The Jaylor Advantage
  • The ability to process long forage into a uniform mix in a minimum amount of time, to create dairy rations with optimal levels of effective fiber that are resistant to sorting.
why total mixed rations tmr
Why Total Mixed Rations (TMR)?
  • Traditional dairy feeding fed forages and grain (supplements and minerals) separately.
  • Grain fed to milk production in the parlor, and later using computer feeders.
  • With breeding improvement, peak cows required 50-60 % grain, and >30 lbs/day, causing health and production problems.
  • Grain meals greater than 8 lbs causes digestive upset and health problems.
  • TMR keeps all ingredients in proportion.
physically effective fiber
Physically effective fiber
  • At the same time as milk production and grain feeding increased, ensiling experts promoted smaller forage particle size to improve silage packing and fermentation.
  • Problems arose with depressed milk fat, sub-acute ruminal acidosis (SARA) and displaced abomasums.
  • Feeding some long forage alleviated part of the problem
why put long forage into a tmr
Why put long forage into a TMR?
  • Long forage provides effective fiber to promote chewing, prevent digestive upset and increase milk fat production .
  • However, it must incorporated into a particle size distribution that resists separation.
  • Even longer material in bunker silos must be incorporated adequately to provide a uniform mix that will also resist sorting.
  • In beef cattle, incorporating baled forage into a TMR reduces wastage and improves performance up to 30%.
sorting behavior
Sorting behavior
  • Inherent cattle behavior (for ingredient selection while grazing).
  • Ingredient preferences.
  • Learned behavior, hard to stop once successful.
  • Strongest in late lactation and older cows.
  • Aided by excessively long particles in TMR.
effects of sorting behavior
Effects of sorting behavior
  • Affects both sorter and non-sorters.
  • Increases intake of rapidly fermented ingredients in sorters.
  • Low milk fat, increased milk protein, SARA, feet problems, displ. abomasums, fat cows.
  • Decreases the energy content of remaining diet for non-sorters.
  • Thin cows, decreases peak milk production.
role of tmr mixer
Role of TMR Mixer
  • Combine disparate ingredients into a homogenous mix
  • Create a mix that resists separation by animals during eating
particle characteristics affect mix
Particle characteristics affect mix
  • Particle size, shape, density, #/kg
  • Inter-particulate forces (electrostatic, hydroscopic, hydrophobicity)
  • Best mixing with uniform particle size, shape and density (e.g. granular fertilizer, commercial feed)
  • Differences create tendency to unmix and separate (esp. effective fiber)

test weighing accuracy and precision
Test weighing accuracy and precision
  • Clean and inspect weigh bars
  • Find a helper
  • Weigh yourself over each weigh bar with mixer empty. Repeat with mixer full.
  • Average of empty and full weights should be within 10 lbs.
  • No weigh bar should differ consistently from others, high or low.
how do we measure mix uniformity
How do we measure mix uniformity?
  • Mix uniformity ultimately involves three components, and thus two-three measures
  • First, ensuring we have equal distribution of all ingredients (esp. grain (starch) vs. forage or digestible fiber) (markers, chemical analysis?).
  • Second, ensuring we have equal distribution of all major nutrient groups, i.e. protein, fat, fiber, mineral (chemical analysis).
  • Finally, ensuring we have a uniform and acceptable particle size distribution that will prevent sorting (PSPS) and unmixing.

ingredient sequencing vertical
Ingredient sequencing (Vertical)
  • Add long forage first (esp. baled hay. Include liquid or water to aid processing)
  • Follow with silage and/or wet by products
  • Add protein supplement and grains
  • Pre-weigh and add premixes and specialty ingredients with grains
  • Generally add liquid ingredients last
