The use of corn hybrid ROSS 195 for silage production in Central Non-Black Earth Region

Abstract

Relevance. This article presents the results of assessing the biochemical parameters and aerobic stability of silage prepared from the domestic early ripening corn hybrid Ross 195 (FAO 180) in the phase of milky-wax ripeness of the grain. Green mass was carried out during harvesting at Barybino LLC in August 2021.Methods. Ensiling was carried out in laboratory conditions of the Federal Williams Research Center of Forage Production & Agroecology in four variants of treatments with various preservatives in three replications of each.Results. Quality indicators were monitored after 30 and 60 days of conservation. Seven days after opening the containers during outdoor storage in silage variants with the addition of biological inoculants, a slight decrease in the concentration of lactic acid and an increase in acetic acid were determined. In silage with chemical preservative, the acid content remained at the same level. The results of assessing the dynamics of silage heating during outdoor storage allow us to conclude that the aerobic stability of the feed with biological inoculants is sufficient, versus control. At the same time, best preservation (over a period of up to 135 hours) the best aerobic stability of silage was obtained with chemical preservative, which was characterized by higher quality indicators in terms of the level of active acidity (pH 4.0–4.1), ammonia content (0.0055–0.0078%) and sugar, and the quantity and ratio of organic acids remained at the level determined at opening.
