What impact does lack of energy have on lactating cows?

Lack of energy intake during lactation leads to a significant decrease in milk production, as energy is crucial for the synthesis of milk components such as fat, protein, and lactose. When cows do not receive adequate energy, they cannot meet the metabolic demands of lactation, resulting in lower milk yields.

Additionally, energy deficiency can lead to health issues in lactating cows. Insufficient energy can cause negative energy balance, leading to conditions such as ketosis or fatty liver, which can have serious implications for the overall health and welfare of the animal. Health issues may also result in reduced reproductive efficiency, as energy is vital for maintaining reproductive functions. Therefore, the consequences of inadequate energy intake extend beyond just milk production, impacting the overall health and productivity of the cows.
