Detailed explanation of the function and principle of TMR feed mixer

What is a TMR feed mixer? TMR feed mixer is a new type of equipment which mixes the cut coarse feed, fine feed and trace elements according to the nutritional needs of dairy cows at different feed stages. So as to achieve the purpose of scientific feeding. Then, let's introduce the function and principle of TMR feed mixer.

TMR feed mixer is equipped with high-precision electronic weighing system, which can accurately calculate feed and effectively manage feed storehouse. It is necessary not only to display the total weight in the feed mixer, but also to measure the intake of each animal, especially to accurately weigh some trace components (such as nitrogen additives, artificial additives and syrup). ), so as to produce high-quality feed, and ensure that dairy cows consume a complete diet with stable concentrate-to-roughage ratio and consistent nutrient concentration every time.

TMR feed mixer can improve compound feed and yield, because after adding various feeds and trace elements into the mixer, the feed components determined by the selected feed formula can be made; Effectively ensure the demand of animals for protein, greatly increase the milk yield, greatly improve the quality of milk, and reduce metabolic diseases.

Working principle of TMR feed mixer: TMR feed mixer consists of a U-shaped horizontal cylinder and a stirring shaft with inner and outer double spiral belts. When the mixing shaft rotates, the inner and outer spiral belts turn over the materials in a large range, the inner spiral belt moves the materials to both sides, the outer spiral belt moves the materials inward from both sides, so that the materials are mixed back and forth, and the other part of the materials move along the axial and radial direction under the push of the spiral belts to form a convection cycle. Under the stirring of the above movement, the materials can be quickly and evenly mixed in a short time.

Advantages of TMR feed mixer:

1. Due to the feeding, abandonment and trampling behavior of livestock, the loss rate of forage directly fed with unmixed round bundles is as high as 30%, but after feeding with vertical TMR and other accessories, the loss of forage is greatly reduced.

2. According to the formula of nutritional diet ingested by livestock in different production stages, feed it after vertical TMR mixing, so as to achieve the effect of cost and nutritional intake. For example, the nutritional requirements of beef cattle are low after weaning and in the second trimester of pregnancy, but high in the third trimester of pregnancy, calving, early lactation and production, and high in reserve heifers and growing calves.

In addition, due to different species and varieties, different maturity, different straw lengths, and different climate effects during harvesting, the quality and nutritional components of pasture are also different. Through the analysis of forage grass, it is an effective way to grasp the changes of production stages and nutritional requirements of cattle and feed them with TMR feed mixer, which is an economical and effective way to mix forage grass and accessories, so that cattle can effectively absorb nutritional requirements and reduce costs. Taking beef cattle as an example, compared with the vertical TMR stirring feeding mode, the hay consumption of the latter is reduced by 30%-50%. Experience shows that the use of vertical TMR can save 20%-30% of the cost of optimized forage every year.
