          Abstract

          Abstract In order to evaluate the chemical characteristics of taro tuber silage (Colocasia esculenta L. Schott) with panela cane (POJ93) and its effect on productive indicators of gestating commercial sows, a total of 30 F1 Landrace x Duroc sows with an average weight of 218.87 ± 2.85 kg were used. They were divided into two treatments (0 and 50% inclusion of silage in the diet), in equal parts, according to a completely randomized design. In the silage samples, the pH, dry matter, crude protein, crude fiber, ash, ether extract, nitrogen-free extracts and gross energy were determined. In the productive performance, the final weight of the sows, piglets born at birth, piglets born alive at birth, litter weight, piglet weight at born, food intake and the feeding cost per sow were evaluated. Data were processed by ANOVA and contrast of means with Fisher's test (P <0.05). The pH was stabilized between days four (4.15) and thirty (4.15). The silage showed good content of dry matter (70.99 %), crude protein (7.01 %), ash (13.16 %), nitrogen-free extract (72.42 %), gross energy (895.21 kJ/kg DM) and low content of ether extract (1.31 %) and crude fiber (6.13 %). There were no significant differences (P ˃ 0.05) between treatments for the final weight of the sows, piglets born at birth, total live born piglets, litter weight, piglet weight at born and food intake. The sows that were fed silage showed the lowest (P <0.05) feeding cost per sow. Under the Ecuadorian Amazon conditions, the inclusion of 50 % taro tubers silage (Colocasia esculenta L. Schott) with panela cane (POJ93) in the diet for gestating commercial sows did not affect the productive performance and reduced the cost production on the stage, so it constitutes an alternative food source with optimal nutritional characteristics for this category.

          Resumen Para evaluar las características químicas de un ensilado de tubérculos de taro (Colocasia esculenta L. Schott) con caña panelera (POJ93) y su efecto en indicadores productivos de cerdas comerciales en gestación, se utilizaron 30 cerdas F1 Landrace x Duroc, con peso promedio de 218.87 ± 2.85 kg. Se dividieron en dos tratamientos (0 y 50 % de inclusión de ensilado en la dieta), en partes iguales, de acuerdo con un diseño completamente aleatorizado. En las muestras de ensilado se determinó el pH, materia seca, proteína bruta, fibra bruta, cenizas, extracto etéreo, extractos libres de nitrógeno y energía bruta. En el desempeño productivo se evaluó el peso final de las cerdas, lechones nacidos al parto, lechones nacidos vivos al parto, peso de la camada, peso del lechón al nacimiento, consumo de alimento y el costo de alimentación por cerda. Los datos se procesaron por ANOVA y el contraste de medias con la prueba de Fisher (P < 0.05). El pH se estabilizó entre los días cuatro (4.15) y treinta (4.15). El ensilado presentó buen contenido de materia seca (70.99 %), proteína bruta (7.01%), cenizas (13.16 %), extracto libre de nitrógeno (72.42 %), energía bruta (895.21 kJ/kg MS) y bajos contenidos de extracto etéreo (1.31 %) y fibra bruta (6.13%). No hubo diferencias significativas (P ˃ 0.05) entre tratamientos para el peso final de las cerdas, lechones nacidos al parto, lechones nacidos vivos al parto, peso de la camada, peso del lechón al nacimiento y consumo de alimento. Las cerdas que se alimentaron con ensilado presentaron el menor (P < 0.05) costo de alimentación por cerda. En las condiciones de la Amazonía ecuatoriana, la inclusión de 50 % de ensilado de tubérculos de taro (Colocasia esculenta L. Schott) con caña panelera (POJ93) en la dieta destinada a cerdas comerciales en gestación no afectó el comportamiento productivo y redujo el costo de producción en la etapa, por lo que constituye una fuente de alimento alternativo de óptimas características nutricionales para esta categoría.

              Single Cell Protein—State-of-the-Art, Industrial Landscape and Patents 2001–2016

              By 2050, the world would need to produce 1,250 million tonnes of meat and dairy per year to meet global demand for animal-derived protein at current consumption levels. However, growing demand for protein will not be met sustainably by increasing meat and dairy production because of the low efficiency of converting feed to meat and dairy products. New solutions are needed. Single cell protein (SCP), i.e., protein produced in microbial and algal cells, is an option with potential. Much of the recent interest in SCP has focused on the valorisation of side streams by using microorganisms to improve their protein content, which can then be used in animal feed. There is also increased use of mixed populations, rather than pure strains in the production of SCP. In addition, the use of methane as a carbon source for SCP is reaching commercial scales and more protein-rich products are being derived from algae for both food and feed. The following review addresses the latest developments in SCP production from various organisms, giving an overview of commercial exploitation, a review of recent advances in the patent landscape (2001–2016) and a list of industrial players in the SCP field.
