Abstract EN
The effects of polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) on in vitro gas production characteristics, organic matter digestibility (OMD), and metabolizable energy (ME) contents of some grape yield byproducts were investigated.
The gas production was recorded after 2, 4, 6, 8, 12, 16, 24, 36, and 48 h of incubation.
The gas production profiles in triplicate fitted with equation Y = A (1 – e−ct).
The data was analyzed using completely randomized design.
Total phenol (TP) and total tannin (TT) contents were highest for raisin waste (RW).
The TP content (g/kg DM) ranged from 30.1 in grape pomace (GP) to 96.3 in RW, which also had the higher TT (72.1 g/kg DM).
The potential gas production (a + b) of DGB, GP, and RW were 239.43, 263.49, and 208.22 mL/g DM, respectively.
In the absence of PEG and PVP, rate constant of gas production (c) for GP was highest among the feedstuffs (0.1073 mL/h), but in presence of PEG or PVP, RW had highest fraction (c) among the feedstuffs.
Addition of PEG and PVP inactivated effects of tannins and increased gas production, ME, NE1, OMD, and VFA in grape yield byproducts.
Addition of PEG and PVP could overcome adverse effects of tannins on nutrient availability as indicated by gas production parameters.
