A kenaf variety developed at Mississippi State University outperformed two other varieties in a silage trial at Kangwon National University in South Korea.
Whitten was compared to Tainung-a and Everglade in research evaluating the tall-growing annual fiber crop as feed for dairy and beef cattle. The three varieties were harvested Aug. 3, Aug. 15 and Aug. 28, and their yield and silage quality were compared.
All treatments produced silage with a pH below 4.0, which is suitable for stable storage, the researchers report. They say kenaf shows promise as silage for ruminants – especially Whitten, which had the highest dry matter yield and lowest fiber content at all harvest dates.
