Pearl millet silage produced equal amounts of milk with higher milkfat levels than corn silage in a dairy feeding trial at McGill University in Quebec.
Twenty Holstein cows were used in an experiment aimed at determining the feeding value of pearl millet silage relative to corn silage. Two rations were formulated with a 53:47 forage-to-concentrate ratio, with one of the two silages comprising 67% of the forage in each diet. Compared to corn silage, the pearl millet silage contained higher crude protein (13.0 vs. 9.4%), NDF (66.9 vs. 40.7%) and ADF (38.8 vs. 23.9%).
Dietary treatments had no effect on dry matter intake, although cows fed millet silage consumed more NDF than the other group. Silage type didn’t affect milk production, which averaged 84 lbs/day, but milk from cows fed millet silage tested 4.17% fat vs. 3.78% for milk from cows fed corn silage.
“Because of increased milk fat concentration, cows fed pearl millet silage produced more energy-corrected milk than did cows fed corn silage,” the researchers report.
