The effects of hungarian vetch (Vicia pannonica crantz.) and triticale (x triticosecale sp. wittmack) sown in different seed rates on feed value and ruminal degradability characteristics of nutrients

Abstract

The aim of the study was to determine forage yield, forage quality and in situ rumen degradation characteristics of Hungarian vetch (Vicia pannonica Crantz.) mixtures with triticale (x Triticosecale sp. Wittmack) in different seeding rates (HV, 75:25 HVT, 50:50 HVT, 25:75 HVT and T) during the flowering period of triticale. The research was carried out in the experimental lands of Gaziosmanpaşa University Agricultural Application and Research Center during the 2015-2016 vegetation period. Field experiment was designed as Randomized Block Design with 3 replicates. Besides, three rumen cannulated Karayaka rams (average 3 year old) were used to determine dry matter degradablity characteristics of pure and mixtures by using in situ method according to randomized design. The results that biomass and dry matter yield were not different among the groups, whereas the highest crude protein concentration (13.12%) was determined in the pure sown Hungarian vetch (P<0.01). In addition, the maximum crude protein yield was obtained from 75:25HVT group. In terms of effective dry matter digestibility, 50:50HVT experimental group, ED2, ED5 and ED8 (720.82, 706.1 and 692.64 g kg-1) was found to have the highest dry matter degradability. It was concluded that in case of mixed cultivation of Hungarian vetch and triticale, more digestible dry matter yield and crude protein yield can be obtained compared to pure cultivation. © 2020, Centenary University.
