30 years of experience - for your farm's success.
Over more than 30 years of operation, we have accumulated vast experience and invaluable insights, which we have transformed into the RVAC Science-Based Growth product line.
Why was RVAC Science-Based Growth created?
By observing livestock and talking with farmers, we realized one thing: the market lacked products that would not only treat already sick animals but also ensure systemic prevention.
The RVAC Science-Based Growth line represents our accumulated experience, which we want to share with you. These are not just ordinary supplements. They are scientifically based solutions designed to:
STAY ONE STEP AHEAD OF DISEASES
REDUCE THE NEED FOR ANTIBIOTICS
ENSURE ANIMAL WELFARE
Our philosophy: Prevention = Maximum economic benefit.
As veterinarians, we are guided by the principle that the cheapest treatment is the one that is never needed. Aiming to prevent potential diseases – ranging from respiratory disorders to digestive issues – in the healthiest and most effective way, we have created products that:



RVAC Science-Based Growth is our contribution to Lithuanian farms. It is our way of saying that we are not just suppliers, but partners in your farm’s success. We know what your herd needs because we speak the same language – the language of animal health.

RVAC GOLD
Liquid immunostimulant and feed additive
RVAC GOLD is a potent liquid immunostimulant and feed additive, specifically designed to improve cattle health. This product effectively addresses milk quality issues by reducing mycotoxin levels and somatic cell counts, while simultaneously lowering the risk of cryptosporidiosis and coccidiosis. Its exclusive composition – featuring US-patented Paecilomyces sp. fungi, yeast cultures, and beta-glucans – acts as a natural antioxidant and offers excellent palatability. By using RVAC GOLD, farms can achieve tangible benefits: increased milk yield and dry matter intake, along with reduced veterinary costs due to its preventive effects.
RVAC BRONCHO+
Feed additive for respiratory health
RVAC BRONCHO+ is a specialized feed additive designed to combat lung diseases and respiratory tract infections. It effectively reduces inflammation in both the upper and lower respiratory tracts, dilates the bronchi, and thins thick mucus, thereby facilitating expectoration and regenerating the respiratory epithelium. The unique formula – enriched with peppermint, eucalyptus, lemon, and rosemary oils, as well as echinacea extract – allows for application not only in feed but also via inhalation by spraying the premises. This is particularly beneficial during adverse environmental conditions, such as heat stress, high dust levels, or high ammonia concentrations.


RVAC SynergySorb
Anti-diarrheal feed additive
RVAC SynergySorb is developed as an effective solution to stop diarrhea and normalize the digestive system. It works by absorbing and binding both polar and non-polar toxins, however, unlike other sorbents, it does not deplete the body of essential electrolytes, vitamins, or minerals. Thanks to its lignocellulose and polyphenol content, the additive acts as a prebiotic, promoting the growth of beneficial microflora while inhibiting pathogens. Usage of SynergySorb not only halts diarrhea but also stimulates intestinal peristalsis, improving digestion and nutrient absorption.
RVAC PROBIOTIK
Digestive support feed additive
RVAC PROBIOTIK is designed to improve digestive processes and stabilize intestinal microflora. It is particularly valuable for restoring microflora after antibiotic treatment and for preventing metabolic acidosis in ruminants. Containing inactivated bacteria and live yeast (Saccharomyces cerevisiae), the product improves feed digestibility and nutrient absorption. For farms, this yields tangible benefits: calves show noticeably improved appetite and weight gain, while adult animals demonstrate increased productivity and a reduced risk of diarrhea.


RVAC SPIRULINA
Rumen additive for calves
RVAC SPIRULINA is a specialized feed additive focused on activating and developing rumen function in calves. The main active ingredient – blue-green algae (Spirulina platensis), enriched with natural pigments – alters the rumen microbial population and acts as a potent immunostimulant. This helps young animals develop a healthy digestive system more rapidly and strengthens their natural immunity.
RVAC ALMAT20
Alternative to antibiotics
RVAC ALMAT20 is an innovative alternative to antibiotics, designed to ensure the health of calves and other livestock. Its mechanism of action is based on the active ingredient citrocin – a thermally stable “loop-structured” peptide that inhibits DNA transcription in Gram-positive bacteria, acting similarly to the antibiotic colistin. This product not only effectively combats bacterial threats but also enhances animal immunity and productivity, while being highly soluble in both water and milk.


RVAC PROTECTED AMINO PACK
Microencapsulated additive for cows
RVAC PROTECTED AMINO PACK is a microencapsulated feed additive for cows, designed to ensure the amino acid balance in the small intestine. Its rumen-protected methionine and lysine not only optimize liver function by acting as methyl group donors but also directly influence production metrics. By using this additive, farms can achieve higher milk yields and improved milk composition, particularly in terms of fat and protein content.
RVAC ENERGY
Liquid energy supplement
RVAC ENERGY is a liquid energy supplement for cows with glucogenic properties, designed to protect the herd from ketosis. This comprehensive product also serves as a liver protectant, as it is rich not only in glycerol but also in essential vitamins (D3, E, B-complex) and trace elements (iodine, cobalt, selenium). It is recommended to begin using the additive before calving to ensure a smooth transition period and optimal body condition.


RVAC PectoPOV
Dietary feed supplement for calves
RVAC PectoPOV is a specialized dietetic feed supplement for calves, designed for the rapid stabilization of the digestive tract during periods of diarrhea risk, illness, or recovery. Its mechanism of action relies on pectins and specially modified starch which, upon swelling, absorb excess moisture and form a protective layer over the intestinal mucosa. This not only provides physical protection for the gut but also effectively prevents dangerous dehydration through its included electrolytes. Easily digestible nutrients help maintain the animal’s vitality, making it an highly effective tool for reducing diarrhea risk and ensuring calf health.
RVAC RUMENBUFF
Dietary solution for ruminant acidosis
RVAC RUMENBUFF is a comprehensive dietary solution designed for the effective management of ruminant acidosis and rumen function disorders. Its exclusive synergistic formula combines potent buffering agents (sodium bicarbonate, magnesium oxide) with live yeast to stabilize pH and restore rumen microflora. The product is unique for its enrichment with specific plant extracts (gentian, centaury) that naturally stimulate appetite and rumination, alongside essential trace elements (zinc, manganese, cobalt). By using RVAC RUMENBUFF, the digestive process is optimized, ensuring stable herd productivity.


RVAC TARITRAL
Liquid feed supplement for the dry period
RVAC TARITRAL is a specialized liquid feed supplement developed to facilitate the drying-off and weaning processes in dairy cows, goats, and sheep. The product is based on a synergistic blend of plant extracts (sage, horsetail, nettle) and minerals that help naturally reduce milk secretion. The included magnesium effectively manages the stress caused by dietary changes, while zinc promotes tissue regeneration, preparing the udder for the rest period and protecting its health. It is an indispensable tool for ending lactation quickly and without stress, particularly recommended for high-yielding animals where sudden cessation of milking causes discomfort.
