The Effect of Addition Dry Sugar Beet Pulp in Triticale Silage on Silage Quality

The objective of this study was to evaluate the effect of two different levels of dry sugar beet pulp addition (DSBP) into fresh triticale harvested at milk stage on silage quality. At the first, the concentration of nutritional matters were determined in triticale harvested at milk and dough stage in the experiment. Then, DSBP was added to triticale harvested at milk stage at the levels of 0 (Control=C), 5% and 10% based on natural weight (W/W) and these silages were incubated about 3 months in plastic barrel (about 5 lt. in volume).Triticale harvested at dough stage (Without DSBP) was also ensiled and the silage quality was determined. Silage pH and volatile fatty acids (VFA) were determined as soon as silos opened, and the other nutritional matters analyzes were determined later on. CP content was determined on both wet and dry samples. Addition of DSBP into silage linearly increased DM content of silage (P<0.01) and the highest DM content was observed in triticale harvested at dough stage. It was observed that ash content of triticale harvested at dough stage had significantly lower compared with other silages (P<0.01). The content of CP, EE and NDF were numerically different, but it was observed statistically non-significant. Triticale harvested at dough stage had significantly lower ADF concentration compared with other groups (P<0.01). While the lowest pH (4.62) and the highest lactic acid concentration (131.73 g/kgDM) were observed in C+5%DSBP, the highest pH (5.59) and the lowest lactic acid concentration (29.51 g/kg DM) were determined in the triticale harvested at dough stage(P<0.01). Butyric acid concentration was the highest (9.99 g/kg DM) in control group, and the lowest in the dough stage group (1.82g/kg DM) and the difference of the groups was determined significant (P<0.01). In the study, the highest acetic acid value was15.53 g/kg DM in control, while the minimum value was in 6.59 g/kg DM in dough stage and the difference among the groups were significant (P<0.01). The highest propionic acid concentrations was3.02 g/kg DM) in dough stage, the minimum value was (1.18 g/kg DM) in C+10% DSBP and the differences among the groups were found to be significant at P<0.05 level. As a result, it was concluded that addition of 5% or 10% dry sugar beet pulp into triticale haven’t improved silage quality in this study. Therefore, it was concluded that appropriate studies should be carried out in order to solve the problem of compression especially in the construction of triticale silage by determining the appropriate harvesting period
