P.U.F.A.

Passing the rumen barrier

Targeted, controlled release
Microencapsulation technology allows substances to pass the rumen barrier and become active only in the sections of the tract responsible for absorption.

Enhanced stability and bioactivity
Microencapsulation ensures a stronger action of the active ingredient along the entire intestinal tract, increasing its bioavailability and maximising its effectiveness.
Our solutions
OLISTAT™ G
OLISTAT™ G combines allicin and cinnamaldehyde - two active ingredients with proven antimicrobial and antiprotozoal activity - in a microencapsulated formulation that ensures targeted intestinal release, where their action is most effective. The product balances the microbiota, supports the animal’s resistance to pathogens, and optimizes production performance throughout the entire rearing cycle.
Benefits
- Supports antiprotozoal and antimicrobial action, counteracting the proliferation and growth of intestinal pathogens
- Improves feed intake, optimizing nutrient conversion
- Supports weight gain and improves milk production
- Reduces the formation of methane and ammonia nitrogen, contributing to the farm’s environmental sustainability
SIL SEL 1% RBP
Selenium is an essential mineral for cattle health and performance, but its bioavailability is often compromised by physiological and environmental factors that limit absorption. SIL SEL 1% RBP ensures a consistent and balanced supply of selenium thanks to a microencapsulated formulation that guarantees controlled release and stable concentrations in both milk and blood. The product supports udder health, helps prevent mastitis, and reduces somatic cell count, with direct benefits for milk quality and animal fertility.
Benefits
- Ensures constant and balanced selenium levels in milk and blood over time
- Improves udder health, helping to prevent mastitis and reduce somatic cell count
- Supports fertility and post-partum recovery
- Improves production performance in beef and dairy cattle
CLASIX®
CLASIX® is a protected source of CLA - conjugated linoleic acid - a fatty acid important for lipid metabolism and the quality of animal products. In dairy cows, it helps reduce the risk of ketosis in early lactation, improving metabolic balance and production indices. In beef cattle, it supports growth performance and carcass quality. CLASIX® also optimizes nitrogen utilization, reducing its excretion and improving feed efficiency, thereby making a concrete contribution to the environmental sustainability of livestock farming.
Benefits
- Reduces the risk of ketosis in early lactation, improving the lipid profile and metabolic balance
- Improves fertility and production performance
- Supports protein synthesis, enhancing meat quality
- Optimizes nitrogen utilization, increasing feed efficiency
- Protects against oxidation, increasing the nutritional value of animal-derived products
SIL METHIONINE 50% MICROCAPS
Methionine is an essential limiting amino acid in cattle nutrition: when deficient, the body cannot compensate through endogenous synthesis, with direct effects on production performance and feed efficiency. SIL METHIONINE 50% Microcaps provides methionine in a protected form, allowing for a reduction in dietary protein levels without compromising performance, while optimizing nitrogen utilization, with a concrete reduction in its excretion in manure. In dairy cows, it supports production performance with increased milk yield, improved BCS (Body Condition Score) and higher fat and casein percentages in milk.
Benefits
- Ensures optimal methionine supply bypassing rumen degradation
- Improves production performance and BCS in dairy cows
- Increases milk yield and improves quality by raising fat and casein content
- Optimizes nitrogen utilization, reducing environmental excretion
- Enables the formulation of reduced-protein diets without compromising feed efficiency
SIL CHOLINE 25% MICROCAPS
Choline is an essential nutrient of key importance for hepatic metabolism, promoting the transport of free fatty acids and helping to prevent lipid accumulation in the liver (hepatic steatosis). It helps reduce the risk of metabolic disorders typical of the post-partum period, such as ketosis and mastitis, supporting animal welfare. In its protected form, SIL CHOLINE 25% Microcaps ensures effective rumen bypass and high intestinal absorption.
Benefits
- Supports hepatic lipid metabolism
- Improves milk production and quality
- Promotes animal well-being, reducing the risk of metabolic disorders
OLISTAT™ CYN
OLISTAT™ CYN is a protected source of cinnamaldehyde, known for its antimicrobial and regulatory activity within the gut. The microencapsulated form ensures targeted release in the intestinal tract, where its broad-spectrum action is most effective, thereby counteracting malabsorption conditions, supporting the animal’s resistance to pathogens, and contributing to the reduction of methane emissions, with a positive impact on the farm’s environmental sustainability.
Benefits
- Supports resistance to pathogens, preventing intestinal malabsorption
- Improves production performance
- Reduces methane emissions, contributing to the environmental sustainability of livestock farming
- Mitigates the negative effects of heat stress
SILBUTYR® 60 CWD MR
Intestinal development in the first weeks of life is crucial for cattle performance throughout the entire production cycle. SILBUTYR® 60 CWD MR is a sodium butyrate-based formulation specifically developed for pre-weaning calves: its water-dispersible form makes it perfectly compatible with use in milk replacers. Butyrate exerts a powerful trophic effect on the digestive tract mucosa, stimulating the development and lengthening of intestinal villi and supporting immune system maturation during the most delicate stages of growth.
Benefits
- Exerts a direct trophic effect on the intestinal mucosa, promoting rapid development of villi in length and volume
- Supports the maturation of the immune system in pre-weaning calves
- Improves growth performance, feed conversion ratio, and carcass quality
SIL PP 50% MICROCAPS
Microencapsulated nicotinic acid designed to support the energy metabolism of dairy cows, especially during stressful periods such as the post-partum. SIL PP 50% Microcaps helps prevent ketosis and promotes the reduction of NEFA concentrations, thereby supporting metabolic efficiency and animal well-being.
Benefits
- Reduces ketone bodies and NEFA concentrations in the blood, helping to prevent ketosis
- Supports glycemic balance and metabolic efficiency
- Improves milk production and optimizes its quality
- Mitigates the negative effects of heat stress on production performance
MICROACID® 455
MICROACID® 455 is a complex of microencapsulated organic acids formulated to offer an alternative to the use of antibiotics in animal feed. The protected form allows controlled release in the gastrointestinal tract, promoting a balanced intestinal environment, optimizing nutrient absorption and supporting the animal’s growth performance.
Benefits
- Enhances the antimicrobial action of organic acids
- Improves gastrointestinal health and optimizes nutrient absorption
- Supports growth performance and feed efficiency
- Helps reduce the need for pharmacological treatments
