Trial Overview:
Cattle Evaluated For:
Feeding Rate:
500 mg/head/day
Trial Type:
Producer Record Review
Environment:
Summer (80–102°F)
Duration:
30 Days On Feed
Commercial dairy observations from Missouri evaluating milk production response after feeding 454 during the summer.
Based on Missouri dairy trial observations from June through August 2020.
Initial Milk Response
Average milk increase in the first 7–14 days
30-Day Response
Milk increase observed after 30 days on 454
Feeding Rate
Per head per day during the trial period
Heard Size
Commercial dairy cattle on 454 during trial
These Missouri dairy observations evaluated production response after feeding 454 at 500 mg per head per day. Across small trials and reviewed producer records, herds showed an average milk increase of 3 pounds per head per day within the first 7 to 14 days, with increases of up to 5 pounds per head per day after 30 days on 454.
In these Missouri dairy observations, milk production responded quickly after cattle began receiving 454. Initial production gains were observed within the first two weeks, and larger gains were reported after 30 days on feed. This suggests that 454 may help support production stability and performance during summer conditions when dairy cattle are under added environmental stress.
Milk production increased within 7–14 days and continued improving through 30 days on 454.
Based on Missouri dairy observations (June–August 2020).
Although overall herd health is harder to quantify than milk production, producers and dairy veterinarians reported meaningful long-term improvements after about one year on 454. These observations included:
Because these are field observations rather than controlled measurements, I would present them as reported herd health observations, not hard trial endpoints.
