UNO DE LOS PRINCIPALES DESAFIOS A LOS QUE SE ENFRENTA LA HUMANIDAD RESIDE EN ALIMENTAR A LOS 9000 MILLONES DE PERSONAS QUE SE ESTIMA HABITARAN EL PLANETA EN 2050, RETO QUE HA DE SER ASUMIDO CON LOS RECURSOS LIMITADOS DE LOS QUE DISPONE LA TIERRA. ESTA ES LA RAZON POR LA CUAL LAS ESTRATEGIAS EUROPEAS DE I + D + I (POR EJEMPLO, HORIZONTE 2020, ESTRATEGIA ESPAÑOLA DE CIENCIA Y TECNOLOGIA Y DE INNOVACION 2013-2020) ESTAN PROMOVIENDO LA BUSQUEDA DE SOLUCIONES PARA LOGRAR UNA EUROPA MAS EFICIENTE EN EL USO DE LOS RECURSOS. EN LO QUE SE REFIERE AL SECTOR GANADERO, ESTO SIGNIFICA QUE ES NECESARIO AUMENTAR LA EFICIENCIA CON LA QUE LOS ANIMALES UTILIZAN LOS ALIMENTOS REDUCIENDO LOS INDICES DE CONVERSION, ES DECIR, LA CANTIDAD DE ALIMENTO NECESARIA PARA PRODUCIR UNA UNIDAD DE PRODUCTO ANIMAL, AL MISMO TIEMPO QUE SE MINIMIZA EL IMPACTO MEDIOAMBIENTAL DE LA ACTIVIDAD GANADERA (EMISION DE GASES DE EFECTO INVERNADERO) Y SE CUMPLEN LOS REQUISITOS PARA LA PRODUCCION DE ALIMENTOS SANOS, SEGUROS Y ATENDIENDO A CRITERIOS DE BIENESTAR ANIMAL Y DE ACEPTACION SOCIAL. _x000D_ EN ESTE SENTIDO, Y EN LO QUE A PRODUCCION DE CARNE DE CORDERO SE REFIERE, SE HA DEMOSTRADO QUE PARA LOGRAR LA MISMA GANANCIA DIARIA DE PESO HAY DIFERENCIAS EN LA INGESTION DE MATERIA SECA (IMS) DE HASTA UN 15% ENTRE LOS ANIMALES MAS Y MENOS EFICIENTES. ESTO SIGNIFICA, POR EJEMPLO, QUE EN EL TRANSCURSO DE 50 DIAS DE PERIODO DE CEBO LOS ANIMALES MAS EFICIENTES CONSUMIRIAN APROXIMADAMENTE 7,5 KILOS DE PIENSO MENOS QUE LOS ANIMALES MENOS EFICIENTES PARA PRODUCIR LA MISMA CANTIDAD DE CARNE. SIN EMBARGO, SELECCIONAR ANIMALES CAPACES DE REDUCIR LA INGESTA DE ALIMENTO SIN COMPROMETER LA TASA DE CRECIMIENTO O LA CALIDAD DE LA CANAL REQUIERE UN MEJOR CONOCIMIENTO DE LAS RAZONES POR LAS QUE SE ESTABLECEN ESTAS DIFERENCIAS EN LA EFICIENCIA. EN ESTE CONTEXTO, EFFILAMB HA SIDO DISEÑADO PARA ACLARAR LOS FACTORES Y MECANISMOS QUE SUBYACEN BAJO ESTAS DIFERENCIAS EN LA EFICIENCIA DE PRODUCCION DESDE UN PUNTO DE VISTA HOLISTICO, Y TODO ELLO COMO PRIMER PASO PARA DISEÑAR ESTRATEGIAS DIRIGIDAS A MEJORAR LA EFICIENCIA DE LA ALIMENTACION. _x000D_ INICIALMENTE EFFILAMB TIENE PREVISTO CONFIRMAR EL EFECTO DEL NIVEL DE ALIMENTACION EN LA FASE DE LACTANCIA SOBRE LA EFICIENCIA DURANTE LOS PERIODOS DE CEBO Y REEMPLAZO EN CORDEROS DE RAZA MERINA. DE CONFIRMARSE ESTE EFECTO EN LAS FASES POST DESTETE DE CORDEROS DE RAZA MERINA, EFFILAMB CUANTIFICARA EL RESULTADO PARA POSTERIORMENTE TRATAR DE ACLARAR LOS MECANISMOS QUE INTERVIENEN EN EL PROCESO. CON ESTE PROPOSITO, EFFILAMB IDENTIFICARA PROTEINAS CON BAJO NIVEL DE EXPRESION CUANDO SE COMPAREN ANIMALES DIVERGENTES EN LO QUE EFICIENCIA SE REFIERE. EFFILAMB, ADEMAS, CONFRONTARA MEDIDAS TRADICIONALES DE EFICIENCIA (INDICE DE CONVERSION) CON ASPECTOS DE INMUNIDAD, MICROBIOLOGIA DEL TRACTO GASTROINTESTINAL O ESTADO OXIDATIVO DEL ANIMAL, TRATANDO ASI DE ACLARAR LOS MECANISMOS SUBYACENTES QUE CONTROLAN LA EFICIENCIA CON LA QUE LOS CORDEROS UTILIZAN LOS ALIMENTOS DURANTE LAS FASES DE ENGORDE Y DE REEMPLAZO. EFFILAMB TAMBIEN TRATARA DE ACLARAR SI ANIMALES CON DIFERENTE EFICIENCIA PRESENTAN CARACTERISTICAS DISTINTAS EN LO REFERENTE A LA CALIDAD DE CARNE. (Spanish)

