Quality Consistency Purity Safety
Since 1960 established as Poultry Health Laboratories, PHL produced many number of vaccines for farm animals and even domestics pets and exotic birds. While chickens and turkeys occupied the majority of the early efforts of the company, our autogenous products were also a key component in making the company successful. PHL was the first company in the country to produce a parvovirus vaccine for dogs. We developed a tissue culture technique that is still actively used today as the most effective way to make many vaccines.
Today as needs change and vaccine companies along with it, we are proud to say we work exclusively with Zoetis in the manufacture of the No. 1 E. coli mastitis vaccine, Zoetis ENVIRACOR J-5. It provides a safe and effective way to help control clinical signs associated with E. coli mastitis. By sticking with a single product, it allows us to concentrate on every vital area needed to produce the very best E. coli mastitis vaccine available today. The transition from avian to bovine from 20th to 21st century attests to the uncompromising excellence we’ve maintained since inception.
