Última Protein enrichment of Opuntia ficus-indica using Kluyveromyces marxianus in solid-state fermentation Ciencia e Investigación Agraria Herrera,Esperanza; Murillo,Manuel; Berumen,Leslie; Soto-Cruz,Nicolas O.; Páez-Lerma,Jesús B.. Abstract Opuntia ficus-indica is used in animal feed but has a low protein content (above 4%) in comparison to high-quality forage (above 16%). It is necessary to develop technologies that improve the nutrimental value of Opuntia ficus-indica through the process of solid-state fermentation (SSF). Therefore, the objective of this study was to evaluate the changes in the chemical composition of Opuntia ficus-indica during the SSF with the yeast Kluyveromyces marxianus ITD00262. Kluyveromyces marxianus ITD00262 was grown in glucose, peptone, yeast (GPY) broth, at 28 °C and pH 4.8 for 12 h. Opuntia ficusindica was incubated in SSF at 28 °C without inoculation (T1) or inoculated with K. marxianus ITD00262 (T2). Fermented samples of Opuntia ficus-indica were...

The objective of this study was to determine and compare seasonally the chemical composition, in vitro gas production, in situ degradability and ruminal fermentation of the diet selected by cattle grazing on native rangeland over two years. Diet samples were collected from four esophageal fistulated steers (350 ± 3 kg BW), and four ruminally fistulated steers (342 ± 1.5 kg BW) were used to evaluate degradation and ruminal fermentation. Data were analyzed using a repeated measurements design. The crude protein (CP), in vitro dry matter digestibility (IVDMD) and metabolizable energy (ME) were higher in 2008 (P≤0.01) and in the summer (P≤0.05). The volatile fatty acids (VFA) and propionate concentrations were affected by season and year...
