How does stress affect livestock performance?

Stress has a significant negative impact on livestock performance, and the correct choice highlights this aspect very clearly. When animals experience stress, their bodies undergo various physiological changes that can adversely affect their overall health and productivity.

Stress can lead to reduced growth rates because animals may experience decreased appetite and reduced nutrient absorption. This deprives them of the essential energy and nutrients needed for optimal growth. Additionally, stress can hinder reproductive performance as it may disrupt hormonal balances necessary for reproduction, leading to reduced fertility and complications in breeding.

Furthermore, stress compromises the immune system, making animals more susceptible to diseases and infections. This can result in increased morbidity and mortality rates, further impacting livestock productivity. Therefore, understanding these effects is crucial for livestock management, as minimizing stress can lead to better growth, reproduction, and overall health outcomes in livestock.
