Varium®’s Long History of Boosting Poultry Performance Expands with New Swine Study

Varium® and its sister product, NeoPrime, were developed as non-antibiotic alternatives to improve production by optimizing gut health in poultry and swine respectively. Amlan has decided to streamline product offerings, research shows Varium’s patented blend of natural ingredients can provide equal benefits in swine. In a recent study, Varium improved feed conversion, reduced mortality rates and improved the overall well-being and performance of swine on a commercial farm in Mexico.

Weaned piglets are particularly susceptible to digestive disorders that can lead to poor performance.  Weaning is a critical stage for piglets, as their digestive systems are still developing and highly vulnerable to disruptions. The abrupt change in diet, combined with the stress of separation from the sow, often leads to digestive disorders like post-weaning diarrhea. These conditions can hinder nutrient absorption, weakening the piglets’ immune system and overall health. This reduction in performance early in life creates a fallback lag for the challenged piglet, which follows the animal all the way to maturity. Piglets left unsupported during weaning display lower market weight as this extended period of decreased feed intake, poor nutrient absorption, and diminished weight gain hinders healthy and efficient growth early in life. This, in turn, negatively affects the bottom line of producers worldwide. To mitigate these challenges, it is important to implement strategies to support gut health during this transition to maintain the health and performance of weaned piglets.

The patented technology of Varium offers a synergistic blend of ingredients designed to address the key challenges faced by weaned piglets. Varium was specifically designed with 3 unique modes of action to improve performance and reduce the challenge an animal faces when exposed to pathogenic bacteria and toxins. Varium works by binding pathogenic bacteria and their toxins,  protecting the gut from intestinal damage linked to performance loss, and provides an energy source to fuel the growth of healthy enterocytes vital for nutrient absorption. Additionally, it supports immune cell heath and function ensuring that the animal’s natural immune system is operating in an optimal state. Proven effective in the market for over the past 10 years, Varium was tested in a 148-day trial on weaned piglets, delivering promising results in promoting gut health and overall performance.

This trial compared the performance of 180 weaned piglets, randomly distributed in blocks of 90 males and 90 females between two treatments: Diet formulated with Varium, and diet formulated without Varium. The parameters for success included daily feed intake, average daily weight gain, feed conversion, mortality and diarrhea incidences. In all categories, the Varium group showed improvements over the control group.

Feed Conversion

 

Pigs that were fed Varium showed a advantage in feed conversion over the control group, most notably during feeding phases 3 and 6.

 

Mortality Rates

 

Mortality rates showed the most notable difference during phase two, when pigs fed Varium showed a mortality rate that was more than 60% less than the control group. The accumulated mortality rate over 7 phases for the Varium group showed a 43% reduction in mortality rate when compared to the control.

 

Diarrhea Incidence

 

The addition of Varium to the pigs’ diet cut the incidences of both pasty and liquid diarrhea in half, indicating an improvement in intestinal integrity provided by Varium.

 

Body Weight

 

After 148 days, pigs in the Varium group weighed an average of 9% more than those on the control group, further supporting Varium as a beneficial addition to pigs’ diet.

 

Feed Intake

 

The Varium group showed lower feed intake at all 7 stages over control. This, combined with improved feed conversion rates and higher live weights indicate a more efficient use of feed from the Varium group.

Improved Feed Efficiency and Gut Health is a Beneficial for Producers

Weaned pigs fed Varium in this study simply performed better than the control group. The improvement in feed conversion, along with the positive trend in body weight and reduction in mortality, suggests that Varium can be an effective tool for improving herd health and overall performance in swine.

Tackling the Combined Impact of Necrotic Enteritis and Aflatoxin Co-Challenge

In a recent blog post on the cumulative effect of multiple mycotoxins, we discussed how, in reality, animals are more likely to be affected by multiple mycotoxins in their feed, unlike a single mycotoxin typically studied in research. In the real world, animals are likely to encounter both mycotoxins in their feed and bacteria in their environment simultaneously. To demonstrate this, Amlan funded research that compared a Necrotic Enteritis (NE) challenge with a co-challenge of Necrotic Enteritis and Aflatoxin (NE+AFL) published in the Journal of Applied Poultry Research 

Necrotic Enteritis is a common infectious disease in broiler production which has increased in incidence in recent years due to the reduction in the use of antibiotics. Toxins produced by Clostridium perfringens have been identified as the causative agents of NE along with a coccidiosis challenge.  Aflatoxin is a very common mycotoxin that contaminates feedstuffs worldwide. It decreases feed intake and gain as well as causing a general decrease in immune function. This decrease in immune function and general gut damage caused by AFL enables AFL to increase the effects of intestinal diseases such as NE. 

