DELGADILLO RUIZ, Lucia et al. Nutrient profile evaluation of agave bagasse as alternative feedstuffs for ruminants. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe11, pp.2099-2103. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i11.778.

The aim of this project was to evaluate the in vitro nutrient profile of Agave salmiana (AS) and Agave weberi cela (AWC) bagasse as alternative feedstuffs for ruminant nutrition. The bagasse was collected in Jalpa, Zacatecas during 2010. From collected samples, dry matter (DM), ash, crude fiber (CF), ether extract (EE), crude protein (CP), total organic carbon (TOC), neutral detergent fiber (NDF), and total reducing sugars (TRS) were evaluated. Macro- and micro-minerals were determined by atomic absorption spectroscopy. Also, it was used an in vitro gas production technique to evaluate fermentation kinetic, and after 48h of incubation samples were used to quantified VFA production. Crude protein (%) (2.25 vs 2.73), EE (%) (0.274 vs 0.272), CF (%) (22.15 vs 16.58) and ash (%) (2.14 vs 1.81) were not different statistically (p> 0.05) between AS and AWC treatment. Values for NDF (% DM) were statistically different (p< 0.05) between AS (45.45) and AWC (52.95) treatments. No differences on VFA’s were observed among agave bagasse and bean straw. Calcium (%) values averaged 3.46 and 1.95 for AS and AWC-treatments, respectively. It is concluded that Agave bagasse can represents an alternative feedstuffs for ruminants, especially at dry season.
