Researchers use Vitamin D to fight coccidiosis in turkeys

USPOULTRY and the USPOULTRY Foundation have announced the completion of a funded research project at the Ohio Agricultural Research and Development Center in Wooster, in which researchers looked at the role of vitamin D in fighting coccidiosis in turkeys. The research project has been designated as the Virgil H. Cooper Turkey Fund 2014 award and is part of the association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report, along with information on other association research, may be obtained by going to www.uspoultry.org.
The project summary is as follows:
Project #689: 25-OH Cholecalciferol (HyD) Supplementation to Improve Anti-Coccidial Defense in Turkeys 
(Dr. Ramesh Selvaraj, Ohio Agriculture Research and Development Center)
Dr. Selvaraj and colleagues found that supplementation of turkey feed with increased levels of a form of vitamin D, 25-OH cholecalciferol, improved body weight gain and decreased the fecal shedding of coccidial oocysts following coccidia challenge. This novel approach to controlling coccidiosis may prove useful for production programs which rely less on the use of anticoccidial compounds.

Zoetis introduces Rotecc Coccidiosis-Management Initiative

    Zoetis Inc. introduced Rotecc Coccidiosis Management, a new, science-based initiative to help poultry producers worldwide develop more strategic, cost-effective and sustainable programs for battling the costly parasitic disease.
    "Overall, the poultry industry has done a commendable job managing coccidiosis. But clearly, when you look at billions of dollars in losses associated with the disease, there is still lots of room for improvement," Mark LaVorgna, Ph.D., a nutritionist and global technical services director for the company, said at a news conference in Atlanta before the 2014 International Production and Processing Expo.
    Rotecc begins with a consultation by a Zoetis representative, who reviews a poultry operation's past and current programs, necropsy data and results from anticoccidial sensitivity testing, as well as seasonal preferences for product usage, production goals and management practices. Other variables such as feed costs and meat prices also are considered.
    Rotecc is built on best practices widely accepted by the poultry science community for coccidiosis management. Specifically, this includes not using the same in-feed anticoccidial for too long, rotating among products from different classes, resting each product and using a synthetic anticoccidial once yearly to clean up lingering coccidia and help reduce infection pressure.
    Don Waldrip, D.V.M., senior technical services veterinarian for the company, with years of production experience, said poultry producers would benefit from thinking longer term - perhaps even 24 months ahead - when developing their coccidiosis-management programs.
    To support Rotecc, Zoetis is developing several digital tools to help producers and veterinarians tailor a long-term program to suit their individual needs. These include the Rotecc Program Advisor, an iPad app that initially will be available in the U.S., and a Rotecc Calculator, which will run on the iPad and Windows operating systems. It will be used to help determine the most cost-effective anticoccidials for each producer's rotation plan while adhering to best practices for rotation.

