VALORIZATION OF AGRI-FOOD BY-PRODUCTS TO PRODUCE HIGH ANIMAL PROTEIN QUALITY, ARTEMIA BIOMASS AT LAB SCALE

El desarrollo humano en cualquier modelo de sociedades ha generado variados tipos de sub-productos que pueden ser utilizables en el marco de la economía circular. Un grupo de ellos son originados en grandes cantidades por la actividad agroindustrial. En el marco del presente estudio, se trabajó con plumas de la crianza de pollos, orujo de vino, harinilla de cáscara de trigo y de cáscara de arroz. En este contexto, se planteó evaluar la producción de biomasa de Artemia, alimentadas con estos subproductos agroindustriales. Primero, se deshidrataron hasta alcanzar 10% de humedad y luego micronizaron. Se propuso un diseño cuasi-experimental simple completamente al azar. Se trabajaron cuatro tratamientos con tres réplicas cada uno. Se colocaron diez mil nauplios en botellas con un litro de agua de mar filtrada y con aire permanente. Se preparó una suspensión con cada monodieta (50 g/L) y se suministró manteniendo 15 cm de turbiedad en cada unidad. En general, ambas monodietas de plumas obtuvieron los mejores aumentos de biomasa, tasa de crecimiento específico, supervivencia y conversión alimenticia; y en específico la monodieta de plumas hidrolizada con diferencias significativas. En consecuencia, se concluye, que los sub-productos de la agro-industria pueden ser convertidos en proteínas animales de alta calidad, de fácil digestibilidad, mediante la producción de biomasa de Artemia.

  • Abstract: Human being developing in all society models has generated a variety of by- products that can still be useful into circularity framework. Agro-industrial activity produces huge volumes of by-products. In this regard, poultry feather, grape pomace, rice husk and wheat middling are good examples. For this reason, they were tested as monodiet on Artemia biomass production. They were grinded, dehydrated up to 10% wet and then micronized (38 microns). In case of feather, it was prepared as hydrolysed and non-hydrolysed way. A simple quasi-experimental design completely randomized was proposed. Four treatments with three replicates were performed. Ten thousand hatched nauplii were seeded into one liter bottle with filtered seawater aerated constantly. Feeding suspension (50 g/L) were prepared with each monodiet. Artemia was fed on keeping 15 cm of turbidity in each unit. Best biomass increase production, specific grow rate, survival and feed conversion rate were obtained in general by poultry feather and in specific by hydrolysed feather with significant differences. As a consequence, it can be concluded, that agri-food by-product specially poultry feather can be converted in high animal protein quality with easy digestibility through Artemia biomass production.
