The proportion of components in field pea and spring triticale mixtures and harvest stage affect crude fiber content and forage digestibility | The proportion of components in field pea and spring triticale mixtures and harvest stage affect crude fiber content and forage digestibility

英语. The work presents results of a study conducted in 2016–2018 to determine the effect of component share in the mixture and harvest stage on concentration of crude fibre and its fractions as well as digestibility of field pea/spring triticale mixtures. The following two factors were examined in a field experiment: factor I – component share in a mixture: field pea in pure stand 100%, spring triticale in pure stand 100%, field pea 75% + spring triticale 25%, field pea 50% + spring triticale 50%, field pea 25% + spring triticale 75%; factor II – harvest stage: field pea flowering stage (BBCH 65), field pea flat green pod stage (BBCH 79). The concentration of crude fibre and its fractions (NDF, ADF, ADL) were determined in the dry matter in addition to dry matter digestibility and organic matter digestibility. The lowest content of crude fiber and its fractions, among the mixtures, was revealed in the mixture with the share of components of pea and spring triticale 75% + 25% and 50% + 50%, respectively. Harvesting mixtures at a later stage caused an increase in crude fiber content and its fraction in dry matter. The superior dry matter digestibility and organic matter digestibility were found for field pea and field pea/spring triticale mixtures containing 75% + 25% and 50% + 50% of the respective components and harvested at the stage of field pea flowering.
