Nutrient profile, digestibility, and feeding value of common vetch (Vicia sativa) alone or intercropping with different forages

Abstract

The present study was conducted to assess the nutrient profile, digestibility and feeding values of common vetch alone or intercropping combinations with different cereal and legume forages in central district of Burdur, Türkiye. Approximately 2 kg fresh matter of common vetch alone or 9 different intercropping combinations was harvested from different locations. Nutrient composition and in vitro true dry matter digestibility were analyzed whereas feeding values were calculated. The study showed that intercropping largely decreased the crude protein of common vetch while an increase in fiber and carbohydrate fractions was noted except acid detergent fiber and acid detergent lignin that decreased in intercropping mixtures compared to common vetch alone. In addition, there was an increase in digestibility and feeding values in intercropping mixtures in comparison with common vetch alone. In conclusion, intercropping of common vetch with cereal forages improves the nutrient profile, in vitro digestibility, and feeding values despite a reduction in the crude protein content of intercropping mixtures compared to common vetch.
