What is a TMR feed mixer? 

The TMR feed mixer is a new type of equipment that mixes roughage, concentrate feed, trace elements and other additives according to the nutritional needs of cows at different feed stages. So as to achieve the purpose of scientific feeding. Then, the following is to introduce the function and principle of TMR feed mixer.

The TMR feed mixer has a high precision electronic weighing system, which can accurately calculate the feed and effectively manage the feed bank. Not only is the total weight in the feed mixer displayed, but the feed intake of each animal is also measured, especially the accurate weighing of some trace ingredients (such as nitrogen additives, artificial additives and syrups), so as to produce high-quality feed and ensure that every bite of the dairy cow's diet is a full-priced diet with a stable ratio of concentrate to coarse and consistent nutrient concentration.

TMR feed mixer can improve the mixed feed and yield, because various feed and trace elements can be mixed into the mixer to make the feed ingredients determined by the selected feeding formula; Effectively ensure the animal's demand for protein, is a large increase in milk production, milk quality has been greatly improved, reduce metabolic diseases.

How the TMR feed mixer works?

Working principle of TMR feed mixer: TMR feed mixer consists of a U-shaped horizontal cylinder, a stirring shaft, the shaft is inside and outside double screw belt. The stirring shaft rotates, so that the inner and outer spiral belt turns the material in a large range, the inner spiral belt moves the material to both sides, the outer spiral belt moves the material from both sides inward, so that the material is mixed back and forth, the other part of the material is driven by the spiral belt, along the axial radial movement, thus forming a convective cycle. The above movement of stirring, the material in a short time to obtain rapid uniform mixing.

Advantages of TMR Feed Mixer:

1. The loss rate of non-stirred round bale forage fed directly is as high as 30% due to feeding-foraging, discarding and trampling behavior of livestock. However, the forage loss is greatly reduced after feeding with vertical TMR and other feed mixing.

2. According to the nutrient diet formula ingested by livestock at different production stages, the livestock is fed after vertical TMR stirring to achieve the highest cost and highest nutrient intake effect. For example, beef cattle have lower nutritional requirements after weaning and during the second trimester, but higher nutritional requirements in the later trimester, calving, early lactation and during childbirth, while reserve heifers and growing young calves have higher nutritional requirements.

In addition, the quality and nutrient composition of herbage are different due to the influence of different kinds and varieties, the maturity stage, straw length and climate at the time of harvesting. By analyzing herbage and mastering the changes of cattle production stage and nutritional requirements, using TMR feed mixer is an effective way to mix herbage and feed in the most economical and effective way, so that cattle can get the best nutrition requirements and thus reduce the cost. In beef cattle, for example, conventional feeding has reduced hay use by 30% to 50% compared to the vertical TMR stirring feeding method. Experience shows that using vertical TMR can save 20%-30% of the annual feed cost of optimized forage.
