Research Demonstrates Benefits of OmniGen-AF® in Protecting Lactating Dairy Cows during Heat Stress
Poster presentation selected as “Presidential Pick” at ADSA-ASAS meeting
QUINCY, Ill. (July 21, 2015) – Reducing dairy cow stress and maintaining good health is essential to help sustain a consistent and high level of milk yield. A research study presented at the American Dairy Science Association – American Society of Animal Science Joint Annual Meeting in Orlando, Florida, demonstrated that the nutritional specialty product OmniGen-AF®, from Phibro Animal Health Corporation, can help protect dairy cows from the effects of heat stress by supporting normal immune function.
The research was presented by Nicole Burdick Sanchez et al., (#T25) and was selected as a “Presidential Pick” at the meeting by Debra Aaron, Ph.D., ASAS President and University of Kentucky animal sciences professor. The heat stress poster presentation was one of just 16 studies to receive this prestigious honor from more than 1,500 abstracts presented at the meeting.
The objective of the research was to study the differences in response of OmniGen-AF- fed dairy cows to various hormonal challenges when housed at different temperature-humidity indexes (THI). Two groups of Holstein cows were housed in temperature-controlled modules, with THIs set less than or greater than 72, the level at which dairy cows begin to experience the effects of heat stress.
Blood samples and rectal temperatures were monitored during the 10-day study, which was conducted at the University of Arizona, Tucson, in collaboration with the U.S. Department of Agriculture, Agricultural Research Service, Livestock Issues Research Unit in Lubbock, Texas. Results showed a reduction in stress hormones in the supplemented cows versus the control group. Researchers concluded that supplementing lactating dairy cows with OmniGen-AF may help prevent the negative effects of heat stress on infection-fighting white blood cells.
This research reinforces earlier Phibro and university studies demonstrating the positive impact of feeding OmniGen-AF on dairy cow health and milk production during periods of heat stress.
This was one of 13 studies presented by Phibro and other researchers on products and technologies developed and marketed by Phibro in select markets around the world.
