Abstract:
In this study, nutrient contents, cell wall fractions, in vitro OMD and ME values of the heads, which remains in the field post-harvest, of 4 different hybrid sunflower (Helianthus annus L.) varieties that are planted commonly in Thrace Region, are compared. According to the findings, OM, CP, EE, CF and CA with NDF, ADF, ADL and cellulose contents in dry matter of sunflower varieties were respectively determined between 80.18-84.47%, 6.50-11.04%, 2.56-3.74%, 15.38-18.16% and 15.53-19.82% with 25.46-30.15%, 27.09-36.51%, 10.90-18.05% and 10.39-23.04%. In vitro OMD and ME values with Ca and P contents of varieties are respectively detected between 61.89-66.60% and 9.55-10.46 MJ/ kg DM with 2.15-3.22% and 0.07-0.30%. It has been observed that different varieties of sunflower heads have equivalent quality in comparison with the average quality forage and has relatively better quality in terms of some dry forage, which is used in ruminant nutrition, both in terms of in vitro digestibilities and ME values. In conclusion, when the forage problem in our country is considered, it is predicted that using sunflower heads as alternative to forage source will contribute to both the enterprise and national economy.
