Using a tmr ration formulation is crucial for optimum performance in dairy cows. Good feeding management practices include monitoring forage and feed inventory, testing forages and feeds and updating ration formulations based on milk production, milk fat and protein percentages, changes in the price of current feeds and the availability of suitable forages. Checking the moisture level of forages on a regular basis is essential for the successful implementation of a TMR system.
Misconceptions about tmr cow feed
There are many myths surrounding TMR cow feed, but one of the most common is that the only difference between it and conventionally produced TMR is the amount of forage it contains. A proper balance is crucial for the health of the cow and milk production. The only way to ensure this is to accurately weigh TMR at each feeding. Many farmers purchase sorted TMR to ensure that the cows are getting a balanced diet. However, it is important to note that this method requires more effort and expense.
While TMR is an excellent option for boosting feeding efficiency, it has its drawbacks. The one-group system limits the flexibility of ration formulation, while the three-group system allows higher-producing cows to receive lower-cost forage. Another issue is that feed costs are higher with the one-group TMR system. On the other hand, late lactation cows should be fed higher amounts of forage in TMR.
It may seem that TMR cow feed is a high-forage diet, but this is not necessarily the case. Cows need adequate levels of fiber and long forage in their diets to function optimally. To aid in this process, they regurgitate their feed and secrete saliva, which buffers the rumen environment and helps the bacteria digest the forages. Additionally, rumination results in the production of five to six pounds of saliva each day. Nutritionists work to balance TMR cow feed rations, while providing adequate amounts of effective fiber.
Cost of equipment to implement a tmr system
To effectively implement a TMR system in a freestall operation, a farmer must consider costs associated with forage and feed inventory. He must conduct tests to determine forage and feed quality and regularly update ration formulations based on changes in milk production, fat content and protein levels, and price changes for current feeds. To ensure a successful TMR system, he must check forage moisture on a regular basis.
TMR systems can be costly to implement and operate. For example, fence-line feeding is required, requiring the implementation of fencing and a centralized feeding infrastructure. In addition, a TMR system requires processing of forage at harvest and mixing. While not as time-intensive as chopping in the field, the mixers can be expensive and require moderate maintenance. Additionally, it is vital to follow manufacturer guidelines for mixing and blending.
The cost of equipment to implement a TMR system for cow feed can be high, especially if the farm feeds only one group of cows. Moreover, cows in a single group of TMR systems may need supplemental grain. The amount of supplemental feed used may vary depending on the level of concentrate in the ration. But keeping the ingredients in a TMR system will increase its benefits over conventional rations.
Alternatives to adding water to a tmr mix
While avoiding excessive amounts of liquid feed, TMR mixes need moisture in order to separate. Water, which forms on the surface of particles, is the most effective moisture source. Adding water to a TMR mix should be limited to around 60% dry matter for optimal results. If you add more water, do so gradually. You can also add liquid feed to a TMR mix to reduce sorting, but this method can be risky.
The addition of water decreases the DM content from 81% to 64%, which will reduce cud chewing and increase neutral detergent fiber intake. However, water will not change the milk fat content, dry matter intake, or production. The added water is not harmful for the health of your dairy cows. For this reason, TMRs can only be given once every 3 to 6 months.
Other benefits of TMR include reduced labor in the barn and less time in the parlor. TMR allows you to feed more nutritious commodities with fewer labor hours, and it also facilitates feeding commodity feeds. The downside is that TMR rations are less cost effective if they are over-mixed. However, if your farm is large, you can minimize this problem by keeping the components of your TMR in constant proportions.
