative characteristics of supplements made with pod parota and pumpkin pulp shell.
Methodology: The supplements evaluated were C1 = 50% pumpkin pulp shell and 50% pod parota; C2 = 60% pumpkin pulp shell and 40% pod parota; C3 = 70% pumpkin pulp shell and 30% pod parota. In the supplements, dry matter (DM), crude protein (CP), ash (As), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), partial and accumulated production of biogas and methane were determined, biogas production kinetics, pH, total bacteria count, ammoniacal nitrogen, degradation of DM and NDF
Results: On average they quantified 15.88% of CP and 42.36% of NDF. C3 produced 4.53% more accumulated biogas than C2 (P<0.05). In the accumulated production of methane C2 and C3 did not show differences (P>0.05); but, they produced 7.31% less methane than C1 (P<0.05). In vitro degradations did not show differences between treatments (P>0.05).
Limitations on study: The best fermentative characteristics appear when the complement is worked with 60% pumpkin pulp shell.
Conclusions: Pumpkin pulp shell with pod parota are used to elaborate complements based on in vitro biogas production and degradations, so it can represent an alternative feeding of ruminants in the tropics.