Calibrin®-Z, an all-natural feed ingredient available in select international markets from Amlan® International, has shown the ability to decrease the effects of a broad spectrum of mycotoxins as well as the ability to bind exotoxins and endotoxins produced by bacteria, like the toxins produced by C. perfringens known to cause NE.  For this reason, Calibrin-Z was used in this research study compared to Virginiamycin, a traditional antibiotic used in the poultry industry. 

In this study, there were three challenges: No challenge (control), Necrotic Enteritis challenge (NE), and Necrotic Enteritis + 1.0 ppm aflatoxin (NE+AFL). Each challenge was conducted with control birds (no product), birds with Calibrin-Z (0.5%) in the diet, and birds with Virginiamycin (22 ppm) in the diet.  Eight replicate pens of 22 males of a common breed were placed in floor pens at day of age and grown to 24 days of age. The AFL challenge diets were created by the addition of purified Aflatoxin to the diets. The NE challenge was induced by placing challenge groups on used litter from birds challenged with C. perfringens cultures while non-NE challenged birds were placed on clean litter.  At day 10 the NE challenged birds were given a 10X dose of coccidiosis vaccine. 

As expected, the Body Weight performance worsened with the inclusion of the NE challenge from the control and again with the inclusion of the AFL challenge on top of the NE challenge (NE+AFL).  For Feed Conversion the NE challenge alone did not statistically worsen FCR, however, the NE+AFL challenge was statistically higher than the NE challenge alone. 

Virginiamycin, as an antibiotic commonly used to prevent or treat NE, was very successful in improving KPI’s in the NE-challenged birds, but was less successful when the AFL challenge was added on top of the NE (NE+AFL). Calibrin-Z, however, numerically improved performance in the NE-challenged broilers and statistically improved performance for both Body Weight and FCR in the broilers challenged with both NE and AFL. When FCR is adjusted to a common body weight to account for the reduced weights from the challenge (adjustment = 1 pt FCR per 30g BW), the Calibrin-Z fed broilers performed 3 points better than the Virginiamycin fed broilers and 7 points better than the NE+AFL challenged control broilers. 

 

During a Necrotic Enteritis challenge in the field, Virginiamycin or Calibrin-Z can both help to decrease the effects of the challenge. In today’s world, where antibiotic usage is being reduced through NAE (No Antibiotics Ever) or NAIHM (No Antibiotics Important for Human Medicine) programs, or simply through responsible product rotation, Calibrin-Z offers an effective natural alternative. It matches the effectiveness of commonly used antibiotics due to its inherent ability to bind the toxins produced by C. perfringens. 

With the addition of Aflatoxin in the feed to challenge the broilers concurrently with NE, which is more common in the real world than any of us wish to believe, the negative performance effects of the NE challenge were significantly increased. Calibrin-Z proved a distinct performance advantage over the antibiotic alone.

Understand How Calibrin®-Z Controls T-2 Toxin in Broilers

Poultry producers mostly know T-2 toxin by the horrific lesions seen on the beaks of poultry. The fast-acting T-2 toxin has a major impact on the growth and performance of poultry and livestock. Luckily it is not the most common trichothecenes toxin produced by Fusarium molds, deoxynivalenol would fill that spot, but T-2 is considered the most toxic of the trichothecenes. This poison can be inhaled or adsorbed through the skin or the gastro-intestinal tract and causes multiple problems in poultry and livestock. A short list of problems includes decreased gain and feed efficiency, decreased egg production and hatchability, decreased immune function, and increased mortality. It has been shown to have a synergistic negative effect with other mycotoxins in the diet or when administered in conjunction with lipopolysaccharide (aka LPS). This may be one reason why there is additional negative impact when there is a co-challenge with T-2 and gram-negative bacteria. Control of other dietary mycotoxins or LPS concurrently with T-2 may be important in any attempt to decrease its effects.   

 

T-2 toxin decreases the productivity of poultry and livestock by inhibiting protein synthesis at the cellular level and causing cell death. In eukaryotic cell’s DNA, RNA, and protein, synthesis is inhibited by T-2 toxin. It also induces apoptosis or programmed cell death.

