ABS>The ash of egg shells from White Leghorn hens fed ration contains 0.049 plus or minus 0.020% strontium and the ash of bones of chicks contains 0.040 plus or minus 0.012%. When these hens are fed the same breeder ration with 0.2% strontium added, the contentration of strontium in the ash of the egg shells increases by a factor of 40 to 50 within 3 days, but no further increase occurs after that time. During the posttreatment period, the hens release some of the body stores of strontium to the eggs. After 50 days, the strontium content of the eggs decreases to approximately 2.5 times the natural level. Chicks hatched from eggs containing large amounts of strontium are able to metabolize appreciable amounts of this element. However, the strontium content of the ash of chick bones decreases to the natural level in 2 months or less because of elimination and dilution caused by rapid growth. Strontium to calcium ratios, calculated from approximate calcium percentages, indicate that there is no discrimination against strontium between the feed and the hen's eggs. The chick embryo shows some selectivity for strontium relative to calcium. (auth)
