Is Magnesium Supplementation an Effective Nutritional Method to Reduce Stress in Domestic Pigs? A Systematic Review

Abstract: In commercial pig production, stressful events are common and can have detrimental impacts on the pig's health and welfare, as well as on the performance of the farm. Supplementary magnesium may reduce stress, and subsequent harmful and aggressive behaviors, that occur during stressful events, such as regrouping. However, reports on the efficacy of this treatment are mixed. We aimed to systematically review the studies in which magnesium was given to pigs to examine the effects on measures of stress. Of the 16… Show more

“…A special role therein plays magnesium, as almost all animals were diagnosed to have a clinical hypomagnesemia in this study. Some studies have proven beneficial effects of magnesium supplementation on different maladaptive behaviours in pigs [ 52 – 54 ]. However, another possible explanation for the high number of affected animals is that an adaptation of the reference values is needed, as usually, reference values are set from studies of limited pig population size and given ongoing advancements particularly in genetics and feeding may need regular adaptions.…”

“…It is complex for animal aggression which underlying biological regulatory mechanism. Currently, several strategies have been explored to reduce aggressive behavior in pigs, including genetic selection [ 5 ], nutritional supplementation [ 6 ], early-life socialization [ 7 ] and the use of pheromones [ 8 ]. Among these approaches, genetic selection holds the greatest potential.…”
