The first limitation in intake occurs around calving and at the day of calving marks the lowest intake of the year, with the highest expulsion of minerals and vitamins. Recovery from this low point is rapid under normal circumstances but the first two or three weeks are crucial since upsets at this time can precipitate metabolic disorders.
A common fallacy is that since feed intake is low in the first few weeks of lactation, giving more concentrates can easily increase the energy intake. In fact, whilst feeding concentrates below a certain level can cause a reduction in energy intake, beyond this level increases in concentrates may have little influence on energy intake since total feed intake is even further depressed.
It is important to remember that even on high concentrate diets cows still show the low intake and depressed energy intake characteristic of early lactation. It is therefore important to increase the mineral and vitamin status by feeding TMR Intensifier from calving.
Feed intake can be upset if the diet is of the wrong kind. For example, a deficiency of any of the essential nutrients protein, vitamins and minerals, usually has an immediate depressing effect on intake.
The formulation of TMR Intensifier revolved around the above discussion, where intake and the availability of the micronutrients supplied to the animal commercially comes into play.
