What are the main advantages of TMR?
- Enables the preparation of feeding rations for cows of a given yield, which will cover the demand for protein, energy, minerals and vitamins;
- The feed is properly mixed, what prevents the cows from “digging up”;
- We can diversify the fed feed, which in turn can reduce the cost of feed;
- Less effort spent on preparing feed;
- Better matching of feed to cows and their requirements;
- Increased milk yield;
- Improving the health of cows.
Factors affecting the quality of TMR:
- Division of cows into food groups. According to the recommendations, there should be at least 3 groups: up to day 120 of lactation, from day 120 until dry, and dry cows;
- Each nutritional group gets a properly prepared TMR, tailored to its needs;
- Cows in the herd should be of equal genetic potential;
- The feed should be of very good quality.
How to prepare TMR?
For TMR you should use high-quality silage with an increased DM content. TMR should contain in s.m. about 16-18% crude fiber and about 70% of the roughage cut into 3-4 cm chaff. It is assumed that the dry matter content should be between 40 and 50%. After mixing, the feed should crumble, not clump.
A lactating cow will consume a maximum of about 23 to 29 kg DM, while a dry one 11-13 kg.
The implementation of the TMR system is often associated with high costs related to the modernization of the barn or the purchase of equipment. After some time, each farmer will notice the advantages of the system, not only in terms of noticeably greater milk yield and health of the cows, but also in terms of time and money saved.
