‘Immunity Challenge’ Studies 11 Years Of Data From 650,000 Cows

To show the effectiveness of OmniGen in helping to maintain a healthy immune system in dry, pre-fresh and lactating dairy cattle, Phibro conducted on-farm demonstrations over 11 years with more than 650,000 dairy cows. The data were compiled from dairies in the OmniGen Immunity Challenge field studies between 2007 and 2018. ( File Photo )

No matter what stage of lactation a dairy cow is in, her health is closely tied to producer profitability. Throughout the lactation cycle, cows are exposed to stressors that have a negative impact on the immune system, increasing the risk of infection and disease — and treating these issues can raise input costs. Phibro Animal Health designed the OmniGen family of nutritional specialty products to help dairy cows maintain a healthy immune system for improved health during all phases of lactation, according to James Chapman, Ph.D., Senior Research Leader, Collaborative Research for Phibro.

To show the effectiveness of OmniGen in helping to maintain a healthy immune system in dry, pre-fresh and lactating dairy cattle, Phibro conducted on-farm demonstrations over 11 years with more than 650,000 dairy cows. The data were compiled from dairies in the OmniGen Immunity Challenge field studies between 2007 and 2018.

Throughout the demonstration, participating dairies were supported by a Phibro dairy team member who helped evaluate and assess herd health and milk production. OmniGen nutritional specialty product was added to feed formulations and fed to all dry and lactating cows for 90 to 120 consecutive days.

Records were monitored for mastitis, ketosis, milk output, somatic cell count and death, among other parameters.
While demonstrations were conducted and data was collected over a broad range of years, number of cows and geographies, specific health results demonstrated the impact a healthy immune system has on cow health and input costs associated with veterinary visits, treatments and mortality:
•    Mastitis cases declined by 12.6% (based on 550 herds reporting)
•    Metritis incidence in fresh cows declined by 20.9% (389 herds reporting)
•    Ketosis in fresh cows was down by 18.5% (257 herds reporting)
•    Retained placenta cases in fresh cows dropped by 19.8% (413 herds reporting)
•    Death loss declined by 17.2% (727 herds reporting)
