Abstract :
The aim of this research was to determine the effect of different incubation times on in vitro dry matter (IVDMD) and NDF digestibility (IVNDFD) % of some common vetch cultivars, which grown under Cukurova conditions. In the research, the effect of IVDMD of different incubation times (12, 24, 36, 48 h) was investigated. The field experiment was carried out in the Cukurova Agriculture Research Experiment Area (Doğankent) in Adana, 2002-03 and 2003-04 as the winter season cropping. The field trials were established in a complete randomized block design with four replications. Özveren cv., developed by the related Institute through election methods, and along with Kubilay-82, Selçuk-99 and Uludağ cvs. formed the experimental material. The laboratory trials were established in a simple plot design with eight replications. According to the results of two-years average, Kubilay-82 cv. produced the highest dry matter yield (613 kg/da) and crude protein ratio (19.65%). In this study, in both years the values of in vitro dry matter digestability (IVDMD %) were significantly different between cultivars and between incubation times, while the values of nitrogen detergent fiber (NDF) differed between incubation times for both years, but only differed between cultivars in the first year. The lowest in vitro DMD and highest in vitro NDF were reached at 12 h, while the highest IVTD and the lowest in vitro NDF were attained at 48 h.
