Resumen

RAMOS-JUAREZ, Jesús Alberto et al. Effect of the urea level of sacchapulido on the degradation of elephant grass (Pennisetum purpureum). Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.15, pp.563-571. ISSN 2007-901X.  http://dx.doi.org/10.19136/era.a5n15.1560.

The effect of the urea level of the fermented supplement Sacchapulido (SP) on the degradation of elephant grass (Pennisetum purpureum) was evaluated. The pH, N-NH3 and in situ and effective degradation (ID and ED respectively) were determined, as well as the kinetic parameters of dry matter (DM), NDF and ADF of the forage. Five fistulated bovines were used in a 5 x 5 Latin square design. The standard deviation indicated that the supplements have between 0.5 and 1.0% urea; they contributed 10% more biomass due to the increase in size of the potentially degradable fraction of the feed, both in the NDF and cellular content. Due to the cost of urea, the use of SP with 0.5% urea is recommended.
