“As a reminder, Leafy corn varieties are distinguished by ‘40% more leaf area: on average, this translates to four additional leaves per plant, all located above the ear, and wider leaves (1 to 2 cm wider than conventional varieties),’” explains Jérémy Bonte of Semental.
“The additional leaves increase the fiber content (NDF) by 2 to 3 percentage points compared to conventional varieties. This increase is accompanied by improved fiber digestibility, with dNDF or DMOna levels that are 2 to 3 percentage points higher.” Ultimately , this results in more energy from the fiber.
“Visually, the ear also stands out, with 100% dented, floury kernels and ears that produce 80 to 200 more kernels than the control varieties,” notes Jérémy Bonte. Based on initial 2025 analyses, the starch content of Leafy corn is 5 to 6 percentage points lower,“but its degradability is 15 to 20 percentage points higher. Thus, a Leafy variety with 25% starch will provide as much nutritional value for the animal as a conventional variety with 31% .” He also points out that a starchy variety allows for faster silo opening.
The lineup available for the 2026 planting season includes early-maturing varieties with FAO ratings ranging from 260 to 500, comprising nine varieties: Anzac, Apgar, Botha, Kenora, Beauport, AS1445, Dawson, Belleville, and Admirasil. New varieties are expected in 2027.
