Ruminal degradability and in vitro intestinal digestibility of sunflower meal and in vitro digestibility of olive by-products supplemented with urea or sunflower meal

By‐products from viticulture and the wine industry: potential as sources of nutrients for ruminants

“…Wine lees showed higher in vitro digestibility than sunflower meal, which reached values of 0.68 for OM 43 and 0.54 for DM. 35 However, in vitro digestibility for lees was lower than that for legume seeds (from 0.89 to 0.97 and 0.98 for DM and CP respectively; Molina-Alcaide E et al, unpublished results). PEG increased the in vitro digestibility of CP of VS and GMG, which may indicate, in agreement with other observations, 16,44 that tannins present in these by-products limit protein availability.…”

“…In relation to cell wall content, the lignocellulosic vine and winery by-products are comparable to those from other origins (olive and straw), indicating similar energy potential. The wine lees could be sources of protein for ruminants, although CP was lower than in other feeds frequently used as protein sources, such as sunflower meal 35 or legume seeds. The gross energy content of winery by-products, with the exception of lees, was similar to that of olive by-products.…”

Protein increase and lysine production by a Paecilomyces variotii strain grown on two-phase olive mill waste

“…Two-phase olive mill waste has already been proposed as livestock feed (Molina Alcaide and Nefzaoui 1996), but due to its low concentration of proteins, especially lysine, it is recommended to use protein supplements (Molina Alcaide et al 2003). The fermented product of the SSF experiments with the specific Paecilomyces variotii isolate had a higher concentration of proteins and an aminoacid profile that meets the needs of FAO for animal feed.…”

“…Haddadin et al (1999) have focused on the production of microbial protein after fermentation of waste pomace from the press system with various fungal strains. Molina Alcaide et al (2003) have mentioned the role of lysine in the final product. Lysine, as an essential aminoacid, cannot be synthesized by animals and has to be included in their feed.…”

Caracterización y uso de compost de alperujo como enmienda orgánica. Evaluación agronómica y medioambiental

“…En este ámbito, sus propiedades nutritivas pueden incrementarse utilizando el método de fermentación en estado sólido, desarrollado por microorganismos sobre un soporte sólido, que se ha utilizado con éxito en la producción de enzimas y componentes de alimentos para animales (Molina Alcaide et al, 2003).…”
