The Effect of Formaldehyde and Blood Treatments of Hazelnut Meal on the Degradation Characteristics and Effective Degradability in Rumen
2 Kafkas Üniversitesi Veteriner Fakültesi Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı-KARS - This study was carried out to evaluate the effects of formaldehyde and blood treatments of hazelnut meal on the degradation characteristics and effective degradability of dry matter (DM), organic matter (OM) and crude protein (CP) in rumen. Hazelnut meal treated with 0.4, 0.6, 0.8 ve 1 g formaldehyde / 100 g CP; 0.5, 0.75, 1.5 and 2 l whole blood / kg DM.
Three adult rumen fistulated merino rams were used in this study. Samples were incubated in the rumen for 2, 4, 8, 16, 24 and 48 h. Rumen degradability characteristics and effective degradability values of DM, OM and CP of hazelnut meal samples were determined.
Formaldehyde treatment of hazelnut meal at the level of 0.4 and 0.6 g / 100 g CP increased the amount of rapidly soluble protein by 21.24 % and 33.49 %, respectively. However the protein which in time will degrade decreased by 16.04 % and 12.14 %, respectively and maximum potential degradability of protein in rumen was not affected. Treating meal with different levels of blood increased the amount of rapidly soluble protein by 24.96 - 54.73 %, reduced the amount of protein which in time will degrade by 19.39 - 29.44 % and therefore maximum potential degradability of protein in rumen was not affected. Treating hazelnut meal with different amounts of formaldehyde or blood did not affect degradability of DM, OM and CP after 48 h incubation in rumen.
As a conclusion, the protection of hazelnut meal treated with formaldehyde or blood from rumen fermentation was found to be ineffective.
