  1. The Jaylor Advantage Dr. Alan S. Vaage Ph.D. Ruminant Nutritionist

  2. 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.

  3. 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.

  4. 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

  5. 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%.

  6. 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.

  7. 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.

  8. Dairy cow eating behavior

  9. Role of TMR Mixer • Combine disparate ingredients into a homogenous mix • Create a mix that resists separation by animals during eating

  10. 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)

  14. 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.

  15. 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.

  23. 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
