Продуктивность и питательность травосмесей в зависимости от видового состава в условиях Приморского края

Lolium multiflorum Lang. is one of the promising annual crops for forage production. The effect of Lolium multiflorum Lang. on the yield and forage quality when used as part of the grass mix Avena sativa + Vicia sativa and Pisum sativium was studied. The effectiveness of Lolium multiflorum Lang. in grass mixes and the forage quality was evaluated. The research goal was to reveal the possibility of increasing forage quality and herbage yield caused by including Lolium multiflorum Lang. into the mixes of annual grasses. The following mixes were studied: Avena sativa + Vicia sativa (control), Avena sativa + Vicia sativa + Lolium multiflorum Lang., Avena sativa + Vicia sativa + Pisum sativum + Lolium multiflorum Lang., Avena sativa + Vicia sativa + Pisum sativum, Avena sativa + Pisum sativum. The mixes were harvesting at oat milk-ripe stage (1st cutting) and at ryegrass flowering beginning (2nd cutting). Three-four-component mixes with Lolium multiflorum Lang. included revealed the greatest yields of digestive protein, feed units and available energy. The forage of all mix variants was well protein-balanced with 120 g and more of digestible protein per 1 feed unit. The greatest milk yield per 1 ha (12.5 t) was obtained when feeding cows with the following grass mix: Avena sativa + Vicia sativa + Pisum sativum + Lolium multiflorum Lang. Besides, ryegrass extends the use of green forage chain system. Therefore, Lolium multiflorum Lang. offers great opportunities for forage production in the Primorskiy Region enabling to supply cattle breeding with high quality forage from end of June to early October.
