The effects of feeding on the milk production of dairy cows13.01.2015
At a milk yield of 4000 kg, 500 kg of dry matter is expelled from the body, at a milk yield of 5000 kg, more than 635 kg is expelled. Therefore proper feeding of cows is essential for maintaining a high level of milk productivity.
Correct feeding gives the desired level of productivity, maintains the health and reproductive functions of the cows, and is economical. For highly productive cows, it is recommended to balance and control their diet with no less than 25 nutrients and bioactive substances. Below is a list of the main indicators that must be regulated when feeding dairy cows.
Nutritional value of the diet
All nutrients in the body's metabolic processes are interrelated. Deficiency or excess of any particular nutrient will inevitably alter the way the body uses other nutrients.
It is important to remember that a cow's requirement for nutrients and the proportion of these nutrients in the diet change depending on the cow's physiological condition, i.e. the stage of lactation, pregnancy, dry period.