Coccidiosis can play a role in Salmonella control

    Coccidiosis control continues to be a top concern for broiler veterinarians in the U.S., in spite of the estimated $90 million per year spent on prevention, according to Dr. Greg Mathis, president and researcher, Southern Poultry Research, Inc. Mathis, speaking at WATT Global Media's "Coccidiosis vaccination: A new approach to Salmonella control" webinar, said that broilers vaccinated for coccidiosis have lower lesion scores than do birds treated with either chemical coccidiostats or ionophores.
    Mathis said that there are nine species of coccidia that impact broilers, with E. acervulina, E. tenella and E. maxima being the most prevalent. E. tenella is primarily found in the ceca and it is the species of coccidia that seems to affect Salmonella levels in broilers the most. Mathis said that better control of E. tenella may lower Salmonella incidence in a flock at time of market.
    Impact of vaccination
    Dr. Charles Hofacre, researcher, poultry diagnostic research center, University of Georgia, said that coccidiosis vaccination is regaining popularity with broiler companies for a number of factors. Resistance of coccidia populations in broiler houses to both chemical coccidiostats and ionophores continues to be a growing problem with no new drugs introduced in the last few decades. Hofacre said that vaccinating for coccidiosis reestablishes populations of susceptible strains of coccidia on broiler farms. Finally, he said that the growth of the antibiotic-free movement among some consumers has also increased use of coccidiosis vaccines.
    Research has shown that coccidiosis breaks in broilers associated with E. necatrix and E. tenella are associated with increases in Salmonella colonization in the bird. Hofacre said the E. necatrix control in breeders plays a role in helping to keeps Salmonella loads on chicks low, but that E. tenella control is of more importance for controlling Salmonella colonization in the broiler house.
    Coccidiosis control and Salmonella
    Hofacre reported on a challenge study where birds were raised on built up litter and where either vaccinated for coccidiosis or treated with an ionophore coccidiostat, Salinomycin. In addition to being raised on built-up litter, half of the birds in this study were challenged with Salmonella Heidelberg. Salmonella Heidelberg levels were numerically lower in the drag swabs of the pens with vaccinated birds. The vaccinated broilers had lower cecal Salmonella counts than did the Salinomycin treated birds.
    "Coccidia vaccine in this study numerically reduced environmental load, prevalence and cecal number of Salmonella Heidelberg," said Hofacre. Coccidiosis control alone won't solve Salmonella problems for a broiler producer, but it can contribute to the solution. "We reduce Salmonella not by silver bullets but by multiple methods that build to success."

Feed ingredient may manage coccidiosis in broilers, according to study

    Independent studies found that Original XPC many help manage coccidiosis in broilers. Original XPC is a feed ingredient from Diamond V, a fermentation product manufacturer.
    The effects of Original XPC and a coccidiostat (Salinomycin) were investigated individually and in combination at Southern Poultry Research during a coccidiosis challenge in broiler chickens. A total of 320 test birds were housed and lesion scores were conducted. Male broilers (Cobb X Cobb) were used from zero to 27 days of age. All birds received vaccinations at the hatchery for Marek's Disease (HVT:SB-1) and birds were weighed at zero, 21 and 27 days of age. Feed consumption was measured at 21 days and 27 days. The study included five treatments with eight birds per cage and eight replicate cages per treatment. Test articles were added to the feed of each treatment.
    All birds except the negative controls were challenged orally with a coccidia inoculum at 21 days. The challenge dose per bird was designed to be much greater than a routine field challenge and to produce approximately 3.0 lesion scores for each species in the infected, non-medicated control group.
    At 27 days, all birds from each cage were lesion scored. The upper, middle and cecal regions of the intestine were scored, using the system of Johnson and Reid where 0 is normal and 1, 2, 3, or 4 indicate increasing severity of infection.
    E. acervulina coccidia lesions sores were reduced in the upper gastrointestinal tract when Original XPC was included in the feed. Salinomycin inclusion further reduced lesions compared to the non-medicated, infected group. E. maxima lesion scores in the mid gut were also significantly reduced with the addition of Original XPC to the diets, and the response was equivalent to that of Salinomycin and to the combination of products. Cecal lesions reflecting E. tenella were also significantly reduced when feeding Original XPC, and an even greater response was observed when Salinomycin was included.
    Body weight gain during the coccidiosis infection was severely affected in the non-medicated, infected group. Adding Original XPC to the feed significantly improved body weight gain, and Salinomycin produced even greater gain. The combination of Original XPC and Salinomycin provided the greatest weight gain among the infected groups.
    The treatment response for feed conversion ratio was similar to body weight gains. Significant improvement was seen both with Original XPC and Salinomycin. Combining Original XPC and Salinomycin resulted in feed conversion similar to that of non-infected controls.
    Previous research had suggested that the metabolites in Diamond V Original XPC empower the bird's immune system by strengthening the instinctive immune response and supporting adaptive immunity within the gastrointestinal tract. In addition, chemical signals help suppress the inflammatory response during a challenge, and metabolites in Original XPC increase antibody production to commercial vaccines.
    Previous work also demonstrated that feeding Original XPC can reduce the incidence and severity of intestinal lesions when birds are challenged with coccidiosis. Further evidence of reduced coccidiosis stress from feeding Original XPC is the improved body weight gain and feed conversion when birds are fed Original XPC during a coccidia challenge.