A major concern in poultry is how T-2 affects the gastrointestinal tract starting with lesions of the beak and gizzard and going through the entire gut. These lesions will affect feed intake, gain, and feed efficiency. But T-2 can affect all aspects of production and reproduction, so egg production and hatchability also need to be considered. In early research looking at the effects of T-2 on hatchability, 2 ppm of T-2 toxin was fed to laying hens, egg production decreased by 3.8 percent, fertility of the eggs that were laid decreased by 1.7 percent, and hatchability of fertile eggs decreased by 5.6 percent. This is a substantial loss of hatched chicks because of the toxin in the feed.

T-2 is quickly adsorbed. And it can be adsorbed through the lungs, the skin, or through the gastrointestinal tract when ingested in the feed. Approximately 90% of T-2 is adsorbed into the body within 30 minutes of ingestion, but it does have a short half-life of less than 20 minutes. T-2 producing Fusarium molds can occur in feedstuffs either during a warm and moist growing season or during storage under high moisture, especially if stored grains have damage such as broken or cracked kernels. The best option for producers is to use feedstuffs free of all toxins, however, the reality is that this is not always possible. In those cases where feedstuffs are being fed that may contain T-2 it would be beneficial to have a fast-acting toxin binder in the diets.   

Because T-2 is so damaging and so rapidly absorbed, the toxin binder that is used needs to work and work fast. Calibrin®Z, available in select international markets, adsorbed ~70% of T-2 toxin within 1 minute in research looking at speed-of-binding in vitro. This was approximately 24 times faster than the other products used in the trial. Additionally, Calibrin-Z had previously been shown to bind other mycotoxins and LPS in vitro and in vivo, which may be important during a T-2 challenge. A test to determine the binding ability of Calibrin-Z in vitro was conducted to look at seven common fungal biotoxins where the binder-to-toxin ratio was as if there was 1 kg of Calibrin-Z per metric ton of feed vs. observed concentrations of mycotoxins in feed. In vitro data showed that Calibrin-Z could bind LPS, but it has also been seen in vivo when Calibrin-Z was being fed to laying hens.

Calibrin-Z Mitigates the Effects of T-2 Toxin in Broiler Chicks

Recently, research was conducted at a large university in Brazil to determine the effects of Calibrin-Z on broiler chickens challenged with dietary T-2 Toxin. For this experiment, a total of 180 one-day-old male Cobb 500 broiler chicks were used. At the beginning of the trial the birds had an average body weight of 47 grams, with the average initial weight for each bird being equal. They were fed three different treatments 1) Unchallenged Control; 2) Challenged Control with 2 ppm T-2 Toxin; and 3) 2 ppm T-2 Toxin with 0.5% dietary Calibrin-Z. They were fed the treatment diets for 21 days. No aflatoxins, deoxynivalenol, diacetoxyscirpenol, fumonisins, ochratoxin A, T- 2 Toxin or zearalenone were detected in the feed ingredients that were tested before mixing the diets. The T-2 Toxin that was added to the feed for the challenged treatments was produced by Fusarium sporotrichioides fungi, and was 82% T-2 Toxin, 18% HT-2 Toxin.  There were 6 pens that were randomly assigned to each treatment and there were 10 chicks in each pen. Chicks had free access to a constant supply of food and water. The diet was corn-soybean meal-based and formulated according to requirements in the Cobb Broiler Management Guide.  

The intent of the study was to determine the effect of T-2 toxin on growth performance of broilers and how the addition of Calibrin-Z helped to mitigate any negative effects. Calibrin-Z is a unique calcium montmorillonite that has been shown to bind toxins, both fungal and bacterial, as well as lipopolysaccharides (LPS).

Feeding Calibrin-Z to the birds challenged with T-2 toxin increased body weight by 5% compared to the birds that were fed diets with T-2 toxin and no Calibrin-Z. This improvement returned body weight to that of the unchallenged control birds. In this experiment, there was no effect of feeding T-2 on feed intake with birds on all three treatments having equal feed intake.

Because there was no difference in feed intake the feed conversion ratio followed the same pattern seen in body weight. Feeding Calibrin-Z to birds challenged with T-2 toxin improved feed conversion by 8 points, with values of 1.50 for Calibrin-Z fed birds compared to 1.58 for birds that only received T-2 toxin in the feed.

While aflatoxin is the mycotoxin best known for its negative effects on the liver, T-2 toxin can also have bad effects. In this study, relative liver weight was higher in the challenged control, 3.33%, compared to the unchallenged control, 2.84%, but feeding Calibrin-Z again mitigated the negative effect of the T-2 toxin, with challenged birds fed Calibrin-Z having a relative liver weight of 2.96%.   

