ESPAÑA ES, DESPUES DE ITALIA, EL SEGUNDO MAYOR PRODUCTOR HORTOFRUTICOLA EUROPEO Y EL PRIMER EXPORTADOR DE ESTOS PRODUCTOS. ESTA SITUACION CONVIERTE AL SECTOR DE LAS FRUTAS Y HORTALIZAS EN EL MAS IMPORTANTE EN EL CONJUNTO DEL SECTOR AGRARIO DE NUESTRO PAIS, CON UNA IMPORTANTE ACTIVIDAD EMPRESARIAL QUE GENERA UNA GRAN CANTIDAD DE DESECHOS VEGETALES, MUCHOS DE LOS CUALES TIENEN UN CONSIDERABLE CONTENIDO EN NUTRIENTES, PERO TAMBIEN PRESENTAN UN ELEVADO POTENCIAL CONTAMINANTE. DEBIDO A ELLO, LAS EMPRESAS DEL SECTOR ESTAN HACIENDO UN ESFUERZO IMPORTANTE POR BUSCAR VIAS DE UTILIZACION DE ESTOS RESIDUOS, SIENDO SU USO EN ALIMENTACION ANIMAL UNA DE LAS MAS PROMETEDORAS. POR OTRA PARTE, EL ENCARECIMIENTO DE LAS MATERIAS PRIMAS PARA ALIMENTACION ANIMAL REGISTRADO EN LOS ULTIMOS AÑOS HA AFECTADO NEGATIVAMENTE AL SECTOR GANADERO Y HA INCREMENTADO LA NECESIDAD DE ENCONTRAR MATERIAS PRIMAS ALTERNATIVAS PARA FORMULAR LOS PIENSOS. LA UTILIZACION DE CUALQUIER RECURSO EN LA ALIMENTACION ANIMAL REQUIERE CONOCER SU VALOR NUTRITIVO, PERO ESTA VALORACION ES COMPLEJA EN EL CASO DE LOS SUBPRODUCTOS AGROINDUSTRIALES DEBIDO A SU COMPOSICION HETEROGENEA Y VARIABLE, Y CON FRECUENCIA DESEQUILIBRADA. ESTAS DIFICULTADES HAN CONTRIBUIDO A QUE EXISTAN POCOS DATOS SOBRE EL VALOR NUTRITIVO DE ESTOS SUBPRODUCTOS, ESPECIALMENTE DE LOS GENERADOS EN NUESTRO PAIS. EN ESTE PROYECTO SE PLANTEA ANALIZAR LA VARIABILIDAD EXISTENTE EN LA COMPOSICION QUIMICA DE ALGUNOS SUBPRODUCTOS AGROINDUSTRIALES (ORUJO GRASO DE ACEITUNA, PULPA DE CITRICOS, PULPA DE TOMATE Y RESTOS DE LA INDUSTRIA CONSERVERA DE BROCOLI Y COLIFLOR), ESTIMAR SU VALOR NUTRITIVO PARA LOS PEQUEÑOS RUMIANTES (OVINO Y CAPRINO) Y ANALIZAR SU INFLUENCIA EN LA CALIDAD DE LOS PRODUCTOS OBTENIDOS (CARNE Y LECHE). PARA LOGRAR ESTE OBJETIVO SE REALIZARAN ESTUDIOS DE FERMENTACION IN VITRO, ENSAYOS CON FERMENTADORES, PRUEBAS IN VIVO DE DIGESTIBILIDAD Y BALANCE DE NUTRIENTES, Y PRUEBAS DE RENDIMIENTO PRODUCTIVO CON CORDEROS DE CEBO Y CON OVEJAS Y CABRAS EN LACTACION. DEBIDO A QUE LOS SUBPRODUCTOS SELECCIONADOS CONTIENEN COMPUESTOS BIOACTIVOS (CAROTENOIDES, POLIFENOLES, ..), SU INCLUSION EN LA DIETA PODRIA TENER EFECTOS BENEFICIOSOS SOBRE LA CALIDAD DE LOS PRODUCTOS Y EL ESTADO SANITARIO DE LOS ANIMALES, POR LO QUE ESTOS ASPECTOS TAMBIEN SE INVESTIGARAN EN EL PROYECTO. ADICIONALMENTE, SE PRETENDE ANALIZAR SU POSIBLE INFLUENCIA EN LAS POBLACIONES MICROBIANAS RUMINALES, LAS EMISIONES DE METANO Y LA UTILIZACION DE NITROGENO, YA QUE ESTUDIOS PREVIOS INDICAN QUE ALGUNOS DE ESTOS SUBPRODUCTOS PUEDEN TENER UN EFECTO MODULADOR DE LA FERMENTACION RUMINAL Y REDUCTOR DE LAS EMISIONES DE METANO. EL OBJETIVO FINAL DEL PROYECTO ES GENERAR INFORMACION PRACTICA QUE FACILITE EL USO DE ESTOS SUBPRODUCTOS AGROINDUSTRIALES EN LA ALIMENTACION DE LOS PEQUEÑOS RUMIANTES, LO QUE BENEFICIARIA AL SECTOR GANADERO Y A LAS EMPRESAS AGROALIMENTARIAS QUE LOS GENERAN Y CONTRIBUIRIA A MITIGAR LA CONTAMINACION MEDIOAMBIENTAL. ADICIONALMENTE, EL PROYECTO GENERARA INFORMACION CIENTIFICA SOBRE LA UTILIZACION DIGESTIVA DE ESTAS MATERIAS PRIMAS ALTERNATIVAS POR LOS PEQUEÑOS RUMIANTES. (Spanish)