Alternative method to manage coccidiosis proven in test


    Scientific evaluation of the different alternative solutions for coccidiosis management in broilers has shown that Oilis allows the best European Performance Index during the recovery period and optimum nutrients' assimilation.
    Coccidiosis is a very common pathology in broiler houses actually controlled by antibiotic coccidiostatic products. Due to increase of microbes' resistance to antibiotics, the tendency now is to reduce their use in animal farming. Because of that, there is growing need for alternatives to those antibiotic products.
    In this context, the current study is aimed to compare the efficiency of different non antibiotic products for broiler chickens affected by coccidiosis.
    Oilis, Neovia's natural alternative solution for coccidiosis, has been tested among its competitors' products on a specific challenge model developed by Neovia, where birds are inoculated with three different strains of Eimeria species to generate clinical coccidiosis The results of the study performed on 660-day old chicks are synthetized on the following poster presented during 10th Poultry Research Days in France. They prove that Oilis group obtained the best performances in general and especially during the recovery period.
    Furthermore, intestinal lesions in different part of intestinal tract are reduced by Oilis allowing faster recovery and thus a better nutrients' assimilation. This is also clearly illustrated by the significantly higher plasmatic coloration obtained in the Oilis group.
    To conclude, this trial demonstrates that Oilis is able to limit the impact of coccidiosis in broiler chicken farms. Efficiency and mode of actions of products proved to be very variable, confirming the necessity to evaluate the different products on suitable targeted models.
    In this context, Oilis allows the best European Performance Index, especially in the recovery period and optimizes assimilation of nutrients.

Poultry industry needs, consumer demand topics at Alltech symposium


    From problems with mycotoxins and coccidiosis, to opportunities with epigenetics and antibiotic-free programs, Alltech plans to address a plate full of topics that affect the poultry industry, from the hatchery to the dining room, at GLIMPSE 2020: the 29th Annual Alltech International Symposium in Lexington, Ky., May 19-22.
    New in 2013, Alltech International Symposium delegates will have the opportunity to select breakout session tracks. These tracks, as opposed to traditional species or subject breakouts, will offer attendees a more holistic experience in which they take part in discussions ranging from algae and agriculture's carbon footprint to nutrition and marketing.
    "With daily blogs, tweets and posts demanding cage free, farm fresh and organic products, we need to listen to what consumers are saying, determine the best route to market and meet their expectations. At this year's Symposium, we will look at opportunities to improve meat quality and the customer experience by further investigating parameters such as tenderness, drip loss, cooking loss and shelf life," said Paulo Rigolin, chairperson for the poultry antibiotic-free track at Symposium. "It is more critical than ever to shift from the mindset of 'just being in the poultry business' to recognizing our role in a food industry that must feed an additional billion people by 2020."
    Poultry-focused breakout session tracks include:
    • Epigenetics: The Role of Parental Nutrition in Shaping Offspring Health
    • Eggs: The Perfect Nutrient in the Perfect Nutrient Delivery System
    • Reimagining Nutrition Part 1: The Role of Solid State Fermentation to Reduce Diet Costs
    • Coccidiosis Control: Confronting the Reality in an Era of Fewer Viable Options
    • Gut Immunity and Homeostatis: How Intestinal Microflora Interacts with the Immune System and Disease
    • Unlocking Genetic Potential with Natural Nutrition
    • Mycotoxins: The Global Picture
    Poultry industry members will also get the opportunity to network in the discussion forum and explore questions such as:
    • Crisis Management- How Will Your Firm Handle a Crisis?
    • Branding Food: Is it Niche or Mainstream?
    • Reimagining Nutrition: How Nutrigenomics is Revolutionizing How We Feed
    • Is Truly Antibiotic-Free Animal Production Possible?
    Registration for Alltech's 29th Annual International Symposium is open now and available for an early discount price of $599 until April 15 at 11:59 p.m. EST. Standard registration after April 15 will be $850. Two paid registrations from a single company or organization will receive a third registration free of charge. Delegates who are members of ARPAS and AAVSB can also earn CEUs.
    Attendees are encouraged to register early as space is limited. Of the nearly 3,000 international delegates who attended the 2012 Alltech International Symposium, 97 percent indicated that they plan to attend again.
    For more information, or to request an invitation, contact a local Alltech representative, visit www.alltech.com/symposium or email symposium@alltech.com.

