“…This interaction was a result of the tibia ash being significantly depressed when magnesium was added to the diets containing soft phosphate. This increased growth response from supplemental magnesium agrees with the findings of Chicco et al (1967), and adds support to the theory that magnesium, under certain conditions, can spare calcium. This depression barely met the level of statistical significance Magnesium supplementation of diets containing either soft phosphate or monosodium phosphate resulted in a slight reduction of body weights in ten of the twelve diets fed (Table 1).…”

“…Damron and Harms (1968) used builders' sand to bring diets up to 100 percent. Chicco et al (1967) used solka-fioc for the same purpose and Waldroup et al (1965) utilized pulverized oat hulls. In an attempt to regulate the nutrient intake of laying hens Gleaves et al (1963) used polyethylene fluff as a volume control ingredient.…”

Two experiments using a total of 1260 broiler-type chicks were conducted to evaluate the use of diluents in phosphorus assays. Two formulations were used with either solka-fioc or sand as a diluent and a third formulation had no diluent added. Although the diets without a diluent were more concentrated, the results obtained with them were not significantly higher than those with diluents. The diets containing sand resulted in the most uniform data. Solka-fioc appeared to depress growth. Of the formulations studied, sand appears to be desirable in assay work with practical-type diets.

“…magnesium in the diet caused reduced growth in young chicks (Chicco et al, 1967) while 6,400p.p.m. caused reduced growth and high mortality (Nugara and Edwards, 1963).…”

Magnesium Deficiency, Requirement and Toxicity in the Young Japanese Quail

1976

Studies of magnesium deficiency, requirement and toxicity in the young Japanese quail (Coturnix coturnix japonica) were conducted. Day-old birds were fed an adequate purified diet containing 35% soy protein to 2 weeks of age. Residual magnesium in the diet without any added magnesium salts was 21 p.p.m. magnesium was supplied by graded amounts of MgSO4 to a total of 11 levels ranging from 125 to 2,000 p.p.m. Deficiency signs included poor growth, and occasionally excitability, gasping and convulsions. Most mortality occurred during the first 7 days. The maximum dietary magnesium concentrations that produced the minimal significant deviation from normal values for mortality, body weight, hemoglobin and tibia ash was 225, 200, 250 and 250 p.p.m., respectively. Based on these measurements, 300 p.p.m. magnesium is considered adequate to meet the young quail's requirement under the conditions of these experiments. With 2,000 p.p.m. magnesium, the only adverse effect was an increase in mortality. Between 200 and 1,000 p.p.m. magnesium there was a linear relationship between concentration of magnesium in the tibia and the log of the concentration of dietary magnesium. This suggests that tibia magnesium concentration might be useful for bioassay of magnesium in foodstuffs.
