Determination of the Varying of Vegetation Harvested Hungarian Vetch and Wheat Mixture on Nutrient Content, Degradation Kinetics, in vitro Digestibility and Relative Feed Value

Abstract

Hungarian vetch intercropped with wheat (50%:50%) planted at dryland in Autumn, and were harvested 7 times at 1 wk intervals throughout mid June and late July. The aim of study was to determined the effects of varying harvested of the mixture on nutrient content,in vitro digestibility, relative feed value (RFV) and rumen degradation kinetics. While harvest effect did not differ hay of Hungarian vetch + wheat on dry matter (DM), ash and organic matter, NDF and ADF ratios increased, and the crude protein ratios increased up to July, 20 degradabilities were determined between 30.10-53.24% and its were statistically decreased with increasing maturity (P<0.01). Forage yield 1385-1643 kg/da, dry herbage yield 363-654 kg/da and dry matter yield 344-621 kg/da were throughout harvesting period.Forage yield increased significantly as from July, 6 the harvesting stage (P<0.01). in vitro dry matter digestibilities of the mixtures hay declined rapidly because of maturity from first harvesting to end harvesting (P<0.01). RFV of the mixtures were determined between 106-180. The DM degradabilities in rumen decreased with delaying harvest of the mixtures. Degradation rates of the mixtures were not statistically founded between 0.015-0.033 h-1. Effective DM degradabilities were determined between 30.10-53.24% and its were statistically decreased with increasing maturity (P<0.01). In conclusion, according to investigated parameters 30.10-36.68% of DM of Hungarian vetch and wheat mixtures or milk stage of wheat seemed to be the best harvesting stage for forage.

Effects of Mixture Ratio and Row Spacing in Hungarian Vetch (Vicia pannonica Crantz.) and Annual Ryegrass (Lolium multiflorum Lam.) Intercropping Sys

“…In the mixtures, decreased CPYs were observed with decreasing HV ratios. While most researchers found the highest CPRs and yields with 60% or higher HV in the mixture (Albayrak et al 2004;Karadag and Buyukburc 2004;Balabanli and Turk 2006;Lithourgidis et al 2006;Bingol et al 2007;Yolcu et al 2009;Budak et al 2011), some others observed the highest yields in equal mixtures (50%-50%) (Basbag et al 1999;Gunduz 2010;Aksoy and Nursoy 2010) and 60% cereal mixtures (Bedir 2010). HV contains remarkably more CP than grasses and its mixtures with grasses contain more CP than the sole sowing of AR.…”

“…While several researchers reported the highest green herbage and hay yields of HV mixtures as 66%-87.5% (Albayrak et al 2004;Yolcu et al 2009;Budak et al 2011;Koc et al 2013), others reported the highest values for equivalent rate mixtures (50%-50%) (Karadag and Buyukburc 2004;Gunduz 2010;Aksoy and Nursoy 2010;Nadeem et al 2010). Contrary to other researches, Balabanli and Turk (2006), Tuna and Orak (2007), and Bedir (2010) reported the highest yield values for cereals mixture rates of 75%-80%.…”

“…Albayrak et al (2011) determined RFV, NDF, and ADF rates for HV, respectively, as 142%, 42%, and 33%. Yolcu et al (2009) found the NDF and ADF of different mixtures as 57% and 33%, respectively; Aksoy and Nursoy (2010) reported these values of HV-wheat mixture as 43% and 34%, respectively, and Bingol et al (2007) reported the values in HV-barley mixtures as 57% and 30%, respectively.…”

Effects of various inulin levels on in vitro digestibility of corn silage, perennial ryegrass (<i>Lolium perenne</i> L.) and common vetch (<i>Vicia sativa</i> L.)/oat (<i>Avena sativa</i> L.) hay

“…The IVTD DM values showed no significant differences (P >0.05) among the control and treatment groups. The in vitro dry matter digestibility levels of common vetch/wheat hay harvested at different times were in the range of 57.37 to 70.48% (Aksoy & Nursoy, 2010). The reported IVTD DM values for common vetch were 58.06 % and 74.95% in 2003and 2004, respectively (Yucel & Ayasan, 2010.…”

Farklı Tohum Oranlarında Ekilen Macar Fiği (Vicia Pannonica Crantz.) ve Tritikalenin (Xtriticosecale Wittmack) Yem Değeri ve Rumende Parçalanabilirlik Özellikleri Üzerine Etkileri

“…With mixed cultivation, harvesting becomes easier ( Kusvuran et al, 2014). It has been reported by the researchers that the most suitable form of time in the plantings mixed with the wheat crops is 30-36% of the dry matter of the plant mixtures or in the milk stage of wheat (Aksoy and Nursoy, 2010). On the other hand, triticale plant is a hybrid of wheat and rye and has been obtained as a result of long-term improvement studies in many countries.…”