Ceva rapid growth expected to continue in 2013


    Ceva Holdings, Inc. affirmed its continued growth in 2013 for the North America market following the financial reporting results of its parent company, Ceva Santé Animale. The company completed its consolidation of its North America headquarters operations to the Lenexa, Kan., campus in late fall 2012. The move expanded the company workforce and has already resulted in better synergies to serve customers more efficiently for both its Ceva Animal Health and Ceva Biomune subsidiaries.
    In 2012, Vectra parasiticide sales grew 34.5 percent in the US. Feliway and Adaptil continued to drive expansion of the behavior segment growing 30.4 percent. The company also entered the equine market in the United States with the launch of Altresyn (altrenogest).
    In the avian market, Ceva captured the number two market position in 2012 after the successful conclusion of Ceva’s integration of Vetech Laboratories, a Canadian poultry vaccine manufacturer that markets live vaccines against coccidiosis. This allowed Ceva to add Vetech’s live coccidiosis vaccine Immucox T to the portfolio in the highly competitive United States market, expanding the poultry vaccine range from respiratory to also include intestinal health.
    “We are coming off a very strong year and believe Ceva will continue growth with an outstanding team in place, with great existing and new products, and with continued financial support and commitment to the veterinary profession, “said Craig Wallace, Chief Executive Officer of Ceva Holdings, Inc.
    Demonstrating Ceva’s commitment to grow its management team, Dr. Karen Padgett joined Ceva January 1 as Chief Operating Officer of the Ceva Animal Health Companion Animal Group. Padgett is a 28-year veteran of the animal health industry, most of which has been spent at Hill’s Pet Nutrition, a division of Colgate-Palmolive.
    Upon being named to the position, Dr. Padgett said, “Ceva is a global company that is rapidly growing, but shows true commitment to the veterinary profession. I am thrilled to join the organization to lead a dynamic team and continue to contribute to the veterinary profession in a meaningful way. It’s a tremendous opportunity.”
    The company plans to not only continue to market its products aggressively, but help educate pet owners to drive traffic to veterinary clinics. The Vectra brand will be supported in 2013 by a multi-media advertising campaign which includes television advertising and a "first dose free” coupon program.
    The Feliway line will be extended with the introduction of new Feliway Wipes at the Western Veterinary Conference. Both Adaptil and Feliway will be supported by a major nationwide Behavior Advocate Program and veterinary exclusive trial generating consumer programs. In addition, the successful public relations bus tour will be expanded. The tour is aimed at increasing awareness that there are solutions to help keep pets from being put down due to unwanted behavior issues.
    Ceva Animal Health has increased its visibility in the veterinary profession by joining in the celebration of the American Veterinary Medical Association’s 150th Anniversary as a sponsor. The company is also a sponsor of the One Health, One World initiative, is an inaugural sponsor of the American Association of Feline Practitioner’s Cat Practice initiative, and continues its commitment to educating veterinarians through conference CE and a new state veterinary medical association program.
    Ceva Biomune’s $7 million renovation to its research and development facility in Lenexa announced in July 2012 is expected to be completed in June, 2013. The renovation will give the team 18,000 square feet of bio safety level 2 laboratory space and 15,000 square feet of office space. In May 2011, Ceva completed an $18 million expansion of its Biomune poultry vaccine production plant on the Ceva Biomune campus.
    “Continued expansion of our research and manufacturing facilities is critical to meeting the needs of our domestic and global customers. We are on schedule to deliver on that investment and look forward to the opening of the renovated research and development facility,” said Daryl Pint, Chief Executive Officer of Ceva Biomune.