ONE OF THE MAIN CHALLENGES FACING HUMANITY IS TO FEED THE 9 BILLION PEOPLE ESTIMATED TO INHABIT THE PLANET BY 2050, A CHALLENGE THAT HAS TO BE TAKEN UP WITH THE LIMITED RESOURCES AVAILABLE TO THE EARTH. THIS IS WHY EUROPEAN R & D & I STRATEGIES (E.G. HORIZON 2020, SPANISH SCIENCE AND TECHNOLOGY STRATEGY AND INNOVATION 2013-2020) ARE PROMOTING THE SEARCH FOR SOLUTIONS TO ACHIEVE A MORE RESOURCE-EFFICIENT EUROPE. AS REGARDS THE LIVESTOCK SECTOR, THIS MEANS THAT IT IS NECESSARY TO INCREASE THE EFFICIENCY WITH WHICH ANIMALS USE FOOD BY REDUCING CONVERSION RATES, I.E. THE AMOUNT OF FOOD NEEDED TO PRODUCE A UNIT OF ANIMAL PRODUCT, WHILE MINIMISING THE ENVIRONMENTAL IMPACT OF LIVESTOCK ACTIVITY (EMISSION OF GREENHOUSE GASES) AND MEETING THE REQUIREMENTS FOR THE PRODUCTION OF HEALTHY, SAFE AND ANIMAL WELFARE AND SOCIAL ACCEPTANCE CRITERIA. _x000D_ in this sitting, and in which the production of lamb meat is retrusted, it has been demossed that in order to achieve the same day of weight, there are differences in the secret MATERIA INGESTION (IMS) of 15 % between the most effective animals and the least. THIS MEANS, FOR EXAMPLE, THAT IN THE COURSE OF 50 DAYS OF BAITING THE MOST EFFICIENT ANIMALS WOULD CONSUME APPROXIMATELY 7.5 KILOS OF FEED LESS THAN THE LESS EFFICIENT ANIMALS TO PRODUCE THE SAME AMOUNT OF MEAT. HOWEVER, SELECTING ANIMALS CAPABLE OF REDUCING FOOD INTAKE WITHOUT COMPROMISING GROWTH RATE OR CARCASS QUALITY REQUIRES A BETTER UNDERSTANDING OF THE REASONS WHY THESE DIFFERENCES IN EFFICIENCY ARE ESTABLISHED. IN THIS CONTEXT, EFFILAMB HAS BEEN DESIGNED TO CLARIFY THE FACTORS AND MECHANISMS THAT UNDERLIE THESE DIFFERENCES IN PRODUCTION EFFICIENCY FROM A HOLISTIC POINT OF VIEW, AND ALL THIS AS A FIRST STEP IN DESIGNING STRATEGIES AIMED AT IMPROVING THE EFFICIENCY OF FOOD. _x000D_ initially EFFILAMB MUST PREVIEW CONFERENCE THE EFFECT OF THE FOOD LEVEL IN THE LACTANCE PHOSE ON DURING EFICIENCE OF CEBO PERIOD AND REPLACE IN MERINE RACE CORDERS. IF THIS EFFECT IS CONFIRMED IN THE POST-WEANING PHASES OF LAMBS OF THE MERINE BREED, EFFILAMB QUANTIFIES THE RESULT AND THEN TRIES TO CLARIFY THE MECHANISMS INVOLVED IN THE PROCESS. FOR THIS PURPOSE, EFFILAMB WILL IDENTIFY PROTEINS WITH LOW LEVEL OF EXPRESSION WHEN COMPARING ANIMALS THAT DIFFER IN EFFICIENCY. EFFILAMB, IN ADDITION, WILL CONFRONT TRADITIONAL EFFICIENCY MEASURES (CONVERSION INDEX) WITH ASPECTS OF IMMUNITY, MICROBIOLOGY OF THE GASTROINTESTINAL TRACT OR OXIDATIVE STATE OF THE ANIMAL, THUS TRYING TO CLARIFY THE UNDERLYING MECHANISMS THAT CONTROL THE EFFICIENCY WITH WHICH LAMBS USE FOOD DURING THE FATTENING AND REPLACEMENT PHASES. EFFILAMB WILL ALSO TRY TO CLARIFY WHETHER ANIMALS WITH DIFFERENT EFFICIENCY HAVE DIFFERENT CHARACTERISTICS IN TERMS OF MEAT QUALITY. (English)