T-2 Toxin is a fast-acting mycotoxin that has a tremendous impact on animal performance. It acts in a synergistic way with challenges from other mycotoxins and lipopolysaccharide. To decrease its impact, you need a fast-acting toxin binder to control T-2 quickly while also controlling other potential problems. Calibrin-Z is a fast-acting multi-toxin binder that has proven results.

Reduce Salmonella Prevalence and Load with NeutraPath®

Salmonellosis is a foodborne pathogen that causes illness and death worldwide. A blended feed additive has been shown to have good effects in vitro on a wide range of Gram-negative and Gram-positive bacteria and in vivo to mitigate the effects of Clostridium perfringens in broilers and E. coli in swine. Thus, it was decided to investigate the ability of the proprietary blend of essential oils, medium-chain fatty acids, and an activated toxin-adsorbing mineral (NeutraPath® available in select international markets) to control Salmonella. In vitro and in vivo research with Salmonella typhimurium and Salmonella heidelberg showed the blend could reduce prevalence and bacterial load of Salmonella in broiler chickens. Based on these in vitro and in vivo data, feeding this blend could be a potential new method to help control Salmonella in broiler chickens and aid in control of pathogens at the farm level. 

 

A Foodborne Pathogen 

Salmonella is a very common pathogenic bacteria that can be passed from animals to humans. The typical symptoms of salmonellosis in humans are diarrhea, fever, and stomach cramps, with the occasional vomiting. Generally, this is mild and doesn’t require medical intervention, but it can be deadly, especially in young children. Worldwide, Salmonella is one of four main causes of diarrheal diseases, with diarrheal disease being the 2nd leading cause of death in children under five. In the United States approximately 1,350,000,000 people are infected annually, ~26,500 people are hospitalized, and ~420 die each year. The very young, the very old, pregnant women, and people with compromised immune systems are generally affected the most.  

According to the World Health Organization, Salmonella, a hardy bacteria, can survive in a dry environment for several weeks but several weeks turns into several months if it is in water.  

 

Sometimes salmonellosis can result from coming in direct contact with animals that carry the bacteria, typically reptiles or birds. There are two species of Salmonella, bongori and enterica. Salmonella bongori is normally associated with cold-blooded animals but can infect humans. Selling tiny turtles (those with shells less than 4 inches long) has been prohibited in the U.S. since 1975 because of their association with salmonellosis in children. Salmonella enterica has more serovars with approximately 80 that can infect humans and animals. With an increase in the popularity of raising your own chickens the CDC (Centers for Disease Control) has issued repeated reminders about the safe handling of chickens, including a reminder “don’t kiss your chickens” because of serious outbreaks of salmonellosis, especially among children, linked to raising chickens in the backyard.

But eating or mishandling raw or undercooked contaminated food is the source of most cases of salmonellosis in humans. Live poultry often don’t show signs of carrying Salmonella even if their intestines contain the pathogenic bacteria. There are multiple ways that birds can be exposed to Salmonella. Exposure can be through contaminated feed, from wild birds or rodents, or from a contaminated barn. It is even possible that poultry may be contaminated before the egg that they hatched from was laid. Hens can have bacteria in the ovary or oviduct and the egg can be contaminated before the shell forms around the egg, meaning that even clean, washed eggs could be contaminated. The Poultry Industry has been working diligently to control this problem and this source of contamination of broiler chickens has declined in recent years.  

 

Even though a majority of the foodborne illnesses due to Salmonella originate from non-poultry sources, twenty-three percent of the Salmonella outbreaks in the U.S. are linked to poultry consumption (16.8% from chicken, 6.6% from turkey) with another 6.3% coming from eggs. Salmonella in the intestine of poultry can lead to contamination of poultry meat during processing. Proper cooking will kill the bacteria, but improper handling may spread bacteria around the kitchen and raw vegetables, undercooked meat or uncooked foods containing eggs (i.e., cookie dough) may still be contaminated with live bacteria. Together the CDC, FDA (Food and Drug Administration), and USDA (United States Department of Agriculture) have a goal of reducing Salmonella illnesses by 25% by 2030. In order to do this, they need to decrease Salmonella infections from all products regulated by the Food Safety and Inspection Service division of the USDA by 25%. One way to help reach this goal is to help minimize the amount of Salmonella that comes into the processing plant making it less likely that contamination of poultry meat will occur.  

