Why does optimizing the dry period lead to high productivity?

A good dry period gives its results immediately after calving, when you get five to six liters of colostrum at the first milking.

The factor - cation-anion balance

A key role at this point is played by the balance of cations and anions, which is determined by the quality of the feed. This balance has an acidifying or buffering effect in the blood. If the balance is too low, the cow produces too little colostrum and begins to weaken in lactation. If the balance is too high, colostrum production is too high and there is a greater chance of disease of the milk-producing organs.

High colostrum production means a lower concentration of antibodies, or immunoglobulins, and therefore this leads to a lower quality colostrum for the calf and increases the risk of possible problems with its health status. Feeding in the last period of pregnancy appears as one of the most important factors, both for the development of the calf and for the future main activity of the cow - milk production.

> Nutrition and mineral supplements during the last month of pregnancy are important for the successful rearing of young animals. In this phase, the cow needs additional vitamins and minerals for calf growth, colostrum formation and self-maintenance.

Deficiencies in, for example, vitamin E and selenium are expressed in muscular dystrophy or weak calves. Delicious, fresh food is also essential to keep in mind. Food should not be too rich in energy and protein within 12-13% crude protein. If the crude protein content is too high (> 14%), colostrum production is too high after calving. The type of protein is also very important. The ratio between fast and slow fermenting protein is also very important for good colostrum quality.

Optimization of dry period

Because of all this, you should optimize the dry period and not underestimate it. It is important to check that your dry cows are consuming what they are being fed. In case of problems, consult your nutrition consultant immediately. Doing everything right will result in the production of high-quality colostrum, vibrant calves and a successful start to the cow's milk production.
