Comparative Value of Napier and Sudan Grass When Used as Soiling Crops for Dairy Cows

The University of Hawaii, Honolulu

ABSTRACT

In four experiments comparing green Sudan with green Napier grass as a soiling crop fed to dairy cows, the former proved superior in each test on the basis of quantity of milk produced. Milk production averaged 8.7 per cent higher, and roughage consumption 7.2 per cent higher when Sudan grass was fed. The higher production on Sudan grass resulted from a greater nutrient intake because of greater palatability and higher nutritive value. Butter-fat tests were slightly higher when Napier grass was fed. Analyses of the grasses show that the Sudan grass was higher in protein, nitrogen-free extract, and total nutrients than Napier grass.
