Abstract

This study was conducted to investigate the effect of mixture types which consist of different species on the dry matter(DM) yield, botanical composition and forage quality. The experimental design includes three mixture types: Conventional mixtures(orchardgrass 50% + tall fescue 20% + perennial ryegrass 10% + Kentucky bluegrass 10% + white clover 10%), complex mixtures(orchardgrass 40% + tall fescue 20% + perennial ryegrass 10% + Kentucky bluegrass 10% + redtop 10% + alfalfa 5% + red clover 5%) and simple mixtures(orchardgrass 80% + red clover 20%). The DM yield was higher in conventional mixtures(13,070kg/ha) than in other mixtures(p<0.05). In the chemical composition and dry matter digestibility, there was significant difference among mixtures. Crude protein content and dry matter digestibility were higher in complex mixtures than in other mixtures(p<0.05). But, the content of fibrous constituents was higher in conventional mixtures than in other mixtures. The yield of crude protein dry matter(CPDM) and digestible dry matter(DDM) were higher in complex mixtures than in other mixtures. In this experiment, DM yields and quality of mixture types were observed significant difference. therefore, the complex mixtures which combined various species were more effective in enhancing the dry matter digestibility(DMD) and digestible dry matter(DDM) yield.
