Bovi-Shield GOLD 5 is a freeze-dried preparation of modified live virus (MLV) strains of IBR, BVD (Types 1 and 2), PI3, and BRSV viruses, plus a sterile diluent used to rehydrate the freeze-dried vaccine. Viral antigens are propagated on established cell lines.

The vaccination with a modified-live virus (MLV) is currently a well-accepted procedure in the BVD control programs in most of the European countries and is considered a complementary biosecurity tool in countries with high BVD prevalence, in order to prevent infection and re-infections in cattle herds [11].

2013年2月25日 · Used properly, modified-live vaccine corrals diseases and prevents reproductive problems. By following the modified-live vaccine (MLV) label when vaccinating cows and first-calf heifers, producers can prevent diseases that can cause …

2006年5月15日 · Objective —To compare the efficacy of modified-live virus (MLV) vaccines containing either type 1 bovine viral diarrhea virus (BVDV) or types 1 and 2 BVDV in protecting heifers and their offspring against infection associated with heterologous noncytopathic type 2 BVDV challenge during gestation. Design —Randomized controlled study.

For cattle producers, BOVI-SHIELD GOLD FP® 5 provides protection for heifers and cows from reproductive and respiratory forms of infectious bovine rhinotracheitis (IBR) virus and bovine viral diarrhea (BVD) Types 1a, 1b and 2 strains as well as respiratory disease caused by parainfluenza 3 (PI 3) virus and bovine respiratory syncytial virus ...

BOVI-SHIELD GOLD® 5 is a modified-live virus used for the vaccination of healthy cattle to help prevent disease caused by infectious bovine rhinotracheitis (IBR) virus, bovine viral diarrhea (BVD) Types 1a, 1b, and 2 viruses, parainfluenza 3 …

Currently, modified-live viral (MLV) and inactivated viral vaccines are available against BVDV, often in combination with other viral and bacterial antigens. Inactivated and MLV vaccines provide cattle producers and veterinarians safe and efficacious options for herd immunization to limit disease associated with BVDV infection.

Vaccinate heifers initially with a modified-live BVD vaccine Booster in 2-4 weeks with a modified-live or killed BVD product Booster annually (MLV to open animals only), or semi-annually (killed). Depending on vaccination history, all purchased animals should be vaccinated against BVD at least once, and possibly twice.

2020年7月7日 · Control of bovine viral diarrhea virus (BVDV) in cattle populations across most of the world has remained elusive in spite of advances in knowledge about this viral pathogen. A central feature of virus perseverance in cattle herds is …

Effects of a modified live vaccine (MLV) strain of bovine viral diarrhea virus (BVD) on lymphocyte and neutrophil function were determined in cattle with and without increased plasma cortisol (hydrocortisone) concentrations.
