LEO Agriculture TMR Mixers: Frequently Asked Questions
Optimizing Milk Fat Content and Herd Health
Q: How can a TMR mixer impact milk fat content?
A: LEO Agriculture TMR Mixers promote optimal milk fat content through exceptional mixing uniformity and efficient processing of long forages.
Uneven Mixing: Poorly mixed TMRs can lead to areas with higher grain concentrations. Cows readily consume these areas, resulting in excessive grain intake and inadequate fiber from forages. This imbalance disrupts rumen health, causing sub-acute acidosis and ultimately, depressed milk fat production.
Improper Processing of Long Forage: If long forage particles (hay, straw, or silage) aren’t processed into a uniform size distribution, cattle can sort them out. This allows them to consume a diet with a higher concentrate-to-forage ratio than intended, again impacting rumen function and milk fat content.
LEO Agriculture Mixer Advantages
Q: What LEO Agriculture TMR mixer features contribute to optimal milk fat content?
A: Our innovative design elements ensure efficient mixing and proper long-forage processing:
Diamond-Cut Auger: Square-shaped augers knife configurations with strategically placed half blades effectively reduce long particles into a uniform mix that resists sorting during feeding. This ensures consistent nutrient intake throughout the herd.
Minimum Force, Maximum Efficiency: Our mixers achieve optimal processing with minimal force (horsepower) and processing time, minimizing potential forage damage. Preserving forage quality is crucial for maintaining rumen health and milk fat production.
Reduced Frictional Force: The auger flighting and Stainless Steel slide plate design minimize friction between feed and mixer surfaces. This protects medium-sized forage particles, which are vital for effective fiber digestion and sorting resistance.
TMR Mixer Maintenance and Best Practices
Q: How long should TMR mixer knives last?
A: Knife life expectancy depends on several factors:
Material: Steel knives dull and require frequent sharpening. Carbide-tipped knives are more resistant to wear but can chip and cannot be sharpened. Carbide-coated knives offer a good balance between wear resistance and self-sharpening capabilities.
Frequency of Use: More frequent mixing leads to faster wear.
Ingredients: Abrasive ingredients like chopped silage or sand in forages accelerate wear.
Recommendation: We recommend using carbide-coated knives for processing forages. Regularly inspect knives and replace them when dull or chipped to maintain optimal mixing performance. For vertical auger mixers, consider replacing a portion of the knives every 6 months for a machine making 2 mixes per day, focusing on those at the bottom (where most cutting occurs).

Heat Stress and TMR Management: While TMR mixer performance doesn’t directly affect heat stress, poor mixing and inadequate processing can worsen its effects on rumen health and milk fat production. Refer to the LEO Agriculture Nutrition Library article “Heat Stress? Sharpen Focus on Summer Feeding” for strategies to combat heat stress through TMR formulation and management.
TMR Performance and Nutrition
Impact on Feed Intake and Milk Production:
How does TMR mixer performance influence feed intake and overall milk production?
A well-mixed TMR with consistent nutrient distribution encourages optimal feed intake. When cows consume a balanced diet, they are more likely to eat to their full potential, leading to increased milk production. Conversely, a poorly mixed TMR can result in uneven nutrient intake, leading to decreased feed consumption and reduced milk yield.

Reducing Sorting Behavior:
What strategies can farmers employ to reduce sorting behavior in cows, even with well-mixed TMR?
Particle Length Management: Ensure proper particle length distribution to minimize sorting.
Feed Push-Up Frequency: Frequent feed push-ups help to prevent feed separation and encourage even consumption.
Cow Grouping: Group cows with similar feed preferences together to reduce competition.
TMR Consistency: Maintain consistent TMR formulation and mixing to reduce variations that might encourage sorting.
Particle Length Management:
How can farmers effectively manage particle length in their TMR to optimize rumen health and milk production?
Monitor Particle Length Distribution: Regularly analyze particle length distribution to ensure it aligns with recommended guidelines for your herd.
