Item Effect of dietary high-oleic acid and conventional sunflower seeds and their refined oils on fatty acid composition of adipose tissue and meat in broiler chickens(Journal of Animal and Feed Science, 2006) Ortiz Vera, Luis Tomás; Alzueta Lusarreta, Carmen; Rebolé Garrigós, Almudena; Rodríguez Membibre, María Luisa; Arija Martín, Ignacio; Brenes Paya, AgustínThe influence of different dietary fat source on performance, tissue fatty acid composition (abdominal fat, thigh and breast muscles) and abdominal fat melting point was evaluated in femaJe broiler chickens. Birds were red diets containing 80 g/kg of added fat by the inclusion ofhigh-oJeic acid sunflower secd (HOASS) and conventionaJ sunflower seed (CSS), their respective refined oiJs (HOASO and CSO) and lard during three weeks (from 2\ to 42 d of agc). Feed efficiency was significantly impaired by the inclusion ofHOASS and CSS in diet when compared with HOASO, CSO and lard. The levcls of the majar fatty acids (palmitic, oleic and linoleic) in cach animal tissue reflectcd the fatty acid profilc of the dietary fat (r2 >0.83). The linear regression analysis between fatty acid content ami mclting point of abdominal fat gave the highest coefficient of determination for thc saturated fatty acid contcnt (r2=0.80). It is concluded that the seeds ofhigh-oleic acid and conventional varieties orsunflower might be used in poultry feeding in arder to increase, rcspectively, monounsaturated and polyunsaturatcd fatty acid contents in both abdominal adipose tissue and intramuscular fato The feeding ofboth types of seeds had similar effects to their respective refined oils on the unsaturated to saturatcd rally acid ratio ofthe chicken tissues and on the melting point of abdominal fato NevcrtheJess, thcy showed a ncgative influence on fat firmness when compared with the dietary inclusion of lard.Item Yields and chemical composition of different parts of the common vetch at flowering and at two seed filling stages(Spanish Journal of Agricultural Research, 2004) Rebolé Garrigós, Almudena; Alzueta Lusarreta, Carmen; Ortiz Vera, Luis Tomás; Barro de Neyra, Mª del Carmen; Rodríguez Membibre, María Luisa; Caballero, R.Rendimientos y composición química de los componentes morfológicos de veza común en dos estados de madurez de la semilla En leguminosas forrajeras anuales como la veza común (Vicia saliva L), en las que la legumbre representa una proporción considerable de la biomasa total, el momento óptimo de corte puede no ajustarse al modelo clásico de disminución del valor nutritivo después de la floración. En este trabajo se evaluó el efecto del momento de recolección de la veza común sobre el rendimiento de los principales constituyentes químicos en condiciones de secano típicas de la Meseta Castellana. Las plantas se cosecharon durante dos años consecutivos (1996-1997 y 1997-1998), en floración y en dos estados de madurez de la legumbre (materia seca de la semilla 280 y 380 g kg-', respectivamente). Los resultados mostraron que, al avanzar la madurez, la mayor calidad y cantidad de la legumbre contrarresta la disminución de la calidad de las partes vegetativas de la planta. Los rendimientos de proteína bruta no se vieron afectados por un retraso en la fecha de recolección. Los de almidón, sin embargo, fueron mayores al estado de legumbre madura, y los de azúcares aumentaron desde la floración al estado de legumbre en el primer año, mientras que disminuyeron en el segundo año. Los rendimientos de constituyentes estructurales (fibra neutro-detergente, fibra ácido-detergente y celulosa ácido-detergente) siguieron una tendencia similar a los de la proteína bruta. Se concluye que existe un margen de maniobra entre la floración y las primeras fases de formación de la semilla (semilla con 380 g de materia seca kg-') que permite elegir las mejores condiciones de henificación.// In annual forage legumes such as the common vetch (Vicia saliva L), in which the pods represent a substantial proportion of the total biomass, the optimum harvesting stage mar not adjust to the classical model of decreasing nutritive value after flowering. The effect of harvest time on the yield of the main chemical components of common vetch was evaluated under field conditions typical ofthe Castilian Plain (Mediterranean continental-type climate under rain-fed conditions). Over two growing seasons (1996-1997 and 1997-1998), plants were harvested at flowering and at two stages during seed filling (characterized by a progressively higher dry matter content ofthe seed; 280 and 380 g kg-' respectively). The results show