The use of Azolla in lactating cows


, : The use of Azolla in lactating cows. Iranian Journal of Agricultural Sciences 23(1): 47-56

The aim of this study was to use Azolla, an aquatic fern, as a feedstuff in the ration of lactating cows. Using a crossover design, 16 lactating cows were selected and allocated into 4 blocks as a 4 x 4 Latin-square design. The cows were individually given 4 rations, including maize meal, silage and concentrates. The concentrates contained 0 (A), 15 (B), 25 (C) and 35% (D) Azolla. Concentrates were formulated to be isoenergetic and isonitrogenous.
