Macromineral requirements for maintenance and growth in male and female hair sheep

Frontiers in Veterinary Science, 2023
A better understanding of the nutritional requirements of sheep, especially in terms of minerals, is crucial for improving production. We estimated the net requirements for Ca, P, K, Mg, and Na for gain (NCag, NPg, NKg, NMgg, and NNag) and maintenance ...
