Extract

Pomegranate by-products (peel and seed) contain about 40-45 percent of the fruit’s weight. The rind of the fruit (peel),when dried, is brown outside, yellow inside, hard, dry, brittle, in irregular fragments, inodorous, and with a very astringent, somewhat bitter taste. Analysis of pomegranate peel (PP) is shown that it contains 18.8 percent of tannin, 17.1 of mucilage, 10.8 of extractive matter, 30 of lignin, a trace of resin, and 29.9 of moisture. However, little information is available on PP nutritive value for ruminants. It is poor in protein and rich in tannins. Tannins components of the peel prevents its optimal use. The objective of this experiment was to evaluate the effect of different levels of urea (U) on in vitro gas production with and without added polyvinylpolypyrrolidone (PVP) to ensiled pomegranate peel (EPP).
