Bimeda USA launches generic topical parasiticide for beef and dairy cattle

Bimeda has expanded its anti-parasitic portfolio with the addition of MoxiSolv Pour-On (moxidectin), an FDA-approved, bioequivalent alternative to Cydectin Pour-On (moxidectin) by Elanco. It is labeled for use in beef and dairy cattle of all ages – including lactating dairy cows – for treatment and control of gastrointestinal roundworms, lungworms, cattle grubs, mites, lice and horn flies.

Collaborators to study bioactive compounds and livestock health

By leveraging in vitro cell models targeting different organs and tissues, the partnership – called SCAN – will explore the effects of bioactive compounds on nutrition, immunity, metabolism and livestock performance. The collaborators are CCPA Group (developer of feed and formulation), Lallemand Animal Nutrition, and the “Membrane and Metabolic Stress” technical platform of IRSET, the Research Institute for Environmental and Occupational Health — University of Rennes in France.

Can biomarkers identify skeletal stress in racehorses?

Researchers from Perth, Australia-based TeleMedVET report that concentrations of serum osteocalcin were higher in lame horses than those who were clinically sound. A recent peer-reviewed study was published in the Equine Veterinary Journal. The group said it will now focus on following individual horses through training and competition to better comprehend the relationships between osteocalcin, workload, skeletal adaptation, lameness and injury.

ECO gets FDA green light to license poultry vaccine

ECO Animal Health Group plc announced that the U.S. Department of Agriculture Center for Veterinary Biologics has confirmed that the company’s U.S. field safety trial data for ECOVAXXIN MS, its poultry vaccine against Mycoplasma synoviae, fulfills the requirement to support licensure of the product. U.S. marketing approval is expected for ECOVAXXIN MS by the end of the calendar year.

USPOULTRY reports promising approach to improve rHVT turkey vaccines

Recombinant herpesvirus of turkey (rHVT) vaccines present a challenge to producers because they are cell-associated, meaning the vaccine virus is contained within living cells. This can make it more difficult to achieve consistent vaccine production and uniform dosing at the hatchery. A recent study conducted by Dr. Isabel Gimeno at North Carolina State University College of Veterinary Medicine and colleagues found that using a novel Diploid Growth Serum Reduced (DGSR) medium increased vaccine titers fivefold, improved infectivity by 300% and reduced dose variability by half compared with conventional media.

Scientists test new weapon against New World screwworm

The Foundation for Food & Agriculture Research and the University of Notre Dame are investing $140,389 to determine whether nitisinone, a drug already approved for human use, can kill New World screwworm larvae. Research has shown that nitisinone kills several blood-feeding arthropods — including mosquitoes, ticks, kissing bugs, bed bugs, tsetse flies and stable flies — by blocking a key enzyme the insects need to digest blood. That same enzyme is present in screwworms.
