Abstract

Throughout history, dairy cows have made a significant contribution to human health and nutrition, and from an economic point of view, the dairy cattle breeding industry is the largest component of animal breeding in most parts of the world. During the transition period, the demand for energy and nutrients, fetal growth, milk, and colostrum production, which is associated with hormonal changes, increases dramatically, the management of cows during the transition period should be aimed at reducing the Negative energy balance by feeding through special diets. Reducing mineral deficiencies that lead to milk fever and other metabolic diseases, as well as reducing fat mobilization that leads to ketosis and fatty liver, are nutritional goals of the transition period. The main goal in dry cow management programs and calving expectancy is to minimize the changes associated with reducing feed intake, because feed intake is an essential characteristic of health and production. However, it is very important to pay attention to glucose supply for ruminants. Using technologies to protect nutrients in the rumen environment will be able to provide the nutrients needed by the animal. Feeding protected glucose is becoming an alternative strategy for increasing glucose and energy supply in dairy cows, and animal response to supplementation is a function of the animal's production status and the nature of the supplement.
