Effects in Poultry and Swine


Nutrafito (Quillaja saponaria) and Nutrafito Plus (Mixture of Quillaja saponaria & Yucca schidigera), improve intestinal health, nutrient absorption and intestinal integrity. Several studies have been developed in broilers either, in controlled conditions and at commercial scale, in the United States, Southern Poultry Research – Athens, GA (2012), Texas A & M University (2005), Mississippi State University (2005), Mexico (2003), Brazil (2002), others (2012-2018), demonstrating that oral supplementation of Nutrafito Plus improves growth and feed efficiency (FCR), similar to that achieved with antibiotic (AGP) and non-antibiotic growth promoters (probiotics, prebiotics, etc).

On the other hand, Quillaja (Nutrafito) and Quillaja & Yucca blend (Nutrafito Plus), can be added to bird diets, to modulate the innate and adaptive immune response, increase resistance against pathogens, particularly Salmonella in chickens (Toro et al, 2001), and improve the efficiency of broiler vaccine programs like Newcastle (Araujo et al, 2013 – USP-DNP- Brazil).



In pigs, the oral administration of Nutrafito and Nutrafito Plus, improves the productive performance and the immune status (IgA, IgG, Interferon gamma) of pigs at day 20 post weaning (Ilsley et al, 2005; Václavková et al, 2008; P. Assavacheep, et al, 2015 – Chulalongkorn University, Thailand). In pregnant sows, the oral addition of Nutrafito Plus, improves the colostrum IgA at farrowing, the body weight of newborn piglets (Ilsley et al, 2005), and reduces the stillbirths.

Effects in Aqua

Dietary supplementation with Quillaja saponin product at low levels improve metabolic efficiency (energy retention, conversion of lipids and fat in the carcass) of Tilapia (Oreochromis niloticus) and Carp (Cyprinus carpio) and has immunopotentiator effects in Yellowtail (Seriola quinqueradiata) leucocytes. Equally, the oral administration of a “Quillaja δ Yucca” blend (Nutrafito Plus), improve the immunoresponse and performance (weight gain and feed conversion ratio FCR) of  Shrimp (Litopenaeus vannamei) and Catfish (Pangasius hypophthalmus).

Ammonia Reduction

Nutrafito and Nutrafito Plus, can be used as additives in animal nutrition for ammonia reduction in pigs, chickens, pets, and fish. At low levels Nutrafito and Nutrafito Plus reduce the environmental ammonia in 30-50%. The synergy between Saponins and Glycocomponents fraction naturally present in extracts from Quillaja δ Yucca plays a fundamental role in controlling ammonia.

Today we have formed a strategic alliance with Phibro.