Poultry producers need help to accomplish this goal. Research has shown that a proprietary blend of essential oils, medium-chain fatty acids, and an activated toxin-adsorbing mineral (NeutraPath®, Amlan International, available in select international markets) may be of assistance. The blend has anti-virulence effects because of its ability to bind quorum sensing molecules, exotoxins, and endotoxins associated with bacteria. It also has direct bacteriostatic/ bactericidal effects against both Gram-positive and Gram-negative bacteria. Its efficacy has been proven over years of in vitro and in vivo trials at multiple research sites, against multiple bacteria, in multiple animal species.  

In vivo research in chickens showed that the blend decreased the effects of Clostridium perfringens. A summary of the studies showed that it improved mortality, gain, and feed conversion in challenged broilers. In weaning pigs, it was shown to decrease the impact of enterotoxigenic E-coli (F-18+). In the pigs challenged with E. coli the blend improved feed efficiency and decreased frequency of diarrhea. When the fecal microbiome was examined, there was a higher relative abundance of Lactobacillaceae and a lower relative abundance of Enterobacteriaceae. Enterobacteriaceae is a family of Gram-negative bacteria that includes both E. coli and Salmonella. These positive results led researchers to investigate its effects on Salmonella, with research being conducted both in vitro and in vivo.  

 

Salmonella Research 

 

In vitro tests were used to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of NeutraPath against S. heidelberg. Three different concentrations (1, 3 and 5 mg/ml) of NeutraPath with a control of 0 mg/ml were added to samples of an S. heidelberg strain. The MIC of NeutraPath for S. heidelberg was found to be 5 mg/ml. To determine the MBC Salmonella cultures were incubated at 37ºC for 16 hours without agitation. After incubation, bacterial counts were measured by serial dilution. A 30 μl aliquot of each dilution was plated onto lysogeny broth and incubated overnight. The MBC of NeutraPath for S. heidelberg was determined to be 4 μg/ml. These assays demonstrated that the blend has strong in vitro inhibitory and bactericidal activities against this key pathogen.  

Because of the results seen in vitro researchers conducted an in vivo experiment. The researchers wanted to know how the blend would affect the Salmonella prevalence in birds previously challenged with S. heidelberg and fed for a short period of time before sampling.  

After feeding the treatments for seven days, pre-moistened boot-sock swab sampling showed that there was S. heidelberg contamination in 100% of the pens. Cecal digesta samples and cloacal swabs were also collected from 10 of the broilers that had been directly challenged at hatch to determine Salmonella prevalence. The prevalence of Salmonella decreased by 40% in the cecal digesta (83.3% vs. 50.0%) and by 55% (60.0% vs. 26.7%) in the cloacal swabs when the blend was added to the diet for 7 days prior to testing. 

 

Comparable studies were done at second location with another group of researchers to establish that the results from the initial studies could be repeated in other Salmonella serovars. This time studies looked at the effects of the blend on Salmonella typhimurium.  

 

First an in vitro study digestion was used to simulate the crop, proventriculus and intestinal section of the gastrointestinal tract. Each “section” had pH and enzymatic conditions that would correspond to that area of the gut. Adding the antimicrobial blend inhibited the growth of S. typhimurium, reducing the total colony forming units recovered in each section. This positive result meant that an in vivo study was warranted. This time the broilers were started at one day of age. Thirty male broiler chicks were placed on two treatments. The treatments were a challenged control with non-treated feed, or birds fed that diet + 0.25% of the blend. At nine days-of-age chickens were given an oral dose of 106 CFU (Colony Forming Units) of live S. typhimurium. Twenty-four hours after the challenge ceca and cecal tonsils were removed so that they could be evaluated for Salmonella recovery. Both the number of positive samples and the amount of Salmonella bacteria found in those positive samples decreased in the treated birds. Feeding the blend decreased the ceca that tested positive for S. typhimurium by 41.7%, 100% of the tested ceca were positive in birds fed the untreated control compared to only 58.3% of the ceca in the birds that were fed the blend. In the birds that tested positive the total S. typhimurium bacterial load recovered in the ceca also dropped by 1.84 log10 CFU/g compared to the untreated control.

Conclusion 

Around the world foodborne salmonellosis continues to be a problem. Regulators are targeting aggressive goals for salmonella reduction in poultry meat. A proprietary blend of essential oils, medium-chain fatty acids, and an activated toxin-adsorbing mineral has been shown to work against a variety of bacteria. Research has shown efficacy against C. perfringens, E. coli, and S. typhimurium and S. heidelberg. Based on the current in vitro and in vivo research adding the blended product has the potential to reduce Salmonella colonization in broiler chickens. This is a viable option for use in poultry health programs including those controlling Salmonella contamination. To learn more about NeutraPath or to contact a local representative, visit amlan.com.
