Resumen
Objective: to evaluate the chemical content [crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF)], and in vitro fermentative characteristics [biogas and CH4 cumulative production, metabolizable energy (ME), dry matter degradation (DMD) and neutral detergent fiber degradation (NDFD)] of three supplements based on overripe mango flour (HMD) and parota pod flour (HVP) through a grazing simulation in the laboratory.
Design/ Methodology/ Approach: supplements S1= 40% HMD + 60% HVP, S2= 60% HMD + 40% HVP, and S3= 80% HMD + 20% HVP; Treatments to simulate grazing T1 = 70% cobra grass (PCo) + 30% S1, T2 = 70% PCo + 30% S2, and T3 = 70% PCo + 30% S3.
Results: S3 had lower DMD, NDFD and ME (p ≤ 0.05). T1 had higher CP, DMD, NDFD and ME; and T3 showed lower NDF (p ≤ 0.05).
Limitations/ Implications of the study: this study was implemented in laboratory, so there were some climatological aspects and physiological issues of ruminants that were not considered.
Findings/ Conclusions: S1 improved the fermentative characteristics of cobra grass when grazing was lab simulated
