Natu-B4™ is not just a total replacement for choline chloride, it is an alternative that exceeds expectations terms of performance, energy efficiency and sustainability.
With over 20 years of application and an extensive list of scientific publications, Natu-B4™ is the choice of producers looking to maximize results without compromising animal health or the environment.
Better performance: By stimulating metabolic pathways, Natu-B4™ increases lipid utilization and gluconeogenesis, thereby increasing the amount of metabolizable energy available for animal performance and health, as reflected in GPD, CI, reproductive parameters, etc.
Reduce fat deposition: By increasing lipid utilization, Natu-B4™ can be applied in a specific protocol to reduce fat deposition in the liver and abdominal cavity of poultry and in the subcutaneous tissue of pigs, avoiding chronic problems resulting from excessive deposition, and potentially improving profitability at the slaughterhouse.
More results: By excluding choline chloride, we reduce the intake of chlorine in diets, which reduces the likelihood of metabolic problems resulting from its excess.
Historical differences in weight gain and feed conversion rate between broilers supplemented with Natu-B4™ and choline chloride:


If applied in a specific protocol, Natu-B4™ can significantly modulate the carcass composition of poultry and pigs.
> Thus, less fat is deposited and more energy is available for muscle development.
Poultry: less fat deposition in the liver and abdomen, lower incidence of fatty liver and more energy available for muscle development.




Pigs: Lower subcutaneous fat deposition which means leaner carcasses, greater energy availability for muscle development and higher percentage of meat in carcasses with higher yield of cuts.



Natu-B4™ reduces fat deposition in the carcass by converting it into energy for muscle growth and development.
The amount of metabolizable energy available is known and this value can save energy in the formulation of poultry diets, significantly reducing their cost.
Since Natu-B4™ acts in certain metabolic pathways, i.e. after nutrient absorption, it does not compete for substrates with enzymes and emulsifiers, and may even have a complementary or synergistic effect with these additives.
If you use bicarbonate to balance sodium with a lower chlorine content, by using Natu-B4™ you can reduce its inclusion, increasing common salt and thus reducing costs.
In addition, the inclusion of Natu-B4™ is in itself more economical than that of choline chloride. This is due to its high potency, which comes from the synergy between several phytoactives, resulting in low inclusion doses. Each kg of Natu-B4™ is equivalent to 4.84 kg of 60% choline chloride.
For every ton of Natu-B4™ applied, we stop using almost 5 tons of petroleum derivatives from a chemical industry. Instead, we use a 100% natural product derived from carbon-fixing plants.
