DAIRY ULTRA 100
Research Trial
Research conducted at the University of Kentucky compared DAIRY ULTRA 100 to Energy Booster 100 as bypass fat and energy sources. Performance measures of cows receiving Merrick's DAIRY ULTRA 100 were equal to cows receiving Energy Booster 100.

Trial Design
The trial was designed to evaluate lactating dairy cow performance achieved by supplementing diets with prilled tallow or free fatty acids of tallow under conditions of heat stress during July and August. Twenty-six cows (12 first lactation and 14 multiple lactation cows) were assigned to treatments based on lactation number, days in milk, and production.
Cows were housed in tie-stalls and were fed isonitrogenous diets as TMR. During a two-week acclimation period, DAIRY ULTRA 100 or Energy Booster 100 were gradually added to the diet to provide 1.0 lb of supplemental fat per day. Data were collected for the next 3 weeks every morning and evening for milk production, milk composition and dry matter intake.
Trial Results
Data from the trial indicate that no significant differences in performance characteristics exist between lactating cows fed supplemental rumen bypass fat consisting of prilled tallow (Merrick's DAIRY ULTRA 100) or free fatty acids from tallow (Energy Booster 100).
