Trace minerals and their importance in sheep nutrition

A recent article delves into the crucial nutritional requirements of sheep, underscoring these ruminants’ susceptibility to copper toxicity.

“Trace Minerals and Sheep Nutrition” is an article authored by Robert J. Van Saun and published in Veterinary Clinics of North America: Food Animal Practice.

In the article, Van Saun emphasizes that while sheep require all trace minerals, they are particularly sensitive to copper toxicity, underscoring the need for their diets to be “carefully” formulated.

Robert J. Van Saun, DVM, MS, PhD, serves as a professor in the Department of Veterinary and Biomedical Sciences at Pennsylvania State University. His areas of expertise include ruminant nutrition, small ruminants, llamas, and alpacas, as well as metabolic diseases and the interplay between nutrition and reproduction.

In this article, Van Saun navigates through several studies in the field, including the latest report from the National Research Council (NRC) (2007), which highlights certain nutritional requirements of sheep.

Similarly, it is noted that the required amount of trace elements for sheep is determined through factorial models, which take into account “maintenance, wool production, pregnancy, growth, and lactation.”

Geographical variability stands out as a key point, as the required quantities must be adjusted to the availability of elements in different dietary sources and address this diversity. Therefore, the importance of adjusting needs according to the region to ensure adequate nutrition is emphasized.

Furthermore, Van Saun reviews various relevant clinical points, such as the fact that a copper-molybdenum ratio in the diet of 6 to 8:1 “ensures adequate copper availability,” and that trace mineralized salt for sheep “should contain less than 30 ppm of copper and up to 90 ppm of selenium.”
