Abstract

An experiment was developed to determine the effect of addition of the marine alga Lithothamnium calcareum in the apparent digestibility of a low quality forage. Twelve adult lambs were kept in metabolical individual cages using a randomly design with three replications and four treatments as follows: I - Brachiaria decumbens grass hay, processed after the seed harvest; II - Hay plus 1000 ppm of calcium from CaCO3 (p.a.); III - Hay plus 1000 ppm of calcium from mineral supplement of alga; IV - Hay plus 2000 ppm of calcium from mineral supplement of alga. The mineral supplement of alga increased the digestibility of crude protein in 7,5% with dosage 1000 ppm and in 12% with dosage of 2000 ppm, when compared with control treatment, but such changes were not significant (P < 0,05). No differences were observed for dry matter and crude fiber.
