“…In contrast, foods that do not contain these phenolic substances or where they are present at low levels, as in most oilseeds, help mitigate greenhouse gases and show more rapid degradation, which also contributes to the growth of ruminal microorganisms. However, despite these advantages, protein may be lost as ammonium when energy levels in the diet are insufficient (Pablo-Pérez et al, 2014;Oliveira et al, 2015).…”

Araújo. 2015. Potential in vitro degradability and gas production of the byproducts of the biodiesel chain. Cienc. Inv. Agr. 42(2):285-293. The objective of this research was to evaluate the in vitro degradability and gas production from different byproducts of the domestic biodiesel industry (Glycine max, Brassica napus L., Helianthus annuus and Raphanus sativus L.) using four increasing levels (0, 30, 50 and 70%) of replacement of Pennisetum purpureum. The inoculum for the in vitro incubations was obtained from three Holstein cows with rumen fistulas. Gas production was measured at 3, 6, 12, 24 and 48 hours of incubation. The experimental design was a completely randomized 4 × 4 factorial arrangement, with byproducts and their levels being the factors. The results showed a significant effect (P ≤ 0.05) of all byproducts. A higher level of degradation was observed following 48 hours of incubation with Glycine max compared with other byproducts, but it did not reduce gas production; Raphanus sativus was the most efficient byproduct to reduce the total gas production. The lowest degradation was obtained with sunflower. All the studied byproducts may be used in the diet of ruminants as potential protein supplements.

“…Estudios previos en el país demuestran que la proteína de la semilla de L. campestris y L. montanus presenta alta degradabilidad ruminal (Pablo-Pérez et al, 2014) y digestibilidad por lo que puede ser utilizada como complemento en la alimentación previa eliminación de alcaloides por medios físicos (Jiménez-Martínez et al, 2003a, 2003bGüemes-Vera et al, 2012). En los Valles de Serdán y Libres en el estado de Puebla, crecen al menos cinco especies de Lupinus en los ecosistemas forestales, incluidas L. campestris y L. montanus (Lagunes-Espinoza et al, 2012).…”

En el Eje Neovolcánico Transversal Mexicano abundan diversas especies del género Lupinus, cuyas semillas presentan altos contenidos proteicos que pudieran ser aprovechados en alimentación humana y animal. Plantas en floración y fructificación de Lupinus campestris, L. exaltatus, L. hintonii y L. montanus fueron recolectadas en los Valles de Serdán y Libres del estado de Puebla, México, durante mayo y agosto de 2011, entre 2486 y 3442 msnm, para análisis químico proximal, alcaloides totales (AT), polifenoles totales (PT) y taninos condensados (TC) en diversos órganos de la planta. Las semillas presentaron el mayor porcentaje de proteína cruda (PC) (32.5 a 43.5 g/100 g); de extracto etéreo (EE) (6.5 a 7.5 g/100 g), los menores de fibra detergente neutro (FDN) (16.7 a 24.7 g/100 g) y de fibra detergente ácido (FDA) (4.4 a 7.9 g/100 g), comparado con el de hoja + tallo (PC: 22.2 a 25.5 g/100 g; EE: 0.1 a 1.7 g/100 g; FDN: 38.2 a 44.1 g/100 g, FDA: 21.7 a 30.1 g/100 g), respectivamente. Los pericarpios (vainas sin semilla) presentaron un menor contenido de PC (10.9 a 22.8 g/ 100 g) y EE (0.1 a 0.6 g/100 g), pero mayor FDN (54.4 a 68.4 g/100 g) y FDA (34.0 a 47.1 g/100 g). Los AT en semilla fueron de 2.4 a 5.4 g/100 g (L. hintonii con el mayor contenido), los PT de 221 a 554 mg/100 g, y los TC de 0.0 a 22.7 mg kg-1 (L. exaltatus y L. campestris no presentaron taninos). En el follaje, los AT variaron de 1.2 a 3.3 g/100 g, PT de 556 a 813 mg/100 g y TC de 66.85 a 99.7 mg kg-1. La semilla y el follaje de las especies de Lupinus son fuente de proteína y polifenoles, y requerirán de la reducción del nivel de alcaloides vía procesos tecnológicos o mejoramiento genético para obtener variedades aptas para uso en alimentación.
