Study of chemical composition, digestibility and process of protein and dry matter degradability of eggplant (Solanum melongena) using In situ technique

At the first, chemical composition of testing samples were detected by approximate analysis and 3 Kordi steers were fistulated for degradability experiment. Dry matter and protein degradability of samples were determined with nylon bag technique for 0, 4, 8, 16, 24, 48, 72 and 96 hours after rumen incubation. Gas volume (ml / 200 mg DM) were measured after 0, 4, 8, 12, 24, 48, 72 and 96 hours of incubation. Digestibility of dry matter (DMD), organic matter (OMD) and drymatter in organic matter (DOMD) were measured with tilly and tery (1963) technique. Soluble sugares of samples were measured too. Results of approximate analysis were showed that amount of crude protein, NDF, ADF and soluble sugares of sample were 12.6, 57.6, 47 and 3.16 percentage respectively. Dry matter and protein degradability of auberjine were 62.80 and 91.50 percentage respectively. volume of gas production after 24 hours incubation was 32.1 (ml / 200 mg DM). results of this research were showed that orskov and McDonald equation for expression of degradability of feeds in nylon bags technique have a good correlation with gas volume production in feed evaluation.
