The determination of feeding value of dried seedless olive pulp with in vivo digestion method

The aim of this research, adding economical value to olive cake and olive mill waste water which is by-product of olive oil processing causing environmental pollution if it isn't utilized. In order to determine the content of acquired seedless dry olive pulp (SDOP) from different production systems (with 2 and 3 phase), like crude nutrients, the amount of total phenolic matter, antioxidant capacity and feed value, and rumen parameters, the animals fed by SDOP. Research has been conducted in two stages. In the first stage, crude nutrients of 2 and 3 phased SDOP are determined. The values of mean dry matter (DM), crude ash (CA), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent insoluble fiber (NDF), acid detergent insoluble fiber (ADF) and acid detergent insoluble lignin (ADL) in 2 phased SDOP, are determined respectively as 88,42%, 11,16%, 77,26%, 7,50%, 15,63%, 46,77%, 42,92%, 16,38%. The values of sodium (Na), potassium (K) and calcium (Ca) are determined as 2,19%, 1,06%, 0,44%. The composition of 2 phased SDOP's important oil acid contains, 13,65% palmitic acid (PA), 2,08% stearic acid(SA), 67,46% oleic acid(OA), 11,76% linoleic acid (LA) and 0,64% α-linoleic acid (α-LA).Total phenolic matter of 2 phased SDOP is, 423,28 mg per 100 g of the sample and the antioxidant capacity is determined as 15,80%. The values of DM, CA, OM, CP, EE, NDF, ADF and ADL in 3 phased SDOP, are determined respectively as 88,15%, 3,69%, 84,46%, 9,03%, 17,10%, 61,46%, 52,27%, 19,90%. The values of Na, K and Ca are determined as 0,08%, 1,05%, 0,34%. The composition of 3 phased SDOP's important oil acid contains, 10,66% PA, 2,07% SA, 54,71% OA, 11,05% LA and 0,74% α-LA. Total phenolic matter of 2 phased SDOP is, 522,72 mg per 100 g of the sample and the antioxidant capacity is determined as 28,45%. In the second stage of the research, two phased in vivo digestion trial has been applied. The digestion degrees of average DM, OM, CP, EE, NDF, ADF in 2 phased SDOP's are determined respectively as 38,89%, 34,39%, 13,23%, 82,61%, 59,63% and 37,18%. 3 phased SDOP's values of DM, OM, CP, EE, NDF and ADF, are determined respectively as 22,05%, 20,93%, 11,04%, 81,84%, 58,75% ve 29,72%. Also pH, ammoniacal nitrogen (NH3-N) and essential oil acid values has been researched of rumen fluid gotten from animals.
