How Can Cattle Farms Better Use TMR Feed Mixer

1. Choose a suitable mixing truck, which is the key to popularizing the application of TMR technology. A suitable mixing truck should be selected according to the type of ration, the breeding scale of the cattle farm, and the building structure of the cattle farm. Common TMR mixer trucks include vertical, horizontal and traction mixer trucks. Among them, the vertical mixer has good mixing effect, high mixing uniformity and long service life of the machine.

    2. Reasonable grouping and timely transfer to groups. Reasonable grouping is a necessary supporting measure of TMR technology. If it is not divided into groups, fat cows will be produced, which will seriously affect the performance of the cow's milk production. The number of groups of cattle depends on their size and existing equipment. Generally small dairy farms (less than 300 heads) can be directly divided into lactating dairy herds and dry dairy herds, each with a TMR design; medium-sized dairy farms (300-500 heads) can be divided into early, middle and late herds according to the lactation stage And dry dairy herd; large cattle farms (more than 500 heads) can subdivide cattle into new herds, high-yield first-feet herds, high-yield and post-production herds, herds of abnormal body conditions, herds of dry milk, dry cows For late-milk herds, etc., design 6-7 TMRs respectively. In the specific grouping process, it can be flexibly controlled according to the individual situation of the cattle and the size of the herd, and adjusted or merged in time. When adjusting the group transfer, it is necessary to transfer in a small group, preferably during the feeding.

    It is very important for dairy cows to be divided into two groups: pre-dry milk (dry milk to 30 days before delivery) and late dry milk, because these are two completely different stages. The reserve cattle should be subdivided, and the size of each herd should not be too large, usually about 10, and the individual conditions in the group are required to be consistent. As the age of cattle increases, the size of the group can be appropriately increased.

    3. TMR mixing technology, the cutting length of roughage is very important for the preparation of TMR rations, and affects the mixing effect of TMR. Generally, the suitable length of silage is 2-3cm, but 15%-20% of the length is required to exceed 4cm, and a certain amount of 5cm long hay should be added. The water content of TMR should be 40%-50%, and the water content of TMR should be measured before mixing. The feeding sequence of TMR is generally coarse first and then refined, that is, hay-silage-dregs-refined materials. Stir while adding the materials, and then stir for 4-6 minutes after all the materials are added. Generally, the mixing time of each batch is about 15 minutes. If the mixing time is too long, the roughage in the TMR may be mixed too finely, and the effective neutral detergent fiber is insufficient; if the mixing time is too short, the uneven mixing will cause uneven nutrition and affect the feeding effect. The TMR mixer should be 60%-70% of the full load when mixing. If it is too much, the mixing will be uneven.

    4. TMR feeding trough management, TMR feeding should evenly put in the feed to ensure that the cattle have enough time to eat. Generally dry cows and growing cows are fed once a day, lactating cows are fed twice a day, and can be fed 3 times in summer. In the sultry summer, in order to prevent the feed from depositing and heating, the feed should be turned 2-3 times a day, and the remaining feed should be cleaned up every day.

    5. The requirements of TMR technology on the cowshed. The loose cowshed is the cowshed used in modern cattle farms at home and abroad. It is suitable for the application of TMR technology and can greatly improve the labor productivity of the dairy farm. Generally, the width of the cowshed is more than 20cm, the length is 60-120m, and the width of the feeding channel is 4.0-4.5m. The standard barn is based on raising 200-400 cows.
