摘要: Abstract INTRODUCTION THE ingestion by hens of many plants belonging to the order Malvale, or fats derived from such plants, gives rise a pink discoloration whites eggs after storage, as shown Sherwood (1928 (1931) for cottonseed oil and meal, Lorenz, Almquist Hendry (1933) Malva parviflora. Schaible Bandemer (1946) showed that are caused iron diffusing yolk chelating with conalbumin white give iron-conalbumin complex. The disorder is accompanied mottled, discolored appearance yolks also pasty condition when maintained at low temperature. Affected have higher water content than normal. pH values white, normally 6.5 9.0 respectively in stored eggs, tend converge. suggested effects …
