FERRARI JUNIOR, E.; PAULINO, V.T.; POSSENTI, R.A.  and  LUCENAS, T.L.. Additives in silage of paraisograss (pennisetum hybridum cv. paraiso). Arch. zootec. [online]. 2009, vol.58, n.222, pp.185-194. ISSN 1885-4494.

This experiment was conducted at Instituto de Zootecnia, Nova Odessa, Brazil, in order to evaluate the silage Pennisetum hybridum cv. Paraisograss, with 100 days old. The treatments of the ensiled grass studied were: 1) Pennisetum hybridum cv. Paraíso (PG) without additive, 2) PG + 5% of citric pulp, 3) PG + with 10 % of citric pulp, 4) PG + with 1% of calcium oxide and 5) PG + commercial additive (Silomax). The experimental design employed was randomised blocks (5 treatments vs. 4 replications). DM, CP, IVDM digestibility and lactic acid contents increased with citric pulp addition. NDF and ADF decreased for this same additive. Calcium oxide addition did not affect the fermentative characteristics of silage. The commercial additive controlled the non desirable fermentation and approving the desirable one. Exception the treatment with calcium oxide, the other treatments showed nutrititional and fermentative characterists adequate of ensiling process to Pennisetum hybridum cv. Paraíso.
