What are common signs of nutritional deficiencies in livestock?

The presence of poor growth and increased disease susceptibility is indeed a common sign of nutritional deficiencies in livestock. When animals do not receive adequate nutrition, their overall health suffers, leading to suboptimal growth rates and a weakened immune system. This increased vulnerability can manifest as a higher incidence of illnesses, as nutrients are essential for maintaining bodily functions, including immune responses.

Proper nutrition is critical for growth and immune function. For example, deficiencies in vitamins and minerals can impair biological processes necessary for development and disease resistance. Conversely, livestock that receive balanced diets are more likely to thrive, exhibit good growth, and maintain resilience against infections and diseases.

The other options reflect positive conditions or outcomes rather than signs of nutritional deficiency. For instance, increased feed intake and weight gain typically indicate good nutrition and health, while enhanced coat shine and activity levels signal proper nutrition and well-being. Similarly, consistently high reproductive performance is a sign of a well-nourished and healthy animal, rather than an indication of any nutritional issues.
