dc.description.abstract | Minerals constitute. part of the b.ody that plays a very impo.rtant role in maintaining body functions. Minerals play a rol,e in physiolo,gical processes, namely growth and health maintenance. Minerals play a role in physiological processes, namely growth and health maintenance. Mineral substitution in feed pla,ys an important role in livestock pro;duction through several mechanisms with different growth targets. Research on the addition of minerals to feed with a target of livestock production has been carried out with varying results. Minerals in increasing the growth / production of livestock through various pathways, namely: As a co-factor in the metabolic process of carbohydrates, proteins and fats, as cell cations, regulators of osmotic fluid and acid-base balance, and immunity through immune responses, which play a role in development and maintaining activity immune cells. The adequacy of minerals from ruminant feed depends on the geological structure of the soil where the forage is planted. | en_US |