SPAIN IS, AFTER ITALY, THE SECOND LARGEST EUROPEAN FRUIT AND VEGETABLE PRODUCER AND THE FIRST EXPORTER OF THESE PRODUCTS. THIS SITUATION MAKES THE FRUIT AND VEGETABLES SECTOR THE MOST IMPORTANT IN THE WHOLE AGRICULTURAL SECTOR OF OUR COUNTRY, WITH AN IMPORTANT BUSINESS ACTIVITY THAT GENERATES A LARGE AMOUNT OF VEGETABLE WASTE, MANY OF WHICH HAVE A CONSIDERABLE NUTRIENT CONTENT, BUT ALSO HAVE A HIGH POLLUTING POTENTIAL. BECAUSE OF THIS, COMPANIES IN THE SECTOR ARE MAKING AN IMPORTANT EFFORT TO SEARCH FOR WAYS OF USING THESE WASTES, WITH ITS USE IN ANIMAL FEED BEING ONE OF THE MOST PROMISING. ON THE OTHER HAND, THE INCREASE IN RAW MATERIALS FOR ANIMAL FEED RECORDED OVER THE LAST FEW YEARS HAS NEGATIVELY AFFECTED THE LIVESTOCK SECTOR AND INCREASED THE NEED TO FIND ALTERNATIVE RAW MATERIALS FOR THE FORMULATION OF FEED. THE USE OF ANY RESOURCE IN ANIMAL FEED REQUIRES KNOWING ITS NUTRITIONAL VALUE, BUT THIS VALUATION IS COMPLEX IN THE CASE OF AGRO-INDUSTRIAL BY-PRODUCTS DUE TO THEIR HETEROGENEOUS AND VARIABLE COMPOSITION, AND OFTEN UNBALANCED. THESE DIFFICULTIES HAVE CONTRIBUTED TO THE FACT THAT THERE IS LITTLE DATA ON THE NUTRITIONAL VALUE OF THESE BY-PRODUCTS, ESPECIALLY THOSE GENERATED IN OUR COUNTRY. THIS PROJECT AIMS TO ANALYSE THE VARIABILITY IN THE CHEMICAL COMPOSITION OF SOME AGRO-INDUSTRIAL BY-PRODUCTS (OIL FAT, CITRICO PULP, TOMATO PULP AND REMAINS OF THE BROCOLI AND CAULIFLOWER CANNING INDUSTRY), TO ESTIMATE THEIR NUTRITIONAL VALUE FOR SMALL RUMINANTS (OVINE AND CAPRINE) AND TO ANALYSE THEIR INFLUENCE ON THE QUALITY OF THE PRODUCTS OBTAINED (MEAT AND MILK). TO ACHIEVE THIS OBJECTIVE, IN VITRO FERMENTATION STUDIES, FERMENTATION TESTS, IN VIVO TESTS OF DIGESTIBILITY AND NUTRIENT BALANCE, AND PRODUCTIVE PERFORMANCE TESTS WITH BAIT LAMBS AND SHEEP AND GOATS IN LACTATION WILL BE CARRIED OUT. BECAUSE THE SELECTED BY-PRODUCTS CONTAIN BIOACTIVE COMPOUNDS (CAROTENOIDS, POLYPHENOLS,..), THEIR INCLUSION IN THE DIET COULD HAVE BENEFICIAL EFFECTS ON THE QUALITY OF THE PRODUCTS AND THE HEALTH STATUS OF ANIMALS, SO THESE ASPECTS WERE ALSO INVESTIGATED IN THE PROJECT. IN ADDITION, THE AIM IS TO ANALYSE THEIR POSSIBLE INFLUENCE ON RUMINAL MICROBIAL POPULATIONS, METHANE EMISSIONS AND THE USE OF NITROGEN, SINCE PREVIOUS STUDIES INDICATE THAT SOME OF THESE BY-PRODUCTS MAY HAVE A MODULATING EFFECT OF RUMINAL FERMENTATION AND REDUCING METHANE EMISSIONS. THE FINAL OBJECTIVE OF THE PROJECT IS TO GENERATE PRACTICAL INFORMATION THAT FACILITATES THE USE OF THESE AGRO-INDUSTRIAL BY-PRODUCTS IN THE FEEDING OF SMALL RUMINANTS, WHICH BENEFITS THE LIVESTOCK SECTOR AND THE AGRI-FOOD COMPANIES THAT GENERATE THEM AND WILL CONTRIBUTE TO MITIGATING ENVIRONMENTAL POLLUTION. IN ADDITION, THE PROJECT WILL GENERATE SCIENTIFIC INFORMATION ON THE DIGESTIVE USE OF THESE ALTERNATIVE RAW MATERIALS BY SMALL RUMINANTS. (English)
