“…Mg passes through the intestinal epithelium by one of three possible mechanisms: passive diffusion, solvent drag, and active transport (Kimura, 2007). Rat studies have made evident that the mode of Mg transport changes from mainly a passive mechanism in young animals to mainly a carrier-mediated mechanism in the adult animals (Meneely et al, 1982).…”

“…In humans, although Mg absorption increases with each increment in intake, fractional Mg absorption falls progressively so that absorption as a function of intake is curvilinear (Fine et al, 1991). Intestinal Mg absorption is augmented to some extent by vitamin D and its metabolites because of the chemical similarity of Ca and Mg (Kimura, 2007). However, no convincing evidence is available suggesting that the intestine adapts to a chronic low or high Mg intake, as it does with Ca (Fine et al, 1991).…”

“…In broilers, the main site of absorption of Mg was reported to lie between the lower duodenum and the lower jejunum (Van der Klis et al, 1990). Mg is endogenously excreted in both urine and faeces (Matsui, 2007), and excretion with urine is the main regulator of Mg body homeostasis (Taylor and Kirkley, 1967;Kimura, 2007). The primary sites of Mg secretion into the intestine were found to be the duodenum and the upper ileum (Guenter and Sell, 1973;Van der Klis et al, 1990) however, some Mg secretion also occurs in the rectum (Van der Klis et al, 1990).…”

“…The effect could be the result of the acid-base balance change in the body (Nelson et al, 1981). As Mg intake increases, P absorption progressively decreases (Fine et al, 1991), possibly because of formation of insoluble Mg-phosphate complexes (Kimura, 2007). Increasing dietary Mg levels could interfere directly with the process of calcification, leading to an increase in the incidence of leg problems (Atteh and Leeson, 1983a) and a decrease in bone ash in chicks (Nugara and Edwards, 1963).…”

Magnesium has essential functions in cellular metabolism and bone development. Its actions are closely linked to calcium and phosphorus, making the achievement of the right proportion of these elements in diets an important issue in poultry nutrition. The magnesium requirement of poultry has rarely been studied and most studies conducted are more than 35 years old. Despite the fact that magnesium is adequately present in most plant-based diets, supplemental magnesium may positively affect poultry meat quality and body weight at certain developmental stages. However, excessive dietary magnesium could influence calcium and phosphorus availability and metabolism through different mechanisms. Understanding the effects of supplemental magnesium on the availability and metabolism of other dietary constituents and vice versa is important for formulating balanced diets and achieving maximal performance in poultry. Here we review this complex, insufficiently explored issue.

“…Liu et al (2007), using serum Mg, reported higher bioavailability values for organic Mg (L-aspartate) compared to inorganic Mg (MgO) sources. However, serum Mg concentration may be influenced by changes in serum pH, serum albumin, and other anionic ligands (Kimura, 2007). It also should be emphasised that the values based on growth, bone, or blood criteria provide only relative values of Mg availability and are not quantitative.…”

This experiment was conducted to determine the effect of inorganic and organic sources and levels of magnesium (Mg) supplementation on plasma, tibia, meat and liver Mg concentration and mechanical properties of bones in broilers. A total of one day old 450 broiler chicks were used and assigned to six experiment groups each having five replicate, randomly. There were 15 chicks in each replicates. In the experiment magnesium sulphate (MgSO 4 ) was used as inorganic Mg source and magnesium proteinate was used as organic Mg source. Experimental diets were supplemented provide 0 (control), 0.2 and 0.4 % Mg levels inorganic and organic Mg source of basal ration, and experiment period was six weeks. Main effect of Mg source and source x level interaction effect had not significant on plasma, liver, breast and thigh meat Mg concentration. While treatments did not significant effect on liver, breast and thigh meat Mg concentration, the main effect of Mg levels was significant effect on plasma Mg concentration. Plasma Mg concentration which were fed with ration added 0.2 and 0.4 % Mg level was higher than the control group. Tibia Ca concentration which were fed with ration added organic*0.2 and 0.4 % Mg levels were higher than the other groups. Tibia P concentration of organic Mg source fed with the group were higher than the inorganic source. The highest tibia Mg concentration were found to fed with organic*0.4 % Mg level of group. Tibia shear force and tibia stress which were fed with ration added 0.2 and 0.4 % Mg levels were higher than the control group. Supplementation of Mg in broiler diet was increased plasma Mg concentration and tibia shear force and also, tibia Ca and P concentration of organic Mg source fed with the group were higher than the inorganic Mg source.
