The general concern about residues, the meat quality and the possibility of cross resistance with some products used in human antibiotic therapy, has led to regulate the use of antibiotic in animal nutrition as prophylactics and as growth promoters, with an apparent tendency to its future total prohibition.

PROBENA does not offer alternatives to antibiotics…. PROBENA offers natural products to promote the health and immune status of the animals. Having healthy animals it is easier to abandon antibiotics, reducing the time production and getting better the quality of the final product.

Biocitro composition allows animals to improve their intake and feed efficiency. Subsequently animals get a better development of its natural immunity and quality production (meat, eggs, milk…) acting always in harmony with nature.


The product is a stable biomass extract of four types of citrus organic fruits:


(Citrus paradisi)


(Citrus reticulata blanco)


(Citrus aurantium L. subespecie bergamia)

Sweet Orange
