“…Grant-Frost and Underwood (1958) reported that in rats .5% zinc depressed food intake and therefore body weight. Stewart and Magee (1964) observed that .75% zinc decreased calcium retention, phosphorus, and magnesium in the rat. In chickens, 1% zinc adversely affected chick growth and feed efficiency (Roberson and Schaible, 1960).…”

Two experiments involving 124 Single Comb White Leghorn (Hy-Line) laying pullets and hens were conducted to determine the effect of zinc toxicity on bird performance. Twenty milligrams of zinc per gram of diet fed for 5 days significantly lowered fertility and hatchability of pullet eggs collected 14 to 28 days after the 5-day zinc feeding period. Zinc significantly depressed body weight on the day 5 of zinc feeding and significantly lowered egg poroduction from 0 to 4 weeks of test. Egg production from 4 to 12 weeks, feed conversion from 0 to 12 weeks, final body weight, and livability were not significantly affected. Hens fed the supplemental zinc for five days had depressed egg production from 0 to 4 weeks. Egg production from 4 to 12 weeks, feed conversion, final body weight, and livability were not significantly affected. Compared to their respective controls, 2% supplemental zinc fed for 5 days significantly improved hen but not pullet egg weight. Hen eggs collected 28 days after hens received the zinc diet contained significantly less potassium, copper, and zinc than the controls.

“…This result seemed to be surprising in view of the fact that fish does not contain much more calcium than meat. Since high levels of dietary zinc, par ticularly in the presence of low calcium intake, have been reported to decrease bone minerals [11] the zinc content of fish was examined and compared with th at of m eat. Six samples of cod fillet contained 2.9 (standard error: 0.06) mg zinc/kg, as against 42.1 (0.74) mg zinc found in m eat.…”

“…Studies in animals reported on this interaction and the effect of Zn on Mg in bacteria has been reported [22]. High intakes of Zn inhibited the intestinal absorption and utilization of Mg in young rats and the addition of Ca and P decreased the bone levels of Mg even further [23]. In another animal study, Zn decreased Mg absorption but this effect was not as great as the effect of Zn on Ca absorption [24].…”

“…sorption of both Zn [23], and of Mg [33]. In contrast, in humans, increasing the Ca intake 10-fold, from 200 mg to 2000 mg/day, did not confirm these effects of Ca on Zn absorption [34], nor the effect of Ca on Mg absorption [27].…”