that the greater quality and quantity of the pods offsets the decrease in quality occasioned by the aging of the vegetative plant parts (stems plus leaves). Crude protein yields were not affected by delaying the harvest-time. Starch yields were higher when the plant was harvested during seed-filling. Sugar yields increased between flowering and seed filling in the first growing season but decreased in the second. Yields of structural components such as neutral-detergent fibre, acid-detergent fibre and acid-detergent cellulose, followed a pattern similar to that of crude protein. There therefore appears to be a flexible harvest period ranging from flowering until the beginning of seed filling (seeds with 380 g dry matter kg-'), which may be advantageous when trying to select optimum haymaking conditions.Item Bacterias productoras de ácido láctico : Efectos sobre el crecimiento y la flora intestinal de pollos, gazapos y lechones(2002) Rodríguez Membibre, María Luisa; Tortuero Cosialls, FranciscoLas bacterias productoras de ácido láctico incrementan la flora beneficiosa, previenen la colonización por agentes patógenos e influyen positivamente sobre el crecimiento y el aprovechamiento de los nutrientes. Con el fin de determinar los efectos de la administración oral de bacterias ácido lácticas sobre el crecimiento y la flora intestinal de animales jóvenes, se han llevado a cabo 14 experimentos en pollos, gazapos y lechones. Las bacterias ácido lácticas utilizadas han sido el lactobacillus casei, l. Acidophilus, streptococcus faecium c68 y cl15 y una mezcla de str. Faecium+l. Helveticus+l. Casei+l. Acidophilus que fueron administrados diariamente y de forma directa bien en agua o en leche o añadidos al pienso. Es posible afirmar que determinadas cepas de bacterias ácido lácticas mejoran el crecimiento de los gazapos y lechones y tanto en estas especies animales como en los pollos la administración de estos microorganismos aumentan la eficiencia nutritiva del pienso. A nivel intestinal originan un incremento de la relación bacterias ácido lácticas/coliformes que contribuye a establecer el equilibrio microbiano deseado, lo que conlleva a un mejor rendimiento animalItem Dietary inulin supplementation modifies significantly the liver transcriptomic profile of broiler chickens(Plos One, 2014) Sevane Fernández, Natalia; Bialade, Federica; Velasco Villar, Susana; Rebolé Garrigós, Almudena; Rodríguez Membibre, María Luisa; Ortiz Vera, Luis Tomás; Cañón Ferreras, Francisco Javier; Dunner Boxberger, Helene Susana; te Pas Marinus FWInclusion of prebiotics in the diet is known to be advantageous, with positive influences both on health and growth. The current study investigated the differences in the hepatic transcriptome profiles between chickens supplemented with inulin (a storage carbohydrate found in many plants) and controls. Liver is a major metabolic organ and has been previously reported to be involved in the modification of the lipid metabolism in chickens fed with inulin. A nutrigenomic approach through the analysis of liver RNA hybridized to the Affymetrix GeneChip Chicken Genome Array identified 148 differentially expressed genes among both groups: 104 up-regulated (≥1.4-fold) and 44 down-regulated (≤0.6-fold). Quantitative real-time PCR analysis validated the microarray expression results for five out of seven genes tested. The functional annotation analyses revealed a number of genes, processes and pathways with putative involvement in chicken growth and performance, while reinforcing the immune status of animals, and fostering the production of long chain fatty acids in broilers supplemented with 5 g of inulin kg−1 diet. As far as we are aware, this is the first report of a microarray based gene expression study on the effect of dietary inulin supplementation, supporting further research on the use of this prebiotic on chicken diets as a useful alternative to antibiotics for improving performance and general immunity in poultry farming, along with a healthier meat lipid profile.Item Effect of carob (Ceratonia siliqua L.) seed in broiler chick diets on nutrient digestibility and intestinal viscosity.(Recent advances of research in antinutritional factors in legume seeds and oilseeds, 2004) Ortiz Vera, Luis Tomás; Rodríguez Membibre, María Luisa; Alzueta Lusarreta, Carmen; Rebolé Garrigós, Almudena; Centeno, C.; Treviño Muñoz, Jesús; Muzquiz, M.; Hill, G.D.; Burbano, C.; Cuadrado, C.; Pedrosa, M.M.La inclusión de garrofín a niveles de 60 (ración CS-60) y 90 g/kg (ración CS-90) en una ración referencia produjo una marcada (P
